摘要：
Aspects of the present invention provide a solution for compiling data. In an embodiment, an input query is received in a first language. The input query is translated to a nested relational algebra (NRA) in the form of a first intermediate representation (IR), wherein the first IR comprises a high-level functional language including algebraic operators. A set of algorithms of the algebraic operators is implemented to compile at least some of the first IR into a second IR, wherein the second IR comprises a data-flow language. At least one of the first IR and the second IR is compiled into a low-level code.
