Over the last few years, object-oriented programming has been recognized as the best way currently available of structuring software systems. It emphasizes grouping together data and the operations performed on them, encapsulating the whole behind a clean interface, and organizing the resulting entities in a hierarchy based on specialization in functionality. In this way it provides excellent support for the construction of large systems. Up to now, there has been relatively little effort to develop formal theories of object-oriented programming. However, for the field to mature, a more formal understanding of the basic concepts of object-oriented programming is necessary. This volume presents the proceedings of the School/Workshop on Foundations of Object-Oriented Programming (FOOL) held in Noordwijkerhout, The Netherlands, May 28 - June 1, 1990. The workshop was an activity of the project REX (Research and Education in Concurrent Systems).

The emergence of new paradigms for data management raises a variety of exciting challenges. An important goal of database theory is to answer these challenges by providing sound foundations for the development of the field. This volume contains the papers selected for the third International Conference on Database Theory, ICDT'90. The conferences in this series are held biannually in beautiful European cities, Rome in 1986 and Bruges in 1988 with proceedings published as volumes 234 and 326 in the same series. ICDT'90 was organized in Paris by the Institut National de Recherche en Informatique et Automatique. The conference features 2 invited presentations and 31 papers selected from 129 submissions. The papers describe original ideas and new results on the foundations of databases, knowledge bases, object-oriented databases, relational theory, transaction management, data structures and deductive databases. The volume offers a good overview of the state of the art and the current trends in database theory. It should be a valuable source of information for researchers interested in the field.

The algebraic specification of abstract data types is now a well establishedresearch topic in computer science. This area influences both applications and theoretical foundations of methodologies which support the design and formal development of reliable software. The Seventh Workshop on Specification of Abstract Data Types took place in Wusterhausen/Dosse, April17-20, 1990, and was organized in cooperation with the ESPRIT Basic Research Working Group COMPASS. The main topics covered by the workshop were: - Modularization - Object orientation - Higher-order types anddependent types - Inductive completion - Algebraic high-level nets.

The approach described in [JonSl, JonS3a, JonS3b] set out to extend operation decom- position methods for sequential programs - such as are used in VDM [Jon90] - to cover concurrent shared-variable systems. The essential step in [JonSl] was to recognise that 1 inter/erence had to be specified. This is necessary in order to achieve a notion of compo- sitionality - contrast [Owi75]. Rather than the many erudite definitions of composition- ality (e. g. [ZwiSS]), the view taken here is that, when a development task is decomposed into sub-tasks, these must be simpler than the original 'task. This is easy to achieve for sequential programs: decomposing a specified operation S into (Sl; S2), the specifica- tions of the Sj should neither include unnecessary information from each other nor from the context (i. e. S). An interesting discussion of the 'Quest for Compositionality' (in the context of concurrency) is contained in [dRS5, dRS6]. The rely/guarantee idea provided an existence proof that specifications and developments could be made powerful enough to cope with some forms of interference. The work initially attracted little attention but 2 3 there have recently been some critiques and attempts to extend the work * Most notably, Ketil St~len's thesis [St~90] addresses the main shortcomings of [JonSl]: the fact that no attempt had been made to handle synchronization has been remedied by adding a wait condition and other limitations of expressiveness have been shown to succumb to the judicious use of auxiliary variables.

ECOOP '91 is the fifth annual European Conference on Object-Oriented Programming. From their beginning, the ECOOP conferences have been very successful as a forum of high scientific quality where the newest devel- opments connected to object-oriented programming and related areas could be presented and discussed. Over the last few years object-oriented technology has gained widespread use and considerable popularity. In parallel with this, the field has matured scientifically, but there is still a lot of room for new ideas and for hot debates over fundamental issues, as these proceedings show. The 22 papers in this volume were selected by the programme committee from 129 submissions. Important issues discussed in the contributions are language design, specification, databases, concurrency types and software development.

Currently, the field of information systems technology is rapidly extending into several dimensions. There is the semantic dimension (including object orientation, data deduction and extended knowledge representation schemes), there is improved systems integration, and there are new tools. All these extensions aim to provide semantically richer and better engineered information systems that allow for more adequate and complete representations and thus extend the effective use of database technology to a wider class of applications. Database researchers and developers, whether they are committed to application or to system construction, are convinced that next-generation information system technology will be heavily determined by a handful of new concepts that they have to understand and work out in detail now. This volume concentrates on the following topics: - Extended data types and data models, database programming languages; - Rule-based data deduction, expert systems, knowledge bases; - Object orientation and semantic data modelling; - DB application development, methodologies and tools; - Interface technology, parallelism, interoperability, ...; - New database applications.

This monograph reports the development of an approach to computer-aided control system design (CACSD). Of primary concern is the quality of cooperation between the designer and his computer. The designer is suggested to treat a CACSD problem as a search problem, in which he and the computer cooperate to locate satisfactory designs among sets of candidates. Interactive Multi-Objective Programming (IMOP) is employed to define the level of abstraction as well as the organization of the design facilities in the computer.

This volume contains a selection of papers presented at the Seventh Logic Programming Conference that took place in Tokyo, April 11-14, 1988. It is the successor to the previous conference proceedings published as Lecture Notes in Computer Science Volumes 221, 264 and 315. The book covers various aspects of logic programming such as foundations, programming languages/systems, concurrent programming, knowledge bases, applications of computer-aided reasoning and natural language processing. The papers on foundations present theoretical results on "narrowing," a proof strategy for proving properties of Prolog programs based on inductionless induction and several issues in nonmonotonic reasoning. Of special interest to mathematicians is the paper on computer-aided reasoning, which describes a system for assisting human reasoning. Natural language application papers treat the lexical analysis of Japanese sentences, a system that generates a summary of a given sentence and a new knowledge representation formalism suited for representing dynamic behavior by extending the frame system.

The papers included in this volume were presented at the Conference on Mathematics of Program Construction held from June 26 to 30, 1989. The conference was organized by the Department of Computing Science, Groningen University, The Netherlands, at the occasion of the University's 375th anniversary. The creative inspiration of the modern computer has led to the development of new mathematics, the mathematics of program construction. Initially concerned with the posterior verification of computer programs, the mathematics have now matured to the point where they are actively being used for the discovery of elegant solutions to new programming problems. Initially concerned specifically with imperative programming, the application of mathematical methodologies is now established as an essential part of all programming paradigms - functional, logic and object-oriented programming, modularity and type structure etc. Initially concerned with software only, the mathematics are also finding fruit in hardware design so that the traditional boundaries between the two disciplines have become blurred. The varieties of mathematics of program construction are wide-ranging. They include calculi for the specification of sequential and concurrent programs, program transformation and analysis methodologies, and formal inference systems for the construction and analysis of programs. The mathematics of specification, implementation and analysis have become indispensable tools for practical programming.
