Managing Data Access Dynamically
Writing and reading access diagrams define data access statically. A person sees objects belonging to his/her reading access area, and can modify objects belonging to his/her writing access area.
You can define dynamic rules for reading or writing data access.
Dynamic rule:
• defines for a person, his/her reading or writing access rights on a given object
• can be based on characteristics of:
• an object
• of a person
• an object or person
• can be associated with one or several profiles
