Django (/ ˈ dʒ æ ŋ ɡ oʊ / JANG-goh; sometimes stylized as django) [6] is a free and open-source, Python-based web framework that runs on a web server. It follows the model–template–views (MTV) architectural pattern .
It is a text-based template language and thus can be used to generate any markup as well as source code. The Jinja template engine allows customization of tags , [ 3 ] filters (for formatting or transforming values [ 4 ] ), tests (for evaluating conditions [ 4 ] ), and globals . [ 5 ]

It is a common misconception that an identity column will enforce uniqueness; however, this is not the case. If you want to ...
An entity–attribute–value model (EAV) is a data model optimized for the space-efficient storage of sparse—or ad-hoc—property or data values, intended for situations where runtime usage patterns are arbitrary, subject to user variation, or otherwise unforeseeable using a fixed design.

(The phone number is dependent on the doctor, rather than the patient, thus would be better stored in a table of doctors.)
In situations where the number of unique values of a column is far less than the number of rows in the table, column-oriented storage allow significant savings in space through data compression. Columnar storage also allows fast execution of range queries (e.g., show all records where a particular column is between X and Y, or less than X.)
