Reports provide information found in the database in a useful way. In this they are similar to queries. Reports are generated from the database's tables or queries. They can contain all of the fields of the table or query or just a selected group of fields. Reports can be static or dynamic. Static reports contain the data in the selected fields at the time the report was created. Dynamic reports can be updated to show the latest data.
||Dynamic reports update only the data that is changed or added to a table or query. It does not show any modifications made to a table or query. For example, open the fuel economy query you just created. For the "End-Reading".”Odometer – Fuel.”Odometer” column, change the number 1 to the number 3 after creating the report below. The report will be identical before and after you make the change.
For example, a report on vacation expenses divided into categories should probably be a static report because it is based upon specific data that does not change. However, a report on the fuel data should probably be a dynamic report, because this report depends upon data that does change.
||All reports are based upon a single table or query. So you need first to decide what fields you want to use in the report. If you want to use fields from different tables, you must first combine these fields in a single query. Then you can create a report on this query.
An example of this caution is creating a report on vacation expenses. Fuel costs are one part of that report as are meal costs. These values are contained in fields of two different tables: Vacations and Fuel. So this report requires creating a query.
