Are conventional data warehouse vendors in trouble? Probably not, but recent developments and long-standing issues are combining to force dramatic changes in the market.
For starters, data warehousing appliances have game-changing potential. They can cost under $150,000, while conventional solutions cost millions. And vendors claim they can handle enterprise-scale projects.
Another problem for data warehousing is the familiar single-version-of-the-truth issue. Data warehouses typically make their entry into the corporation as single point solutions. Then, when they proliferate, the result can be data chaos.
Database vendor Teradata says the wise enterprise solution is an enterprise data warehouse, both in terms of cost and suitability for the SOA architectures that are likely to dominate enterprise IT in the near future. This argument makes sense, but it's also the kind of "big-bang" approach that many respected consultants are rejecting as too risky.
The data warehousing community is countering these objections by finding new uses for their wares. One example is a recent post in SQL Server Central by data warehousing expert Vincent Rainardi which spells out in great detail how a data warehouse can credibly stand in for a CRM solution.
