OpenB concepts - Modeling Engine

  1. 1. Modeling engine OpenB concepts
  2. 2. Create domain models
  3. 3. Create domain models  The modeling engine allows you to create the following kind of models:  Simple models  Authorizable models  Auditable models  Versioned models
  4. 4. Model types – simple models  Basic domain model  With only key and name and description metadata.
  5. 5. Model types – authorizable  Basic domain model  With only key and name and description metadata.  Owner and access rules for groups and/or single users.
  6. 6. Model types – auditable  Basic domain model  With only key and name and description metadata.  Last access time and user.  Moment of creation.  Moment of last update.
  7. 7. Model types – versioned  Basic domain model  Versioning is hidden for users.  Trigger based, for example:  based on the creation date of a parent model  Each change creates a new version
  8. 8. Model types – versioning – usages  Allows for change tracking  Allows for ‘concept versions’  Allows for data warehousing.
  9. 9. Repositories
  10. 10. Repositories  Different types of repositories are supported.  Seamless linking of different repository types.  Expression based queries for business rules and view rules.
  11. 11. Repositories – seamless linking  Repository models can use properties of other repository kinds.  For example: An SQL repository can have models with properties linking to an XML repository.
  12. 12. Repositories – expressions  Internal DSL for querying repositories  Internal use of Lambda expressions.
