Reasons for Choice of Software
I have chosen Microsoft Access for my project 1B which is about car database.
Spreadsheets can be used as a database. In Excel you can add a filter that will help you to sort data more quickly.
The biggest advantage of using a database instead of a spreadsheet is the ability to search and sort information contained in the database. Microsfot Access provides means to perform not only the simple search needed but also complicated searches based on an unlimited number of search criteria.
For example I created simple and complex Queries to search information from my car database.
