چکیده

The model management operator ModelGen translates a schema expressed in one modelling language into an equivalent schema expressed in another modelling language, and in addition produces a mapping between those two schemas. This paper presents an implementation of ModelGen which in addition allows for the translation of data instances from the source to the target schema, and vice versa. The translation mechanism is distinctive from others in that it takes a generic approach that can be applied to any modelling language.

AutoModelGen: A Generic Data Level Implementation of ModelGen

The model management operator ModelGen translates a schema expressed in one modelling language into an equivalent schema expressed in another modelling language, and in addition produces a mapping between those two schemas. AutoModelGen is a generic data level implementation of ModelGen that meets these desiderata. Our approach is distinctive in that (i) it takes a generic approach that can be ...

A schema transformation based approach to generic model management

Shared databases made up of numerous heterogeneous components and used by large numbers of people are wide spread in both industry and academia. Writing programs to access and maintain these databases is a time consuming and difficult task that can take up a significant proportion of an enterprise IT manager’s resources. The situation has worsened recently as new Data Definition Languages (DDLs...

A Multilevel Dictionary for Model Management

We discuss the main features of a multilevel dictionary based on a metamodel approach. The application is an implementation of ModelGen, the model management operator that translates schemas from one model to another, for example from ER to relational or from XSD to object. The dictionary manages schemas and, at a metalevel, a description of the models of interest. It describes all models in te...

Translating Schemas and Data between Metamodels

ModelGen is an operator that automatically translates a source model expressed in a source metamodel into an equivalent target model expressed in a different metamodel. For example, given an XML schema, ModelGen can automatically generate an equivalent relational schema or Java interface. This paper describes a new algorithm for ModelGen with several novel properties. It automatically determine...

Data Clustring Using A New CGA(Chaotic-Generic Algorithm) Approach

Clustering is the process of dividing a set of input data into a number of subgroups. The members of each subgroup are similar to each other but different from members of other subgroups. The genetic algorithm has enjoyed many applications in clustering data. One of these applications is the clustering of images. The problem with the earlier methods used in clustering images was in selecting in...
