Requirement Web Services Support. In addition to the robust web services support in Oracle Application Server 10g, Oracle database 10g can take in and release web services. DML and DDL operations can be exposed as web services, and functions within the database can make a web service look like a SQL row source, making it possible for usage of effective SQL tools to examine web service information in combination with non-relational and relational information. Oracle Enterprise Manager 10g boosts Oracle’s assistance for service oriented architectures by handling and keeping an eye on web services and other administrator-defined services, tracking end-to-end efficiency and carrying out origin analysis of issues come acrossOracle Database 10g handles all types of structured, disorganized and semi-structure d details, representing, keeping and querying each in its own ideal method while offering typical access to all by means of SQL and XML Query.

An Oracle database server utilizes memory structures and procedures to access the database and handle.Each circumst ances has its own SGA Users presently linked to an Oracle database share the information in the SGA. For optimum efficiency, the whole SGA must be as big as possible (while still fitting in genuine memory) to save as much information in memory as possible and to reduce disk I/O An Oracle database utilizes memory structures and procedures to access the database and handle.
