What is it?
IBM's Domino server and Notes client are frequently treated as direct competitors to Microsoft's Exchange Server and Outlook. But while Exchange began as a messaging server, Notes and Domino originated as collaboration and application development platforms. They support calendaring and other groupware functions, but can also be used to develop client/server and web applications, particularly workflow and document-based. This may explain why analysts' figures for IBM's and Microsoft's shares of the messaging market differ so markedly, from giving the two suppliers near-parity, to awarding Microsoft a three-to-one advantage.
In August 2007, IBM announced Notes and Domino Release 8, with a move to the Eclipse development platform. Most Lotus announcements in the last year have concerned "Web 2.0" capabilities - RSS and Atom, representational state transfer (REST) application programming interfaces, mash-ups, social networking. A lot of businesses have been expressing enthusiasm about the potential for Web 2.0 technologies to cut IT costs and improve the quality of collaboration and feedback. Oddly, research by Forrester shows they are less convinced of the benefits of unified messaging, one of the main selling points of Exchange 2007 SP1.
Where did it originate?
Notes began in 1989 as a document-oriented database and workflow application development platform, with replication capabilities which supported collaboration between teams in remote locations and different time zones. IBM took over Lotus in 1995, acquiring Notes at release 4. Domino appeared with Notes 4.5 in 1996
What's it for?
Recent developments include Domino partitioning (running more than one instance on the same server), and Domino clustering for failover and load balancing.
