New Directions for IT Governance in the Brazilian Government

This article presents an IT Governance Framework and a Competency Model that are being developed to identify the intellectual capital and the strategic actions needed to implement an efficient IT Governance program in the Brazilian Government. This work in progress is driven by the premise that the human assets of an organization should adhere to a set of core competencies in order to correctly prioritize and achieve business results that, regarding government issues, relate to public resources administration. It is now widely accepted that IT Governance may help the organization to succeed in its business domain; consequently, through effective investment policies and correct IT decisions the organization can align business needs with IT resources, achieving highly integrated business services.

A domain-driven approach for enterprise development, using BPM, MDA, SOA and Web Services

This paper presents preliminary study results of a prototype architecture created with the purpose of using a domain-driven approach to shorten the development of software projects. It is accepted that domain based development is playing an important role on IT projects today. The following discussion presents a way of using different project sites to work together and establish a shared development environment. Using a set of standards and theories such as BPM, MDA, SOA and Web Services, the proposed architecture indicates that, with the aid of standard and controlled techniques, it is possible to obtain significant gains on software scheduling and cost.

A Domain-Driven Development Approach for Enterprise Applications, Using MDA, SOA and Web Services

It is accepted that domain based development is playing an important role on IT projects today. Following such idea, this paper presents preliminary study results of a prototype architecture created with the purpose of using a domain-driven approach to shorten the development of software projects. Our discussion presents a way of sharing business domain models, developed in different project sites, to work together and establish a cooperative development environment. Using a set of development and architectural standards, and modelling theories such as MDA, SOA and Web Services, the proposed architecture indicates that, with the aid of standard and controlled techniques, it is possible to obtain significant gains on software scheduling and cost.

A Practical MDA Approach for Autonomic Profiling and Performance Assessment

By releasing their Model Driven Architecture (MDA) as a new standard, the Object Management Group (OMG) [1] proposed a new development concept toward existing traditional paradigms. It set a new exciting research area in which it would be possible to develop truly independent and powerful programming environments capable of achieving new levels of productivity, performance and maintainability. With this goal in mind, this paper describes a research conducted with the purpose of improving database performance through the union of autonomic computing aspects and MDA. It is widely accepted that the model development approach is gaining importance in IT projects today; therefore the technique discussed here, presents a way of assessing performance, identifying flaws and improving software activities in order to create a self-managed environment. With new defined stereotypes and tagged values; in conjunction with profiling libraries, and relying on autonomic aspects, the proposed extension enables code generation in order to conduct a thorough set of performance analysis, indicating the best suitable database configuration for a given functionality. After setting the underlying problem, explaining tools configuration and concepts and describing the profiling technique, it presents a study based on a real project conducted by the Brazilian Ministry of Defense.

An MDA Approach for Database Profiling and Performance Assessment

This paper describes a Model Driven Architecture (MDA) approach for assessing database performance. The increase in the area of component-based development is reaching a point where performance issues are critical to successful system deployment. It is widely accepted that the model development approach is playing an important role on IT projects; therefore the profiling technique discussed here presents a way to assess performance and identify flaws while performing software construction activities. The approach is straightforward: using new defined MDA stereotypes and tagged values in conjunction with profiling libraries, the proposed MDA extension enables code generation to conduct a thorough set of performance analysis elements. This implementation uses the well-known MDA framework AndroMDA [2], the profiling libraries JAMon [11] and InfraRED [15], and creates a Profiling Cartridge, in order to generate the assessment code.

A Study Case on Domain-Driven Development, Using MDA, SOA and Web Services

This paper presents preliminary study results of a prototype architecture created with the purpose of using a domain-driven approach to shorten the development of software projects. Using a set of standards and theories such as MDA, SOA and Web Services, the proposed architecture indicates that, with the aid of standard and controlled techniques, it is possible to obtain significant gains on software scheduling and cost.
