Applies To: Access 2007 This article explains how to update existing data. Microsoft Office Access 2007 provides a number of tools for updating existing records, including datasheets, forms, queries, find-and-replace, and the new Data Collection feature.
As you proceed, remember that updating data is not the same process as entering new data. For information about entering new data in a database, see the article. In this article How database design affects updating Read this section if you are new to Access or unfamiliar with the concepts behind relational databases. Large updates become much easier to perform when you understand some of the basic principles of database design. An Access database is not a file in the same sense as a Microsoft Office Word 2007 document or a Microsoft Office PowerPoint 2007 slide deck. Instead, a typical Access database is a a collection of tables, plus a set of objects built around those tables — forms, reports, queries, and so on.
In addition, those objects must adhere to a set of design principles or the database will either work poorly or fail altogether. In turn, those design principles affect how you enter data. Remember these facts about database objects and design as you proceed. • With a few exceptions (such as a type of list called a value list), Access stores all data in one or more tables. The number of tables depends on the design and complexity of the database. Although you may view or update the data in a form, a report, or in the results returned by a query, Access stores the data only in tables. • Each table should store data for a single issue, category, or purpose.

For example, a table of business contact information should not contain sales information. If it does, finding the correct information can become difficult, if not impossible. • Each of the fields in a table should accept only one type of data. For example, you should not store notes in a field set to accept numbers.
If you try to enter text in such a field, Access displays an error message. • With one exception, the fields in a record should accept only one value.
For example, a properly designed database will prevent you from entering more than one address in an address field. This is in contrast to Microsoft Office Excel 2007, which, by default, allows you to enter any number of names, addresses, or images in a single cell unless you set that cell to accept limited types of data. However, Office Access 2007 also provides a new feature called a multivalued field. You use multivalued fields to attach multiple pieces of data to a single record, and to create lists that accept multiple values. For example, you can attach a text file, a Office PowerPoint 2007 slide deck, and any number of images to a record in your database. You can also create a list of names and select as many of those names as needed.
The use of multivalued fields may seem to break the rules of database design because you can store more than one piece of data per table field, but it actually doesn't, because Access enforces the rules 'behind the scenes,' by storing the data in special, hidden tables.

How data types affect updating Read this section if you are new to Access or unfamiliar with the concepts behind relational databases. Large updates become much easier to perform when you understand some of the basic principles of database design. When you design a database table, you select a data type for each of the fields in that table, a process that helps ensure more accurate data entry. For example, suppose you specify the Number data type for a field because you need to calculate sales figures.
