If you want to grab a job for a database testing profile then this blog post will surely help you. Every database testing has a different meaning, so its scope and job profile is also different. Here, we are going to provide you with a list of database testing interview questions that will help you in grasping the job quickly and provide success in the interview. The blog will cover all of the possible database testing interview questions for the post or profile of database testing.
Here, we have divided the questions into two sections, one is for fresher and the other is for experienced candidates. These backend testing interview questions will help you in getting familiar with which type of questions are frequently asked by interviewers and help you in getting your dream job.
Are you a fresher in Database testing? Then these are the database interview questions for you:
1). Define database testing
2). What are the different types of testing?
3). Explain the structural database testing?
4). Explain the Schema Testing?
5). Explain the Table Testing?
6). Explain Functional or Procedural Testing?
7). Explain the Trigger Testing?
8). Explain the Database Server Testing?
9). Define the database indexing in brief?
10). Enlist the different types of indexes.
Database testing is the process to check all triggers, schema, functions, and procedures. Moreover, it is linked with testing of data consistency and integrity.
Mainly testing is the following types:
When a database structure is tested that involves tables, schema, function, database server, and triggers, then it is called testing of the database structure.
The schema testing is being done in this way so that the name of frontend and backend schemas should be matched. The checkpoints involved in this testing are the validation of schema format, as sometimes the requirement of schema structure may differ from the requirement of the business process and the front-end application structure. Here, unmapped tables, columns, and views are also verified.
Table testing involves the testing of table and column names. Here front-end columns are mapped, while back-end names may remain the same. Data type and size of the column must remain the same and as per the business requirement and should be mapped to the front-end application. Here, in this testing, constraint testing is also required that may include testing of the foreign key, primary key, and other conditions related to table or data. In table testing, cluster or non-cluster table indexing is also being tested.
Below-listed things and steps are involved in the procedure or Function Testing:
For this testing, rules are the same for the procedure and function testing. Here it has been checked whether the trigger is being executed as per specific event requirement or on the occurrence of a particular event or not.
Here database server configuration is being checked. Execution processing capacity, storage capacity, and RAM should be as per user requirements.
The index is created in the table column that may perform query execution faster and even it can be executed frequently as well.
Indexes are of following types
Are you an experienced professional in Database? Then here are some Database interview questions for you:
Database testing process of data loading involves the following steps:
We can use insert, select, delete, update or create table commands including alter table and drop table commands to manipulate the table or data.
Here, a large amount of data is being tested for load in minimum time. The system response is being tested, when load testing is being done. In case if the load exceeds the user process, then it is known as load or stress testing. The testing examples may include multiple application execution on a single computer or downloading datasets.
If the user tests data from the backend side, at the time when new data has been added, deleted or updated from the front end side.
Only one clustered index can be created on a single table.
Users can check the number of database objects, that have been created in two ways that are listed below:
Database testing is performed for a number of reasons. As many times it may require testing data integrity, consistency and validation because the backend system is responsible to access and store the data for a variety of reasons. A few of such reasons are listed below:

Below-listed steps are included in the Database Testing:

SQL or structured query language has the following types of statements:
After getting functional requirements, the user must understand table structure, Joins, Cursors, Stored procedure, parameters, and triggers. Then you can write a test case along with different values as the inputs to these objects.
In this way, you can get the database testing done in just a few steps and then you can apply for various profiles of database testing. As per the job profile and requirement, you can apply for the job and for that just prepare for the exam. In fact, you can also read many other questions for the interview and get ready for that. There are plenty of resources that can be helpful.
The profile may also require some knowledge of SQL programming and therefore it may be good for you if you will have some information about the profile and concepts. Here, we have listed some of the questions, but they are not limited. There can be many other ones.
