Database Systems

  • The database system consists of logically related data stored in a single logical data repository

    • However, the data might be physically distributed among multiple storage facilities

  • The database’s DBMS eliminates most of the file system’s data inconsistency, data anomaly, data dependence, and structural dependence problems

  • The current generation of DBMS software stores data structures, relationships between those structures, and access paths to those structures

  • The current generation also defines, stores, and manages all access paths and components
