Transformation of SBVR compliant business rules to executable FCL rules

The main source of changing requirements of the dynamic business environment is response to changes in regulations and contracts towards which businesses are obligated to comply. At the same time, many organizations have their business processes specified independently of their business obligations (which include adherence to contracts laws and regulations). Thus, the problem of mapping business changes into computational systems becomes much more complicated. In this paper we address the problem by providing an automated transformation of business rules into a formal language capable of directly mapping onto executable specifications. The model transformation is consistent with MDA/MOF/QVT concepts using ATL to perform the mapping. Business rules are compliant to SBVR metamodel, and are transformed into FCL, a logic based formalism, known to have a direct mapping onto executable specifications. Both, source and target rules are based on principles of deontic logic, the core of which are obligations, permissions and prohibitions.

A Business Rule Engine Applied to Egovernment Services Integration

A great part of applications is increasingly based on the Internet and the needs for changes in these applications happen in shorter and shorter periods. Companies, governments and people who wait for almost instantaneous implementations of those changes stimulate this scenario of high demand for changes. In the context of these fast changes, the approaches based on business rules are aiming for an implementation of solutions that are more flexible to changes and that are in a language easily understandable to business people in a business perspective. This article presents a proposal of a Business Rule Engine customized for e-Government applications, considering the componentization and/or Web “servicification” of life event applications with access to several legacy back office systems. The proposed Business Rule Engine is in conformance with the Business Semantics of Business Rules (BSBR) meta-model, which is in its final phase of specification by OMG.

Business rules in a service development and execution environment

In the current Web based enterprise systems the need of changes in these systems happens in periods shorter and shorter. Considering that some business logic portions are quite volatile and susceptible to the changes and other portions are quite stable and less susceptible to the changes, this paper introduces a model that can capture business changes and quickly implement them into computational systems. The model includes an approach for fast development and execution of services considering that the volatile portions of business logic can be externalized as business rules and the stable portions as Web services. It is proposed a framework for Web services composition based on business rules and service ontology. The framework provides support for business rules definition using a friendly language to the business analysts, for Web services discovery in the business rules definition time, and for making connection between the business rules and Web services in the service execution time. Business rules are modeled according to OMGs SBVR metamodel.

Business Rules in a Model Driven Service Environment

In the current globalized world, characterized by strong Web based interactions, relationships between people and organizations are subject to fast changes. This situation justifies the need for an approach that can capture business changes and quickly implement them into computational systems. Considering that some business logic portions are quite volatile and susceptible to changes and other portions are quite stable and less susceptible to changes, a model for flexible service integration using business rules and service ontology is proposed. The volatile portions are externalized as business rules and the stable portions as Web services. This paper presents the main concepts of the model and an overview of the proof of concept applied to validate the model.

Using Metamodels to Promote Data Integration in an E-Government Application Scenario

The increasing popularization of Internet has created unprecedented expectations and promises when dealing with a more intelligent use of the available data. This use is based on metadata and on a new dimension of metadata modeling techniques. An initiative supported by OMG culminated in the current MOF — Meta-Object Facility specification, which is an open standard with facilities to definition and manipulation of metadata and metamodel. This paper describes a metadata management system that is based on the MOF specification and presents one usage of this system in an egovernment scenario.
