Three Main Advantages of Computer Database
The three main advantages of a computer database over a paper database are:
Massive Storage:
The largest computer database can fit on a hard disk, but a paper database might take a roomful of file cabinets.
Fast Retrieval:
Searching for a single name in a computer database is fast and easy. Doing the same thing in a paper database is difficult, error prone, and nearly impossible with a large database.
Reporting:
A report can help you make sense out of your data, such as showing a list of customers who earn a certain amount of money and live in a specific area. Trying to find this information in a paper database is time consuming and error prone.
