What does it include?

It actually has three levels: the first level is hardware, which mainly refers to the host computer and network communication equipment used for data storage, processing and transmission; The second layer refers to software, including all kinds of software that can be used to collect, store, retrieve, analyze, apply and evaluate information. It includes what we usually call business management software, as well as management software for strengthening process management and software for assisting analysis. The third layer refers to the application, which refers to the collection, storage, retrieval, analysis, application, evaluation and use of all kinds of information, including the application of ERP, CRM, SCM and other software to directly assist decision-making, and also including the use of other decision-making analysis models or the use of DW/DM and other technical means to further improve the analysis quality and assist decision-makers to make decisions (to emphasize one point, it only assists rather than replaces people's decisions). Some people understand that it combines the first two layers into one, which refers to the storage, processing and transmission of information, while the latter refers to the application of information; Some people combine the last two layers into one, which is divided into hard front and soft back. Usually, the third layer has not been paid enough attention, but in fact, only when information is effectively applied can its value be fully exerted and the goal of informatization be truly realized. Informatization is not an end in itself, but a better means to achieve the goal in the current era background.

Sensing technology is the extension and expansion of human sensory organs, the most obvious example is bar code reader;

Communication technology is the extension and expansion of human nervous system, which undertakes the function of transmitting information;

Computer technology This is the extension and expansion of human brain function, and it undertakes the function of processing information.

The so-called informatization is to transform other industries and industries with information technology, so as to improve the efficiency of enterprises. In this process, information technology plays the role of a powerful tool.
