synchronize database

Oracle DBMS_COMPARISON package overview

Posted by on September 24th, 2010

During replicating data in one or another way, it happens that synchronized objects may differ. This situation may take place in the following cases:

  • If changes made in one of copied databases were not captured
  • The changes were captured but not forwarded
  • The changed were forwarded but not applied due to some reasons

It should be admitted that full or partial synchronization may be required due to some other reasons, not related to replication. But the question is how to synchronize database objects?

Synchronizing data between a company database and a data warehouse

Posted by on April 15th, 2010

Recently we’ve received a question from one of our customers asking how to synchronize data between companies servers and a data warehouse server. Let’s see how easy it can be done with the help of  dbForge Data Compare for SQL Server, a professional tool for data comparison and synchronization.

What we have:

We have two companies ( they use ERP software), each having their own SQL Server database with one table. The companies tables with their customers’ data are saved in the data warehouse as follows:

  • The SQL table for company1 is Company1$Customer.
  • The SQL table for company2 is Company2$Customer.

What we need:

We need to create a data warehouse with all information stored in one set of SQL tables. For example, the created data warehouse should contain a Customer table that contains all records of Company1$Customer and Company2$Customer.  This table should contain an extra field with a company name to make the records unique. We need to synchronize only changed records.

How to complete the task:

Easy ways to quickly exclude objects from schema synchronization

Posted by on August 4th, 2009

Many users of dbForge Schema Compare for SQL Server ask us how to exclude all the objects or a group of objects at once from synchronization. It is not a problem.

Pay attention to the document with comparison results. In the middle of the grid, just between Source Objects and Target Objects columns, you can see two columns – one with check boxes (they will help you exclude the objects from the synchronization or include them), the other – with operations which will be applied to the Target objects during the synchronization.
