16. Other Mobile Data Storage Options
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

17. Other Mobile Data Storage Limitations

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

20. Mobile Data Store How it Works
Application
Code
Reference
Database
SQL /
Data Access
Code
iAnywhere Analyzer
Compiler
Customized
Data Store
you determine in advance the SQL required by your application
the analyzer generates C/C++ or Java code that implements the SQL in your application
builds a database engine that is specific to your application
the end-result only contains functionality that is required by your application
Linker
Runtime
Libraries
(Data Store)
Application
and Embedded
Data Store

21. Mobile Data Store Features
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

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

23. Building the Smart Client Application
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

24. Data Synchronization Architecture

Server
Synchronization Server
Remote Computers

25. Data Synchronization How it Works
Consolidated Data Store
Database
Server
ODBC
1. Upload Rows
Synchronization Server
Smart Client
2. Download Rows
smart
3. Confirm Receipt

26. Data Synchronization Integration Features
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

27. Data Synchronization Simple Example
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
SELECT emp_id, emp_fname, emp_lname
FROM employee WHERE emp_id = ?
SELECT emp_id, emp_fname, emp_lname
FROM employee

28. Data Synchronization Key Features
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

29. Data Synchronization Conflict Detection Features
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

30. Building Smart Client Applications Data Synchronization

31. Messaging Message Delivery
Store and forward message queuing

Or between enterprise applications
Properties are exposed for communication
IP address
Server port
Provider name
Messages can be used to alert users or to initiate and action, such as data synchronization
Store and Forward: Uses queues on both server and client to store messages when the user is out of coverage or offline; Messages are transparently pushed when the network connection is available
