Database synchronization is the process of establishing data consistency between two or more databases, automatically copying changes back and forth. Harmonization of the data over time should be performed continuously. Pulling out data from source (master) database to destination (slave) is the most trivial case..
Also, how do I sync two different databases?
Create the example databases on your SQL Server. Specify the data sources you want to compare. Review the results and select the objects you want to synchronize.
Create and run a synchronization script.
- Set up the databases.
- Set up the comparison.
- Select objects to synchronize.
- Synchronize the databases.
Additionally, what is database synchronization SQL Server? SQL Data Sync is a service that allows synchronizing data across multiple Azure SQL databases and on-premises SQL Server databases. This agent communicates between Hub and on-premises SQL Server database.
One may also ask, how does database replication work?
Data Replication in DBMS. It is simply copying data from a database from one server to another server so that all the users can share the same data without any inconsistency. The result is a distributed database in which users can access data relevant to their tasks without interfering with the work of others.
What is sync process?
Process Synchronization means sharing system resources by processes in a such a way that, Concurrent access to shared data is handled thereby minimizing the chance of inconsistent data. Process Synchronization was introduced to handle problems that arose while multiple process executions.

Why do databases fail?
Hardware failures may include memory errors, disk crashes, bad disk sectors, and disk full of errors among others. Hardware failures can also be attributed to design errors, inadequate or poor quality control during fabrication, overloading (use of under-capacity components) and wear out of mechanical parts.What is database mirroring and replication?

Damaged or missing data can be restored to a single row, without the need for a full database recovery.What is SQL Server replication?
SQL Server replication is a technology for copying and distributing data and database objects from one database to another and then synchronizing between databases to maintain consistency and integrity of the data. In most cases, replication is a process of reproducing the data at the desired targets.What is Azure Data Sync?
Azure SQL Data Sync allows you to synchronize data between Azure SQL Database and any other SQL endpoints unidirectionally or bidirectionally. It enables hybrid SQL deployment and allows local data access from both Azure and on-premises application.What happens if I turn off Sync?
