Abstract
Abstract The present invention relates to a process for manipulating data models for the transfer of models between a plurality of software engineering tools (Ta, Tb, Tc, Td, etc.) and for the application of transformation rules to a model, wherein the transformation of data models is carried out by means of gateways (Ba, Bb, Bc, Bd, etc.) which make it possible to convert the format of one tool to the format of another tool by passing through a unique neutral intermediate format (NIM). The present process is remarkable in that the development of the gateways, in accordance with the so-called object-oriented approach, is carried out in an executed language, the gateways being executables which allow the transformation of a data model in several steps activated successively, in a systematic or conditional way, by means of a command language which describes a logic for dynamic concatenation of the steps, concatenation being a named, parameterized procedure. Each step is an executable whose code is developed from an array of reusable classes, while the activation of a procedure requires simply that the name and the parameters of the corresponding procedure be supplied.

Claim 1
Independent Claim
155 words
A process for manipulating data models for the transfer of said data models among a plurality of software engineering tools having an initial format and for the application of transformation rules to one said model, transforming the data models by means of gateways to convert the initial format of one tool into a format of another tool by passing the initial format through a unique neutral intermediate format, developing the gateways, in accordance with an object-oriented approach, in an executed language, the gateways being executable which allow the transformation of a data model in several steps, activating the steps successively, in a systematic or conditional way, using a command language which describes a logic for dynamic concatenation of the steps, concatenation being a named, parameterized procedure, each step being an executable whose code is developed from an array of reusable classes, and providing the name and the parameters of the corresponding procedure to be activated.

Claim 3
Dependent Claim
76 words
The process for manipulating data models according to claim 1, characterized in that in order to develop a gateway, a reusable class is created which makes it possible to represent models and metamodels stored in memory in a repository or in an external file, using a dynamic allocation of the modeling objects, the objects of said class integrating an array of memory structures and supplying functions for manipulating the data of a model loaded into memory.
Claim 4
Dependent Claim
132 words
The process for manipulating data models according to claim 1, characterized in that in order to develop a gateway, a reusable class is created which makes it possible to code and decode different tool export file formats, which reusable class encapsulates the tool export records and is used to describe the record formats of an import file, whereas upon initialization, while a metamodel of a tool is read with the aid of the class for representing the models and metamodels sorted in memory from a text file, the code of the gateway makes it possible to read the tool export file, to access the member fields of the records and to create the objects and their properties using the functions of the class for representing the models and metamodels stored in memory.
Claim 5
Dependent Claim
57 words
The process for manipulating data models according to claim 1, characterized in that in order to develop a gateway, a reusable class is created for manipulating character strings, making it possible to handle allocations, concatenations and comparison operators with the substring and dynamic memory reallocation functions while preserving compatibility with the character strings of a C-type language.
