Hoover's, the business information company, has released their own Hoover's API, aka "HAPI". This new API enables developers to create applications that utilize Hoover's database of 27 million companies and 34 million business executives (details at our Hoover's API profile). This is certainly useful data for a variety of enterprise applications.
One of the bigger challenges with anything involving APIs is scale. As the number of APIs proliferate, the scalability demands from a management perspective become increasing untenable. Nowhere does that become more apparent than when dealing with mobile computing applications.
