适用范围：This International Standard provides a generic request/reply-oriented data access mechanismfor applications from independent suppliers to access CIM data in combination withIEC 61970-402: Common Services. An application is expected to use the Generic Data Access(GDA) service as part of an initialisation process or an occasional information synchronizationstep. GDA is generic in that it can be used by an application to access any CIM data. GDA isalso generic in that it also provides a back end storage mechanism independent querycapability that can be used to facilitate the creation of CIM data warehouses.This specification provides a simple, concise service that meets the functionality requirementsof current and future applications while:• avoiding unnecessary complexity;• not requiring any specific database technology for implementation.This service is designed to support interaction where the application or system requestinginformation is developed, supplied, maintained, or operated by a separate agency from theapplication supplying the data. Furthermore, the update portion of this service assumes that itis undesirable for one system to directly write into another1). To support these objectives, theGDA capabilities are divided into three categories:a) read access;b) update access;c) change notification events.It should be noted that the update portion of this service does not support unconditional accessto critical real-time data. Rather, the update portion allows a requesting application to ask fordata to be changed in a service provider, but the service provider is under no obligation tocarry out that change at any particular time. Furthermore, a positive response from the updateservice does not indicate that the update has occurred, but only that the service provider hassuccessfully received the request and that the request is syntactically and semantically correct.GDA could be classified as an Enterprise Information Integration (EII) technology adapterspecialized to the power industry via the assumed use of the CIM. There are a number of EIIproducts currently available on the market, but there is no accepted cross-platform standard forwriting connectors for these products and overall these products do not take full advantage of acommon semantic model such as the CIM. In recommending GDA, WG 13 is recommending astandard EII connector model in the form of a simpler, less expensive, and more specializedinterface.Though the target of this IEC standard includes the utility control center technical domain,generic data access encompasses a general set of concepts that can be applied to many typesof systems. Examples of these systems include:• Energy and distribution management systems• Work and asset management systems• Geographic information systems• Outage management systems• Other types of technically oriented operational business systems.In recognition that the integration between applications in two or more of these systems is oftennecessary, the intent of this specification is to address general GDA requirements to the extentthat they are common to different types of systems while effectively addressing utility operationapplication specific needs.
