In addition, Oracle offers an alternative Secure Enterprise Search
offering that is more flexible in non-Oracle environments.
Oracle Spatial Option
The Spatial Option is available for Oracle Enterprise Edition. It can optimize the display
and retrieval of data linked to coordinates and is used in the development of
spatial information systems. Several vendors of Geographic Information Systems
(GIS) products now bundle this option and leverage it as their search and retrieval
engine.
XML DB
Oracle added native XML datatype support to the Oracle9i database and XML and
SQL interchangeability for searching. The structured XML object is held natively in
object relational storage meeting the W3C DOM specification. The XPath syntax for
searching in SQL is based on the SQLX group specifications, and XQuery is also
supported.
Database Connection Features
The connection between the client and the database server is a key component of the
overall architecture. The database connection is responsible for supporting all communications
between an application and the data it uses.
