Database Replication and Software features

Database replication is the activity of continual electronic copying of data from one database in a computer or server to another database in a separate location. This recurrent copying enables all users to have the same level of information at all times without interfering in each other’s work. The whole process is carried out through specific software which supports data security, disaster resilience, and business continuity.

Data replication software helps to rapidly create a data replica at a location that is independent of the source of the data. It provides centralized management of replication policy across diverse data sources and targets. This is quite different from conventional data backups which retain one unchanged copy over an extended period. Replication, on the other hand, continually updates data and ensures consistency for end-users accessing multiple data stores in the normal course of business.


There are several other features of data replication software. Zero-downtime data migration and multi-site replication for business continuity in the event of a site disaster is one such critical feature. Hence data replication is essential for long-term data retention and archiving. The software also provides real-time transactional data delivery and integration into data lakes to support big data initiatives.

Data replication software is not free and is available on a paid subscription basis. The cost depends on the number of data sources to be replicated or the volume of data. It also varies with data destination and whether data storage is monitored by the replication service provider.

An Introduction to Database Replication

Image
The volumes of data generated by businesses today are massive. IT departments are expected to ensure that this data is online and accessible indefinitely, thereby putting immense pressure on the data management process. The need then is to replace outdated and inefficient legacy processes through agile and new techniques. SQL Server Replication is the most used technique to achieve this goal. But first – what is SQL Server Replication? It is a technology for copying and distributing objects from one database to another after which the databases are synchronized to maintain integrity and consistency of data. Database replication SQL server is used for continuous copying and synchronizing data or scheduled to run at intervals that are determined from time to time. The data synchronization can be carried out in several ways as per the replication techniques deployed. Here are some of the techniques used for data replication. Snapshot replication – In this process, a “snapshot” is tak

A Guide to Changed Data Capture

Image
Changes in a database like inserts and deletes are very common across organizations and everybody would expectedly want to retain a history of all modifications made. Hence, it is necessary to have the required tools to ensure that it is made possible. This is where Oracle CDC (Changed Data Capture) has a very critical role to play. It can process and capture changes made at the source of data and apply them throughout the organization. CDC aims to ensure data synchronicity by reducing the resources required for ETL (Extract, Transform, Load) processes and is possible because CDC deals with data changes only. The main benefit of limiting the source data flow to changed data only is in the area of data synchronization and replication and is critical for setting up event-oriented architecture for integration. In such a case, data changes are made by applications during a business process. All such changes are captured by the Oracle Data Integrator and changed to events that are circu

Steps to Replicate Oracle Database to Snowflake

Image
Oracle database has a unique networking stack feature that facilitates easy integration of applications, thereby ensuring data integrity and reliability. Despite this versatility, businesses opt for Oracle to Snowflake replication of databases. Why is this so? Snowflake, a cloud-based data warehousing solution has many benefits. It has separate compute and storage facilities and users can scale up and down, paying only for resources used. Further, multiple users can work on multiple workloads without facing any drop in performance.  Here are a few steps to replicate data Oracle to Snowflake . •Mining data from Oracle to a CSV file – For extracting data, Oracle Database Server is used to query and redirect the result to a CSV file. For mining incremental data, that is data relating to changed records only after the last replication, a SQL Plus tool has to be run in appropriate conditions. •Converting and formatting data – Before replication, it is critical to ensure that the data is
