Contains some meta information that helps EasyQuery components to build query statements in SQL or other query languages. Any data model contains the following main sections:
QueryExpr class
/api-reference-5x/korzh-easyquery-namespace/queryexpr-classRepresents a sub-query expression
ValueEditor class
/api-reference-5x/korzh-easyquery-namespace/valueeditor-classRepresents an abstract value editor.
