Real-time/historical database * product selection

There are many commercial products in the SIS (factory-level monitoring system) database. When selecting the database, consider the following: ease of maintenance and management of databases, openness and scalability, comprehensiveness of client software functions, Web Support, difficulty of secondary development, support for data types, support for time and multiple time zones, factors such as the degree of support for distributed applications, security control capabilities, fault tolerance capabilities, Chinese characters supported, technical support capabilities of software vendors, and economic and practical needs, select the appropriate product based on the actual situation of the power plant. Typical products at home and abroad are ):
● Pi (process information): the products of OSI, with a high market share, have been implemented by many power plants and metallurgical enterprises in China. The "Screw door" is a proprietary data compression technology of Pi. Its Mathematical mechanism is to use multiple broken lines to fit an approximate continuous curve. Pi includes two categories: server software and client application software. Common customer applications include PI-processbook, Pi-datalink, and Pi-activeview. Pi has rich data interfaces and can provide commercial interface software for the vast majority of well-known control systems. Company website http://www.osisoft.com.
