While working on this project, we had to do a lot of field research regarding our use-case especially because it is related to medicines and we were looking to keep it simple and efficient. We also ran into the issue of modeling the schema, so as to produce a normalized and efficient database. There were certain issues with working on technologies like AngularJs and NodeJs especially with functions like aggregation, indexing, and embedding of data, both between frontend and backend. All in all, we as a team learned a lot through these challenges, and are happy to have overcome them and produced an efficient product.
