Before going into the process of migrating Oracle Database to Microsoft SQL Server, it is necessary to understand the two separately.

The Oracle database feature used for enterprise grid computing helps in creating modular servers and storage. The storage mechanism is enabled by creating logical and physical structures while the database can be accessed only through the client-side program. The server-side memory structure is known as the SGA (System Global Area). It holds cache information related to SQL commands, data buffers, user-specific information, and log buffers.

Now, before coming to Oracle to SQL Server database migration, what is Microsoft SQL Server It is a SQL Server Database Engine that controls data storage, security, and processing. The relational engine processes queries and commands while the storage engine manages database files, tables, pages, indexes, data buffers, and transactions. The data is generally connected without redundancy, therefore making for greater data integrity.

The Oracle to SQL Server database migration is as follows.

· Creating a new SSMA project and after that setting project conversion, migration, and type mapping options.

· Connecting to the Oracle database server

· Connecting to an instance of SQL Server

· Mapping Oracle database schemas to SQL Server database schemas.

· Converting Oracle database schemas into SQL Server schemas

· Loading the converted database objects into SQL Server. This can be done either by saving a script and running it in SQL Server or synchronizing the database objects.

· Migrating data Oracle to SQL Server

· Updating database applications.

This process of Oracle to SQL Server has other uses too. It can be done not only for successfully migrating objects and data from Oracle databases to SQL server but also Azure SQL database and Azure Synapse Analytics.
