STC ADDS PUB-AND-SUB TO FLESH OUT EAI SUITE.
Software Technologies Corp says it has filled out a complete
message broker suite for integration enterprise applications with the
addition of a home-grown publish and subscribe module to its DataGate
suite called DataCast. Unlike other publish and subscribe models, STC says DataCast offers integrated IP multicast services, as well as data
transformation. According to Lexington, Massachusetts-based WinterGreen Research Inc, which has published a voluminous tome on the EAI market,
Tibco Software Inc currently leads the publish and subscribe space
with a 57.4% market share in 1998 worth some $17.4m. Talarian Corp is
next with 14.9% ($4.5m) and Level 8 Systems Inc with 6.3% ($1.9m). With
STC saying that DataCast can be unbundled as a standalone publish and
subscribe engine it will be going head to head in competition with
these companies. DataCast tracks the state of every transaction and
doesn't rebroadcast to every subscriber in the event that one or
more don't happening to be listening at the time. STC claims it
now offers synchronous, asynchronous and public and subscribe messaging.
Publish and subscribe is just one segment of an EAI market that has a
varying number of components depending on who is talking. WinterGreen
defines five kinds of engines (including publish and subscribe) in the
message broker space plus a further set of EAI framework components.
STC, other EAI companies and Wall Street brokerage Bear Stearns for
example divide the market up in other ways. STC says it's also
important to bear in mind that 85% to 90% of industry does not use
packaged applications. It believes the EAI market comprises adapters;
queuing and storing mechanisms; business rules and collaboration tools
that match inbound message to the destination package; transaction
processing (STC says its DataGate has its own TP technology or can use
third party work); distributed, multithreaded, multiprocessing
technology; and a graphical environment. This quarter it will add native
DB2-CLI and DB2/400 support for mainframe and AS/400 access.
