Reviewing what the EDA package includes

Affiliations: tracks connections between contacts (any person, such as a student or faculty member) and accounts (an organization, such as a College or department).
Relationships: tracks connections between contacts.
Addresses: Contacts can have multiple addresses, including seasonal addresses.
Courses: defines the class that is being offered.
Terms: defines the dates when a Course will be offered.
Course Offerings: defines the course being offered during a specific Term.
Course Connections: connects the Course Offering to a specific Contact.
Program Enrollments: tracks a contact’s enrollment in a program.

Table Driven Trigger Management (TDTM): allows admins to organize triggers to fire in a designated order, turn on/off triggers, and set them to fire synchronously or not.
Administrative Account model: EDA is a student/contact-centric data model that focuses on the organizations a student can be affiliated with using the Affiliation object. EDA introduces a trigger that automatically creates Administrative Accounts if the account field is blank when the contact record is created.
An Administrative account has a 1:1 relationship with the contact. For example, Joe Smith, the contact, would have a primary account called Joe Smith Administrative Account.
Multiple Addresses: trigger that updates the primary address with the appropriate addresses, such as seasonal addresses, work addresses, home addresses, or other addresses.
