Can someone where I can found DBMS Market Researches? What institutes publish reliable researchs? Gartner, IDC?
Note it's hard for any company to provide reliable research that spans both open-source and non-open-source products. For example, one company I'm familiar with sells a specialized storage appliance that contains postgresql inside, but doesn't tell anyone it's there. Neither Gartner nor IDC nor any other market research group would count it correctly. The best analogy I've heard is market research of breathable gases. Any market research company would happily conclude that that Tobacco Smoke is a far more desirable breathable substance than air. Just look at the revenue numbers: Cigarettes - $48.7 billion in 1997 Cigars - $ 0.9 billion in 1997 Fresh Air - $ 0.0 billion in 1997 So the obvious conclusion is that if you're a business the revenue figures obviously show that best practices in the industry is to use smoke. Absurd, yes; but it seems that's how most corporations pick their databases and operating systems.
