Unlike synchronization, which is a one-time process that brings the schema and data of two databases in sync, replication is a process that continuously automatically reproduces data between two databases although schema updates are also possible.
Replication may either be done asynchronously, so that a permanent connection between the two databases is not required, or during non-peak hours, when there is little traffic on the database server, for instance, during the late-night hours. In either case the result is a distributed database in which users can access data relevant to their tasks without interfering with the work of others.
The implementation of database replication for the purpose of eliminating data ambiguity or inconsistency among users is known as normalization.
In the Database Synchronization Strategies whitepaper, we explored some strategies for synchronizing two databases that are of the same and of dissimilar type, using the Navicat Premium Database Management System. In a distributed database management system DDBMS changes, additions, and deletions performed on the data at one location are automatically reflected in the data stored at all the other locations. Doing so ensures that every user accesses the same data set as all the other users.
A scenario where Heterogeneous replication would be required would be where one or more external business partners employ a different database type than our own. Automated regular data replication between the two environments is often an integral part of such an arrangement.
Automation is the execution of a process at one or more regular intervals, beginning and ending at a specific date and time, much like Windows Task Scheduler. In addition to replication, it can be utilized for a variety of jobs, including backups, queries, and reports. It was developed by Mike Hillyer, a former member of the MySQL AB documentation team, and was created specifically for the purpose of providing a standard schema for use in books, tutorials, articles, and the like.
For instructions on setting up the Sakila database using Navicat, see the Generating Reports on MySQL Data article on databasejournal. As described above, Snapshot Replication puts two databases in sync by copying data from one database to another on the same or on a different server. It is the simplest of the three types. A data synchronization profile must first be created in order to automate it as a replication process. The steps to achieve both Homogenous and Heterogeneous synchronization in Navicat Premium 12 were described in the Database Synchronization Strategies whitepaper.
After comparing data, the window shows the number of records that will be inserted, updated or deleted in the target tables. There are also checkboxes to deselect the tables or the actions you do not wish to apply to the target.
Values that differ between source and target are highlighted. As in the top pane, you can uncheck the records that you do not want to apply to the target. The kind of differences to show may be selected from a dropdown list. Here are the possible options:. This screen, like all the previous ones, contains a Save Profile button that allows you to save your settings for future use.
This particular screen also has a button for saving the Deployment Script. You may still Recompare the two databases, or proceed to Execute the deployment script. There is a checkbox to Continue on error so that deployment does not halt upon encountering an error. As the script executes, you may view its progress in the Message Log. It displays both the number of records processed and completed percentage:.
After closing the dialog, we can confirm that the sakila2 database tables now contain data:. In the General tab of the Task Schedule dialog, you may provide a description for the task as well as provide several options for its execution.
You may also choose to run the task as Hidden as well as configure it to run on a specific operating system. The Triggers tab lists the task’s schedule.
Tasks may be configured to run on a variety of schedules, including One Time, Daily, Weekly, Monthly, and according to just about any permutation of each.
The same task may run according to numerous schedules. For instance, we could schedule our database synchronization task to run every first of the month as well as on every second Sunday:.
As the name suggests, Merging Replication consists of combining data from two or more databases into a single database. The Merging Replication job will require us to create and save two Data Synchronization profiles: one for each source database. Batch jobs may be triggered by the source databases or by the target, as we did in the previous section on Snapshot Replication.
However, it is usually easiest to trigger batch jobs from the target database since they will all reside on the same server. We’ll do that here as well. In Merged Replication, only the merged database contains all of the latest data. Each source database contains only the baseline data, plus whatever was inserted since it was first populated. In Transactional Replication, users receive full initial copies of the database and then receive periodic updates as data changes so that all databases are working with the same dataset.
Keeping multiple databases in synch makes this the most complex replication type. With Transactional replication, the number of required Data Synchronization Jobs increases substantially because data must be replicated across all of the user databases.
For example, say that we had three databases called sakila, sakila2, and sakila3. We could merge and propagate the full dataset across all of the user databases using a total of six Data Synchronization Jobs: three to merge the user databases, and another three to update them with the merged dataset. To allow sufficient time for the data merging to complete, it is best to split the jobs into two parts where the first merges the data and the second updates the user databases with the full dataset after a specified delay.
Here is what the Automation Job that propagates the merged dataset to the user databases might look like:. Running this job two hours after the first should provide plenty of time for the merging to complete. Hence, if the first job was scheduled to run at midnight, we would set this job to start at 2 Am:.
Used in conjunction with its Synchronization tool, it allows DBAs to automate various types of replication to run on a predefined schedule. For more information about Navicat Premium 12, visit the product page. Products Support Partners About Us.
About Us. Navicat Blog. Automate Database Replication with Navicat Premium January 9, by Robert Gravelle Unlike synchronization, which is a one-time process that brings the schema and data of two databases in sync, replication is a process that continuously automatically reproduces data between two databases although schema updates are also possible. Replication Types Database replication can be done in at least three different ways: Snapshot replication: Data on one server is simply copied to another database on the same or on a different server.
Merging replication: Data from two or more databases is combined into a single database. Transactional replication: Users receive full initial copies of the database and then receive periodic updates as data changes. Like synchronization, replication can be either Homogenous or Heterogeneous: Homogenous: Same source and target DBs, i.
Percona to Percona, MariaDB to MariaDB, MySQL to MySQL. Heterogeneous: Dissimilar source and target DBs, i. Oracle to Microsoft SQL Server, PostgresSQL, to Amazon DynamoDB, MySQL to Amazon Aurora A scenario where Heterogeneous replication would be required would be where one or more external business partners employ a different database type than our own.
Sakila MySQL database structure in Navicat Premium 12 Snapshot replication As described above, Snapshot Replication puts two databases in sync by copying data from one database to another on the same or on a different server. Creating a Data Synchronization Job A data synchronization profile must first be created in order to automate it as a replication process. The Data Synchronization Options tab contains only a few Compare Options checkboxes. We can leave them as is: The next step of the Data Synchronization wizard is for mapping tables.
Target tables may be selected via a dropdown list. Difference Options The kind of differences to show may be selected from a dropdown list. Here are the possible options: Difference: Show all records that are different in source and target tables. Insert: Only show the records that do not exist in the target table. Update: Only show the records that exist in both source and target tables having different values. Delete: Only show the records that do not exist in the source table.
Same: Show the records that exist in both source and target tables having identical values. All Rows: Show all records in source and target tables. To begin, click the Automation button in the main toolbar.
Then click on New Batch Job in the Objects toolbar to open a New Batch Job tab. That will make saved jobs for that database appear in the Available Jobs bottom pane. In the Available Jobs pane, select the Data Synchronization job type, and then move the job from the Available Jobs list to the Selected Jobs list above by double-clicking or dragging it. You can delete the jobs from the Selected Jobs list in the same way. Click the Save button on the Automation toolbar and provide a descriptive name in the Save dialog.
That will enable the Set Task Schedule and Delete Task Schedule buttons. The General tab In the General tab of the Task Schedule dialog, you may provide a description for the task as well as provide several options for its execution.
Within the Security Options frame, you may configure which user or group account to run the task under. There is also an option to run the task whether the user is logged on or not. If you do choose that option, you’ll have provide your OS user password in Windows Scheduler when you save the schedule. Triggering the Task The Triggers tab lists the task’s schedule. Click the New button to bring up the New Trigger dialog: The same task may run according to numerous schedules.
