    This dissertation describes the results of a research project which was undertaken at Loughborough University of Technology. The basic objectives of the research project were: (1) to investigate the management elements required for organising the development of an Economic Data Bank (EDB), with particular emphasis on the requirements of a developing nation; (2) to investigate the sociological, political and technical implications associated with organising the development of an EDB in a developing nation. A theoretical framework was established for this study. This was dene after an extensive search and review of literature was performed in the areas of data and data base management systems, management information systems, and computer technology in general.

    The application of message passing to concurrent programming

    The development of concurrency in computer systems will be critically reviewed and an alternative strategy proposed. This is a programming language designed along semantic principles, and it is based upon the treatment of concurrent processes as values within that language's universe of discourse. An asynchronous polymorphic message system is provided to enable co-existent processes to communicate freely. This is presented as a fundamental language construct, and it is completely general purpose, as all values, however complex, can be passed as messages. Various operations are also built into the language so as to permit processes to discover and examine one another. These permit the development of robust systems, where localised failures can be detected, and action can be taken to recover. The orthogonality of the design is discussed and its implementation in terms of an incremental compiler and abstract machine interpreter is outlined in some detail. This thesis hopes to demonstrate that message-oriented communication in a highly parallel system of processes is not only a natural form of expression, but is eminently practical, so long as the entities performing the communication are values in the languag

    This open access book constitutes the proceedings of the 30th European Symposium on Programming, ESOP 2021, which was held during March 27 until April 1, 2021, as part of the European Joint Conferences on Theory and Practice of Software, ETAPS 2021. The conference was planned to take place in Luxembourg and changed to an online format due to the COVID-19 pandemic. The 24 papers included in this volume were carefully reviewed and selected from 79 submissions. They deal with fundamental issues in the specification, design, analysis, and implementation of programming languages and systems
