Separate School model

[Kerry Wang]

Records represent an individual observation of a school, and a school can have multiple observations (e.g. different year data, different sessions). The School model should be split into two models: a School model and a SchoolSession model. Model details below.

School:

• id Primary key, used by database internally
• school_id School ID as assigned by country. There is a chance two schools from two different countries will be assigned the same ID by their respective countries, hence not unique and not used as the primary key.
• country
• school_name
• sector
• school_level
• municipality
• zone
• address
• lon
• lat

SchoolSession:

• id Primary key.
• school Foreign key, points to the School this session belongs to.
• session
• data_year
• total_enrollment
• test_score
• gender_ratio
