Basics of Database Is Not Rocket Science! Learn Them Now!

A database is a store of large quantity and classes of data, we recognise data immediately and effortlessly from it. 

A database is essentially composed of columns and rows. Each column has a title representing what sort of data accessible in that column. The column is known as a field. Some adjacent columns make a row. Each row is called a record. A large amount of data can be organised and used according to the requirements creating different types of tables in the database.

Storing Data in a database file in the computer, originated in the 60s. At that time, a database was a data table. But now, the concept of the database has achieved multi-dimensions, under a database, single or multiple data table queries, form, report and other files subsist. That implies a database consists of single or multiple files.

Some mentionable database programs are Microsoft Access, FoxPro, foxbase, Oracle, Fourth dimension, Paradox etc. Characteristics of a database program:

• A condition in the field can mark the limit of the data entry at the time of entering the data in a database program to avoid any mistake. It is called the input validation code.
• Based on the particular field, two or more tables can exchange data. 
• The index is used to find out data from the database. 
• Based on a particular field, we can build up a relation between multiple tables for data exchange.
• Link can be built up between files. If the similar data available in another file updates automatically, when any of the files updates.  
• If we want, we can change the record structure.
