Relational model for information and monitoring
Steve Fisher · 2001
The GGF performance architecture[5] does not specify the protocol between the consumer and producer. I would like to restrict this to be any protocol consistent with some chosen data model – that is one data model and any protocol consistent with that model. The chosen data model must have the power to represent all the queries we need to make. LDAP, in common with other hierarchical structures is fine if you know all the queries in advance as you can build your database to answer that question very rapidly. Unfortunately if you fail to anticipate the question getting an answer could be very expensive. The LDAP query language cannot give results based on computation on two different objects in the structure – or, expressed in relational language, there is no join operation. We can take as examples Usage Scenarios 14 and 15 collected by Ruth Aydt[1], for which it is very hard to see how LDAP could be adequate.
