Title: QueryChain

QueryChain, as the name implies, is a Query that is itself a collection of other queries. It simplifies an execution of multiple queries in a single batch. E.g.:

QueryChain query = new QueryChain();
query.addQuery(new SQLTemplate(Project.class, "delete from project"));
query.addQuery(new SQLTemplate(Project.class, "delete from person"));
query.addQuery(new SQLTemplate(Project.class, "delete from department"));

DataContext context = ...
context.performNonSelectingQuery(query);
