Supported databases

RoboHelp Server connects to Apache Derby, Oracle (19c, 12c), Microsoft SQL Server, or Microsoft SQL Server Express Edition database management systems.

Apache Derby
It is an open source relational database created in Java. A full-fledged Derby system consists of a system directory, zero or more databases, and a system-wide configuration. For RoboHelp Server, the Derby system directory is set as <RHS-Install-Path>\database.
Microsoft SQL Server

Microsoft SQL Server is a relational database management system capable of handling large amounts of data and many concurrent users. When a client application requests data, the server retrieves or updates the data. Microsoft SQL Server can roll back transactions. It does not commit a partially entered record to the database.

Oracle

The Oracle database management system provides for the definition, storage, and management of data in a centralized area. It supports client-server environments, large databases, space management, concurrent database users, high transaction-processing performance, openness, compliance with industry standards, manageable security, portability, compatibility, and connectivity.

Microsoft SQL Server Express Edition

Microsoft SQL Server Express Edition is a relational database management system (RDBMS) produced by Microsoft. Its primary query languages are MS-SQL and T-SQL.
