A table has columnIter. A column has one or more usages. A usage might be a column being used as a foreign key or as part of a measure. <p> Tables are created when calling code requests the set of available tables. This call <code>getTables()</code> causes all tables to be loaded. But a table's columnIter are not loaded until, on a table-by-table basis, a request is made to get the set of columnIter associated with the table. Since, the AggTableManager first attempts table name matches (recognition) most tables do not match, so why load their columnIter. Of course, as a result, there are a host of methods that can throw an <A HREF="http://java.sun.com/javase/6/docs/api/java/sql/SQLException.html" title="class or interface in java.sql"><CODE>SQLException</CODE></A>, rats.<P><P><DL><DT><B>Version:</B></DT> <DD>$Id: //open/mondrian-release/3.0/src/main/mondrian/rolap/aggmatcher/JdbcSchema.java#2 $</DD><DT><B>Author:</B></DT> <DD>Richard M.
