I am very new to OpenMrs.Can you please explain what do I have to change?

Before may be i proceed what do you want to develop and achieve ?One thing i know is there are categories of development i.e Module ,Core and RefApp which is more of module development still?

However as far as i understand right now if you do not want to re-invent the wheel, you can communicate with the OpenMRS API /database using the following ways

using

1.Context API to call the services.

2.Rest API.

I urge you to first of all read through the documentations then we proceed from there,if you do not mind.

Can you explain me PersonService personService = Context.getPersonService();
What is context and is getPersonService some method defined by default?

8

The Context is an inbuilt sort Wrapping Object for all sort of service objects,so when you declare it,you can do all staff you want with the underlying API.

So If i want to retrieve data from my table how will I do it?

10

Can you please first read through the documentations?and may be the OpenMRS Data Model can help you have a broader picture of the API.
