Provides an overview of file design and manipulation and discusses Ada records and files, blocking and buffering, secondary storage devices, search trees, and various types of file organization.
Provides complete coverage of the Ada language and Ada programming in general by recognized authorities in Ada software engineering. Demonstrates the power and performance of Ada in the management of large-scale object-oriented systems, and shows how to use Ada features such as generics, packages, and tasking.
This second edition has been thoroughly updated to instruct readers on the design of fast and flexible file structures. It includes coverage of file structures in a UNIX environment, in addition to a new and substantial appendix on CD-ROM. Other modern file structures such as extendible hashing methods are also explored. This book develops a framework for approaching the design of systems to store and retrieve information on magnetic disks and other mass storage devices. It provides a fundamental collection of tools that any user needs in order to design intelligent, cost-effective, and appropriate solutions to file structure problems.
(a) Design and construction. (1) Each facility or part of a facility constructed by, on behalf of, or for the use of a public entity shall be designed and constructed in such manner that the facility or part of the facility is readily accessible to and usable by individuals with disabilities, if the construction was commenced after January 26, 1992. (2) Exception for structural impracticability. (i) Full compliance with the requirements of this section is not required where a public entity can demonstrate that it is structurally impracticable to meet the requirements. Full compliance will be considered structurally impracticable only in those rare circumstances when the unique characteristics of terrain prevent the incorporation of accessibility features. (ii) If full compliance with this section would be structurally impracticable, compliance with this section is required to the extent that it is not structurally impracticable. In that case, any portion of the facility that can be made accessible shall be made accessible to the extent that it is not structurally impracticable. (iii) If providing accessibility in conformance with this section to individuals with certain disabilities (e.g., those who use wheelchairs) would be structurally impracticable, accessibility shall nonetheless be ensured to persons with other types of disabilities, (e.g., those who use crutches or who have sight, hearing, or mental impairments) in accordance with this section.
Ada® in Practice started lifeas a case studies report, the result of work per formed under government contract at SofTech, Inc. as part of an effort to identify and resolve issues related to Ada usage. Although that report has now evolved into a book intended for a more general audience, its objectives are largely unchanged. Asbefore,the primary goal is to promote effective use of Ada, both in general programming and design practice and in embedded computer systems specifically. Many features of Ada will be new to pro grammers and designers familiar with other languages; the program examples presented in the case studies are intended to serve as guidelines for proper usage of such features while pointing out common misconceptions and programming errors. In addition, we hope that this book as a whole will highlight the advan tages of using Ada at all stages of a program's life cycle, from problem analysis through testing and maintenance. However, it does not purport to hold all the answers to questions ofAda application;areas that would benefit from further investigation or more definitive guidelines are also suggested.
This the fifth issue of the annual publication organized by ADA UK. The intended audience includes managers (needing contact addresses and access to information about ADA products), software and systems engineers using ADA or those intending to use it, requiring detailed technical information about the language. Moreover, those readers new to ADA will be able to gain useful insights about the language and its evolution.
