RELATIONAL DATABASE
PowerSchool is a relational database which consists of many smaller databases or Tables connected together
Each Table contains specific information related to that Table i.e. the Teachers table contains information about the teachers

RELATIONAL DATABASE
Think of it as a large spider web. Some tables connect directly while others do not.

WHAT ARE POWERSCHOOL TABLES?
The PowerSchool Tables are the “backend” of the database.
They contain all of the information for schools, students, attendance, grades, etc.

POWERSCHOOL TABLE STRUCTURE
The PowerSchool database contains over200 tables (Not all tables are visible through DDE)
Each record in a table is assigned a unique ID number
Tables relate to each other using these unique ID numbers

EXAMPLE 1: STUDENT’S TABLE (001) It contains basic student information -
Name, date of birth, address, phone, gender, custom student fields, etc.

Each table has a unique number which tells PowerSchool which table to use when it retrieves information.
