A Methodologic Guide-Line For The Instalation Of Data Base Development Tools And Data Administration Tools: Two Case Studies From Brazil

In this paper we present a systems approach of data administration based upon concepts presented in [1], [2], [3], [4]. The tools herein presented were developed during the case studies described in [4a], [4b]. We divide such tools in five levels and provide interaction between levels by means of a new organizational design called trifunctional scheme. Such case studies are also briefly summarized here. Out of such experiments a methodologic guide-line for the development of tools emerged that is presented in a propositional form.
