Abstract

Today's mierp-camputer magazines contain articles which advocate the concept of data base and advertisements for data base management systems Mich run on micro-computers. You would expect these systems to perform similar functions yet their costs vary from $15 to $1500. Why? How do they differ'-:' What functions do *ach' of these advertised data base management systems actually perform? Are they, as some advertisements claim, a solution to everyone's problems? Data integrity, data security, and data independence are important principle objectives of DBMSs. Do UBMSs for micro-computers meet these objectives?

Today's mierp-camputer magazines contain articles which advocate the concept of data base and advertisements for data base management systems Mich run on micro-computers. You would expect these systems to perform similar functions yet their costs vary from $15 to $1500. Why? How do they differ'-:' What functions do *ach' of these advertised data base management systems actually perform? Are they, as some advertisements claim, a solution to everyone's problems? Data integrity, data security, and data independence are important principle objectives of DBMSs. Do UBMSs for micro-computers

Meet these objectives? j~ to answer these quest i cons We, requested information from +orty- eight companies, each of which had adver.tized a DBMS. Our goal was not to criticize or hail systems in reqard to some preconceived DBMS standards, ' but rather to overview each system and compare it with others feature by feature, as documented in their user manuals.

Several companies reacted swiftly with expressions of cooperation and curiosity about our survey results. Other companies reacted negatively. Some companies flatly refused to be inciuded. Meta Jechnology, for example, was too happy with the public's response to their,own DBMS advertising to risk racking the boat with any other type exposure. A total o+*twenty of the original forty-eight companies sent us a user manual and several included a disk.

Individual company responses and the names of the twenty microlcomputer systems we obtained are shown in Chart W. [Table omitted]

Chart 02 lists each of the twenty systems followed by its hardware-requirements, and some general information. The systems are not 14sted in alphabetic order. Instead they are grouped together and listed in the order of the computer an which they rUn, wi th the group representing ,the largest number -of computers listed first. Note that with the exception of CONDOR and MICROCONDUCTOR, alt of the systems which cost more than U50 will run on any of the.popular small computers,'although the speci+ic hardware requirements (for example an S" disk) or an operating system such as CP/M_might rule out the smallest model of that type computer.`
