Entities

Entities

• Physical file names for data and variant entities may be up to eight or ten characters in length, depending on your Visual LANSA system settings.

• If an entity's physical file name is longer than two characters less than the maximum number of characters allowed by the system settings, the entity's relationships and user views must have logical view names specified manually.

• If an entity's physical file name is longer than two characters less than the maximum number of characters allowed by the system settings, logical view names for the entity's relationships and user views are optional.  If no logical view name is specified, the modeler will automatically generate a logical view name consisting of the entity's physical file name and a sequential two digit number, as with previous versions.

• You can perform a one-time import of an existing physical or logical file (an External Entity) definition. External entities may be related to logical entities in order to extend existing databases.

• Entity validation is performed dynamically, indicating whether or not the entity is in error prior to build processing.

• The way in which an entity is shown as having a validation or build errors is shown as an inverted red triangle above the top, right-hand corner of the entity shape.
