Let’s try a simple scenario where a patient makes an inquiry specifying the doctor's specialization (category) to retrieve a list of doctors that match the specialization. The required information is stored in an H2 database that is shipped with this product.

The client will then communicate with the data service hosted in WSO2 EI to get the required information instead of communicating directly with the back end.
