The document discusses Building Information Modeling (BIM) from a software technology viewpoint. It describes BIM as 3D design with attached information that exists from early design through demolition. There are three layers to BIM software: applications, data models, and data storage. For fluent data flow between software, applications should use a shared data model to prevent data conversions and loss. An optimal approach involves a single shared model stored in a cloud database with a web service for collaborative access.

The requisite data collaboration3754812687654321Single model Distributed data system Single shared model vs privatenative models one sharedmodel data import and export with exchange files only single model data conversions needed no data conversions conversions cause data altering and loss no conversions, no data altering,no data loss duplicate data all datasaved only once multiple GUIDsper object single GUID per object
- 6. Requirements for fluent data flow 1.Applications use the same and shared data model instead of their native and separate models. All information is saved only once making all data conversions dispensable. 2.The schema of a data model must implement the model dividing into independent partial models that can be edited or utilized separately. 3.User accounts along with reserving and releasing edit rights for independent partial models fully prevent all data conflicts and redundancies. 4.A data model schema must allow the free additions of new content and data types by software developers without breaking the compatibility of the whole evolving data model schema. 5.Permanent storage for a data model is a single shared database on a cloud server that all applications can access concurrently. 6.A secure web service with adequate functionality for easy access to the cloud database and model.
