An approach is provided for data modeling and code generation. The approach involves, for example, providing a syntax for generating a model representing data and semantics of the data. The approach also involves providing an architecture configured to accept the data according to any of a plurality of data representations. The approach further involves providing a code generator configured to generate computer code to transform the data between the plurality of data representations by using the model as a broker between the plurality of data representations. The code generator preserves the semantics of the data during the transforming of the data.
