Assignment - Mobile client/server application

Objectives - This assessment item relates to the learning outcome 1, 2, 3 and 4. More specifically to design and implement a complex mobile application.

The objective of this assignment is for students to:

Develop, test and maintain a mobile internet application using an integrated suite of mobile software development tools. More specifically on the client side jQuery Mobile, JavaScript and HTML5 and CSS are used. On the server side we use JavaScript and the node server with various node packages. The Mongo database is used as a data store and that data is also stored locally on the mobile device. Using JavaScript store data in a mongdb database in a mongoDB Atlas cloud server using node express middleware.

Introduction - You are assigned the task of creating a data logger to capture experimental data in a mobile application that stores data in a local database. The app has fields to record scientific data for each of five species of chicken. If a chicken species is selected, a page is shown to record data values for that species. A chicken entry consists of a date and log data. When the Save Log Entry button is pressed these values are saved locally in the devices' localStorage. When the Show Log Entries button is pressed a related page is shown that lists all the date/time and chicken entries. More details of these pages will be given in the attached file.

We will refer to our app as chickenLogs. The specification of this app extends that given in Assignment 1. This app is to be tested using the Safari, FireFox or Chrome browser and tested on an Android or iPhone mobile device.

Client Side HTML / CSS / JavaScript Mobile Application -

You are to implement this app using HTML5, CSS and JQuery Mobile. The app is used by a chicken farmer who the five varieties of chicken on his farm. A number of individual chickens exist for each species and an ID number is used to identify these. For each individual chicken the farmer wishes to record data that can be used to determine how well that chicken performs compared to others.

Images for the page/views required to implement the assignment were given in assignment 1 and are further refined in the following figures. Please note that the illustrations are for reference only, and your actual pages will be based on the CSS style-guide in use on your actual mobile device.

Required Documentation -

You are also to prepare a Word document. Your word document should include an appropriate title page. Your word document should have sections that address the commentary, hardware and software requirements and the financial analysis given below

Plan for a Testing Strategy for your Mobile Web Site -

Your document should:

Review the list of mobile devices, browsers and networks targeted for the mobile web site.
Discuss the selection of mobile browser models, mobile OS's and device manufacturers for your testing process.
Discuss whether testing is required on actual devices and what part emulators/simulators and desktop browsers can play in this process.

Financial Case & Commentary of Application Features -

Your document should:

List the features you successfully implemented and those you were unable to successfully implement; you should describe the problem in a few sentences and also briefly describe anything you attempted to do to get it to work. Your approach to identifying and attempting to fix these bugs may gain you some partial credit for those features you were unable to implement.
A description of any additional functionality you believe would be useful to add to this Website should be included. Explain what the features are and how they would help to improve the Website.
Are there any ethical considerations in making this kind of service available?
Discuss the economic/financial case for the proposed system.

Assume this simple exercise leads you to consider developing a fully-fledged chickenLogs application (that is generalised to handle any kind of log data) with increased functionality. Assume you model 3 cases; one with 10 users, one with 1,000 users and one with 10,000 users.

Assume staff development time is costed at $100/hour. Given how long it has taken you to develop this exercise what do you estimate technical development costs to be in hours? What are the development costs for the 3 models, assuming development time increase by 50% for each of the scenarios?

Database storage costs. If you use the mongdb atlas service to store chickenLogs entries, how much would this cost for your proposed user base, assuming 10 entries per month per employee?

Discuss your marketing campaign for each of the three cases and estimate a cost for each of these.

When do you estimate you break even (costs=revenue) in the 3 scenarios? Comment on the results of this analysis.
