This paper presents an information systems architecture (ISA) model that comprises the integration of information systems, technology, business processes and users in public sector environment. The ISA model presented considers specific aspects of the public sector as well characteristics of information systems development and use in this sector found in the literature and in the studies realised in informatic services brazilian State public enterprises. The model proposed was structured with five components: (a) Government structure (mission and organisational culture, Planning and government platform);(b) Public services (considered the " business" of public structure, with the information for citizens, for top level and government administrative technical);(c) Information systems (by including the legacy systems and executives systems information);(d) Information technology (centred in investment policies and the government computational platforms-as micro-computer and mainframe relationship) and (e) Users (centred in the necessities for public-training, adaptation and use of the SI). The model proposed was submitted to validation from informatic services Brazilian State public enterprises. The results point out the relevance of the integrated vision of their components and they permit to establish strategies for implantation of ISA model, in order to observing public sector specificity.

This paper presents an object oriented framework for task scheduling. This framework can be used in domains such as process-centred software engineering environments, workflow management systems or project management systems. The framework was conceived based on both current methods for the development of frameworks and an existing architectural pattern for process managers. A prototype of the framework was developed using the Java language. The lessons learnt show the experience of extracting a framework from well-known applications that can be reused in practical domains. Thus, this work contributes not only in the production of a framework but also giving insights in the application of novel techniques to the development of frameworks.
