Languayes achieve this, MQT-Engine provides a two-step query transformation mechanism: forst, queries expressed with a model query language are transformed into a Query Language Independent Model QLI Model ; and then QLI Model is transformed into a database-specifoc query that is executed directly over the database. And that improve access to the database but still have this terrible examples of database query languages of the database machine to, to datqbase in, in order to do your query.

Erregistro soila Model query transformation framework- MQT: from EMF-based model query languages to persistence-spefic query languages dc. Most recent approaches propose using database back-ends. However, these languages commonly require examples of database query languages in-memory all the model elements that are involved in the query. In the case of how long should your first date be that traverse models most commonly used type of queries they require to load entire model what is the difference between nosql and relational database. This loading strategy causes memory problems when operated models are large.

Most database examples of database query languages provide database-specific query languages that leverage capabilities of the database engine better performance and without requiring in-memory load of models for query execution lower memory footprint. In this dissertation we present MQT-Engine, a framework that supports execution of model query languages but with the e ciency in terms of memory and performance of a database-specifoc query language. To achieve this, MQT-Engine provides a two-step query transformation mechanism: forst, queries expressed with a model query language are transformed into a Query Language Independent Model QLI Model ; and then QLI Model is transformed into a database-specifoc query that is executed directly over the database.

This mechanism provides extensibility and reusability to the framework, since it facilitates the inclusion of new query languages at both sides of the transformation. A prototype of the framework is provided. The prototype has been evaluated with two experimental evaluations. First evaluation is based on the reverse engineering domain.

Obtained results show that MQT-Engine is able to execute successfully all the evaluated experiments. MQT-Engine is one of the evaluated solutions showing best performance results for first execution of model queries. In the case of query languages executed over CDO repositories, it is the faster solution and the one requiring less memory. For example, for the largest model in examples of database query languages reverse engineering case it is up to times faster than a model query language executed at client-side, and it requires 23 times less memory.

Additionally, the query transformation overload is constant and small less than 2 seconds. These results validate the main goal of this dissertation: to provide a framework that gives to the model engineers the ability for specifying queries in a model query language, and then execute them with a performance and memory footprint similar to that of a persistence-specific query language.

However, the framework has a set of limitations: the approach should be optimized when queries are subsequently executed; it only supports nonmodification model traversal queries; and the prototype is specific for EOL queries over CDO repositories with DBStore. Therefore, it is planned to extend the framework and address these limitations in a future version.

Sin embargo, este tipo de lenguajes necesitan almacenar en memoria al menos todos los elementos implicados en la consulta todos los elementos del modelo en las consultas que recorren completamente el modelo consultado. Esta estrategia de carga de la información para hacer las consultas provoca problemas de memoria cuando los modelos son de gran tamaño. La mayoría de las bases de datos tienen lenguajes específicos que aprovechan las capacidades del motor de la base de datos mayor rapidez y sin la necesidad de cargar en memoria los modelos menor uso de memoria.

Por ejemplo, SQL es el lenguaje específico para las bases de datos relacionales y Examples of database query languages para las bases de datos Neo4J. Este trabajo propone MQT-Engine, un examples of database query languages que permite ejecutar lenguajes de consulta para modelos con tiempos de ejecución y uso de memoria similares al de un lenguaje específico de base de datos. MQT-Engine realiza una transformación en dos pasos de las consultas: primero transforma las consultas que han sido escritas con un lenguaje de consulta para modelos en un modelo que es independiente del lenguaje QLI Model ; después, el modelo generado se transforma en una consulta equivalente, pero escrita con un lenguaje específico de base de datos.

La transformación en dos pasos proporciona extensibilidad y reusabilidad ya que facilita la inclusión de nuevos lenguajes. El prototipo se ha evaluado con dos casos de uso.
