Query Language MQL

Similar to MML, MQL is used to query the model elements using the modeling user interface. Both MML and MQL are understood and executed by the MMS. The result set of the query performed is sent back to the modeling user interface. Both MQL and MML can be embedded in the source code of tools and applications within PEEE. In such case, the result set is sent back to the host application (or tool). Table 5-9 presents example commands from the MQL. [Pg.92]

Similarity to structured query language (SQL) In order to retrieve the model elements in a standard manner, model query language (MQL) is required. Such model query language can be used via user interface similar to SQL. [Pg.81]
