Encrypting with a Password
Access 2010 combines two tools for database security: database passwords and encryption
A password is a collection of characters that a user types to gain access to a file.
A password protected database cannot be opened unless users provide the correct password.

Encrypting with a Password (continued)
When you encrypt a database with a password, data within the database is made unreadable.

Opening an Encrypted Database
When opening an encrypted database, you will be asked for a password.
After you enter the password, the database should open so that you can view and make changes to the database objects.
Until the correct password is entered, no objects in the database can be viewed.

Making a Backup Copy of a Database
A backup is a duplicate copy of your database created by using the Back Up Database option when you save the file.
By creating a backup, the database can be restored in the event of a data loss.
A good rule of thumb is to schedule a database backup on a regular basis.– For example, at the end of each day or at the end
of each week

Documenting the Database Design
The database design refers to the objects in the database, such as tables, queries, forms, reports, macros, and the relationship between these objects.
The Database Documenter produces a report of selected objects or every object in a database.– You can document the properties of these objects
and the relationships of objects that you select.
