Database.get_data(uid)

Gets data corresponding to uid (primary key - user/sender/registration ID). The data is broken down into a dictionary to return as an extra step for integrity.

Database.delete_data(uid)

Deletes data corresponding to uid (primary key).

Database.**`insert_data(uid, uni_id=None, uni_pw=None):

Inserts data into database for a registered user. If credentials are not supposed to be remembered, only user/sender ID is stored.

Database.insert_in_reg(uid)

Hashes uid and inserts registration data accordingly. Inserts two sets due to the primary key relation.

Note

A good idea to keep user-data as in JSON format with the following keys:

  • Registered Users:

    • _id: User ID (Primary Key)
    • uni_id: User's University ID for login (ENCRYPTED)
    • uni_pass: User's University Password for login (ENCRYPTED)

  • In-Registration Users:

    • _id: User ID (Candidate Key)
    • reg_id: User's Registration ID (Candidate Key)
