An Overview Of Moving Databases From Oracle to SQL Server

 Let us start with why you should migrate databases from Oracle to SQL Server. 

Benefits of Oracle to SQL Server database migration  

  • Most important is the cost factor since using Oracle can be very expensive, especially if all the features like Oracle Enterprise Manager or Oracle Data Guard are used. SQL Server, on the other hand, offers all advanced database engine features like Analysis Services or Reporting Services in one license cost. 
  • The SQL Server can better handle large volumes of data processing loads. 
  • Oracle users get locked into a single vendor with high licensing costs. However, Microsoft SQL Server offers several versions, with users having the flexibility to choose one as per the features required and pay accordingly. Among the versions are the Enterprise and the Standard models. 
  • SQL Server keeps costs down through merging databases, visualizing servers, allotting resources optimally, and compressing data. This leads to more streamlined and seamless data policies. 
  • Exclusive reporting systems can be created by utilizing the unique automated business intelligence attributes of SQL Server, thereby reducing the dependence on IT and database administrators. 

All these benefits make moving databases from Oracle to SQL Server a very attractive proposition for businesses. 

How to Migrate Databases From Oracle To SQL Server 

There are two ways to migrate databases from Oracle to SQL Server. 

One-Shot Method

Here, the entire database is migrated at a time. All systems must be shut down during the process, as otherwise, all transactions that occur after the last backup will not be moved to the new target database. Before this migration method is adopted, several test executions need to be undertaken to make sure that there is no glitch on migration day. 

Phased Method

There are two steps here. First, the focus is on Oracle to SQL Server of data that does not change or rarely does so. Once this is completed, migration of data is done at preset intervals of any incremental data that comes up after the last run.

SQL Server Change Data Capture – A Comprehensive Overview

Image
  Microsoft launched its SQL Server CDC product in 2005 with several cutting-edge and technologically advanced features, such as “after update”, “after insert”, and “after delete” abilities. Since this technology was very complex and not received well by DBAs, Microsoft released a revised and more advanced version of the SQL Server CDC in 2008, which became very popular and is still in use today. The Concept of SQL Server Change Data Capture SQL Server CDC captures and records changes made in the source database, such as “Insert”, “Update”, or “Delete”. These can be accessed by any user seamlessly, with all details available in an easy-to-understand relational format. CDC provides all the information required for capturing the changes to an intended target. The data for modified and changed rows is available in CDC. The changes made are stored in tables and are reflected in the structure of the tracked source tables. For data security, access to the table-valued functions of ...

What is SQL Server Change Data Capture – Evolution and Function

Image
  The goal of SQL Server CDC is to capture any changes made in a source database and present them to users in a simple relational format. Types of changes include insert, update, and delete to the database. All inputs required to capture these changes to the target, such as column information and metadata, are available for the modified and changed rows. After the changes are made and noted in the tables at source, they are replicated in the column information of the target tables. As a matter of database safety and security, access to the changes is monitored closely. Development of SQL Server CDC It was in 2005 that Microsoft launched SQL Server CDC with “after update”, “after insert”, and “after delete” features. However, DBAs found its working quite complex. Based on this feedback, Microsoft introduced a revised version in 2008, which was very user-friendly, well-received, and is still in use today. In this version, database administrators can capture and store changes ma...
