Create and Use a Query, Form, Report & Printing a document from access


A query is a database object that retrieves specific data from one or more tables and then, in a single datasheet, displays only the data you specified. Because the word query means to ask a question, you can think of a query as a question formed in a manner that access can interpret.



A form is an Access object with which you can enter data, edit data, or display data from a table or a query. Thinks of a form as a window through which you and others can view and work with the data.


A database table is similar in structure to a worksheet, in that data is stored in rows and columns. As a result, it is usually easy to import a worksheet into a database table. The main difference between storing your data in a worksheet and storing it in a database is in how the data is organized. Simply importing your entire worksheet as a new table in a database will not solve the problems associated with organizing and updating your data, particularly if your worksheet contains redundant data. To solve those problems, you must split the spreadsheet data into separate tables, each one containing related data. For more information about how to arrange the data in your tables, see the article Database design basics.

Access features the Table Analyzer Wizard, which can help you to complete this process. After importing your data into a table, the wizard helps you to split the table into separate tables, each of which contains data that is not duplicated in any of the other tables. The wizard also creates the necessary relationships between the tables. For more information about relationships, see the section Relationships in a database in this article.
