EXPRESS Data Manager™

Data Interoperability Solutions resolve business issues like:
  • Data exchange
  • Data sharing
  • Data integration
  • Data archival
EXPRESS Data Manager™ (EDM) offers functionality for all four domains. You may use it to build data translators/converters from one data format to another one, where one of them may be, but does not need to be an international standard, such as, ISO 10303 STEP or PLCS. You may apply EDM to share data in a common database. You may implement methods to integrate and merge data from many sources into one joint data model, for example into PLCS. Or you may want to store your data for a long time in a durable open and standardized data format.


EXPRESS Data Manager™

EXPRESS Data Manager™ is a comprehensive suite of model-driven database systems implementing interoperability for the design and operational life of a product, supporting work processes for data exchange, data sharing, data quality and long term data archiving and retention. EXPRESS Data Manager™ implements fully the methodology of ISO 10303 (STEP) and is the tool of preference for international open standards, such as STEP, PLCS, buildingSMART, POSC/CAESAR and others.
