Database management system 27″Database Management System: China is still looking for the
“correct way to open it”” (Science and Technology Daily, July 2)
Currently, the two most popular database management systems in the world are Oracle and MySQL,
both products of Oracle Corporation. Competitors include products from IBM and Microsoft. Oracle, IBM,
Microsoft and Teradata are several American companies that account for most of the market share.
Domestic products in database management systems also have market share, but it is only a fraction.
Their stability and performance cannot convince the market. Companies such as banks, telecommunications
, and electric power companies that require extreme stability will not consider domestic products.
SEM 28″Scanning electron microscope has “weak eyesight” and it is difficult to see clearly in industrial
manufacturing” (Science and Technology Daily, July 3)
Scanning electron microscope, a high-end electronic optical instrument, is widely used in various research
fields and industrial sectors such as
materials, biology, medicine, metallurgy, chemistry and semiconductors. It is called a “microscopic camera”
and is currently used by scientific research and industrial sectors in my country. The scanning electron microscopes
used rely heavily on imports. Every year, my country spends more than 100 million US dollars to purchase hundreds
of scanning electron microscopes, mainly
produced in the United States, Japan, Germany, the Czech Republic and other countries. Domestic scanning electron
microscopes only account for about 5%-10%.
