Abstract
Embodiments of the invention provide techniques for composing and executing queries using filtered fields. In one embodiment, a query may be composed with compatible fields, meaning filtered fields that store related data of a particular data type. Such compatible fields may be combined into a single query condition, thus simplifying the composition and execution of the query. In one embodiment, fields may be identified as compatible based on metadata included in a database abstraction model.
