DAB (Database Application Builder) is a configurable software product that allows users to build their own databases for managing business processes and entities. It removes the need for custom application development and the shortfalls of using spreadsheets by providing security, workflow capabilities, integration with other systems, and version control. The DAB module can support processes like lessons learned databases, project timelines, requests for deviation/waiver, and inventory management. It is compliant with several ECSS space industry standards and offers benefits like easy configuration, accessibility from any web browser, and integration with other modules in the ECLIPSE software.
