What Is Middleware?

Middleware is a type of software between application systems and system software. It uses the basic services (functions) provided by the system software to connect to various parts of the application system or different applications on the network. the goal of. At present, it does not have a strict definition, but it generally accepts the definition of IDC: middleware is an independent system software service program. Distributed application software uses this software to share resources between different technologies. The middleware is located at the customer The server operating system manages computing resources and network communications. In this sense, an equation can be used to represent middleware: middleware = platform + communication, which limits the use of middleware only in distributed systems, and also distinguishes it from supporting software and utility software. Come. ^[1]

Middleware is a type of computer software that connects software components and applications. It includes a set of services. To facilitate the interaction of multiple software running on one or more machines over the network. The interoperability provided by the technology drives consistency

Middleware is independent system-level software that connects the operating system layer and the application program layer, standardizes the interfaces provided by different operating systems, unifies the protocols, and shields the details of specific operations. Generally, the middleware provides the following functions:

(1) Early development of middleware

Since middleware needs to shield heterogeneous OS and network protocols in a distributed environment, it must be able to provide communication services in a distributed environment. This communication service is called a platform. IBM's CICS (Certified Internal Control Specialist) is the earliest software with middleware technology ideas and functions, but because CICS is not a product of a distributed environment, people generally regard Tuxedo developed by AT & T Bell Labs in 1984 as the first strictly sense Middleware products: For a long time Tuxedo was only a laboratory product. The commercial promotion after it was acquired by NovelIl was not successful. It was only gradually acquired by BEA in 1995 and it became a real middle Manufacturer. During the same period, IBM's middleware MQSeries and many other middleware products also gradually developed and matured. ^[4]

(1) Transactional middleware

Transactional middleware, also known as transaction management program, is one of the most widely used middleware currently.Its main function is to provide the communication, concurrent access control, transaction control, resource management, security management, load required for online transaction processing Balancing, failback and other necessary services. Transactional middleware supports the concurrent access of a large number of client processes and is extremely scalable. Because transactional middleware has the characteristics of high reliability and strong scalability, it is mainly used in telecommunications, finance, aircraft booking systems, securities and other fields with a large number of customers. ^[3]

1. Integration of middleware and e-commerce.

Intemet is the foundation for the development of e-commerce, allowing merchants to use it to expand their business to any location they can reach. This is inseparable from a large amount of information transmission, and e-commerce uses the browser / server B / S (BrowserJServer) technology to achieve the purpose of a large amount of data processing. ^[2]

SA PXI Middleware SA PXI

The SA PXI application integration suite is part of the SA NEtweaver middleware product. The purpose is to provide a non-SAP system with a platform for other management information systems to interact with the SAP system for data and processes. Because SAP is positioned in the ERP system, the focus is on the enterprise. People, property, and things, but for other professional systems of the company, the functions of SAP cannot be covered and replaced, so there must be such an "interface" to achieve mutual data and business exchange. ^[6]
