Oracle Database Administration 2 Training

Oracle DBA classes in Pune teaches you the all the basics of DBA.

What is Data Administration?

Data management is a procedure whereby data resources are arranged and supervised in the field of pc and information technology. This is done through a Database Management System(DBMS).

What are the advantages of Data Administration?

Data Administration through using DBMS has a number of functions. These are as follows,

  1. Controlling Details Redundancy
  2. Data Consistency
  3. Data Sharing
  4. Data Integration
  5. Data Security
  6. Development of an Application
  7. Creating Forms
  8. Control over Concurrency
  9. Backup and Recover Options
  10. Data Independency
  11. Advanced Capabilities
  12. Report Writers

Controlling Data Redundancy

When working in a standard program (non-database), several data files of the same data can get developed at many places. However Database Administration guarantees that all the data files are integrated into only one databases. This makes sure that the same data files are not copied more than once.

Data Consistency

Checking Data Redundancy also guarantees Data Reliability. If an item only appears one, any upgrade needed on its value is performed only once and the upgrade is made available to all customers.

Data Sharing

Data Administration allows discussing of data easier among authorized customers of the said data management program.

Data Integration

In a knowledge source management program, data on a knowledge base is stored in the form of platforms. A procedure has several platforms which can allow relationships to be drawn and retrieve data.

Data Security

Data protection includes protecting the details of a program from non-authorised customers. Data management guarantees that this protection is maintained.

Development of an Application

The databases management program provides resources that can be used to build up a software applications. Hence, this reduces cost and time needed to build up a software.

Creating Forms

Forms are a user-friendly, simple way of entering data that can be recovered and used later. One of the important functions of a knowledge source management product is types. It allows for creation of types and administering it can ensure that the data entered is supervised regularly.

Control over Concurrency

In a standard program, there is a good venture of data being overwritten if two customers are obtaining the same data at the same time. However, a knowledge source management program guarantees that such concurrency is kept in check and prevents such glitches from affecting data.

Backup and Restoration Options

In a knowledge source management program, sub-systems like back-up and recovery are automatically provided to guard data from being lost. In a standard computer-file program this is a highly time intensive procedure (especially if the details is large) where the consumer has to constantly create back-up techniques to guard data.

Data Independence

In a knowledge base management program, the database and program are separated-a procedure that is referred to as data freedom. The advantage of this is that databases can be customized without changing the application itself.

Advanced Capabilities

A database management program provides functions like reporting data through the internet and obtaining data files online.

Report Writers

A databases management program allows for reports to be developed quickly through providing review writing resources. These can be edited and customized quickly. It is stored along with the database and behaves like a constituent of the software.

What is the role and responsibility of a Data Administrator?

Database, irrespective of its dimension, requires at least of Database Manager, also known as DBA. An Oracle Database may have many customers and hence, can be very huge in dimension. It is therefore clear that databases management is often not job for only one person to handle but includes work that need to be shared among a group of responsible DBAs.

According to a manual on Oracle Database Administration, a knowledge source administrator’s obligations can cover the following obligations,

Installing and upgrading the Oracle Database server and program tools

Allocating program space for storage and preparing future space for storage requirements for the details source system

Creating main databases space for storage structures (tablespaces) after program designers have developed an application

Creating main objects (tables, views, indexes) once program designers have developed an application

Modifying the details source structure, as necessary, from information given by program developers

Enrolling customers and also program security

Ensuring conformity with Oracle license agreements

Controlling and tracking customer access to the database

Monitoring and optimizing the performance of the database

Planning for back-up and recovery of data base information

Maintaining stored data on tape

Backing up and restoring the database
