In this blog post, we’ll go over the 100 RDBMS important questions you’re likely to be asked during an interview and how you should answer them. Also, consider joining a credible SQL certification course to sharpen your skill-sets.
Let’s get started with the RDBMS interview questions and answers. This series of Oracle RDBMS important questions will cover the in-depth information of relational DBMS.
We have classified them into the following sections:
SQL Server Training & Certification
Below is the quick list of Oracle RDBMS interview questions
Ans:- It helps in storing or managing data across multiple tables. The best part is that you can define relationships among different data entries using tables. Relationships are generally expressed through values, not pointers.
Ans:-It defines the relationship among different databases and how they are connected. When multiple databases are connected, it creates flexibility and can be used within a software app as needed.
Ans:-Each relation in an RDBMS is given a “Name” that will be unique among others. There are rows and columns in each relation columns represent attributes and rows as Tuples.
Name => Attriutes => Tuples
Ans:-It is a data organization process where data is organized in such a way that it can minimize redundancy. It divides the database into multiple tables and defines logical relationships among them.

Ans:-Each has its objectives and purpose. So, you must understand them one by one before implementing it with the database.
1NF , 2NF, 3NF, 4NF, 5NF, BCNF, ONF, DKNF
Ans:-Yes, I know about the SPs and worked on the same during my training work. An SP is a group of SQL statements that can be used together to act. It accepts input parameters to be used with different scenarios. To ensure the integrity of a database, SPs are considered an added advantage.
Ans:-It consists of entities and relational objects. Entities can be understood by the collection of attributes in the database.
Ans:-In RDBMS, data can be abstracted at three different levels. They are given below -.
Physical Level -> Logical Level -> View 1, View 2 & View 3
The physical level is available at the bottom, giving you a detailed idea of the data storage. The Logical level at the next stage finds the logic among data tables and how to group similar data for easy access. At the top, there is a view level that gives information about the complete database and various views of a database.
Ans:-It is a stored procedure that acts as soon as some event occurs. Events are not called by the programmers but are invoked automatically as soon as edits are made systematically.

Ans:-A “view” is a subset of a database used to retrieve, delete, or combine the data. As soon as you edit a view, original data also changes in the table.
Ans:-For creating pointers to the data, indexes are used. They help in finding rows in a table quickly. Indexes can be defined for multiple columns together with a different name. They cannot be seen or accessed by users but helps in improving the database performance. For small tables, impacts can be negligible. In the case of complex data tables, the impact of indices is clearly visible.
Ans:-Yes, there are two methods for index storage in RDBMS. These are given below.
Clustered indexes can give information about the physical storage of the data and non-clustered indexes will give you an idea of logical ordering.
Ans:-It minimizes redundancy and integrity can be maintained. It maintains data consistency and allows data sharing to other databases. It follows a set of rules to satisfy storage standards and maintains security.
Ans:-A buffer manager transfers the data from third-party storage devices to the memory and puts some data into the cache for easy access.
Ans:-A key is a constraint added to a database for restricting the data access requirements. These are important for any database to maintain maximum data integrity.

Ans:- Integrity is determined by two rules.
Ans:- The number of tuples in a table at any one time is known as extension. This is time sensitive. Intention is a constant value that specifies the table's name, structure, and restrictions.
Ans:- It is a prototype, and its goal was to show that a Relational System can be built that can be used in a real-world setting to address real-world issues, with a performance at least equivalent to that of existing systems.
It has two subsystems. They are:
Ans:-
Ans:- Physical Data Independence defines that Physical data changes should not influence logical data. Whereas, logical data independence defines that modifications at the logical level should have an impact on the view level.

Ans:-
Data is processed by ETL on a separate server, whereas data is processed by ELT within the data warehouse. Raw data is not moved into the data warehouse via ETL; instead, raw data is sent directly to the data warehouse using ELT.
Ans:- The foundation of this concept is a collection of objects. Within an object, values are stored in instance variables. A collection of code that operates on an object is also known as an object. Certain sections of code are referred to as methods.

Ans:-
An entity type is a group of things with similar attributes.Whereas, an entity set is a collection of all entities in the database that belong to a specific entity type.
Ans:- The degree of a relation is defined as the number of attributes in the relation schema.
Ans:- Each record from a group of records can be specified and retrieved using Low Level or Procedural DML. Record-at-a-time retrieval is the name for this method.
Ans:- In a single DML statement, the High level or Non-procedural DML can define and retrieve several records. This type of record retrieval is known as Set-at-a-time or Set-oriented.
Learn how to handle relational databases and gain a thorough understanding of SQL queries by reading our comprehensive guide on SQL language.
Ans:- Relational algebra uses a procedural query language. It is made up of a collection of procedures that accept one or two relations as input and output a new one. Whereas, in relational calculus particularly optimized for relational databases.
Ans:- X Y indicates a functional dependency between two sets of attributes X and Y that are subsets of R, and it constrains the potential tuple that could result in a R relation state r.
The restriction is that if t1[X] = t2[X], then t1[Y] = t2[Y] for any two tuples t1 and t2 in r. This means that the value of the X component of a tuple determines the value of the Y component.
Ans:- In F, each right-hand side dependency has just one attribute.
We can't replace any dependency X A in F with a dependency Y A and still have a collection of dependencies identical to F. We can't remove any of F's dependencies while maintaining an identical set of dependencies.
Ans:- The constraint on any relation r of R is described by the multivalued dependence represented by X Y stated on relation schema R, where X and Y are both subsets of R: If two tuples t1 and t2 exist in r with the attributes t1[X] = t2[X], then t3 and t4 should likewise exist in r with the properties t1[X] = t2[X].
Ans:- It ensures that after decomposition, misleading tuple formation does not occur with relation schemas.

Ans:- It is based on the concept of total functional dependency. If removing any attribute A from X causes the dependency to break, it is called a full functional dependency.
Ans:-
A relation schema R is in BCNF if it is in 3NF and meets the extra restriction that X must be a candidate key for every FD X A. Read more about Normalization Forms.
Ans:- A relational model R is in 3NF if it is in 2NF and one of the following is true for every FD X A.
For more clarity, learn about Normalization Forms.
Ans:- The relation is considered to be in DKNF if all constraints and dependencies that should hold on the constraint can be enforced by merely imposing the domain constraint and key constraint on the relation.
Ans:-
A partial key is a set of qualities that may be used to distinguish weak entities belonging to the same owner.
An Alternate Key is a Candidate Key other than the Primary Key.

Ans:- A transparent DBMS keeps the data hidden from the user.
Ans:- The Hierarchical Schema utilizes a tree-like structure to arrange data. Here are the components of a hierarchical model:
Network Schema -
Network Schema is the hierarchical data model in its advanced form. It organizes data using directed graphs rather than a tree structure. A child can have more than one parent in this situation. It makes use of the two data structures known as Records and Sets.
The above figures can differentiate between hierarchical and network schema in DBMS.

Ans:- For each row of an outer query, these are subqueries that run. Each subquery is done just once for each row in the outer query.
Ans:- When the projections of the connected tables are ordered on the join columns, a merge join is used. Hash joins are slower and consume more memory than merge joins. A hash join is used when the projections of the connected tables are not already sorted on the join columns.
Ans:- Deadlock happens when two transactions wait for a resource that is locked or while another transaction is held. Deadlocks can be avoided by enabling all transactions to acquire all locks at the same time.
A super key is a single key or a set of keys that helps to identify a record in a table. Super keys can have one or more properties, even if all of them aren't required for the records to be identified. A candidate key is a subset of Super Key that can identify records in a database using one or more attributes.
Ans:-
The logical operation JOIN is used to get data from many tables. Only when there is a logical link between two tables can it be used. Moreover, the JOIN operator uses data from one table to extract data from another.

Below is the list of RDBMS interview questions and answers for experienced candidates.
Ans:- A database is a logical, organized, and consistent collection of data that can be easily accessed, managed, as well as managed. It is designed to let you create, insert and update the data efficiently. Database mostly contains objects and tables including records and fields.
Ans:- The abbreviation of Relational Database Management Systems, RDBMS helps in maintaining the data records and indices in tables. It is the form of DBMS that utilizes the structure to find and access data concerning the other pieces of data in the database. RDBMS is basically a system that allows you to perform numerous operations like update, insert, delete, manipulate, and administrator a relational database with minimal difficulties.

Ans:- Name: Every relation in a relational database should contain a unique name.
Attributes: Each column in a relation is called an attribute.
Tuples: Each and every row in a relation is called a tuple. It also presents a collection of attribute values.
Ans:-Here is the list of major advantages of RDBMS:
Ans:-Here is the list of different languages present in DBMS:
DDL: DDL stands for Data Definition Language, it contains commands required to define the database.
DML: Data Manipulation Language contains commands required to manipulate the data available in the database.
TCL: TCL or Transaction Control Language contains commands required to deal with the transaction of the database.
DCL: Standing for Data Control Language, DCL contains commands required to deal with the user permission and controls of the database.
Ans:-An index is a performance tuning method that allows the faster retrieval of records from the table. An Index helps in creating an entry for every value. There are three types of indexes:
Unique Index: Unique index is applied automatically when the primary key is defined. It does not let the field get duplicate values.
Clustered Index: Clustered Index reorders the physical order of the table and searches depending on the key values. This type of index can have just one clustered index.
NonClustered Index: It does not modify the physical order of the table and maintains the logical order of data. Each table can have 999 nonclustered indexes.
Ans:-Database partitioning is about partitioning tables, indexing into smaller pieces to maintain and access the data at a better level.
This process decreases the price of storing a huge amount of data and also improves performance and manageability.
Ans:-It is a set of information, explaining the content and structure of the tables and database objects. This information is used to control, manipulate and access the relationship between database elements.
Ans:-Database Trigger is a set of commands that get executed when an event such as Before Insert, After Insert, On Update, and On Delete of row occurs in a table.
Check out our guide on Brief Introduction To Different SQL Server Operators to understand the functioning of different SQL Operators.
Ans:- An entity can be taken as an object or thing with independent existence. An entity set is a collection of all entities within a database. Sometimes, an entity set does not have all the necessary attributes to define key constraints and other logical relationships then it is termed as the weak entity set. If an entity set has all necessary attributes to define the primary key and other constraints, it is termed as a strong entity set in that case.
Ans:-
Ans:-A wider range of relational operators that can be applied to a database can be given as: SQL Server Operators
SQL is a big domain, hence to boost your knowledge here’s a brief introduction to different SQL Server Operators
Ans:-
These four properties are considered highly important for any database. These properties make a database easy to access and use. It is possible to share data among tables conveniently. Also, it focuses on data accuracy and avoids redundancy.
Ans:-DBMS tells about data storage and data creation. RDBMS explains relations among tables and data values. DBMS operations can be used for a specific database, but RDBMS can work on multiple databases together.
Ans:-When designing a database, three types of relationships can be defined. These are:
Ans:-In the 4NF, it should satisfy the 3NF, and it should not contain two or more views about an entity. In the 5NF, we can reconstruct the information from small pieces of content so that they can be maintained with maximum consistency. Normalization Forms
Ans:-Whenever you are working on big data problems, it should be handled with care. Let us understand the concept with three technical terms Data Ingestion, Transformations, Storage & Analytics.
Data Ingestion uses technologies like Apache Kafka and streamlines the data across different targets gracefully. The second term is transformation, where data is reconstructed and transformed into a meaningful real-time solution.
The last term is Storage & analytics, where No SQL database can be utilized to manage all data issues and works on consistency problems eventually. Once you are done with it, these three features can give you more flexibility, high throughput, and low-latency benefits. In brief, we should replace the traditional batch-oriented approach with modern streaming solutions.

Ans:-A “view” is defined as a subset of a database or tables stored in it. It can be used to retrieve, delete, or combine the data. Each View can be taken as a separate table and accessed for the application. When changes are made to a specific VIEW, it will not impact others. This is the reason why VIEWS should be learned first to understand the concept of Data Independence in detail.

Ans:-
Check out our NoSQL Tutorial Guide for Beginners to learn the fundamentals of using NoSQL and implementing it in an application.
Ans:-There is a major difference between cluster and non-cluster indexes. Clustered indexes make changes in the table and reorder the way records are stored in the table. Nonclustered indexes also make changes in the data stored in the tablet but it makes a completely different object within the table.
Ans:- Atomicity: It is the condition where either all the actions of the transaction are performed or none. This means, if there is an incomplete transaction, the DBMS itself will undo the impacts made by the pending transactions.
Aggregation: It expresses the relationship with the entities’ collection and their relationship.
Ans:- There are three types of user-defined functions.
Ans:- OLTP is used to manage transaction-based applications, it is used for data entry, data retrieval, and data processing. It makes data management efficient. The purpose of the OLTP system is to serve real-time transactions.
Ans:- Here is the list of three different data models that are available for database systems:
Ans:- Union: It is used to combine the outputs of two tables, eliminating the duplicate rows from the tables.
Minus: It is used to return rows from the first query but not from the second query. When you match records of the first and the second query and other rows, you will be able to see the query as a result set.
Intersect: It is used to return rows that are returned by both queries.
Ans:- Character-manipulation functions effectively extract, edit, format, or modify in some way a character string.
Ans:- Different types of SQL:
Trim: The SQL trim helps to get rid of the leading and trailing characters from a character string.
Translate: Translate replaces a sequence of characters in a string with another sequence of characters. It replaces one character at a time.
Ans:- The combination of fields that uniquely specify a row is called the primary key. It is a unique key that has an implicit NOT NULL constraint. It means, its values cannot be NULL.
The form of the candidate key is referred to as a composite key, it is a set of columns that uniquely figure out every brown in the tablet.
Also, know why Oracle is the perfect choice for most organizations, holding an Oracle Database Certification will help you validate your proficiency & grow your career in this field.
Ans:- Cardinality is defined as its equivalence class under equinumerosity. In simple words, it is described as a fundamental relationship between two entities or objects. There are three types of cardinalities- one-to-one, one-to-many, and many-to-many.
Ans:- It is basically the representation of the data structure in the form of a tree for external memory that reads and writes large blocks of data. It is generally used in databases and file systems where all the insertions, deletions, sorting, etc., are done in logarithmic time.
Ans:- The work of a DML compiler is to convert the DML statements into a query language that the query evaluation engineer can understand and process. The DML Compiler is needed since the DML is the family of syntax elements that are quite similar to the other programming language that needs compilation. That is why it is important to compile the code in a language that the query evaluation engine can understand.
Ans:-
Online transaction processing is referred to as OLTP, whereas online analytical processing is referred to as OLAP. OLTP stands for online database modification, while OLAP stands for online database query response.
Ans:- Null values can be replaced with default values using the NVL function. If the first parameter is null, the function returns the value of the second parameter. If the first parameter is anything other than null, it is ignored. This function is only accessible in Oracle; SQL and MySQL are not supported.
Check out our Advanced SQL Server Interview Questions and Answers to prepare well for your upcoming interviews.
Ans:-
The rank of each row within your sorted partition is determined by the RANK() function in the result set. The DENSE RANK() method assigns a unique rank to each row inside a partition based on the provided column value, with no gaps.
Ans:-
NoSQL databases are designed for certain data models, such as graphs, documents, key-pairs, and wide-column tables. Unlike relational databases, they feature flexible schemas. NoSQL databases are popular because of their ease of use, functionality, and scalability. They can be expanded horizontally across hundreds or thousands of servers, unlike SQL databases.

Ans:-
Locks are commonly used to ensure that only one user/session can modify a certain piece of data.
There are two types of locks:
Ans:-
Data Warehousing is the process of gathering data from several sources (extracting, converting, and loading) and storing it in a single database. The data warehouse can be thought of as a central repository into which data flows from transactional systems and other relational databases.

Ans:- Lock escalation occurs when a system combines numerous locks into a single higher-level lock usually to free up resources taken up by a large number of fine-grained locks.
Heading on to your next SQL interview? Check out our top Oracle DBA Interview Questions and Answers.
Ans:- Lock contention arises when numerous operations request an exclusive lock on the same table. Operations must wait in a queue in this situation. If you have ongoing lock contention, you'll need to further divide those data blocks so that multiple processes can gain exclusive lock at the same time.
Ans:-
Hashing is a search method. A method of mapping keys to values. Hash functions take a string of characters and turn it into a fixed-length value that may be used as an index to find the original element.
Advantages of hashing
Ans:-
Q100) What do you understand by the term ‘Write Ahead Log’ in DBMS?
Ans:- The Write Ahead Log is a database system approach for maintaining atomicity and durability of writes. The WAL's main principle is that before we make any actual changes to the database state, we must first log the whole set of activities we want to be atomic and durable to storage.
Check out our guide on Delete vs Truncate SQL Server and understand the differences on how to implement these SQL Commands.
Ans:- A table or column may be given an ALIAS name. To identify the table or column, use this alias name in the WHERE clause.
Ans:- To assess mathematical calculations and return single values, we employ aggregate functions. From a table's columns, one can compute this. Based on the input value, scalar functions return a single value.
Ans:- Phantom deadlock detection refers to the situation when a deadlock does not actually exist, but is still detected by deadlock detection techniques as a result of a delay in the propagation of local information.
Ans:- The inconsistent state is before the checkpoint, which is the point at which all the logs are permanently recorded on the storage drive. The system can restart from the checkpoint in the event of crashes, saving time and effort.
Ans:- In order to manage and access the data at a finer level, database partitioning involves dividing tables and indexes into smaller sections.
Ans:-
Ans:- A stored procedure is a group of pre-compiled SQL queries that, when run, represent a program that accepts input, processes it, and outputs the results.
Ans:- The data can be recovered using the COMMIT and ROLLBACK statements after the "DELETE" action has been run.
Following the completion of the "TRUNCATE" operation, the statements "COMMIT" and "ROLLBACK" cannot be used to recover the deleted data.
To remove a table or key, such as the primary key or foreign key, use the 'DROP' command.
Ans:- A software testing technique called "black box testing" involves testing the functionality of software programs without being aware of the internal code structure, implementation specifics, or internal paths. Black Box Testing is a sort of software testing that is only motivated by software requirements and specifications and focuses on the input and output of software applications. An alternative term for it is behavioral testing.
Ans:- Relational databases interview questions frequently include Oracle because it is the most widely used RDBMS. Its fully scalable relational database architecture accounts for its popularity. Oracle database products provide customers with versions that are both high-performing and economical.
The Oracle database provides a built-in network component that enables network communications. As a result, it has become the preferred option for leading international corporations that manage and process data across wide and local area networks.
Check out our guide on SQL Operators to understand the use of SQL EXISTS and SQL NOT EXISTS operators.
Ans:- A stored process that continuously invokes itself until it encounters a boundary condition Programmers can reuse the same code multiple times thanks to this recursive function or process.
Ans:- The following list of collation sensitivity variations.
Ans:- Local variables are those that can be utilized or already exist within a function. They cannot be referred to or used since the other functions are unaware of them. Every time that function is invoked, variables can be created.
The variables that can be used or are present throughout the entire program are known as global variables. No two variables that have been declared globally may be utilized in functions. When that function is called repeatedly, global variables cannot be generated.
Ans:- SQL constraints are used to limit the table's data type options. It can be supplied when the table statement is being created or modified. The list of restrictions includes UNIQUE PRIMARY KEY FOREIGN KEY, NOT NULL CHECK BY DEFAULT
Ans:- View is a fictitious table that is kept active so that users can view their data even if it doesn't actually exist.
Ans:- 1NF is known as the First Normal Form.
The domain of an attribute should only have atomic values in this kind of normalization, which is the simplest. The purpose of this is to eliminate any duplicate columns from the table.
Ans:- This is used in conjunction with SQL queries to retrieve specified data based on user requirements and SQL-defined constraints. This is particularly useful for selecting specific records from the entire set of records.
