JDBC Service provider Oracale JDBC Driver Appl Application programming interface (API) Service provider interface (API) Oracle DB server OracleDB Problem with this model of development API where not based on standard Developers required to understand many different api’s API’s where not available on network/internet which limits there use API’s where fine grained API where not available in well known registry Solution - XML based WS or Web services and SOA API = Public Method signature
