Design Considerations for Mobile Enterprise

System Design for All That Glitters Is Gold Jewelry Store, a hybrid mobile app was chosen to support multiple platforms and reuse existing web development skills. The design considerations include cross-platform support, technology growth, high-quality and flexibility. Enterprise applications integrate with data services and require offline application data synchronization, ensuring security, scalability, and maintainability. Mobile apps behave like standard websites but with mobile-specific features, whereas web apps are actual applications downloaded onto the device. Required entities and attributes were identified for a relational database design, including customer, item, shopping cart, order, credit card, e-commerce, shipping, and more.

Design considerations for a mobile app can be either native or hybrid. For the purposes
of this online jewelry store the hybrid option was chosen. It was considered the better choice
because of it better potential for cross-platform support and reuse capabilities of existing web
development skills.
The design considerations for a mobile application are as follows:
 The mobile enterprise can support more than one mobile platform.
 The mobile enterprise can develop and launch more than one mobile application ranging
from 5-20 mobile applications, thereby allowing for technology growth.
 Eliminates the difficulty in finding a qualified team with native development skills,
thereby affecting the time to market of the mobile application.
Hybrid development provides high-quality and the flexibility needed for the mobile application.
Enterprise applications and data service integration support offline application data that is
synchronized to the enterprise database. This ensures that the mobile application is secure,
scalable, and maintainable. The installation of a mobile middleware server or a mobile gateway
sits between the mobile application, the existing application, and data services. All of the mobile
enterprise applications are connected to the middleware server to reduce integration dependency.
From there the mobile applications only need to be authorized to support security. Secure
storage and encryption and end-to-end encryption is needed since the possibility of data leakage
is high with mobile applications. In addition, sensitive data within the mobile device is also
encrypted to minimize data leakage. Other factors to ensure smooth integration and
implementation of the mobile enterprise applications are proper setup of HTTPS is implemented
along with security redundancy; and application log gathering where activity logs are sent back
to a logging server.

Mobile Apps vs. Web Apps
Mobile apps behave much like standard websites do in that they consist of browser-based HTML
pages linked together and accessed over the Internet via Wi-Fi. However, it is designed for the
smaller handheld display and touch-screen interface with mobile-specific features such as click-
to-call or location-based mapping. Web apps are actual applications downloaded and installed
onto the mobile device rather than accessed via an Internet browser. The end user visits device
specific portals called app stores. Some popular examples are Apple’s App Store, Android
Market, or Blackberry App World. The web app can download content from the Internet or
download content to be accessed without the Internet. Each business would need to weigh the
pros and cons to make the important decision in choosing which application meets their business
needs.

Conclusion
The next step in the project progression is to conduct a business requirements review to
ensure that all stakeholders are in agreement with the above blue print outlining the business
requirements discussed. The goal is for the business requirements to be clear, concise, and bring
value to All That Glitters Is Gold Jewelry Store.
