Data Replication and Integration

Replication is the process of duplicating and maintaining database objects in a range of databases that taken together make up a distributed database system. Once you make a change at one site, it is captured and stored locally and then forwarded and applied at every remote location. Oracle replication is not a separate server but a fully integrated feature of the Oracle server.

The Internet has enabled extensive worldwide collaboration and information sharing of databases by extending the reach of database applications throughout communities and organizations. In the modern digital business environment, it is always business on the go, from any location, and round the clock. Without continuous access to data, customers will turn away, revenue will be lost, and penalties by regulatory authorities might be imposed. The Oracle database provides Oracle real time replication and integration features that are critical to the operation of any enterprise, regardless of the size and scale.

There are two sides to this replication process.

Oracle Golden Gate is a software package that enables replication of data between Oracle and non-Oracle data storages. It is a part of Oracle Fusion Middleware and is the primary data replication tool from Oracle. 

Another is Oracle Streams that is a built-in facet of the Oracle database and is an integration and data replication feature. It offers flexible infrastructure that caters to a host of information sharing needs. The benefit here is that Oracle Streams enables the transmission of data, transactions, and events in a data stream either within a database or from one database to another.

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 The need then is to replace outdated and inefficient legacy processes through agile and new techniques.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
