Evolution of Database Management Systems

As computers emerged as potentially useful machines in the 1960s, the term of database was created to describe what the computers would be good for, namely the storage and presentation of vast amounts of information. The early database system models followed a navigational usability, with operators only being able to move from record to record within the database programs. However, the understanding of how a relational model would work in the early 1970s led to much improvement in database programs.

The relational model quickly became the normal operating procedure for a database management system and program developers looked for elegant solutions to linking the content of each record. The answer was found in using an SQL server for the purpose. The term of SQL server means that a database computer is used for storage and is capable of making searches using a structured query language. In addition to finding data, the language can also be used to update or delete individual records. This language spawned many different database system companies, such as Oracle, DB2, and the Microsoft SQL server.

The industry for database management system programs has grown by leaps and bounds. Insiders use the DBMS acronym to describe the industry and the extent of the applications is still being discovered. The relational model of the database programs are being used for a variety of purposes, including being able to search email records and even in common search engines like Google or Yahoo. These searching entities look at content rather than the title of a record and return matches that bear the closest resemblance to the search terms. Many of these database programs are automatically updated to see new content as it arrives. The database management system field continues to expand with new improvements appearing on a regular basis.
