Optimizing Performance in the Enclave

Learn how best to optimize the performance of your analysis within the N3C Data Enclave. First, gain an overview of Spark, the Enclave's core distributed data processing framework, to gain a mental model of how the data is stored and best accessed. Then, learn about best practices and common issues associated with performance through a discussion, including examples, to demonstrate their impact.

N3C Data Enclave Introduction & Data Use Request (DUR) Process

Get a high-level introduction and overview of the N3C Data Enclave. Learn how to navigate the environment, get acquainted with its underlying organizational structure, view some of the analytical tools available, and see various support options to help you with your journey. The module also provides a brief tour to familiarize users with the data request and access process.

OMOP Vocabulary 201
Take a deeper dive into the OMOP Vocabulary and explore the OMOP common training model's uses in the N3C Data Enclave. This training video is part 2 of the OMOP series, which intends to familiarize users with the vocabulary knowledge they need to better navigate and perform analysis within the Enclave.
OMOP Vocabulary 101

Learn about OMOP and get acquainted with the common data model used in the N3C Data Enclave and its functionality. The training provides an overview using the Athena search function with concept and vocabulary IDs and other standards to facilitate search of the vocabularies and see relationships between other ontologies.

N3C Data Use Request (DUR) Process & Request for Appeal

Learn how to navigate the Data Use Request (DUR) interface in the N3C Data Enclave. View steps to create an appeal to the Data Access Committee's (DAC's) decision by amending initial information submitted to validate required criteria and/or strengthen the rationale for level of data requested.
