  • DBMS systems provide mechanisms to represent concurrent access of data to multiple users.
    Controls concurrency
  • If redundancy is controlled in centralized system, there is lesser chance that the data is inconsistent.
    Avoids inconsistency.
  • If it is too functional and complex, it means that it has a huge amount of data stored.
    Size
  • A computerized database is compact, flexible, and fast. It can store thousands of data without occupying too much space.
    Computerized Database
  • Some integrity constraints are enforced on the database making the integrity of always accurate.
    Enforcements Integrity
  • A standard can be enforced easily at various levels since the standardized data is very helpful during migration or interchanging of data.
    Enforces standards
  • It is commonly used for recordkeeping in schools and offices and also at home.
    Database
  • A DBMS must provide facilities for recovering from hardware or software failure.
    Provides backup and recovery
  • When multiple users share database, it is likely that every user has different access type
    Restricts Unauthorized access
  • It comes in varied forms like words, number, or symbol data also relates to transactions, facts and events.
    Data
  • Aside from high cost building it, DBMS also incurs recurrent annual maintenance.
    Cost
  • It is contains one specific category of data. For example, Information on a students goes to simple database as information on his or her school grades goes into a different database.
    Simple Database
  • In a centralized system, applications may be developed without having to create any new stored files since the files are shared by the users
    Shares data
  • The centralized system is able to represent the complex data and interfile
    Develops data model
  • It is collections of different sets of data related to each other.
