+ This use case shows how weaving models and model transformations are used to translate SQL-DDL (Data Definition Language) into KM3 (a
+ modeling technical space) and to translate KM3 into SQL.
+ In model management platforms, this use case is considered an application of <a href="#modelgen">ModelGen</a> operations.

+
+ <p align="justify">
+ The development of bridges between different technical spaces is a complex process divided in several phases. This use case illustrates
+ a bridge between an SQL-DDL file into a KM3 file. The SQL-DDL file conforms to a SQL grammar, for example with standard CREATE
+ TABLE statements. KM3 is a standard language for defining metamodels for the modeling world.
+ <p/>
+ The first step of the briding process is to inject the SQL-DDL file into the EMF technical space (Ecore is the metametamodel).
+ The injection creates an SQL-DDL model that conforms to an SQL-DDL metamodel (see Figure 1.a). This metamodel is created manually by a developer.
+ <p/>
+ Then a weaving model (<i>Mw</i>) is created between the SQL-DDL and KM3 metamodels. <i>Mw</i> conforms to <i>MMw</i>, which is an extension to the
+ <a href="http://www.eclipse.org/gmt/amw/zoo/#AMW%20core">core weaving metamodel</a>. This extension contains different kinds of links that
+ define the equivalences between the elements of SQL-DDL and the elements of KM3. However, these two metamodels have different expressivenes. This means
+ it is not always possible to link all the elements of SQL and KM3. For instance, a KM3 <i>Class</i> does not have a "default value"
+ property; a SQL-DDL <i>Table</i> does not have references.
+ <p/>

+ <br /><br />
+ <b>1. Injection and weaving</b>
+ </p>
+
+ The weaving model is used as specification to produce model transformations (in ATL). We implement a
+ higher-order transformation (HOT) based on a generic transformation pattern. This HOT takes the weaving model as input
+ and produces a transformation model as output (Figure 2.a). This output transformation is used to transform a SQL-DDL model into a
+ KM3 model (Figure 2.b).
+
+ <p align="center">
+ <img src="../resources/modelgen_hot.png"/>
+ <br /><br />
+ <b>2. Transforming KM3 model into KM3 file</b>
+ </p>
+
+ The last step of the bridging process is the extraction of the KM3 model (with KM3 concepts such as Class, Attribute, Reference) into the
+ textual concrete syntax of KM3 (see Figure 3).
