Less This article shows you how to bring data from an Access desktop database into an Access web app, so you can share it with friends and colleagues in an internet browser. Not using an Access web app? Are you looking for information on how to import data into an Access desktop database? In that case, see Import or link to data in another Access database. As an alternative, consider using Microsoft PowerApps to build no-code business solutions for the web and mobile devices.

See the relationships between tables Overview A database is a collection of information that is related to a particular subject or purpose, such as tracking customer orders or maintaining a music collection. For example, suppose the phone numbers of your suppliers are stored in various locations: in a card file containing supplier phone numbers, in product information files in a file cabinet, and in a spreadsheet containing order information.

In a well-designed Access database, the phone number is stored just once, so you only have to update that information in one place. Access database files You can use Access to manage all of your information in one file. Within an Access database file, you can use: Tables to store your data. Queries to find and retrieve just the data that you want.

Forms to view, add, and update data in tables. Reports to analyze or print data in a specific layout. Store data once in one table, but view it from multiple locations. Retrieve data by using a query. View or enter data by using a form. Display or print data by using a report. For example, you may have one Access database that contains nothing but tables, and another Access database that contains links to those tables, as well as queries, forms, and reports that are based on the linked tables.

In most cases, it does not matter whether a table is a linked table or actually stored in the database. Tables and relationships To store your data, you create one table for each type of information that you track. Types of information might include customer information, products, and order details. To bring the data from multiple tables together in a query, form, or report, you define relationships between the tables.

You can use lookup fields to create relationships in a web database or web app. Customer information that once existed in a mailing list now resides in the Customers table. Order information that once existed in a spreadsheet now resides in the Orders table. You can also use a query to update or delete multiple records at the same time and to perform predefined or custom calculations on your data. The Customers table has information about customers. The Orders table has information about customer orders.

The query returns only orders that were required in April, and only for customers who are based in London. Forms You can use a form to easily view, enter, and change data one row at a time. You can also use a form to perform other actions, such as sending data to another application. Forms typically contain controls that are linked to underlying fields in tables.

When you open a form, Access retrieves the data from one or more of those tables, and then displays the data in the layout that you chose when you created the form.

You can create a form by using one of the Form commands on the Ribbon, the Form Wizard, or create a form yourself in Design view. A table displays many records at the same time, but you may have to scroll horizontally to see all of the data in a single record. A form focuses on one record at a time, and it can display fields from more than one table.

It can also display pictures and other objects. A form can contain a button that you click to print a report, open other objects, or otherwise automate tasks.

Reports You can use a report to quickly analyze your data or to present it a certain way in print or in other formats. For example, you may send a colleague a report that groups data and calculates totals. Or, you may create a report with address data formatted for printing mailing labels. Use a report to create mailing labels. Use a report to show totals in a chart. Use a report to display calculated totals. Now that you know about the basic structure of Access databases, read on to learn how to use the built-in tools to explore a particular Access database.

See details about the objects in a database One of the best ways to learn about a particular database is by using the Database Documenter. You use the Database Documenter to build a report containing detailed information about the objects in a database. You first choose which objects will be detailed in the report.

When you run the Database Documenter, its report contains all of the data about the database objects that you selected. Open the database that you want to document. In the Documenter dialog box, click the tab that represents the type of database object that you want to document. To create a report on all of the objects in a database, click the All Object Types tab.

Select one or more of the objects listed on the tab. To select all of the objects on a tab, click Select All. Click OK. The Database Documenter creates a report that contains detailed data for each selected object, and then opens the report in Print Preview. For example, if you run the Database Documenter against a data entry form, the report created by the Documenter lists the properties for the form as a whole, the properties for each of the sections in the form, and the properties for any buttons, labels, text boxes, and other controls on the form, plus any code modules and user permissions that are associated with the form.

To print the report, on the Print Preview tab, in the Print group, click Print. This information is useful because data types and input masks can affect your ability to find data and run update queries. For example, suppose that you want to use an update query to update particular fields in one table by copying data in similar fields from another table.

Open the database that you want to analyze. In the Navigation Pane, right-click the table that you want to explore, and then click Design View on the shortcut menu.

As needed, note the name of each table field and the data type assigned to each field. The data type assigned to a field can limit the size and type of data that users can enter in a field. For example, users may be limited to 20 characters in a text field, and cannot enter text data in a field set to the Number data type. To determine whether a field is a lookup field, click the Lookup tab in the lower section of the table design grid, under Field Properties.

A lookup field displays one set of values one or more fields, such as a first and last name , but usually stores a different set of values one field, such as a numeric ID. When you use a lookup field in expressions or in find and replace operations, you use the stored value, not the displayed value.

Becoming familiar with the stored and displayed values of a lookup field is the best way to make sure that an expression or a find and replace operation that uses the lookup field works the way that you expect. The following illustration shows a typical lookup field. Remember that the settings that you see in the Row Source property of the field will vary. The lookup field shown here uses a query to retrieve data from another table.

You may also see another type of lookup field, called a value list, that uses a hard-coded list of choices. This figure shows a typical value list.

By default, value lists use the Text data type. The best way to find lookup and value lists is by displaying the Lookup tab, and then clicking the entries in the Data Type column for each field in the table. For more information about creating lookup fields and value lists, see the links in the See Also section.

Top of Page See the relationships between tables To see a graphical representation of the tables in a database, the fields in each table, and the relationships between those tables, use the Relationships object tab. On the Database Tools tab, in the Relationships group, click Relationships. The Relationships object tab appears and shows you the relationships between all of the tables in the open database.

Akinolrajas The SqlDataSource control supports the same operations, but the approach is different, and this tutorial shows how to configure the SqlDataSource to insert, update, and delete data. Starting with Delphi dbExpress 4 generation a tracing driver is included as well which allows for logging all statements sent to the database. Create radial and rectangular zones and track intersections, enters, and exits with callback events. In previous tutorials we learned how the ObjectDataSource control allowed for inserting, updating, and deleting of data.
