If true, on feature level, the respective attribute or association serves as a primary key (component) of this class, i.e. specifically an ORM will use this attribute instead of generating an artificial internal ID attribute. Note that there is a related property in XMLogic.

If true, next to the mapped persistant instance of an attribute it's application domain type instance is kept in the state adapter, too. Reasons might be caching or alternate conversion procedures, e.g. loading into existing instead of creating new values.

Applies to

▸ Model elements: ☐ packages ∙ ☑ classes ∙ ☐ attributes ∙ ☐ operations ∙ ☐ association ends ∙ ☐ states

Name of the associated database table. Defaults to class name in uppercase/underscore notation with the prefix "T_".

If defined, all tables in the respective package will be prefixed with this name.

If used on classes, the version identifier of the associated database table. Defaults to empty.

If used on packages, it applies to all classes contained in this package.

If used on attributes or associations in the technical model, the version identifier of the associated database table of the attribute type or of the type at the other end of an association. Used to ensure consistency when migrating database schemas.

If true, during generation of JPA mappings a crosscheck is performed whether a previous mapping for the given table version was already created and whether any referenced tables (according to model associations) have the same versions. If not, an error is reported, explaining that the table version at hand needs to be incremented as well.

▸ Model elements: ☐ packages ∙ ☑ classes ∙ ☐ attributes ∙ ☐ operations ∙ ☐ association ends ∙ ☐ states

Name of the class to be used as a discriminator in associated database tables. Used in inheritance relationships in the base table to identify the specific derived class. Defaults to the interface name plus possibly an implementation postfix. To save storage space, the use of very short abbreviations can be considered. In that case, typically the size of the corresponding column in relational tables ha to be shorteded, too (e.g. default in JPA/eclipselink is varchar(31)).

Deprecated: please use the more comprehensive solution with Stereotype Unique and and property XMUnique/Groups.

Optionally specifies the name of a group of attributes which have to be unique in conjunction. In other words, all attributes with the same UniquenessGroup name belong to such a group, whose value combinations are restricted by a uniqueness constraint.

Apart from being initialised, the values of this class are not modified, i.e. the respective AllSet is constant. This is typically used with enumerations. Specifically, an underlying database is not required to load these values more than once and keep the respective query result in memory.

A list of changes of the respective feature or element, ordered by occurence, from first change to latest change. For each change, the respective table version is given.

The list is used to automatically create migration scripts which can be used to move data from an existing database to a database with a new version and a respective modified schema.

Indicates an aggregate realm to which this class and it's instances belong. Realms indicate that the contained items belong logically together, typically they are used, stored, loaded, imported and exported as a bundle, while items outside the realm might just be referenced in some way.

This concept is related to DDD's 'Bounded Contexts'.
