One of the most important task in an application development process is a database management and data manipulation. Nearly every programming toolkit includes tools, constructs or components for manipulation with database content and structure. DatabaseExplorer is an open-source cross-platform software tool for C++ programming language and wxWidgets toolkit which makes database structure management and data manipulation easy. It provides simple and intuitive GUI interface for handling of multiple different database engines and stored data. The application can be used as a stand-alone tool or as a plugin for well known CodeLite IDE. This paper deals with the application description and reveals its internal structure, used technologies and provides simple use case scenario.
