Since the mid-1980s, the database deployment
model has evolved from dedicated database application servers to client/server
to Internet computing implemented using browser-based clients accessing database
applications.
Oracle introduced many innovative technical features to the database as computing
and deployment models changed (from offering the first distributed database to supporting
the first Java Virtual Machine in the core database engine to enabling grid
computing). Oracle offered support for emerging standards such as XML, important
in deploying a Service-Oriented Architecture (SOA). Table 1-1 presents a short list of
Oracle??™s major product introductions.
