When working with an Access database you're working with many Access objects simultaneously. Learn to manage them here.
It's helpful to think of your database as a large binder or folder in which you store your data. The data itself is contained in database objects. Access 2010 treats each of these objects as separate documents, which means you will have to open and save them individually in order to work with them.
You may have noticed that this lesson contains no instructions for saving a database. This is because you cannot save an entire database at once. Rather, you must individually save the objects contained within the database.
By default, the most recently opened object will display in the main window as the current object. To view another open object, click its tab in the Document Tabs bar.
As in other Microsoft Office programs, you will be prompted to save any unsaved work when you attempt to close your database. However, it is a good idea to save your work as you go along. Saving your work often is the best way to ensure you don't lose any information if your computer crashes.
To save an existing object, select save in Backstage View, or simply click the Save command in the Quick Access toolbar.
You can also close an object by right-clicking its tab on the Document Tabs bar. A drop-down menu will appear. Select Close to close that object, or Close All to close all open objects.
