RELATIONAL DATABASE
A data file storage and retrieval model based on a set of defined relationships between two dimensional tables consisting of fields (table items) and rows (data items). From both the programmer and end user point of view, these tables behave like spreadsheets where each row is a record and various operations such as browsing and searching can be performed without knowledge of the actual physical file structure.
Unlike other EPMA software programs that write or store the user's data in "normal" computer files, Probe for EPMA uses a robust industry standard (Microsoft Access) file format based on transactional processing, guaranteeing the preservation of the data regardless of power failures, computer crashes, etc.
