Alternate Keys

Sometimes analysts model the Identification Function of a class using attributes which are not very intuitive for the users of the OLIVANOVA applications to identify the class instances.

For this reason and to enhance the usability of the OLIVANOVA applications, the Alternate Keys feature has been designed in order to display to the user the instances of a class in a more intuitive or friendly way. This new solution will provide the mechanism to model one or more alternate keys for a class and select one of them to be used by the user interface.

Showing total instances number

The Population Interaction Units allow showing and interacting with several instances, and they retrieve the population of instances by blocks. The user can get feed-back about the number of instances loaded and showed in the Interaction Unit in each block load. But until now it is not possible to know the total number of instances of the data base that satisfy a particular query until the user has requested for all the blocks.

From now on the OLIVANOVA Business Logic layer will be able to return the total number of instances that satisfies a query. So the User Interface layer will get this information to give more valuable feed-back.

• Alternate identification key
  Identify the class’ instances in a more intuitive and friendly way by means of Alternate Identification Key. Like the main Identification Function of a class, these Alternate Identification Keys identify the class’ instances in a unique way. Analysts can model one or more Alternate Identification Keys for a class and select one of them to be used by the user interface.
• NULL value as outbound parameter for a user function
  Now, transaction/operation formulas, it is possible to invoke a user function, outbound arguments, with the NULL value as outbound parameter.
• Multiple Selection for object-valued arguments in services defined as New
  Now, it is allowed to set Multiple Selection for object-valued arguments contained in services defined as New.
• Add check "Add arguments to definition" in the "Global services" tab of the selection dialog (F2)
  In selection dialog, when defining a global transaction, there is a "Add arguments to definition" checkbox on the "Visible services" tab, but not on the "Global services" tab. Add this check.

• Alternate identification keys
  OLIVANOVA Comparator compares the Alternate Identification Key. Like the main Identification Function of a class, these Alternate Identification Keys identify the class’ instances in a unique way.

• Alternate identification keys
  The information about the “Alternate identification keys” has been added in Full Model and Help Messages documentation. This information is showed in several sections of these types of documentation.
  

• Alternate identification keys
  The information about the alternate identification keys is managed in Multilanguage. This data is displayed in the tree of the “Translations in tree” form. Concretely, it appears in a new node called “Alternate identification keys” inside the classes.
  
• Export to Excel
  In this new version, the path where the Excel sheet is generated is requested before exporting. This field is mandatory both for model and fixed texts.
  
• New fixed texts version (5.13)
  The XML file holding the Transformation Engines fixed texts has been updated.
  

• Show, in the Population Interaction Units, the total number of instances in the Database that satisfy a query.
• Define unique keys in a class, not the OID. Its value must be unique in the class population and may be used in the user interface in order to identify the object.

• Now, Population Interaction Units display the total number of instances in the database that satisfy a query.
• Now, the analyst will be able to use Alternate Keys to identify the class’s instances or objects in the user interface.

• Show, in the Population Interaction Units, the total number of instances in the Database that satisfy a query.
• Define unique keys in a class, not the OID. Its value must be unique in the class population and may be used in the user interface in order to identify the object.

• Alternate Identification Keys.
• Total number of instances fulfilling a query.
• Filter optimization checking at execution time
  The optimization of filters, navigational filters and horizontal visibility filters is now checked at execution time considering the value of filter variables, connected agent, SelectedObject instance or service arguments when they are part of the filter formula.
