There are many domestic operating systems, and I would like to introduce one of them: China Operating System (COS), which is another Chinese domestic operating system with independent intellectual property rights developed based on Linux after Galaxy Kirin and Yunos. It can be widely used in personal computers, smart handheld terminals, set-top boxes, smart home appliances and other fields, with friendly interface, support for a variety of terminals, can run a variety of types of applications, safe and fast and other advantages.
There are also many domestic database management systems, such as the Jincang of the National People's Congress, Dameng Database, Nanda General Database, Shenzhou General Database, etc.
At the end of the 70s of the 20th century, China had just begun to use computers, and the database technology at that time was still in its infancy. During this period, international database companies such as IBM, Oracle, and Sybase were the main players in China's database market. In the 80s of the 20th century, China's informatization construction began to enter a stage of rapid development, and the database market also rose rapidly.
In the 90s of the 20th century, database technology has developed rapidly, and a number of database management systems with independent intellectual property rights have emerged, as well as some important technological innovations. In 1994, the Institute of Computing Technology of the Chinese Academy of Sciences released the "Chinese Relational Database System" (CERN), which is the world's first commercial product to support Chinese relational databases, leading the research and application of domestic Chinese databases.
