Developing Mobile Enterprise Application Computer Science Essay

Enterprise Mobility is the ability of an endeavor to link to people and command assets from any location. Enterprise mobility includes engineerings like radio webs, nomadic applications, middleware, devices, and security and direction package. It encompasses everything from the integrating of cell phones into an endeavor system to vertically orientated solutions affecting the speedy bringing of productiveness, heightening information to people in the field, the mill, the warehouse, at hard currency registries and at patients ' bedsides.

With Enterprise Mobility in manus, an organisation can profit from improved productiveness, increased client satisfaction, fastened communicating and coaction between employee, client and provider.

The ability to work off from the office and on the move is a defining characteristic of modern concern. No endeavor trusting to stay competitory can disregard the fact that people live in an progressively nomadic universe. From the globetrotting CEO to the nomadic field applied scientist, portable devices such as nomadic phones, laptops and personal digital helpers ( PDAs ) have radically changed the manner people work.

Enterprise Mobility will ensue in significant addition in productiveness ; will supply entree to concern critical information. It is a manner to provide to the work force demands and wants to interact with clients, employees, information, assets and other concerns as and when it chooses.

Enterprise Mobility is deriving credence in Europe, US, Japan, etc.

Apart from basic electronic mail, contact and calendar services being mobilized earlier, the tendency has been changed towards mobilising enterprise assets like CRM, ERP, SCM, and BI etc. More than 80 % of endeavors in the U.

S. , U.K. , France and Germany surveyed by Gartner in 2010 have remote workers, numbering to 50 million nomadic workers worldwide.

Enterprise Mobile Application Development comprises of three development attacks viz. Native Development, Cross Platform Development and Mobile Web Development. Native Development Approach contains nomadic application development for a individual platform like Android, Io, Nokia Qt etc. and is characterized by full device integrating and support. However, with multiple nomadic platforms available today, it is non executable for a SMB to host different squads for each nomadic OS platform. Thus Cross Platform Development plays a important function today, utilizing which a developer could do application and cross compile it into several platform supported application. Mobile Web Application is characterized as an entry-level attack into an organisation 's mobility scheme with restriction of no offline entree.

Examples for different development platforms are enlisted below:

Native Development: Android SDK, Io SDK, Windows Phone 7, Nokia Qt SDK

Cross Platform Development: Rhomobile, Phonegap, Titanium Appcelerator

Mobile Web Development: HTML 5, Doodads, WebKit, Sencha Framework

Given three attacks for application development, it is wholly dependent upon undertaking being developed and on developer 's context. However an organisation can non overlook the benefits of developing natively, upon which it can accomplish high public presentation delivering and bester incorporating application to user 's device.

Unlike Native Development Approach, Cross Platform and Mobile Web Development fail to embrace several critical characteristics of independent development platforms like device 's contact, camera or geo location entree or leveraging each device 's alone set of UI tools and doodads. They besides suffer terrible public presentation hit, unlike native development therefore taking the organisation 's development attack compromised.

Using Native Development Approach, an organisation can drive deep down to the thread degree scheduling, capableness to manage application life rhythm activity, handiness of local storage mechanism and several other benefits. In context to my undertaking for developing, comparing and measuring two humanoids based development platforms, it is imperative that I will utilize native development attack which will offer me greater flexibleness to function the demands and thorough device integrating

.

In early start of twelvemonth 2010, Google announced debut of a DIY tool called Google AppInventor, utilizing which users can make native humanoid applications utilizing Drag & A ; Drop functionality. Based on Scratch ( graphical programming concept of MIT Labs ) , Google AppInventor has become a Ocular Basic of Android Development Platform.

Google AppInventor is poised to be the game Turner in the nomadic application development field with capablenesss of leveraging endeavor development tools with its broad set of available constituents like Web Service Integration, local SQL Lite informations storage, remote destruction and locking etc..

Outline

The undertaking is centric to rating of native application development method for android utilizing Android SDK and Google AppInventor with the aid of a instance survey based on endeavor degree context. The exclusive intent of comparing the application development utilizing GAI and Android SDK is to measure the capableness of Google AppInventor in developing nomadic endeavor application. This will assist mobile developer squads at Patni Computers to calculate the capableness of GAI in doing endeavor nomadic application by leveraging Google AppInventor for fast paced development.

Google AppInventor non merely helps developer to utilize ocular scheduling manner and drag-drop manner but besides helps to minimise clip spent on larning each and every concept that native humanoid SDK offers. The constituents available ease the attempt of developing complex and characteristic rich application.

The attempt while developing precisely same instance survey utilizing native android SDK escalates exponentially, if the developer is naif in the field humanoid nomadic application development. It involves covering with each and every facet of the application being developed which was implicitly managed in GAI.

To develop the comparing between GAI and Android SDK, we have taken instance survey of Employee Directory which encapsulates every facets of a typical nomadic endeavor application like distant entree utilizing web service, offline manner, greater public presentation, security etc.

Employee Directory is an application being developed for the employees of Patni Computers, utilizing which they can seek for any internal forces or group of employee in a Standard Business Unit, anyplace and whenever to eliminate manual storing of each contact of their needed co-workers into their Mobile 's Phone Book and assist them seek the contact inside informations of the needed co-workers on the move. These will assist non merely easier hunt and happen options to the employees but besides render them helpful for non holding to hive away immense sum of members and their contact inside informations which are required merely at given point of clip, given the dynamic nature of an organisation 's work processes.

The user would be able to seek for an employee in an organisation with his name along with options to shop employee register utilizing SBU or Designation. Along with seeking for an employee, a user can besides name, electronic mail, SMS from within the application.

To understand huge Numberss of employees in peculiar organisation, a concept to hive away inside informations of the employee late searched and accessed via the app, in local MySQL Lite database for the easiness of accessing rapidly those who were queried late and often.

Along with this, the undertaking deliverable will besides embrace a characteristic to users to update their nomadic Numberss ( in instance of alterations ) , profile and other contact inside informations which is a most normally encountered state of affairs in any endeavor today. Care would besides be taken to synchronise changed or updated contact inside informations of an employee into the locally stored Recent Logs Database of a user.
