The document describes a case study for a master data management mobile application developed for an IT services client. The app enables managing customer data entities and relationships, searching for and connecting with customers, and allowing sales representatives to find customers. It required integrating with external data sources, providing geo-location search, and handling massive data volumes without performance issues. The app was built using Xcode, Core Data, SQLite, iOS SDK 5.1, and the Graphkit library to display hierarchical data. It took 5 months to fully develop the featured iPad application.

Client is a leading systems integration company that offers a variety of services spanning all the
industry verticals. Client required an iPad application for an effective master data management in
order to keep the enterprise clean of bad data and increase the corporate efficiency. This app
enables the client’s BU team to work in conjunction with external data in mash-up application.
Client required the following:
• Managing data entities and their relationships
• Connect with customers
o Manage customer details
o View customer’s geo-location
o View updates/news about customers
o Connect via email/phone/Skype etc.
• Enabling sales representatives to find (call/visit) a customer
• Search for customers in the current or nearby location (using geo-fencing technology)
• Facility to add new data or update the existing data while on the go
• Comprehensive search, location-based search etc.
• Managing massive data without compromising on the performance
Client Requirement
Project Challenges
Team faced the following challenges:
• To maintain, update, edit and fetch Core Data objects and attributes due to
the huge structure of database schema during the entire scope of the
application.
• Connecting with the Siperian base hub module to fetch responses.
• Creating generic storyboard layout for the entire screen of the project.
• Integrating 3rd
Party Graphkit library to show tree-like structure.

Technologies Used
Manpower
Planning
The following development approach was adopted to equip the site with numerous
features and functionality mentioned below:
• Introduces high level of server and data fetching technology.
• Research and analysis has been scheduled to get the actual level of output of data which are in
the form of different verticals and business logics.
• Development – High Level Coding Standards has been followed for managing backup data
volume simultaneously synchronization with the server for recent updates.
• Syncing existing and newly available data for backup with our database required specific
attention. This helped in result generation.
• The User Interface Layer which forms the Graphical User Interface of the website.

Development Highlights
This application for iPad is built around objective C and Core Data Framework. The design for each
screen is implemented using the storyboard framework which is newly integrated for iOS 5.0. This
application was also made compatible to iOS SDK 5.1 at a later stage. Almost all the modules are
developed using foundation, core graphics and UIKIT frameworks. All the user interface items are
placed in view controllers using storyboard and all the view controllers are linked with the
controller files project along with the outlets and actions of the UI element. Core Data Framework
is used to maintain and store all the details across the project scope. A third party library called as
Graphkit library is used to implement graphs i.e. a tree-like structure. The site was developed and
fully functional within a span of 5 months.
