Microsoft Access is a Database Management System software, used to easily collect data, offline or online.
You can use it to collect data from people, including their contacts, any website link, or any attachment, in order to save a database from a working group, a school class, or your own contacts. This data will compose a Table, which is filled manually, or through online Forms, where other people can import his own data directly on your database.
If you need, export your data by creating a Report, and use inner functions by using automated Macros and Modules. Databases can be exported directly via xml or pdf extensions, or on Excel.
Microsoft Access is indeed one of the most suggested products to help you at managing your own databases.
