Yet, Access can search for this information at the blink of an eye.
If you search for specific types of data on a regular basis, you probably don’t want to keep telling Access what to search for over and over again. To simplify this, you can create a query. A query lets you define specific ways to search your data and save those parameters so you can retrieve data instantly the next time you need it.
Besides searching through data, Access can also sort data. Sorting can be as simple as organizing names alphabetically, or it can be more complicated, such as sorting names according to zip code, annual salary, and alphabetically by last name. Sorting simply rearranges your data so you can study it from a new point of view.
By searching, sorting, and querying your data, you can extract useful information about your data.
