17. Query-by-Example (QBE)
Visual approach for accessing information in a database through use of query templates.
Example values are entered into template to represent what access to database is to achieve, such as the answer to a query.
Originally developed by IBM in 1970s [Zloof] and has proved so popular that QBE (or similar) is now provided by most DBMSs.
When user constructs a QBE - in background, DBMS creates an equivalent SQL statement.

37. Connect MS-Access & Oracle
Do a search and find odbcad32.exe (ODBC Data Source program) or
Control Panel -> Administrative Tools -> Data Sources (ODBC)
Then follow the instructions at
Click on the System DSN panel above (second one from the left) and the add button on the right of A Create New Data Source window appears as shown in Next slide.

38. Select Driver
Select the Microsoft ODBC for Oracle driver and click the Finish button

39. Define Server
A Microsoft ODBC for Oracle Setup window will appear as shown in Figure 3 below (from . For Data Source Name you can choose any name (OracleAccess, for example). For Server Name you choose the Oracle instance (or the service name in a multi-user environment). The other two parameters are optional. User Name is the Oracle user, but you should leave it blank, that way you can login as any user. Click okay and click okay again to save the ODBC Data source and exit.

40. Get External Data
Launch MS-Access and select File Menu -> Get External Data -> Link (if you select import, you are simply copying the oracle tables to MS-Access)

41. Select File type

42. Select Data Source
When the Select DataSource window appears (Figure 6), select the Machine Data Source tab and then select the Data Source you created.

43. Select PK
When you click the okay button, you will get a login window. Type in your Oracle user name and Password (Server name is the database instance name and should already come typed for you). You then should get a screen with tables which you can select. Select the tables you want link to next slide. Click OK button

44. Link Tables
When you click the okay button (in previous slide), you will get a login window. Type in your Oracle user name and Password (Server name is the database instance name and should already come typed for you). You then should get a screen with tables which you can select. Select the tables you want link to (slide below).

45. Select PK
After you select the tables, make sure you also select the field you want to define as a primary key. Otherwise you will only be able to view data (and not modify).

46. See Linked Tables
You will then be able to access the oracle tables as if they were MS-Access tables. However, since you chose the Link Option (not the import), you are actually modifying the Oracle Database.

47. Import/Export
