How to synchronize a developer's local database between a laptop and a work PC?

Working on complex projects often requires a local copy of the database for testing and debugging code. When a developer switches between different computers, the task of synchronizing the database state arises so that the data on the PC and laptop is always up to date. Direct synchronization of DBMS files between devices is impossible due to locks and differences in software versions.

The main method of transferring data between environments is exporting and importing dumps. A database dump file is created on the source computer using the built-in command-line utilities of the specific DBMS. The resulting SQL script or archive is packed and transferred to the target computer via secure storage or a local network, after which it is deployed in a local database instance.

To automate this process, migration scripts and fixtures can be used. Database version control systems allow you to fix the schema structure in special migration files. When moving to another computer, the developer simply executes the migration application command, and the database structure is recreated automatically, eliminating the need to transfer heavy dump files.

In cases where the developer needs a full set of real data for testing, specialized data synchronization tools are used. Such utilities can compare the state of the remote and local databases, transferring only modified rows and tables. This significantly speeds up the process of updating the local environment compared to completely re-uploading the entire database.
