This chapter describes the detailed structure of QPR Modeling database. As database is implemented to several different relational database management systems (RDBMSs), the approach in database structure is to generalize model elements and store all data into three tables that include the following data.

1.Element data, basic element attributes and instance data.
2.Graphical presentation of element.
3.Element type–specific attribute data including also relations and hierarchies (database allows hierarchies to be used with all element types).

 

Database has separate tables that describe each element type and what data is saved with it. Also graphical presentation is described separately.

 

Tables

 

Tables of the database are described briefly in the table below. Some database tables store QPR Modeling-specific data (graphical presentation) in binary format. Also measure data is stored in binary format because of performance. If that data is needed, it can be retrieved by opening model in QPR Modeling Client and using measure data export.

Table

Description

PG_ATTRIBUTE

Has one row for each attribute of a model element.

PG_ATTRIBUTE_2

Used to store text and blob attributes.

PG_ATTRIBUTE_TYPE

Stores all the possible attribute types separately for each model.

PG_ELEMENT

Has one row for each model element and separate rows for each instance i.e. at least two rows for each instantiated element (but only one for elements without instances).

PG_ELEM_GRAPH_PROP

Stores graphical presentation of each model element instance.

PG_ELEMENT_TYPE

Has one row for each model element type (defined in Modeling Options dialog).

PG_ELEMENT_USER

Stores relation between user and resources/organization units for portal usage.

PG_ELEMTY_GR_PROP

Stores graphical presentation of each model element type.

PG_FOLDER

Has one row for each folder (used in Open/Save As dialogs like folders in storing files), root model, and branch.

PG_MODEL

Has one row for each model version.

PG_PARAM_DATA

This table can be used to store different QPR Modeling parameters.

PG_VIEW

Stores views (currently only named analysis views).

PG_RESERVATION

Stores reservations for checked out models (each time user checks out a model for editing a row is added).

PG_USER_MODEL

Stores one row for each model to which a QPR Modeling Client user has some rights. Stores also the state of the views separately for each user.

PG_USER_FOLDER_RIGHT

Stores user rights to different folders.

PG_USER_RIGHT

Stores user rights to different models.

PG_TYPE_ATTRIBUTE

Stores multilingual texts and other properties for element and attribute types.

Relationships

 

Relations between database tables (foreign key references) are described in the figure below.

database_relations

Relations between tables (foreign key references are shown with arrows).

Note: User information is stored in a separate database used by QPR User Management System, referential integrity does not exist between it and PG database.

 

The following relations are not mandatory:

Model -> Model

Model -> Folder

Folder -> Folder

Attribute -> Element (When relation to another element is described.)

Attribute Type -> Element Type (When possible relation to specific element type is described.)

 

With all relations the cascade deletion is not allowed.
