Deal Radar kicks the week off with yet another open source company, but one with rather large aspirations. EnterpriseDB was formed in an attempt to disrupt the three-company (Oracle, IBM, and Microsoft) oligopoly that controls the enterprise database market, of which Oracle owns more than half. The company says that as a result of this oligopoly, the market was exhibiting characteristics such as artificially high prices, strong-arm sales practices and vendor lock-in. EnterpriseDB was formed to provide enterprises with an alternative solution.
