About the CCC Data Warehouse
The CCC Data Warehouse is developed by the CCC Technology Center (CCCTC) in coordination with, and at the direction of, the CCC Chancellor's Office. A part of the Data Services Program initiative from the California Community Colleges Chancellor's Office, the CCC Data Warehouse provides the necessary infrastructure to the California Community College System to aggregate data from across disparate systems to an enterprise data warehouse.
Direct Access Connection
For authorized researchers at CCC institutions who want to connect local applications to data sources within CCC Data, the CCCTC supports direct access connection to the CCC Data Warehouse as an alternate or additional option to the CCC Data Warehouse (Jaspersoft) Report Server. Local applications at CCC colleges/. Local applications at CCC colleges or districts may include an analytics or business intelligence application such as Tableau or Power BI.

Implementation Process
When a request is received from an authorized individual at a college or district office (often the Dean overseeing institutional research), the CCCTC Enabling Services (ES) team will work directly with the college IT group to configure a custom site-to-site VPN based on the system used by the college. Enabling Services will then establish a secure direct access connection to the CCC Data Warehouse from the college (or district). After successful implementation and query validations, the ES Support team will be able to provide post-implementation (live) support through the CCCTechnology.info support channel.
Process Overview
The process to implement a direct access connection to the CCC Data Warehouse (Redshift) is described below, beginning with a summary of the roles and responsibilities for participants.
Participants, Roles, and Responsibilities
Participant | Is responsible for… |
|---|---|
College/District Researcher |
|
Enabling Services (ES) College Relationship Manager (CEM) |
|
ES Implementation Configuration Engineer (ICE) |
|
College/District IT/Network Admin |
|
ES Implementation Configuration Engineer (ICE) |
|
ES Support Services |
|
| Panel | ||||||
|---|---|---|---|---|---|---|
| ||||||
IMPORTANT: Colleges and districts that use their own analytics/BI applications are responsible for their own support in using those tools. |
...
Request Access
The following are the general steps to establish a direct access connection (ODBC/JDBC) to the CCC Data Warehouse.
...
| Panel | ||||||
|---|---|---|---|---|---|---|
| ||||||
Note: The initial direct connection request should be made to your College Experience Manager. If you do not have the name of the CEM for your college, send an email to cems@ccctechcenter.org. |
...
Establish VPN Configuration
The ES Implementation Configuration Engineer (ICE) works with your primary IT contact(s) to facilitate the configuration of the VPN and to establish the account credentials.
...
| Panel | ||||||
|---|---|---|---|---|---|---|
| ||||||
Note: Ensure that the ES ICE has all necessary system configuration information, including the firewall make, model, and version, as well as IP information. |
...
Establish Account Credentials
In order to access the (Redshift) databases, a service account must be established based on the scope of your authorized access (MIS scope). The ES ICE establishes the service account and provides the account login credentials to the primary IT contact at the college/district. (The login credentials consist of the username and password.)
...
| Panel | ||||||
|---|---|---|---|---|---|---|
| ||||||
Note: The login credentials are a Service Account. While they are issued to an individual, they are intended to be used to connect applications (such as Tableau) to the CCC Data Warehouse. Protecting these credentials is the responsibility of the college/district. |
Scope of Access
Authorized access to the CCC Data Warehouse for colleges and districts using direct access connection (ODBC/JDBC) is permitted through secure login credentials to your local network VPN.
...
| Panel | ||||||
|---|---|---|---|---|---|---|
| ||||||
The <misScope> will appear in the user’s credentials (username) and also in the database schema formats used in SQL queries during the Connect using SQL Workbench validations. |
...
Connect to the Data Warehouse (Redshift Cluster)
This section is designed for authorized colleges who want to gain access to the CCC Data Warehouse Redshift cluster databases. AWS Redshift is a secure, cloud-based data warehouse service used for collecting and storing large-scale data sets and enables users to analyze data using various BI tools.

...
Data Access Validation & Testing
Once connected to the CCC Data Warehouse with your own tool, colleges are encouraged to conduct a series of data access tests and activities, which may include:
...
Using provided user documentation (such as this user guide), the college configures their BI tool to connect to the Data Warehouse.
The college confirms local connection and successful login, and also performs optional data validation activities.
Online documentation is available to support data access validation activities for researchers.
Work with your ES ICE (engineer) to confirm access validation and query tests. Discuss any unfinished implementation steps before hand-off to ES Support.
...
Canvas Data 2 with DW Direct Connect Service
Colleges may request to access their Canvas Data 2 (CD2) data through the CCC Data Warehouse via direct access connection (ODBC/JDBC). The ability to access CD2 data will require the college Canvas Administrator to generate and pass their Canvas Data 2 API credentials to the CCCTC Enabling Services (ES) Implementation Configuration Engineer (ICE) as part of the configuration process. Once received and implemented, the Canvas v2 data warehouse integration will be configured to pass your CD2 data to the CCC Data Warehouse. Following that initial pass, the data will be updated per a configured schedule.
