Many of the data files depend on other files to create a robust Campus Labs data ecosystem. Relationships between files are built on shared identifiers. An identifier that is defined in one file will be referenced in another. For example, the Accounts file creates all accounts for students, instructors, and staff who need to use the systems, each with a unique person identifier. The Enrollments file uses the same person identifiers to assign students to the sections they are taking for a given term. Therefore, it is essential that these identifiers match across files. Pay close attention to how these identifiers are formatted when building the extract scripts. The figure below explains the connections between each file and highlights the related datapoints.
