PERFORMER
 The employee/ learner / user is
viewed as knowledge seeker
with constantly changing needs
& time frames.
 Online & Offline support
services enable greater set
of knowledge.
 On-demand learning in the
workplace, at the moment of need,
becomes essential.

WAEWAP WAP Services
WAP is a communication protocol that enables wireless mobile devices to have access
to the internet. The main motive behind the development of WAP has been the issue
of mobility. This technology has the ability to access information and services
anywhere anytime regardless of the time and place.
 A Wireless Markup Language adhering to XML.
 A specification of a small browser suitable for a mobile, wireless terminal.
 A framework for wireless telephony application (WTAs).
 A programming model based on the WWW programming model.
 A lightweight communications protocol stack

MOBILE LEARNING TECH. IN RUBBER CULTIVATION SECTOR
Objective
To develop a system to access knowledge based information
from RRII ( Rubber research Institute of India ) by growers,
dealers & extension officers engaged in the section of
rubber cultivation through user end mobile phone.

Simulation Tools for Developing the Application :
 Nokia Mobile Internet Toolkit V4.1
 Nokia WAP Gateway Service V4.0
 Nokia Mobile Browser V4.0
 JRE 1.4.1_02
 My SQL 5.1
 Apache Tomcat Server 6.0
 JSP or ASP. Net
 WML / XHTML script language.

Objective ScreenshotsImplementationSimulation toolsArchitecture
1. Dissemination architecture simulated using Nokia Internet Toolkit v4.1.
2. Online banking helps in transaction between dealers and planters.
3. After manufacturing rubbers, planters communicate with dealers for selling purposes.
4. After marketing of rubbers dealers accomplish the monetary transaction through online
banking.
5. In case of any problem regarding rubber cultivation planters can directly communicate in
real time to the extension officers.
6. This toolkit accesses the web server, which is the combination of Apache Tomcat and
ASP.NET.
7. Mobile controls easily target cell phones, PDAs and over 80 mobile Web devices.
8. Application written just once, and the mobile controls automatically generate WAP/WML,
HTML, or iMode as required by the requesting device.

Database
Coding
DATABASE STORAGE ENGINE
Factors relating the use of database storage engine
 CONCURRENCY
some applications have more granular lock requirements (such as row-level locks) than
others. Choosing the right locking strategy can reduce overhead and therefore help with
overall performance. This area also includes support for capabilities like multi-version
concurrency control.
 TRANSACTION SUPPORT
Not every application needs transactions, but for those that do, there are very well defined
requirements like ACID compliance and more.
 PERFORMANCE AIDS
Includes things like multiple I/O threads for parallel operations, thread concurrency, database
check pointing, bulk insert handling, and more..

DatabaseCoding
DATABASE STORAGE ENGINE
 MEMORY CACHES
Different applications respond better to some memory caching strategies than others, so
while some memory caches are common to all storage engines (like those used for user
connections, MySQL's high-speed Query Cache, etc.), others are uniquely defined only when
a particular storage engine is put in play
 REFERENTIAL INTEGRITY
The need to have the server enforce relational database referential integrity through DDL
defined foreign keys.
 PHYSICAL STORAGE
This involves everything from the overall page size for tables and indexes as well as the
format used for storing data to physical disk.

FUTURE SCOPE
 Location aware of fields , grower and near extension centres.
 Point-and-shoot learning with camera phones and 2D codes .
 Near Field Communications (NFC) for secure online transactions.
 Sensors and accelerometers in mobile devices in behavioural based information.
 Mobile content creation (including user generated content).
 Videos and Voice communication facility for learning in mobile devices.
 Context-aware ubiquitous learning.
 Augmented reality on mobile devices
