Dow Jones


Dow Jones LogoSince 1882, Dow Jones has been finding new ways to bring information to the world’s top business entities. Beginning as a niche news agency in an obscure Wall Street basement, Dow Jones has grown to be a worldwide news and information powerhouse, with prestigious brands including The Wall Street Journal, Dow Jones Newswires, Factiva, Barron’s, MarketWatch, and Financial News.

When Dow Jones decided to build a Caché-based database cache for the next generation of MaketWatch’s Big Charts online graphing solution, they chose J2 to architect and implement it. Over the course of just three weeks, we designed, built, and documented a complete functioning prototype that was handed back to the Dow Jones development team for integration with both the front-end application and the web services from which the source data originates. The cache delivered rapid responses to queries for historical equities pricing data at ten different frequencies, from yearly to minute-by-minute, calling out to multiple web services where necessary to populate or refresh itself.

The Dow Jones project is a great example of J2’s ability to rapidly implement an “80%” solution that can then be transitioned, quickly and painlessly, back to the client for completion by internal resources with little or no prior experience with Caché.
