  1. EM424 Building Smart-Client Wireless Applications • Alex Reif • Product Manager • iAnywhere Solutions • areif@sybase.com

  2. Introduction to the Wireless Landscape Building Smart-Client Applications Summary Agenda

  3. Commerce Banking, trading Insurance Healthcare Point of care Prescriptions Retail/Hospitality Point of activity ERP Mobile SAP Emerging Mobile Application Areas

  4. Data access at all times Require ‘always available’ applications Enterprise integration Access to various kinds of corporate data Oracle, Sybase, IBM, MS ERP (SAP, PeopleSoft) CRM (Siebel) Increased productivity More efficient data entry Reduce time to market Expectations

  5. Ever-changing wireless environment slows time to market Technical barriers – complex nature of wireless solutions Wireless communications are slow and expensive m-Business Challenges

  6. Challenge: Speed and Cost Thin client mind-set, limited coverage Low bandwidth networks means slow applications Limited battery life for wireless transmissions Challenge: Time To Market Lack of understanding Competitive pressure Challenge: Complexity Connection “stew” Multiple device, network, and security characteristics Emerging, multiple standards The Wireless Challenges iAnywhere SolutionsSolves the Complexity • Unique ‘Always Available’ platformensures fast, reliable accessto information at a lower cost • Experience and proven technology enablesfaster time to market with reduced risk • All major networks, devices, and operating systems • Solution roll-out, optimized 7x24 network center, customer support

  7. iAnywhere Solutions m-Business Platform

  8. Real-world Problemsin Wireless AlwaysAvailable Architecture ProblemsSolved • Faster response/ lower cost • Work anywhere, anytime • Dependability Low bandwidth Coverage andpenetration Battery life • Less datatransferred • Work offline/synch later • Connect when necessary Business Case for Always Available

  9. ‘Always Available’ access to enterprise data Mobile data store Data synchronization Ability to publish content to multiple devices and browsers J2EE Wireless framework Access to Enterprise Data RDBMS, ERP Systems, CRM Systems, mainframe, legacy Security Support for data encryption, authentication and authorization Key Benefits

  10. Application Preview

  11. Smart Client Mobile Data Store Device Identification Data Synchronization Content Transformation Messaging Security Enterprise Integration CRM Mainframe ERP Database Architectural Map

  12. Smart Client Characteristics Development Overview Mobile Data Store Synchronization Messaging Smart Client Development - Topics

  13. Persistent data Mobile data store High-performance data access Data Synchronization Integration with the Enterprise Characteristics of Smart Client

  14. Messaging Push important data to mobile devices Rich user experience Contains business logic Sophisticated User Interface Palm, PocketPC, EPOC, RIM, Java clients Characteristics of Smart Client

  15. Mobile Data Store C/C++ or Java SQL or data access APIs Data Synchronization SQL Messaging C/C++ or Java Rich User Interface C/C++ or Java Development Overview

  16. Proprietary APIs Palm DB, Flat File Custom-coded solutions Customer built data structures, searching, sorting, and synchronization ‘Shrunk-down’ enterprise database Vendor reduces capabilities of enterprise database to make it fit on small devices Other Mobile Data Storage Options

  17. Proprietary APIs One table per ‘database’ Poor performance Limited capabilities Custom-coded solutions Very resource intensive Increased risk Increased maintenance costs ‘Shrunk-down’ enterprise database Pre-chosen limited functionality Architecture not geared for mobile and wireless devices Other Mobile Data Storage Limitations

  18. Advantages of SQL Synchronization to industry standard enterprise databases (robust and secure) Extremely small footprint Hand-coded speed Reduced requirements for platform specific knowledge Mobile Data StoreThe iAnywhere Solution

  19. Step 1: Develop application code Step 2: Invoke Analyzer Step 3: Compile Step 4: Deploy Step 5: Setup Synchronization Mobile Data StoreDevelopment Process

  20. Application Code iAnywhere Analyzer Customized Data Store Compiler Linker Application and Embedded Data Store Mobile Data Store How it Works Reference Database SQL / Data Access Code Runtime Libraries (Data Store)

  21. SQL compliant Referential integrity Transaction processing Multi-table joins Bi-directional cursors Customized for your application Footprint as low as 50K Data structures and algorithms designed for in-memory database Mobile Data StoreFeatures

  22. Performance Support for indexes Pre-optimized queries Large storage capacity Integrated synchronization Mobile Data StoreFeatures

  23. Step 1: Modify GUI Add alert, menu item Step 2: Add data store code Step 3: Add “glue” code Attach data store code to GUI Step 4: Compile/deploy Building the Smart Client Application

  24. Data SynchronizationArchitecture Database Server Synchronization Server Remote Computers

  25. 1. Upload Rows 2. Download Rows 3. Confirm Receipt Data SynchronizationHow it Works ConsolidatedData Store Database Server ODBC SynchronizationServer SmartClient smart

  26. Synchronize to industry standard databases Oracle8, Microsoft SQL Server, IBM DB2 UDB, Sybase ASE, Sybase ASA Synchronization scripts are in native language of the enterprise database Synchronize to other enterprise data sources SAP, Siebel, PeopleSoft etc Accommodated using adapters in server All synchronization is bi-directional Data SynchronizationIntegration Features

  27. The upload_cursor script is used to insert, update, or delete rows in the consolidated database The download_cursor script is used to insert or update rows in the mobile data store Data SynchronizationSimple Example SELECT emp_id, emp_fname, emp_lname FROM employee WHERE emp_id = ? SELECT emp_id, emp_fname, emp_lname FROM employee

  28. Security Built-in authentication 128-bit encryption of communication between client and synchronization server Support for subsetting of data Support for horizontal and vertical partitioning of data Scalable Support for thousands of remote users Data Synchronization Key Features

  29. Conflicts arise when sending data to enterprise database Data Store maintains old value and current value Synchronization server compares old values with consolidated database If old values match there is no conflict If old values do not match there IS a conflict Conflict Resolution Fully customizable by developer Scripts written in native language of enterprise database Can execute stored procedures or user-defined resolutions steps Data SynchronizationConflict Detection Features

  30. Building Smart Client ApplicationsData Synchronization

  31. Store and forward message queuing Guaranteed message delivery Push capabilities Delivery and non-delivery acknowledgements Intelligent (program to program) Messaging Message Delivery

  32. JMS provider for Messaging Server Asynchronous communication from enterprise applications to wireless devices Or between enterprise applications Properties are exposed for communication IP address Server port Provider name Messaging JMS Interface

  33. Networks ARDIS, Mobitex, CDPD, DataTAC, NORCOM, Analog cellular, GSM, CDMA, Wireless LAN Paging networks HDML alerts, email, SMS Devices Palm, PocketPC, DOS, Windows, EPOC, RIM, phone Messaging Services Network and Device Support
