“…In that paper, we outline the original version of the Booster language and methodology and discuss lessons learned in its application to three case studies. The version of the language presented here is quite different from that of [7] and other, earlier papers [8,9]: framing information and other 'compiler directives' are no longer required; the constraint language is now the full first-order predicate calculus, rather than three classes of 'programming constraint'; operations are now characterised as a single predicate, and may be composed using operation references. The transformations are now implemented in a declarative, functional language, more amenable to verification, and can be targeted at different platforms.…”

Highlights• Model-driven tools can reduce the cost of development and verification.• Information systems can be produced automatically from object oriented designs.• A formal, model-driven approach is proposed for use in safety critical systems.• A framework is provided for the correctness of model transformations. AbstractModel-driven engineering is the generation of software artefacts from abstract models. This is achieved through transformations that encode domain knowledge and implementation strategies. The same transformations can be used to produce quite different systems, or to produce successive versions of the same system. A model-driven approach can thus reduce the cost of development. It can also reduce the cost of verification: if the transformations are shown or assumed to be correct, each new system or version can be verified in terms of its model, rather than its implementation. This paper introduces an approach to model-driven engineering that is particularly suited to the development of critical information systems. The language of the models, and the language of the transformations, are amenable to formal analysis. The transformation strategy, and the associated development methodology, are designed to preserve systems integrity and availability.

“…Booster [4] is an object-based language for model-driven development in which operations are described in terms of pre-and post-conditions. The Booster compiler extends the description of each operation with constraints based upon the invariant properties of the model, and uses the resulting model as the basis for the generation of a complete, webbased information system.…”

Many approaches to software specification and design make use of invariants: constraints whose truth is preserved under operations on a system or component. Object modelling involves the definition of association invariants: constraints upon the sets of links corresponding to particular associations, most often concerning type, multiplicity, or symmetry. This paper shows how the definitions of operations may be extended to take account of association invariants, so that they may be properly considered when the operations are implemented. It introduces a formal, objectbased modelling notation in which the process of extension and implementation, and thus the maintenance of association invariants, can be automated, making it easier to produce correct implementations of an object-oriented design.

“…The method language explained here, one aspect of an approach described in general at a previous SBMF workshop [5], is intended for the generation of object databases: data stores in which information is organised as a collection of objects, and acted upon by associated methods. Its syntax is based upon aspects of Z [16] and B [1] languages; its semantics is based upon that of Z [16] and the Refinement Calculus [11].…”

This paper explains how a declarative method language, based upon the formal notations of Z and B, can be used as a basis for automatic code generation. The language is used to describe the intended effect of operations, or methods, upon the components of an object model; each method is defined by a pair of predicates: a precondition, and a post-condition. Following the automatic incorporation of model invariants, including those arising from class associations, these predicates are extended-again, automatically-to address issues of consistency, definition, and dependency, before being translated into imperative programs. The result is a formal method for transforming object models into complete, working systems.
