Because my Article about how to teach Mircosoft Access in Oracle transactions seems to be very popular, I decided to post an English version of it. In future I will concentrate to write in English. Microsoft Access is a widely used product in a number of companies in all industries. This is because the Microsoft Office package is widely used, and access solution 'so ubiquitous. Unfortunately, this solution has its drawbacks. These are noticeable when man realizes an Access front end for a database connection. One of these drawbacks is the lack of ability to implement transactions or to use stored procedures and table functions. About the Access interface alone this is not possible. While there is an SQL pass-through to execute DBMS-proprietary SQL queries, but these are often only possible static and need to be adjusted. Visual Basic for Applications (VBA briefly) here can provide some relief. So it is possible, for example, assign the button controls of an Access form VBA mac...

The first thing I wanted to do was coding an java app to connect to Oracle database and fire lots of queries into the DBMS. As you maybe know, a JDBC driver is needed for this intention. You can download it at Oracle Software Downloads ( http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-112010-090769.html ). And as you also know, you need to add in Eclipse IDE as a JAR file to your project.

It's ca...
