HP 3000 Middleware Alvina Nishimoto HP CSY R&D Program Manager
Middleware Drivers • Deployment of distributed applications • Customers want choices in their deployment options. Options include: – OS – DBMS – Application packages Middleware is key to building and integrating distributed application independent of underlying technologies.
Job of Middleware “…make the complex world of distributed processing simpler by using middleware as the consistent intermediary rather than by building distributed programs that must natively communicate with nuts and bolts of all the unique requirements of each distributed resource” IDC
Why HP 3000 Customers Need Middleware? • Makes the development of distributed applications easier • Addresses the IS labor shortage • Exploits the power of the Internet – GUI front end access – Easier access to backend computing resources • Facilitate ability for distributed applications to scale up • Allows HP 3000 to participate in this network computing environment

Evolution in Software Development and the Internet/Intranet Application Re-architecting Application Migration Application "Face Lift" Application development toolkits will shift to support both Internet and Intranet business-strength applications via incorporation of WWW browsers, ORBs and Java-like OO4GLs.
Distributed Applications Typical Transition Approach • Establish new interface architecture • Wrap existing applications • Procure and/or build inventory of components • Integrate and implement new components • Replace wrapped components
Types of Middleware • Desktop Access • Data Access – ODBC – JDBC – Gateways • • • • Remote Procedure Call Message-Oriented Object LDAP
Desktop Access Middleware • Interoperability between client graphical user interfaces and existing applications • Allows new user interface to be added to an existing application with little or no code changes • First step into distributed systems • Means to leverage backend applications with GUIs and internet front-ends • Means to provide better customer service through improved access to backend data

Data Access Middleware • Application to data source synchronous interoperability model • Provides data-oriented API to make requests to read or update data from server-based data sources • Uses either SQL syntax or proprietary database gateway API • Need to build applications that are database independent

Gateways Illustration HP 9000 HP 3000 Systems Systems Non-HP Systems (IBM, DEC, SUN, ...
Extraction/Transformation/ Transport Middleware • Used for decision support systems (DSS) and integration • Does reformatting, syntax conversion, and has prebuilt transformations • Content-based, rules-based driven transformation • Real-time or bulk load API
Remote Procedure Call Middleware • Application to application synchronous interoperability for procedural languages • Applications ship a direct call for the execution of a procedure within a remote application • Widely associated with DCE • Trend to bundle RPC with OSs • RPC included in Java as part of RMI

Message-Oriented Middleware • Application to middleware synchronous or asynchronous interoperability • Applications make requests by passing messages directly to the middleware • Messages are records calling for action and supplying the input needed by that action • Event-driven mode of processing, middleware waits for message to invoke the action
