Web Services - Get Transactions and Student-Step Records
status: done, released with DataShop v4.0 December 2009
User Stories
- As a researcher (EDM, M&M, CMDM), I want to retrieve transaction data programmatically and append custom fields to transactions in DataShop so that I can more easily run my models on the data outside of DataShop and put the results back in.
- As a researcher with a machine learning background, I want to retrieve student-step data programmatically so that I can more easily run my analyses on the data without much human intervention.
- As a researcher who has created a custom field for an existing data set, I want to import that new field into the step rollup table so that it is both preserved and available in DataShop tools. - Ryan Baker, 12/15/2008
