A relational database is a collection of data stored in various tables that is 'related' to data in other tables
It is a tool which can store, manage and disseminate information of various kinds. The information from the separate tables can be used, retrieved and displayed together.

• Forms are used for data entry and to view data
• Queries are used to retrieve information
Reports display information in a format determined during the design process

 

 

 

 

 

Spreadsheet versus Database
A spreadsheet stores data in rows and columns - it is a 'flat' storage system. It is the computer equivalent of a paper ledger. Each row is one record. As more and more data is tracked for one record, columns are added. Microsoft Excel is a spreadsheet program.

Relational databases are more versatile than spreadsheets. Because data is stored and updated in only one place, a database can eliminate duplications and inconsistent data. Data is easy to retrieve. Microsoft Access is a relational database program. Mathematical calculations can be performed in Access, and data can be imported from and exported to Excel and integrated with other Microsoft Office programs.
