19 Sep 2019

In Oracle, you can specify virtual columns in a table definition. Oracle Database doesn’t store these virtual columns on the disk. Instead, the values of Oracle virtual columns are always calculated automatically. Oracle uses a set of expressions or functions to derive the values in the virtual column based on the values of other columns. SQL Server does have computed columns on a table that provides support similar to Oracle’s virtual columns. By default, SQL Server does not store these columns in the table unless you mark them as persisted. Making the calculated column persisted is an optimization in SQL Server that Oracle doesn...

Fast data comparison with Database Compare Suite
11 Sep 2019

We continue our blog post series that cover the key Database Compare Suite features. In our previous blog posts, we talked about validating data migration and discovering exact data differences in selected tables. Now, we want to talk about comparing huge data assets. For example, when it comes to comparing tables with millions/billions of rows, the operations may last for minutes and even hours. Of course, this is unacceptable, especially when we talk about the downtime of the production environment. So, we want to show how you can use Database Compare Suite to quickly verify migration of extremely huge tables. Check out our video to see how...

How to establish a database connection after converting Oracle Forms to the web app?
04 Sep 2019

DB Best has successfully completed several Oracle Forms modernization projects, making our customers happy with the new web architecture of their solutions. However, the first question that we regularly hear from our customers sounds as follows. How will the converted web application interact with the database? The problem When an Oracle Forms application communicates with the database server, it acts as a client by querying the database server for requested data. Oracle Forms applications manage the database connection internally. In addition to that, Oracle Forms execute queries and run SQL statements internally. To address this issue, we c...
