Serial synchronous communication method for short distances without using modems
Computer program has been developed to calculate and total weights for tubing, fluid in tubing, and weight of fuel cell power source necessary to power pump based on flow rate and pressure drop. Program can be used for fluid systems used in any type of aircraft, spacecraft, trucks, ships, refineries, and chemical processing plants.
The purpose of this manual is to serve as an introduction to the M&DO computer systems and to supplement all other relevant documentation to be referenced. Because of its index structure, the user will be able to reference those sections pertinent to his needs. This is not a programming manual; where a user needs to learn a language or a system, it will be necessary to review the referenced documents.
The installation standards for the (NASIS) data base management system are presented. The standard approach to preparing systems documentation and the program design and coding rules and conventions are outlines. Included are instructions for preparing all major specifications and suggestions for improving the quality and efficency of the programming task.
The system overviews of the NASA Aerospace Safety Information System (NASIS) are presented. The overviews are directed toward informing management of a systems capabilities and requirements. The intent of the overviews contains a description of the component's activities and role in the overall system. The description includes charts and diagrams and discussions of the performance requirements and growth potential of the module.
The data set specifications for the NASA Aerospace Safety Information System (NASIS) are presented. The data set specifications describe the content, format, and medium of communication of every data set required by the system. All relevant information pertinent to a particular data set is prepared in a standard form and centralized in a single document. The format for the data set is provided.
The design specifications for the programs and modules within the NASA Aerospace Safety Information System (NASIS) are presented. The purpose of the design specifications is to standardize the preparation of the specifications and to guide the program design. Each major functional module within the system is a separate entity for documentation purposes. The design specifications contain a description of, and specifications for, all detail processing which occurs in the module. Sub-models, reference tables, and data sets which are common to several modules are documented separately.
The retrieval command subsystem reference manual for the NASA Aerospace Safety Information System (NASIS) is presented. The command subsystem may be operated conversationally or in the batch mode. Retrieval commands are categorized into search-oriented and output-oriented commands. The characteristics of ancillary commands and their application are reported.
The message file for the NASA Aerospace Safety Information System (NASIS) is discussed. The message file contains all the message and term explanations for the system. The data contained in the file can be broken down into three separate sections: (1) global terms, (2) local terms, and (3) system messages. The various terms are defined and their use within the system is explained.
The operation specifications for the NASA Aerospace Safety Information System are presented. The environment which leads to the design, implementation, and installation of the system is described. The manner in which the various components of the system inter-relate is explained. The manner in which the system was installed and subsequently modified is reported.
The Data Base Administrator User's Guide for the NASA Aerospace Safety Information System is presented. The subjects discussed are: (1) multi-terminal tasking, (2) data base executive, (3) utilities, (4) maintenance, (5) terminal support, and (6) retrieval subsystem.
