What is Oracle DBA?

A Database is the structured collection of organized information that can be accessed, modified, or analyzed efficiently. If we talk about simple software applications like Word, Excel, or Spreadsheets then they could not handle voluminous data efficiently. Here, we need a secure storage system where data can be stored or retrieved quickly whenever required.

To make this approach feasible, Oracle discovered a Relational Database Management system (RDBMS) to store, retrieve or modify information more efficiently and securely. The RDBMS system delivers high performance and maximized data concurrency that boosts up the overall productivity of the multi-user database environment. It can be termed as RDMS or simple Oracle Databases. Oracle DBAs (Database Administrators) use specialized software programs to store or organize information in a mashed-up way.

Oracle Database Tutorial: Oracle DBA Physical Files

Let us have a quick look at the physical files that are used by Oracle Database to store voluminous data.

  • Data Files: These are the special database files that contain data required to initiate the database engine.
  • Parameter Files: These are the files that reside on the machine only and the Oracle database server executes on parameter files only.
  • Redo Log Files: These log files contain modified information or the changes we made to the databases.
  • Control Files: This is the metadata or storehouse for the database used by the Oracle engine.

Oracle Database Tutorial: Basic Terminologies in Oracle Database Administration

In this section, we will discuss all important terms that are necessary to understand before you start working on the Oracle database. This section covers almost all terms and parameters that are used frequently in Oracle Databases.

  • Shared Memory: This is sometimes referred to as the Random-Access Memory (RAM) that stores a handful of entries to facilitate the application access. There are two types of memory management techniques in Oracle Database Administration. These are two types of shared memory
    • Manual Memory Management
    • Auto Memory Management
  • System Support Infrastructure: These are the mix of foreground and background processes that facilitate application interaction with the databases. One system support process starts automatically as soon as one Oracle instance is initiated. Each process plays an important role in managing the interaction between an application and the data.
  • Operating System Files: These are the suite of files that play a significant role individually as soon as the database runs.
  • Instance: This is an important part of memory structure that can be defined as the background process to retrieve data from the database.
  • Process: Process is a running instance that can be named as Job or task as well in the Oracle database administration. These are divided into two major categories i.e. Oracle Processes or User Processes.
  • Buffer Cache: This is a small storehouse that contains frequently used or customized data. This cache is popular to optimize the overall performance of memory and they are connected to the database as well for quick access.
  • Shared Pool: This pool contains data that needs to be shared with the users.
  • Large Pool: As the name suggests, this is an optimal place to store the large processes with robust options like Data Recovery and backups.
  • Redo Log Buffer: This is a backup storehouse that contains the modified data and helps to recover instances or processes. This is an important part of Oracle database 12C architecture that works amazingly in case of system failure.
  • Locks: Locks are required to control the simultaneous

Oracle Database Tutorial: Database Objects Learning

Objects in the Oracle database are used to perform a variety of functions. Here, we will discuss the common objects that can be used in our day-to-day environment while working with Oracle databases.

1). Tables – Organized Data Storage

Tables are the common objects that are used as an integral part of the database. Once a table is created, data should be stored by following the basic rules like data types, values, etc. Table compliance of all-important rules is always easy to access and modify with simple SQL commands.

2). Views – Limited access to Data

If the database administrator wants to limit the access of data then the view concept comes into the picture. Here, different views of data can be defined based on users and Company requirements.

Take an example, where you want to share only a limited amount of information with another organization then you need to mask the rest of the information with proper SQL commands.

You are free to list the important modules only that you want to make visible in front of others. The modules that are not listed will not display and it will be hidden from the users. Views were introduced to enforce a flavor of security and it is frequently used worldwide.

3). Synonyms - Referring Objects from Other Databases

It allows users to refer to objects that are stored somewhere else in the same or other databases. These objects are handy objects that can be used with alternative names in the table and you just need to set a pointer to the real table.

This is a memory management technique where the same objects can be reused and it optimizes the overall storage space for database objects. The concept has been used by database programmers for decades to increase the throughput of the application code.

4). Stored Objects – Reusability of Code

These objects promote the encapsulation of code that could run either implicitly or explicitly to perform some predetermined task. The best part is that stored objects can be reused again and again whenever some action is required. It ensures consistent performance and secure processing together. They can be further divided into procedures, functions, and packages to declare constants, variables, and cursors for exceptional handling.
