2.9 Utility and Diagnostics Classes

The Utility and Diagnostics Classes provide specific kinds of functionality. For example, every DB Access Module contains an instance of a class derived from RWDBPhraseBook, which is a list of SQL phrases in the dialect of a specific database. Classes RWDBMemTable and RWDBTPtrMemTable<T,C> provide ways to store relational data in program memory. See the respective entries for these classes in the Reference Guide.

Table 8 lists and briefly describes the Utility and Diagnostic Classes.
