CLASSROOM TRAINING

FIELD SUPPORT

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.

PROCESS CONTENTSWAEWAP 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

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

CONCURRENCYsome 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 SUPPORTNot every application needs transactions, but for those that do, there are very well defined requirements like ACID compliance and more.

PERFORMANCE AIDSIncludes things like multiple I/O threads for parallel operations, thread concurrency, database check pointing, bulk insert handling, and more..



DatabaseCoding

DATABASE STORAGE ENGINE

MEMORY CACHESDifferent 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 INTEGRITYThe need to have the server enforce relational database referential integrity through DDL defined foreign keys.

PHYSICAL STORAGEThis 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
