A Sample Page of the Journal  Data Plotting is very simple in MyHealth Journal as shown in figure 8: Figure 8. Data Visualization Approach MyHealth Journal is implemented using java programming language and NetBeans IDE. Some external packages were used especially Mail, JFreeChart, JCalender, and MySQL packages. We designed and implemented the functions shown in Figure 2. Every function was extensively tested. Diverse and complementary test cases were created to cover most possible execution paths.. Figure 2. Hierarchical Task Analysis The following table lists the sub-functionalities in detail: Table 1. List of Functionalities Introduction Important as health is to everyone, and especially to those with conditions to control, most people find it hard to keep a daily record of their health information. Using an old fashioned log is not only inconvenient, but also has the following disadvantages: 1) information is not secure, 2) data is not reproducible, and 3) analysis of long term data may not be straightforward. Figure 1. Old Fashioned Weight Log To avoid having the same shortcomings, before developing the application, we have been talking to potential users and developing different versions of the software in order to decide what functions are most important to the users. Most feedback focused on security of data, usability of the software, and portability of records. In this project, we design and implement MyHealth Journal, a journal software that answers these needs. The software offers a friendly graphical user interface and step by step guidance to help the user get familiar with the product within minutes, data is secure through password protection and encryption, and analysis of long term data is very simple. Abstract Problem : Important as health is to everyone, and especially to those who have conditions to control, most people find it hard to keep a daily log of health information. The fast pace of life and the unavailability of media to record on the go makes it challenging. The old-fashioned hard copy of personal journal is neither convenient nor available enough. Methods : In this project, we design and implement MyHealth Journal, an electronic journal which can be used to record and analyze personal health information to control health conditions. Results : The testing phase proved MyHealth Journal to be fully functional and can be easily used for the daily collection of health information. Conclusion We developed MyHealth Journal, an electronic journal, that allows users to record daily health information in few seconds. The software satisfies most of the needs of the average user in a systematic and efficient approach. The testing phase proved MyHealth Journal to be fully functional and can be easily used for daily information collection.
