Entity Database Model

ADO. NET is the core of. NET interoperability with the database, and the Ado.net entity database enhances the ability of the. NET application to interconnect with the database, and we can easily strongly type data interoperation with the underlying database through the Ado.net Entity Data model. Greatly facilitates the design personnel, thus also enhances the database operation security. A very special problem has recently been encountered when using the domain data service to siverlight [the results in the application are not the same as the results of the database], after repeated experiments, finally found ...

It is well known that cloud OS Windows Azure and Cloud Database SQL Azure play a very important architectural role in Microsoft's cloud computing strategy. Among them, Windows Azure mainly includes three parts, one is the computing service of Operation application, the other is data storage service, the third is the controller (Fabric Controller) that manages and allocates resources dynamically based on cloud platform. And the database plays an important role in the entire Microsoft cloud strategy, especially for cloud database SQL Azure. In other words, SQ ...

Single-table policy: This is the default policy in the inheritance map, which is mapped using this mapping strategy, not specifically specified. The mapping principle for this policy is that the parent class, including the newly added attributes in the subclass, is mapped to a database table, and an automatically generated field in the database table is used to store information that distinguishes the different subclasses. Joined-subclass policy: In this mapping strategy, each entity class in the inheritance relationship, whether specific class (concrete entity) or abstract ...
