  <h2>Examples of members</h2>

  <p>Several kinds of members crop up in real life. They all implement the
  <code>Member</code> interface, but tend to be treated differently by the
  back-end system if not by Calcite.</p>

  <p>A member that has zero arguments and a type that is a collection of
  records is referred to as a <i>relation</i>. In schemas backed by a
  relational database, tables and views will appear as relations.</p>

  <p>A member that has one or more arguments and a type that is a collection
  of records is referred to as a <i>parameterized relation</i>. Some relational
  databases support these; for example, Oracle calls them "table
  functions".</p>

  <p>Members may be also more typical of programming-language functions:
  they take zero or more arguments, and return a result of arbitrary type.</p>

  <p>From the above definitions, you can see that a member is a special
  kind of function. This makes sense, because even though it has no
  arguments, it is "evaluated" each time it is used in a query.</p></div>
