Introduction
GB/T 16656 is a national standard for computer interpretable representation and exchange of product data. Its purpose is to provide an independent
It is a neutral mechanism for any specific system to describe product data throughout the product life cycle. The nature of this description makes it suitable not only for neutral texts
software exchange and is suitable as a basis for implementing and sharing product databases and archives.
GB/T 16656 "Data Expression and Exchange of Industrial Automation Systems and Integrated Products" is a standard composed of multiple parts.
Published separately. GB/T 16656 consists of the following series.
---Parts 1 to 19 describe the method;
---Implementation methods of Parts 20 to 29;
---Parts 30 to 39 conformance testing methods and framework;
---Parts 40 to 59 integrate common resources;
---Parts 100 to.199 integrated application resources;
---Parts.200 to 299 Application Agreement;
---Parts 300 to 399 Abstract Test Suite;
---Parts 400 to 499 application modules;
---Parts 500 to 599 apply explanation construction;
---Parts 1000 to.1999 application modules.
This document belongs to the implementation method series. It specifies standard numbers for data described using GB/T 16656.11 (EXPRESS language)
Data Access Interface (SDAI). Some of the operations defined enable application programmers to operate based on EXPRESS language definitions through this interface.
Data in one or more schemas. Standardization of data access interfaces and data definitions facilitates integration of software from different vendors
components.
The main contents of this document are as follows.
---Chapter 6 to 9.SDAI environment structure defined using EXPRESS language;
---Chapter 10 to 12.SDAI operations, errors and status;
---Chapter 13.Consistency implementation level required for SDAI function implementation.
Computer application systems are implemented using computing languages. Functions defined in this document in a specific computing language may also be called
SDAI language binding. Since there are many computing languages, there are also many SDAI language bindings. SDAI language binding rules
Determined in other parts of the GB/T 16656 implementation method series.
The SDAI language does not need to support the complete set of feature bindings specified in this document to run, and specific feature sets are divided into implementation classes. symbol

Part 22.Implementation Method. Standard Data Access Interface
1 Scope
This document specifies the functional characteristics of the data access interface. This interface is called the Standard Data Access Interface (SDAI). SDAI stipulates
Application operations that can be used to obtain and process data. The structure of these data is expressed in GB/T 16656.11 (EXPRESS language).
Canonical SDAI is independent of any computing language or system. A functional specification defined by SDAI in a specific computing language is called
SDAI language binding. SDAI language binding items are specified in the implementation method series of GB/T 16656.
The following are within the scope of this document.
---Access and process instances of entities described using the EXPRESS data specification language;
---Access multiple databases by a single application at the same time;
---Ensure that the application capabilities of group operations can be saved or canceled according to the needs of the application;
---The application processes its data by reading the dictionary describing the data elements;
---Be able to call the constraints specified by the EXPRESS language according to the application's judgment for verification;
---Support management of dependencies between entity instances;
---Describe the functions of logical collections of entity instances. These entity collections define the total set of entity instances that are allowed to reference entity instances;
---Describe the function of a logical collection of entity instances that define the total set of global verification rules;
---Supports the use of data created by one of the other schemas in a related environment.
The following are outside the scope of this document.
---Complete behavioral specifications for SDAI implementation in multi-user environments;
Note 1.The SDAI implementation does not exclude the possibility of providing multi-user data sharing access, and the behavior of the implementation depends on the underlying data storage technology.
---Specific support for establishing a connection with a remote data repository;
Note 2.It is not excluded that the SDAI implementation provides access to the remote data repository through some other mechanism.
---Data access and processing for data semantics;
---Specify the mechanism or format for saving data in the data resource library;
---Create, delete and name available data resource libraries through SDAI.
