Sequence support operators for an abstract database

摘要

The present invention generally provides methods, systems and articles of manufacture that provide a database query application that allows user to compose an abstract query that includes a sequence operator. In one embodiment, sequence operators are used to specify which data elements, from a sequence of data elements, should be retrieved for an abstract query. In another embodiment, a sequence operator may be used to specify that a condition included in an abstract query should be evaluated against particular data elements of the sequence.
