Information modeling
Modeling your information is the first step when using RISE to build an information management solution.
The articles in this section are intended to give you an understanding of RISE information modeling. They show standard solutions to common problems and provide an introduction to entity-relationship modeling together with some guidelines. If you're new to information modeling you might considered using the following overall work process:
-
Get your most important objects (entities) in there first
-
Try to relate your important objects to each other
-
Increase model resolution by repeatedly:
-
Adding attributes to objects
-
Refining objects into sub-systems of related objects
-
Refining relations into sub-systems of related object
RISE promotes this approach to modeling by allowing many drawings in a single model. This allows you to model a sub-system in a separate drawing, thus, not cluttering the overview with less relevant details. |

Intro to Entity-Relationships
|
| Here you'll find an introduction to entity-relationship diagrams and the crow's foot notation used in RISE. You also find an article explaining entity-relationships in database terms. |

Information structures
|
| Hierarchic, parent-child, relations or tree-like structures of various types, are perhaps the most common construct in any information model. This article discusses how to accomplish a tree structure when modeling using RISE. |
|
|
Referencing an entity
|
| There are many kinds of relations, in a model, that doesn't represent any actual structure, such as classifications and temporary dependencies. This article covers some general referencing aspects. |
|
|
Information inheritance
|
| Larger models often needs to refer to a set of different objects having a common denominator. This article shows some strategies to handle this. |
|
|
Working with views
|
| Views are combinations of entities in to higher order objects. They provide further specification to the intended use of a model. This section contains article on how to add views to your model. |
|
|
Adding indexes
|
| Read more on how to add indexes and composite unique constraints to your model. |
|
|
Consistency and Refactoring
|
| This article discusses how RISE assures the consistency, including the naming consistency, of a model. It also covers the topic of model life-cycle and refactoring. |

How to use drawings
|
| Shows how use multiple drawing to structure your information model and make it cluttered. |
