    摘要: An operation (such as a relational query) may be processed on a processing engine (such as a relational database server) on behalf of a client. A conventional processing involves the delivery of the operation to the processing engine, which executes the entire operation to completion and returns a result data set. It may be more efficient to allocate part of the operation to be performed on the client, but a developer may be unable or unavailable to rewrite the operation in a distributed manner. Instead, the operation may be automatically partitioned into a pre-engine client portion, a processing engine portion, and a client portion, and the instructions of each portion may be automatically allocated respectively to the client, the server, and the client. The partitioning may be adjusted to conserve computing resources, such as bandwidth and storage, and the instructions may be reordered to improve the processing of the operation.

    摘要: A program execution engine that facilitates generic type variance verification is provided. The execution engine receives a program executable in the form of intermediate language (IL). The program executable can be based on code that includes expression(s) with generic type(s) which have been identified as requiring variance verification (e.g., covariance and/or contra-variance). The execution engine includes a variance verification component that dynamically determines whether value(s) associated with the generic type(s) identified as requiring variance verification comply with the particular variance verification requirement. The variance verification component can provide error information (e.g., throw an exception), if the specified variance is not safely compliant. Variance verification can be based on static checking which places the burden on a source language compiler to emit the run-time checks in intermediate language (IL), if run-time checked variance is required. Additionally, language(s) that do not support variance can treat generic type(s) as non-variant.

    摘要: A unique formatting scheme for object-relational mapping allows disparate applications that adopt the scheme to seamlessly access data in disparate relational databases. The formatting scheme contemplates a common format that conveys the mapping information through (i) attributes embedded with code objects, and (ii) an external mapping source. Adoption of the common format can result in several advantages for network-based client-server operations: (i) Software developers can continue programming in their existing languages. (ii) Data servers from various vendors can also continue to be developed and managed in the vendors' core programming languages. (iii) Vendors that employ client applications which have adopted the common format can consistently use various data warehouses without incurring customization costs.

    摘要: Anonymous types for a programming language. Non-denotable anonymous types are types that a compiler generates on behalf of a programmer and can then be used as nominal types. Insofar as anonymous types do not have a name, they can be used only inside a method in which they are created. Additionally, an anonymous type cannot be exposed in any way outside of the method. Syntax to create an anonymous type is useful when employed with a Select operator to generate a result with a particular shape, without the need of having a regular type for it. Anonymous types are expressible such that an expression of that type can be written. Translation of an anonymous type by a compiler generates a nominal class that implements Equals and GetHashCode methods. There is equivalence of anonymous types within the same method, and conversion of an unrealized structural type into structurally compatible nominal type.

    摘要: Architecture that extends existing types including constructed and sealed types using extension methods. Extension methods are static methods that can be invoked using instance method syntax. Extension methods are declared by specifying the keyword “this” as a modifier on the first parameter of the methods. Extension methods have all the capabilities of regular static methods. In addition, once imported, extension methods can be invoked using instance method syntax. Also disclosed are rules for importing extension methods, and extension method invocations. Extension methods are imported through using-namespace-directives. In addition to importing the types contained in a namespace, a using-namespace-directive imports all extension methods in all static classes in the namespace. In effect, imported extension methods appear as additional methods on the types that are given by their first parameter and have lower precedence than regular instance methods.
