A database is a collection of data that is organized so that its contents can easily be accessed, managed and updated. Databases contain records of files, such as sales transactions, product catalogs and inventories and customer profiles. Who creates these systems? It is the job of a database developer.
A database developer writes and modifies databases. Data in a database can be reorganized, dispersed, and accessed in a number of ways. Databases are important to companies and organizations, because they contain records or files, such as sales transactions, product catalogs and inventories, and customer profiles.
Database developers create management systems to provide effective and efficient access to information stored in databases. They provide expertise and guidance in the design, implementation and maintenance of database management systems. Database developers control the design and use of the database and they also determine the way the filing systems will be organized and accessed. An important part of this work involves implementing and controlling security procedures to protect the database from accidental or intentional damage or loss.
