The HP-2100A was selected for a skeletal implementation to study performance parameters further. The DBMS structure, some performance results, and several difficulties encountered are described. The HP-2100A minicomputer did provide “hands-on” experience and more direct control to customize disk access routines. However, there were problems with performance measurement in both environments and the expected advantages of the minicomputer were not wholly realized. A specially constructed hardware timing clock would have improved the ability to measure I/O execution times in the HP-2100A.","PeriodicalId":344026,"journal":{"name":"SIGMINI '78","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1978-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133187460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The technique of language preprocessing is employed:\u0000 The preprocessor translates each DML-statement into an internal form; however, in addition to a mere translation of statements the preprocessor has the function of executing so called 'compile-time tasks', i.e. those subtasks of the evaluation of a DML-statement, which can be done at compile-time already. This processing takes place in the course of program compilation and thus the size of the run-time module as well as execution-times can be reduced. The data base system FADABS is used to illustrate this approach.","PeriodicalId":344026,"journal":{"name":"SIGMINI '78","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1978-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121419175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The typical small business which seeks such a system, however, lacks the technical skills which have characterized computer installations in the past. They also lack the financial resources to establish such a function. As a result, these businesses have turned to systems houses, consultants and the hardware vendors for a “turnkey” approach. “I just want to plug it in and run it” is the typical businessman's comment.\u0000 Unfortunately, that approach is frought with problems. The turnkey vendor does not have the same understanding of the small business as its management has. The vendor may have a “package” which he wants to fit his customer into, rather than fitting the programs to the business. There may be contract problems - and most lawyers for small businesses do not understand the special status of a computer turnkey system. There may be problems in training operators or converting data. And on and on.\u0000 These problems can be avoided. Proper planning and knowing when to get help and from where will go a long way. The purpose of this presentation will be to discuss these problems and solutions in the context of the small business.","PeriodicalId":344026,"journal":{"name":"SIGMINI '78","volume":"724 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1978-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122492407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Information stored in such a system is immediately accessible, under user-configured security controls, by any processor attached to it.\u0000 Such a system can expand by simple accretion, without economic penalty. To obtain more processing throughput, one attaches more processors. To obtain more data storage, one attaches additional disk drives as needed.\u0000 In its practical realization, Attached Processing assumes the form of an Attached Resource Computer. The Attached Resource Computer does not employ a central, controlling host computer. System control is decentralized. Failure oï¾£ any individual processor in the system cannot bring all processing to a halt.
