    摘要： Multiple programming languages can be embedded and supported within a single source. Programs nested with syntax from a plurality of languages (e.g., C#, SQL, XML . . . ), among other things, enable users to avail themselves of advantageous aspects of different languages for particular tasks. Language services that provide language specific functionality including but not limited to formatting, intelligent assist, auto completion, and coloring, can be employed and switched between to afford support for their respective languages in a mixed language source program. Similarly, mixed language programs can be compiled with language specific services or systems such as parsers, scanners and the like to process corresponding code portions.

    摘要： A database system and method allows a user to write program code in a high-level programming language that implements a class that defines the structure of a user-defined type and methods that can be invoked on instances of the type. The class is then registered with the database system, which enforces a specific contract for user-defined types against the class. The contract comprises the following requirements. First, the class must specify one of a plurality of different formats for persisting instances of the user-defined type in a database store. Second, the class must be capable of returning a null value for the user-defined type. Third, the class must provide a method for converting the user-defined type to another type. Once these requirements are satisfied, the database system enables instances of the user-defined type to be created. A user-defined type can be used in all contexts where any other built-in type can be used. This includes defining columns of tables, declaring variables and parameters to functions and stored procedures, and evaluating expressions of the user-defined type in SQL queries and updates. Preferably, the database system stores metadata about the user-defined type for subsequent use in creating instances of the type.

    摘要： Various embodiments of the present invention are directed to a database with an extensible type system for at least one user-defined type that comprises information for describing its structure as well as information for describing an inheritance relationship between itself and another user-defined type (either a subtype or a supertype/base type). For certain embodiments, the user-defined type is defined in something other than Sequential Query Language (SQL) statement such as, for example, a Common Language Runtime (CLR) statement, a statement in C, C++, and C# (“C-sharp”), and/or a visual basic statement. In any event, several embodiments are further directed to a system wherein the database is aware of the inheritance relationship between two user-defined types by an explicit registration of the user-defined types with said database.

    摘要： The claimed subject matter relates to an architecture that can facilitate an incremental approach to an Object-Relational mapping solution. The architecture can provide a rich data model that is defined at the value layer. The rich data model can expose an interface that conforms with the interfaces exposed by common storage-specific data providers. The architecture can extend common storage-specific data provider to support common command representations, and provide entity services that work in terms of the rich data model as well as object services such as identity management, updating and change tracking.

    摘要： Improved query optimizer using implied predicates. The system facilitates allowing a query optimizing component to introduce into a query, extra predicates that facilitate the following: render the same results as the original query; are used as dictated by rules passed to the optimizing component—these rules specify whether the new predicate is an equivalence (that will substitute the old predicate) or an implication (in which the old predicate is preserved); are considered as cost-based alternatives, and discarded if not useful; are tied to index utilization; and can consider both standard and multi-valued indices.
