 Scarching is finding records in a report through reference to a unique field of every document/statistics referred to as the key. The key is a unique filed used to pick out sure record in a record. If a record is to be inserted right into a report, it have to take delivery of a

Facts Processing

Records Processing is the evaluation and organisation of information with the aid of the repeated use

Of one or extra pc programs. Statistics processing is used significantly in commercial enterprise, engineering, and technological know-how and to an increasing extent in almost all are as wherein computer systems are used. Organizations use statistics processing for such : tasks as payroll education, accounting, report, keeping, stock manage, sales analysis, and the processing of financial institution and credit score card account statements.

In database processing, a automated database is used as the imperative supply of efference facts for the computations. Transaction processing refers to interaction among  computers in which one computer initiates a transaction and another laptop presents the first with the data or computation required for that feature.



Most cutting-edge statistics processing makes use of one or extra databases at one or greater crucial sites. Transaction processing is used to get entry to and update the databases whilst customers need to at once view or upload records; other statistics processing applications are used at normal intervals to offer precis record of pastime and database reputation.
