Real-time Database system selection

Beijing Hua Heng Letter far has rich foreign mainstream real-time database software implementation experience, according to the actual requirements of the System Integrator project, to provide real-time database selection Consulting, the current domestic and foreign real-time database is divided into four types: a foreign traditional real-time database, foreign configuration software supplier real-time database, The domestic traditional real-time database and the domestic configuration software supplier real-time database, the following respectively describes the above four types of real-time databases:

(1) foreign traditional real-time databases include:
A. OSI Company's PI (Plant information System)
B. Aspen company IP21 (infoplus.21)
C. Honeywell's PhD (Process history Database)
D. InStep Company's Edna (Enterprise distributed Network Architecture)  
Pi in the domestic widely used in the power industry, it uses the rotary door compression patented technology and unique two times filtration technology, so that the data into the PI database has been the most effective compression, greatly saving the hard disk space; IP21 and pi belong to authentic real-time database software, Price and pi is similar, more expensive, IP21 in PetroChina, Sinopec has been widely used; since Honeywell occupies a large portion of the chemical industry's DCs, PhD is used extensively in the chemical industry, and PhD uses Oracle relational databases internally.
The above three kinds of real-time database are launched at the end of the 20 century, the traditional real-time database, because in the power industry occupies a monopoly position of the high PI price, instep Edna by virtue of the price advantage into the power industry, gradually has a certain customer, so the current large power enterprises still prefer the OSI PI, Many small and medium power enterprises have chosen Edna.  
Features: High price, real-time database containing real-time database and other supporting software.

(2) Foreign configuration software vendor real-time database
A. Wonderware Company's historian (formerly Insql)
B. GE Fanuc Company's Ihistorian
C. Rockwell Company's Rssql
D. Siemens Simatic-it-historian
is widely used in the domestic industrial industry due to wonderware configuration software InTouch, especially in the steel industry, As a result, Wonderware Historian (formerly Insql) occupies a large market in the steel industry, and Wonderware Historian internally uses the MS SQL Server relational database, relative to the top three real-time databases, Wonderware Historian into the real-time database market late, relatively easy to learn and use, low prices, the actual project Wonderware historian and InTouch, Aplication server and other wonderware software use. The
GE Fanuc Ihistorian is a real-time database software launched by GE, similar to the Wonderware historian, although the kernel has no relational databases and third-party applications primarily use APIs for data access.
At present the domestic system integrator uses Rockwell Company's Rssql and Siemens Company's Simatic-it-historian is also few, generally is this kind of company in each enterprise Informationization project uses.
Features: Moderate price, but real-time database contains only historical database, real-time database other supporting software (such as Wonderware Idas, InTouch and application, etc.) according to the actual situation of the project need to purchase separately.

(3) Domestic traditional real-time database
A. Beijing Hua Heng Xin Yuan Technology Co., Ltd. EI
B. Beijing and Li Time Information Technology Co., Ltd. Hiris
C. zhejiang Esp-isys Software Technology Co., Ltd.
D. Shanghai Magus Technology Co., Ltd. Openplant
Features: Most of these companies are developing their own real-time database products on the basis of a large number of real-time database engineering implementation experiences and absorbing foreign traditional real-time databases.
Low price, real-time database contains real-time database and other supporting software, because the real-time database market is not as large as the configuration software market, therefore, such products are not widely promoted, is generally the company to do with the real-time database related projects supporting the use of system integrators to purchase the software to do fewer projects, Even if there is a way to cooperate through the project.

(4) Real-time database of domestic configuration software suppliers
A. Beijing Asia control Technology Development Co., Ltd. KINGRDB
B. Beijing three-dimensional force Control Technology Co., Ltd. PSPACE
C. Zijin Bridge Software Technology Co., Ltd. REALDB
Features: Most of these companies are developing real-time database products based on the experience of accumulating configuration software development and application.
Low price, real-time database other supporting software according to the actual situation of the project need to purchase separately. As the company's configuration software market is extensive, customers, and cheap, so the real-time database products developed by such companies are generally relatively inexpensive, but generally such companies do not do their own projects, most of the system integrators buy the software to do the project.
