Keep in mind that "database" is not the only accessible type. When required, you can also choose "script folder," "snapshot," "source control," or "backup.
After you specify all the necessary settings in the current tab, press "Next" to continue to the next step in adjusting the database schema synchronization process. If two initially identical databases are being compared, you can just proceed to the comparison process right away by clicking "Compare. Any tab can be accessed at any time if needed — just click the corresponding element in the left pane of the window. You can also save the current settings as a.
In most cases, when changes are being performed between two initially identical databases, pressing "Compare" at this stage will do the job. You can tune various settings in the "Options" tab or just leave them in the default state:.
The "Object Filter" tab allows you to set the objects for comparison. You can also get back to any of the previous steps at any time. The database schema comparison settings window will be closed, and a window with the comparison process progress bar will appear instead:. After the process is finished, take a look at the window. You can change the comparison settings by clicking "Edit Comparison" in the top left corner of the screen.
Also, slightly below, you can find all the servers that were registered earlier:. The "File" option in the main menu allows you to save the schema comparison settings as a.
Here, you can choose the objects that need to be synchronized by selecting the corresponding checkboxes. You can also compare tables even if they have different schemas or the primary key is missing. It easily identifies differences by comparing and syncing servers, schemas, and data and enables a number of scripts to be executed against different servers at the same time.
DB Change Manager tracks and manages complex database schema changes and complies with database audit and reporting requirements. It protects data privacy within the database environment and track changes from multiple major database platforms.
It detects and repairs unwanted database changes by comparing to backups and snapshots. SQL Server Comparison Tool analyzes, compares, and documents the structure of tables, procedures, functions, views, triggers, and relationships. It compares data stored in tables and generate detailed reports displaying results of comparisons or analysis. Altova DatabaseSpy is the unique multi-database query, design, and database comparison tool that even generates elegant charts directly from query results.
Control schema objects , that will be included into synchronization script. Customize synchronization process up to your needs. Automate synchronization process through command line. Preparing for Synchronization Before initializing synchronization process, you can review the schema comparison results and select the schema objects, that will be synchronized.
Schema Synchronization Wizard Schema Synchronization Wizard is designed to guide you through the process of script generation and help to tune the synchronization result. Customizing Synchronization The wizard includes advanced options for customization of SQL synchronization script.
Bi-directional replication, such as merge replication is not supported. Azure Data Factory Integration. Synchronise only the data you need to — When synchronising with an on-premises database, then the data you synchronise is typically based on the queries you write, so you have complete control over what data and objects are synchronised.
Error handling and alerting — ADF allows you to build custom pipelines with robust error handling and email workflows.
If transactional consistency with the source database is important, then this could be very complex to implement in a large database that has many related tables. Transactional replication on the other hand, reads transactions from the transaction log and therefore the impact on other transactions is usually minimal. Higher cost — ADF is a paid service and you should familiarise yourself with the pricing model. Transactional replication does not support this. Eventual consistency is guaranteed — Microsoft guarantees that all changes will be synchronised and no data loss will occur.
The resource requirements for the Hub database can be significant, especially if you add a lot of databases to the sync group. This typically will have a higher performance impact on the source database than transactional replication.
