3 Terms and Definitions
What is defined in GB/T 12905 and GB/T 31866, and the following terms and definitions are applicable to this document.
3.1 Middleware
c) Log file management: manage log files, including log name, size of single log file, and number of log files, etc.;
d) Log output mode management: manage the log output mode, including output to the console, files, and database, etc.
6.1.2 Authority control
The main functions of authority control include:
a) Authority model: subject, resources, authority, role, and role-authority relationship, and subject-role relationship;
b) Resource management: perform unified management and control of the
services provided by the Ecode identification middleware in the form of resources, including resource name and access address;
c) Authentication and authorization: authenticate the identity of the user; after passing the identity authentication, the user has the right to access resources. 6.1.3 Security management
The main functions of security management include:
a) Security audit: audit important user behaviors and abnormal use of system resources. The audit content includes date and time, type, subject
identification, object sensitive marking and event results, etc.;
b) Communication integrity: the communication between the middleware of the Ecode identification platform and application programs supports the
transaction transmission mechanism. When the data transmission is
abnormally interrupted, the transaction is rolled back and re-transmitted, so as to ensure the integrity of the data;
c) Access control: restrict the concurrent access of users and set the number of accesses within the unit time.
6.1.4 Abnormality alarm
The main functions of abnormality alarm include:
a) Equipment operating status alarm: monitor the working status of the hardware equipment linked to the equipment management module; provide alarm
prompts for hardware equipment with abnormal working status;
b) Abnormal data alarm: provide alarm prompts for abnormal data and duplicate data collected and transmitted by the middleware of Ecode identification; The message conveying module mainly conveys messages between the application interface module and the data processing module. Its main functions include: a) Message routing function, which can implement two-way message routing and accurately locate the data processing module and application program that need to be addressed;
b) Message jitter function. There are circumstances where the message
conveying module handles repeated message submission and delivery;
c) Message conveying assurance function. The upper and lower layers of the message conveying module agree on the message reception standards and
ensure that two-way messages can be accurately received;
d) Message retry function: re-send unsuccessfully delivered messages.
6.2.4 Application interface
The application interface module provides access interfaces for application programs that access the middleware. Its main functions include:
a) View access interface, which provides data access interfaces to application programs in the form of data views;
b) Service access interface, which provides data access interfaces to application programs in the form of publishing data as services;
c) Monitoring and management interface, which provides interfaces to
application programs to monitor and manage the middleware runtime services. 6.3 Application Development Subsystem
6.3.1 Development interface
Provide application development interfaces in C, C ++, C # and java language. 6.3.2 Development tools
Support middleware integrated development in development environments, such as: eclipse, idea and visual studio, etc.
6.3.3 Development environment
Support development in development environments, such as: windows, Linux, centos and ubuntu, etc.
