Firebird vs. H2 vs. HyperSQL DataBase vs. dbForge Data Compare for PostgreSQL Comparison Chart

Welcome to H2, the Java SQL database. In embedded mode, an application opens a database from within the same JVM using JDBC. This is the fastest and easiest connection mode. The disadvantage is that a database may only be open in one virtual machine (and class loader) at any time. As in all modes, both persistent and in-memory databases are supported. There is no limit on the number of database open concurrently, or on the number of open connections. The mixed mode is a combination of the embedded and the server mode. The first application that connects to a database does that in embedded mode, but also starts a server so that other applications (running in different processes or virtual machines) can concurrently access the same data. The local connections are as fast as if the database is used in just the embedded mode, while the remote connections are a bit slower.

dbForge Data Compare for PostgreSQL is a GUI tool for table data comparison and synchronization. It helps to custom-tailor the detection of data differences between two PostgreSQL tables, establish smart management of inconsistencies and safe deployment of changes. This PostgreSQL diff tool also delivers the generation of the PostgreSQL data synchronization scripts with multiple options to keep your PostgreSQL data in sync. Key Features: Accelerate routine tasks with integrated AI Assistant Compare, analyze and synchronize data in PostgreSQL databases Generate SQL scripts to migrate content between databases Copy lookup data from development databases to staging or production Keep an accurate history of all previous PostgreSQL database records Restore missing or damaged data to a single row Automate routine synchronization tasks from the command line Operate with the latest versions of PostgreSQL and Amazon Redshift Connect to IBM Cloud (via SSL) and Amazon Aurora
