Program Plan Intro

Database:

Database is an organized data collection, and every data present is related to each other in some way. It contains the occurrences of data to satisfy the needs of the user in an organization.

Program Explanation

Database Connectivity and uses:

  • Database connectivity includes the application programs used for communicating with storage device like database repository.
  • It has the information of both software application and hardware database and thereby, it is also known as database middleware.
  • The data repository which is a data management application is used for storing the applications, data and information required.
  • The data repository can be located anywhere in the database in the form of relational database, hierarchical database, spreadsheet or text.
  • It has the ability of creating database structures on storage requirements.
  • It has complex structures which can be accessed by multi-users.
  • It stores the data definitions and Metadata in a directory or dictionary and the changes made to that definitions and Metadata will be automatically updated in directory or dictionary.
  • It has the ability of performing data backup and recovery which assures the data safety.
  • It represents the usability of data and the data is affected only in allowed ways during the database transaction.
  • Data independence is the ability of accessing the programs which are independent of storage characteristics of data.
  • In multiprogramming, the users are allowed to complete the tasks simultaneously without effecting the other transactions.
