A Database Management Systems (DBMSs) is a
compu
ter software deliberated to store large
ter software deliberated to store large collection of data that manages databases.
In the earliest days of computers, data have been a major application focus when comes to storing and manipulating large collection of data. The general purpose of DBMS in the early 1960s was to integrated data store. In the late 1960s, IBM developed the Information Management System (IMS). IMS created the "basis for an alternative data representation framework called the hierarchical data model." (pg.6, Ramakrishnan, Gehrke)
In 1970, the Relational Data Model (RDM) introduced by IBM. It glowed the rapid development of several DBMS and it dominated its position until 1980s. In the late 1980s and the 1990s, many advance changes made to database systems. "Considerable research was carried out into more powerful query language and richer data models, with emphasis placed on supporting complex analysis of data from all parts of enterprise. The data is stored in a relational DBMS and the application layer can be customized to different companies, leading to lower overall costs for the companies, compared to the cost of building the application layer from scratch." (pg.7,Ramakrishnan, Gehrke)
Lately, the DBMS introduced to the Internet because database gave widespread access to a browser to use the data. "Today the field is being driven by exciting visions such as multimedia database, interactive video, streaming data, digital libraries, a host of scientific projects etc. DBMS represents one of the largest and most vigorous market segments." (pg.7, Ramakrishnan, Gehrke)

FILE SYSTEM VS DBMS
* Data stored in devices (ex: disk, tape)
* Write special programs to answere each question a user may want to ask about the data
* Make sure the data is restored by the new changes or system crashes
1. Designed to make the hard tasks easier
2. Storing data in a DBMS rather than as a collection of operating systems files
3. Manage the data efficient and dynamic
