Abstract
A client application may interact with a database service using a data interchange format with limited support for database data types or query representations. A map may be supported in the interchange format as a collection of name-value pairs. A database query may be parsed to form an abstract syntax tree. From the abstract syntax tree, a hierarchy of nested maps may be formed to represent the query, based on schemas mapping from regions of the abstract syntax tree to maps in the interchange format.
