The basic requisites of a configuration and software distribution environment are presented for maintaining information systems based on heterogeneous technological platforms: mainframe, minicomputers, and personal computers. A preliminary functional study for the ad hoc development of a configuration and software distribution instrument is presented. An evolution towards the IBM repository manager is evaluated as a technological choice to support an internal development of the instrument.<>

Intermodule code analysis is a process by which a programmer can analyze a program consisting of a collection of interconnected modules. A deductive database that records the information needed for intermodule code analysis is presented. The application of a deductive database to this domain utilizes the rule capability for data structuring and facilitates the declarative specification of recursive operations. This deductive database was derived from a conceptual schema, which describes the dependencies that exist in a program. A method for mapping a conceptual schema to a deductive database framework is outlined. An example query is used to show how this database can be used for intermodule code analysis.<>

An integrated environment for the maintenance of software systems written in C is presented. This environment supports all of the C language, including the C preprocessor. The underlying program representation for the environment supports multiple views of the subject system, including source code, syntactic, static semantic, control flow and data flow views. A transformation toolkit supports structured changes to the representation and automatically updates all dependent views. Modifications in one view are reflected in related views.<>

Program slicing is a method of finding all statements that might directly or indirectly affect the values of variables. The concept was first proposed by M. Weiser (1981, 1984). Some of the problems and possible solutions of program slicing within the C language are discussed. Some basic notations and Weiser's original algorithm are presented. Then, slicing problems and solutions are described. For instance, how to find the correct slice in the presence or array and pointer variables and how to find break, continue, and goto statements that have effects on the slice. An algorithm to find the branch statements is introduced.<>

The author describes a large software reengineering project at the Union Bank of Switzerland. Seven bank applications with 203 programs and 432 files were renovated and migrated from a UNIVAC-494 to a UNISYS-1100. The programs were restructured to fit a JSP-DELTA generator. The data were remodeled to fit into a CODASYL database with a data dictionary and a common COPY library.<>

The authors demonstrate the usefulness of change tracking information from the maintenance programmer's perspective. They split the data into logical groups and find the connections between these groups. They describe a method to incorporate problem-solving information in a change tracking database. Problem solving is discussed with regard to structured problem-solving techniques for isolating difficult problems. A relational database structure and queries to access the database are discussed. An example of how the change tracking system supports the maintenance problem-solving process is also included.<>

A project is described where maintenance productivity savings of 70% have been made, at the same time, accompanied by service-level improvements. The author describes the changes made and suggests what the underlying productivity factors may be. The organization was changed into three teams initially to separate the support and maintenance activities with a single service desk. A metrics program was implemented using a problem management system to log incoming queries and problems. A program of preventive maintenance was established. Full management control was established with procedures for the maintenance processes and interfaces, including, for example, testing, quality control, configuration management and version control, release management and problem management.<>

The authors propose to do maintenance with the software system model (SSM) that provides the maintainer with a number of alternative views of the code. To make an understandable presentation of more information than the code contains, the expert system must offer information system capabilities, such as semantic retrieval and intelligent indexing. An analysis of the capabilities and the degrees of assistance of a software evolution expert system (SEES) is given in an incremental framework. The authors address SEES reasoning directed by knowledge in models of views, analyze SEES capabilities, and point out different degrees of assistance and models of views. Some tradeoffs in SEES development are discussed and evaluated. The analysis has led to five functional architectures. Each architecture assumes that one has one or more view models available. The authors describe the results of the first SEES prototype.<>

The authors explain how inheritance and dynamic binding make object-oriented programs difficult to maintain, and give a concrete example of the problems that arise. They show that the difficulty lies in the fact that conventional tools are poorly suited for work with object-oriented languages, and argue that semantics-based tools are essential for effective maintenance of object-oriented programs. The authors describe a system developed for working with C++ programs. This system comprises a relational database system for information about programs, and an interactive database interface integrated with a text editor. They describe the system architecture, detail the database relations, provide informal evidence on the system's effectiveness, and compare it to other research with similar goals.<>

The authors provide insights into the process of deriving objects from code and specifications. Their purpose is to facilitate the more general process of reverse engineering. They concentrate on a method for object identification and give some examples of deriving objects with details on the syntax of the object-oriented notation Z++. The authors provide some further examples of object derivation, concentrating on internal data structures in program code. They detail the relationship between objects and abstract data types, and discuss the concepts of reusability with respect to inheritance hierarchies.<>
