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,
- Controlling Details Redundancy
- Data Consistency
- Data Sharing
- Data Integration
- Data Security
- Development of an Application
- Creating Forms
- Control over Concurrency
- Backup and Recover Options
- Data Independency
- Advanced Capabilities
- 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.
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 Administration allows discussing of data easier among authorized customers of the said data management program.
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 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.
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.
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.
A database management program provides functions like reporting data through the internet and obtaining data files online.
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
