    摘要: A method of building a dataset in a computing system includes extracting data meeting a predetermined criteria from at least a first database, filling the dataset with data items, extracting from the first database relationships between the data items meeting the predetermined criteria, and filling the dataset with the relationships. A system for building a dataset in a computing system includes a data extraction module, a data populating module, a relationship extraction module, and a relationship populating module. The data extraction module extracts data meeting a predetermined criteria from at least a first database. The data populating module fills the dataset with data items. The relationship extraction module extracts from the first database relationships between the data items meeting the predetermined criteria. The relationship populating module fills the dataset with the relationships. A dataset contained within memory of a computing system includes a table component for containing data extracted from a database. The dataset also includes a relations component for containing relationships extracted from the database.

    摘要: Data is separated from source. Datasets store tables of data and a graph of the relationships between the tables. The relationship can change at any time. The relationships are described by metadata that describe primary key, foreign key, and lookups, and other relationships between tables. In one embodiment, the tables of data are typed columns of data. The dataset also includes information on the rowstate and differential preservation, therefore, the source does not need to manage states of the data access. Adapters abstract the interface to datasets. More specifically, adapters manage the input/output to the datasets of the tables of data and the relationships. Adapters can be specialized in their purpose, such as an adapter for OLE data or XML data or generalized in their purpose. Furthermore, a composite adapter is specialized for the purpose of interacting with other adapters. Adapters manage the connection to the dataset and the name of the server that hosts the dataset. Data hoisting is implemented, in which the fluid relationship of data is changed in response to current data needs.

    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.
