SQL Server CDC

  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 streamli...

  Let us start with the basics of SQL Server CDC ( Change Data Capture). Its goal is to record all changes made in the data, like delete, update, or insert, after which, their details are provided to users in a simple relational format. The changes that are captured and noted in the source tables are replicated under column information in the target tables. However, unlimited access is not given to the changes recorded by SQL Server CDC , as it is a matter of ensuring data safety and security. Permission to access the changes is strictly controlled by the table-valued function. Functions of SQL Server Change Data Capture The benefit of SQL Server CDC is that it automatically updates users with changes made to the database. These changes can be applied to specific tables or applications whenever needed. One example of the optimized use of SQL Server CDC is the Extract, Transform, and Load application. It extracts data from a source table, transforms it to match the data structure o...

  Change Data Capture is a software pattern used for tracking and capturing changes made to a database. Types of changes include insert, delete, and update, which are stored in downstream systems.   Oracle launched its Oracle Change Data Capture product with its 9i version. Its core function was to track and capture deletes, updates, and inserts made to user tables in an Oracle database to be used in ETL applications. These changes were then processed, formatted, and moved to other storage repositories such as target databases or data warehouses. The function of Oracle Change Data Capture is to track and record all changes made in a database. These are used by businesses for analytics and to make fast and optimized operational decisions. Oracle CDC also boosts database performance and increases the speed of data warehousing operations. What sets Oracle Change Data Capture apart from others in this niche is that it helps to replicate databases without adversely impacting t...
