KS DB Merge Tools for SQLite is a software utility that provides a convenient way for you to compare databases and monitor them for changes. Not only that it allows you to explore the content of an SQLite database, but it also helps you identify differences and apply filters to reveal modifications to tables, indexes, triggers and views.

Compare and merge SQLite databases
You can open any two databases in KS DB Merge Tools for SQLite and explore their content side-by-side. The application reveals table definitions, indexes, triggers, views and pragmas for each in a separate panel. Moreover, new application instances can be opened to load new databases.

KS DB Merge Tools for SQLite can compare both database schema and containing data for multiple tables and views. It allows you to check all the modifications that occurred in all the database fields, but you can also configure it to only reveal new elements or new and changed items inside tables and views. In other words, applying filters to see changes or new elements is possible. Changes between databases can be merged to keep them in sync.

Keeping two or more databases in sync might seem like a challenge but a dedicated application such as KS DB Merge Tools for PostgreSQL can be of great help in this case. As its name suggests, it is specifically designed for PostgreSQL databases, allowing you to synchronize and compare both schemas and data.

Side-by-side comparison of two PostgreSQL databases
Smartly enough, the layout of the main GUI is designed to facilitate side-by-side comparison between two databases. You can easily set up new database connections for each of the two panels and KS DB Merge Tools for PostgreSQL connects to PostgreSQL and starts populating the tables with objects, while also displaying totals, new and changed items in the database schema.

If Oracle is your database management tool of choice, then an application such as KS DB Merge Tools for Oracle is surely of great help. This software utility is designed for database comparison and synchronization, allowing you to compare data and schemas inside two Oracle databases and merge any changes that might occur.

To make it easier for you to spot differences, KS DB Merge Tools for Oracle displays data on two panels, each allowing a direct connection to an Oracle database. A few details are required to help you get started: the server's name and the port number, as well as the connection credentials. The connection can be tested to see if everything works as it should.

There are other connection options besides entering the credentials manually: KS DB Merge Tools for Oracle can use connection strings for each database.
