The database administrator's job was to oversee any and all database-oriented tasks. This included database design and implementation, installation, upgrade, SQL analysis and advice for application developers.. The DBA was also responsible for back-up and recovery, which required many complex utility programs that run in a specified order. This was a time-consuming energy draining task. (Fosdick 1995) Databases are currently in the process of integration.
In the age of computer automation and electronic commerce, many businesses have become dependent upon scalable and error proof software platforms. The ongoing support of these systems by the software manufacturer is crucial for the business owner, and the software's longevity. Software Maintenance is a detailed process for weighing suggested program additions, making program updates, supporting user-related questions, and fixing latent errors. This process is both heavily time and resource consuming for software firms. This is why it is important for all software firms to have a strong and well-organized software maintenance plan, in which any changes to a given product are, to be followed.
For example we need to access our Database to update some information from it or just to extract it. Most of the businesses need a DB. They need to retrieve data in its complete form for further analysis or different objectives. Databases are needed to store our data being ready and available when required. b) DBMS (Crucial Concept): The DBMS would be responsible for all database activities (storage, retrieval, indexing, etc) and also be responsible for keeping a detailed description of the data being held.
Since there are so many database management systems are available, so it is important to ensure that they communicate with each other. This is because, most database software comes with an Open Database Connectivity (ODBC) driver which allows the database to incorporate with other databases. A DBMS perform several important functions that guarantee the integrity and consistency of the data in the database. Most of these functions are transparent to end users, and most can be achieved only through the use of a DBMS. They including the data dictionary management, data store management, security management and also backup and recovery management.
Databases are made to operate all type of informations by storing, retrieving and managing that informations. Databases are made so that user can interact with databases itself. DBMS is usually responsible for mainting all the data in a system and if that data lost then DBMS will restore the data itself. Databases are used for business operations but increasing number of database systems are usually made for more stable interaction with the users.

Analysis and Research for a data warehouse system Data warehousing is a difficult system and has to have the capability deliver quality data. An operational database is one which is used by organizations to run its day to day database activities. They are designed to handle rapid transaction processes with systematically updates. Velocity is important to operational databases. They are most commonly operated by office staff, and are on the order of megabytes of data to gigabytes.
Database designers might be employed by the company itself, or they might be employed by third parties and responsible for developing databases for many types of organizations.

In many organizations the data administration, which is operated by the database administrator, involves many duties such as what follows in this quote.
The primary responsibility for computer information technology specialists is selecting hardware and software products depended on what the kind of technology need in the business organizations, installing software, and maintaining software and hardware if the business organizations need it. In addition, try to find technical solutions for any problem. The last responsibility for computer information technology specialists has created some software, but simpler than computer science specialists, creating Web pages, and do the periodic maintenance of databases. There are two important tracks for computer information technology and labor market needs. It is a software engineering and network.
