The Concept of a Database

 In general we might say that all the files that make up the data processing system of a company form their database.

However, the term database is now used in a much broader and more comprehensive sense. To appreciate this let us contrast a conventional data processing system and a database system.

A conventional data processing system consists of one or more separate files for each application; in a database system a single large collection of data serves all applications.

If we were to survey the software market today, we would find a large number of database systems available.



Database= databank = banco de dados

Files= arquivos

Make up= formam

Broader= larger, wider = mais amplo

Sense= sentido, significado

To survey= to examine = examiner, pesquisar

Software market= Mercado de software, isto é, de programas
