The described implementations relate to updating views in a database system. One implementation can identify an active view that retrieves records from a database and determine one or more physical tables in the database that are referenced by the active view. The implementation can track one or more columns in the physical tables that are used by the active view and identify a change to the physical tables in a transaction log of the database. If the change does not affect the one or more columns, the change can be treated as an ignorable change for the active view.

The subject invention relates to systems and methods that provide null capabilities within the context of programming languages. In one aspect, a system is provided that facilitates null-support in various programming languages. The system includes one or more types associated with at least one programming language. A type modifier is provided to signal that the type is nullable. The type modifier enables a multi-element structure to be automatically created in association with the type wherein, the multi-element structure includes the type and a Boolean element indicating whether or not the variable is null.

General programming language support for nullable types

A blueprint is described that provides a framework for writing a code generator. A blueprint translator translates the blueprint into one or more classes with source code. The newly generated code can then be compiled. If the user wishes to add additional functionality to a generated class, this is done in a separate source file. At compilation time, the compiler combines the generated class with the user's additions, as if they were written in a single class. Later, if the blueprint is ever changed, the generated code can safely be updated without overwriting the user's additions. Alternately, the user can embed his desired additions or changes directly into the blueprint (embedded code). In this manner, should the blueprint ever be re-compiled, the user's changes will still be present. The partial classes technique can be used in conjunction with the embedded code technique.

A music system selects a music library containing multiple music albums, in which each music album contains multiple songs. The system identifies listener preferences associated with a first listener and identifies listener preferences associated with a second listener. A music schedule is generated which contains multiple songs acceptable to both the first listener and the second listener. The music system then plays songs from the music schedule. The listener preferences may include ratings of music albums and ratings of songs contained in the music library.
