....parts of the management information base of a distributed system to be viewed as a single distributed relational database. Our method as depicted in Figure 2 consists of the following steps: Queries about the management information are presented in a standard database query language such as SQL [Sord 84] This query is translated into relational algebra, combined with topological information and optimized. The topological information contains several sections regarding the locations of the underlying agents, tools and tables as well as their properties. Note that one prerequisite for this ....

....a restricted form of data base procedures in a DBMS allows complex data base problems to be easily and naturally addressed. In particular, we propose that a field in a data base be allowed to have a value which is a collection of commands in the query language supported by the DBMS (e.g. SQL [SORD84] or QUEL) Our proposal should augment a field oriented abstract data type (ADT) facility (e.g. ONG84] Such an ADT capability appears useful for supporting relatively simple objects which do not require shared subobjects (e.g. lines, points, complex numbers, etc. On the other hand, data base ....
