摘要: Systems and methods that provide for a canonical representation in a structured form of a query, against a data model platform. A parser component can parse the SQL query to generate the abstract class that represent the query (command tree). Moreover, a view generation component can supply a mapping between a rich structure (e.g., on the client side) and the relational side. Accordingly, a query can be represented by an abstract class in form of a tree structure with nodes, which has metadata tied therewith.
