Data Migration: Database Migration MS SQL to Oracle DB

Data Migration is an important function anyone working with a database should be able to carry out.

There are several tools available to perform database and data migration. In this course we will be using a free powerful tool by Oracle called Oracle SQL Developer to migrate a third party database from Microsoft SQL Server into Oracle.

Database migration involves several steps specified below:

Setting up a Migration Repository : The Migrations Repository is a database schema that stores the meta data collected and transformed in the migration process.

Configuring the Third Party Database Connection : You need to configure a database connection for the database which you would like to migrate. There are two steps to this process:Download JDBC driver and Connecting to Third
Party Database.

Capturing Source Database :This step is used to capture a snapshot of the current state of your third–party database and is necessary to provide SQL Developer with a point in time view of your database. Once this step is complete, the Migration wizard works on the meta–data stored in its repository, instead of issuing queries against your live database.

Convert Captured Model to Oracle : The next step in the migration process is to convert the captured model of the database to an Oracle–specific model.
