Why Do Organizations Prefer Oracle Database Replication

When you are storing data in several locations so that the current database version can be accessed from any remote point, the activity is known as database replication. Data is copied from one server to another for sharing across regions.

A critical benefit of data replication is disaster recovery where an outage in one location automatically triggers servers in other locations so that work is not interrupted. Further, when a data backup is placed close to the user, there is an improvement in database performance and a reduction in network loads.

For decades now, the Oracle database management system has been very popular and one of the most optimized ways for organizations to increase database efficiencies has been Oracle replication.

Oracle replication provides users access to information whenever needed through the creation of synchronized multiple copies of an Oracle database. These copies can be used for testing, business reporting, backups for disaster recovery, and distributed data processing. The replication software also provides data in real time. This enables businesses to enhance the performance of critical applications and databases and provide data even remotely for analytics and business insights.

There are two modes in Oracle replication.

Synchronous replication: Data is replicated to both the primary and secondary areas and hence, the data replicated is identical and updated at both the source and the target. This mode is ideal for disaster recovery of data or if a project requires zero data loss.  

Asynchronous replication: In this mode of Oracle replication, there is a certain lag and delay when copying data as it is first written to the primary site and later committed to a secondary source at pre-set intervals.

Using the Database Replication Tool

Image
Data Replication is the process where data is copied from a central database to one or several other databases. The publisher is the source database from where data is to be moved and the subscriber is the intended target database where data is replicated. The process of data movement is optimized only when the best database replication tool is used, giving users access to the same set of data. A database replication tool has several functions. Among the most advanced and cutting-edge capabilities are data security, disaster data recovery and resilience, and business continuity. The tool automatically manages the replication process across diverse sources and targets. However, the difference between data replication and backup is that in replication, all changes made after data replication in the source database are continually updated in the target system. Currently, data replication tools provide transactional data delivery in real-time and integrate into data lakes. A top-end datab...

The Various Facets of SQL Migration

Image
SQL is short for structured  Query Language and is used to search, insert, update, and delete database records. It is the standard platform for interacting with Relational Database and other operations that can be carried out including optimizing and maintaining the databases. In the past and before SQL migration was  introduced, almost all applications functioned in a standalone environment with a single server responding to multi-user activity from various locations. This led to multiple complications like performance problems, availability problems, and maintenance issues. Now, SQL migration can  take care of these issues and maintain database copies at multiple locations.  SQL migration is a very effective process that ensures organizations can increase both the performance of SQL databases and the availability of information. It helps businesses to combine and move data into data warehouses, copy and distribute data across multiple database servers in remote ...

Making Amazon S3 a Target for DMS Amazon Web Service

Image
Before diving into the various aspects of AWS DMS CDC S3 a quick look at each component separately is in order. The Amazon Web Service Database Migration Service or AWS DMS is a cloud-based platform that facilitates easy migration of data warehouses, relational databases, NoSQL databases, on-premises systems to the cloud, and one cloud provider to another. CDC or Change Data Capture is the process of recording modifications made in the latest production data or metadata which is then stored in a separate data repository replication software. Amazon S3 or Simple Storage Service is ideal for users, who, among other things want to work with limited storage operations and quickly scale up to tens of terabytes of data if required. The advantage of AWS DMS CDC S3 is that the replication activity can be done both within and outside the region with S3 having the capability to go through billions of objects of Batch Operations. Users can migrate data using AWS DMS CDC to S3 from any su...
