Understanding Databases and Database Management Systems

Nearly all business applications need to store large volumes of data, organized in a format retrieval. This is’accomplished with a .da.tabasemanagement system (DBMS), a mechanism for manipulating tabular data with high-level commands. The.database management system hides low-level details, such as how data are stored in a database, and frees the programmer to concentrate on managing…
