Last week as i planned before i spent on time designing UI mock-ups and database tables.The good thing is that the designing process was a collaborative work of my both mentors and myself.They have given constructive feedback on the design and finally helped me to come up with the final design.I have updated my design details on wiki page.While designing i am able to realize some insight into theories of database design as well as UI design.
I identified that there are four sets of UI should be designed.
This is the place where the list of available apps are displayed on the side bar and the user is allowed to launch the app within a HTML iframe by clicking on the icon of the app.This is an usual UI every SMART container may contain.Here my job was to identify the best place to put this UI in the OpenMRS.The place should be appropriate to display patient level health data because every SMART UI app is a patient level application.With the help of my mentor i decided to put this UI at patient dashboard where the access to the dashboard is allowed only after selecting a patient.There the patient object can be received which is necessary to create a record in SMART container helper methods.
Manage Apps at user level UI:
In medical world there are range of peoples who need different types of applications.For example the doctor uses application that related to diagnosis process but this type of applications are not relevant to a patient.So it is better to provide a UI for user to customize the available application at main UI.It is usual to put all the user level setting under My Profile in OpenMRS.According to the normal convention i decided to put the UI for managing SMART apps at user level in a vertical tab under the My Profile page.
|Manage Apps at user level|
manage Apps at seystem level(system wide settings) UI:
Normally it is a convention to allow only administrator to install new modules in OpenMRS.This rule is appropriate for SMART apps also.As SMART mentor Josh said i decided to put the add or remove SMART app UI at admin page.
|Manage app (add/remove)|
UI for installing the Apps:
When the user clicks on the add button on the manage app at admin page, a pop up widow will be displayed.This window will allow user to upload a SMART app manifest or to provide a link to the manifest file.
|Add App UI|
Here the primary data are information about users and the SMART apps.OpenMRS alredy has a user table.The new table should be created for modeling SMART apps.SMART app uses a manifest file to save the information about itself.It is straight forward that there are one to one relationship between app database table and the manifest file.In other words database table is used to save informations in the manifest file.I directly modeled database table using manifest file as a guide and created obvious relationships.

I got selected Google Summer Code 2011 this time.I am very proud to be one of the thousand students who are selected this time for this project.I submitted only one proposal to OpenMRS early as possible and i got good response from the mentors.So i got confident and avoid to submit any more proposals.
OpenMRS is a web based open source enterprise medical recording system completely written using J2EE technology.It is used all over the world specially in developing world where the healthcare is facing resource constraints.
While i was searching on how can i improve my coding skill i realized that contributing an open source project is the best way.I selected couple of organizations including OpenMRS.As time goes i was very comfortable with OpenMRS because they are very active community throughout the year and they have very good system to assist new comers.After joining the community i solved couple of tickets and developed a module called CleaningVoided.During this time my learning curve was very sharply rising.
As Google announced the GSOC program ,i decided to participate in the program and prepared a good proposal for idea "Enabling Smart Apps in OpenMRS ".Finaly i got selected and got a chance to contribute community further.Now i specially thanking the community for their valuable help they provided me to achive this.By the way this is only staring point ,in my view the success of this program is achieved at the end of the program when the people are using my code.
The proposal i submitted can be found here.

Here I am going to post series of small posts about maven.
Maven is a project of Apache foundation which ease the software building process.Now this is the famous project management software widely adapted across the software world.The understanding of the philosophy of the maven and familiarity with this software is essential requirement for programmers.If i tell what is maven in one sentence,maven consists of project object model (pom) ,set of standard template ,project life cycle ,a dependency management system and a logic for executing plugin goals during desired phase of the life cycle .The above feature are constructed as a module on the top of core software this is why each lifestyle event can be customized by plugins.Project Object Model(pom.xml)
This is a XML file representing project setting.When we run the maven in a particular directory the maven scans the directory for this file and do the set up according this file.So it is mandatory for every maven project.Here the overview of the pom.xml file.
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <!-- The Basics --> <groupId>...</groupId> <artifactId>...</artifactId> <version>...</version> <packaging>...</packaging> <dependencies>...</dependencies> <parent>...</parent> <dependencyManagement>...</dependencyManagement> <modules>...</modules> <properties>...</properties> <!-- Build Settings --> <build>...</build> <reporting>...</reporting> <!-- More Project Information --> <name>...</name> <description>...</description> <url>...</url> <inceptionYear>...</inceptionYear> <licenses>...</licenses> <organization>...</organization> <developers>...</developers> <contributors>...</contributors> <!-- Environment Settings --> <issueManagement>...</issueManagement> <ciManagement>...</ciManagement> <mailingLists>...</mailingLists> <scm>...</scm> <prerequisites>...</prerequisites> <repositories>...</repositories> <pluginRepositories>...</pluginRepositories> <distributionManagement>...</distributionManagement> <profiles>...</profiles> </project>
Maven Coordinates is an identifier of the maven project which uniquely represents a maven project.This is used to locate the project artifact when the maven search for the project dependency in local repository.
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.aja.javaexamples</groupId> <artifactId>springIOCExample</artifactId> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> <name>Spring IOC Example</name> </project>
project descried by above minimal POM is located as $M2_REPO/com/ajajavaexamples/springIOCExampl
Usually the groubId represent the company for which the project belongs to and the artifactId uniquely represent the project with in the company .Version is a series number dictate the progress of the project.The package indicates the for example weather it is jar or war project.
Rest of the things will be covered in next post.References:
