Microsoft's SQL Server is the most popular database application in China, India, Eastern Europe and Latin America, but its open-source competitor MySQL is gaining ground.
A survey of 400 developers found that more than 50 per cent are running SQL Server, particularly in China and Latin America. MySQL's popularity is growing, however, and is used by 46 per cent of companies, mostly in the Indian market.
Microsoft's Visual Basic programming language is also popular in emerging markets, according to the survey. Latin America and China lead the way, but Visual Basic is less popular in Eastern Europe.
