Basic Settings: MDM dictionary

The Basic Settings page is used to specify object name, identifier and comment, and MDM dictionary structure is set up:

The checkbox is deselected by default.

To set up dictionary version control, select the Elements can Change in Time checkbox.

After the checkbox is selected, each time a dictionary opens for view, the Determine Parameter Values dialog box opens, in which one can set the Actuality Date parameter:

After the checkbox is selected, the Dictionary Elements tab will contain the Actuality Date parameter, the list of system attributes will contain attributes that enable element version control. Such a dictionary will be named a version one.

After the checkbox is selected, the following options also become available:

Consider Time in Elements' Actual Periods. Selecting the checkbox enables the user to change the type of the INDATE and OUTDATE system attributes from Date (the date is represented without time) to DateTime (with time), which affects only the element date type.
Generate Elements' Actual Periods Manually. Selecting the checkbox enables the user to manually set date ranges for version dictionary elements on the Dictionary Elements tab. Otherwise the range is automatically formed as follows: start date is set to the actuality date, and end date is set to 31.12.2999.

The checkbox is selected by default.

When the checkbox is selected, the Owner attribute is created automatically.

When the Elements have Hierarchy checkbox is deselected, the dictionary becomes one-level, that is, dictionary elements cannot have child elements. On an attempt to deselect the checkbox for a dictionary that has at least one child element, a system message is displayed informing that this operation is not allowed.

The checkbox is deselected by default. The checkbox is available only for outdated dictionary types and is used for compatibility with previous versions.

GUID (Globally Unique Identifier) is the statistically unique 128 bit identifier. Its main feature is the uniqueness that enables the user to create expandable tools and applications without being afraid of conflicts arising due to duplicate identifiers. Although it is not guaranteed that each GUID is unique, the total number of unique keys is so large (2¹²⁸) that the probability of the same key being generated randomly twice is extremely small.

When the checkbox is selected, the Unique Identifier system attribute of the string type is added to the attributes list. This attribute is filled in automatically when elements are added to the dictionary. When this checkbox is selected for a dictionary that already contains elements, the attribute is also filled in automatically.

The checkbox is deselected by default.

To separate discretionary access permissions for dictionary elements:

Make sure that the Use Discretionary Access Control checkbox is selected in the Policies Editor section of the security manager.
Select the Elements have Discretionary Access Permissions checkbox in the dictionary general settings.

After the checkbox is selected, other four mandatory attributes are added to the attributes list of the dictionary that enable the user to set up access permissions for dictionary elements.

The list of access subjects is created on the Access Subjects page.

NOTE. If roles of the information security administrator and the application administrator are separated, after selecting the Elements have Discretionary Access Permissions checkbox and saving the dictionary, the checkbox can be deselected only in the security manager. This checkbox can be selected only by the application administrator or the user who has appropriate permissions.

If the policies editor uses discretionary and attribute-based access control methods at the same time, after the checkbox is selected, the Elements have Attribute-Based Access Permissions checkbox becomes available to apply policies and rules of configured attribute-based access control method for each dictionary element.

The checkbox is deselected by default.

To separate attribute-based access permissions for dictionary elements:

Make sure that the Use Attribute-Based Access Control checkbox is selected in the Policies Editor section of the security manager.
Select the Elements have Attribute-Based Access Permissions checkbox in the dictionary general settings.

After the checkbox is selected, policies and rules of configured attribute-based access control are applied for each composite dictionary element.

The checkbox is deselected by default.

When the checkbox is selected, the Hide attribute of the logical type is added to the list of system attributes. By default, this attribute is set to FALSE for dictionary elements. When the attribute is set to TRUE, the element is hidden in the dictionary element tree.

To display all hidden elements, deselect the checkbox.

Tracking other objects that refer to dictionary elements helps sustain integrity of these objects and prevent possible deletion of elements used in these objects. For example, a dictionary element is used in selection of regular report data area. An attempt to delete such an element brings up a warning message that this element is in use and its deletion may violate other objects' integrity.

The list of objects referring to dictionary elements can be viewed in properties of this dictionary. The checkbox is deselected by default, links to elements are not tracked.
