Data Model

The data model for the data connector provides data on activity for users in a group across different content types. The currently supported content types are:

Assessments
Assignments
Certification
Courses
Practice
Projects
Tracks
DataLab (formerly Workspace)

How to work with the data?

The data available from the Data Connector is modelled according to a dimensional model. This means there are fact, dimension and bridge tables available.

Facts are the measurements/metrics or facts from your user activity on DataCamp.

course_fact for example contains measures like XP and time_spent on courses by your users.

assessment_fact contains measures like score and percentile for the assessment scores your users have registered on DataCamp.

Dimension provides the context surrounding the fact tables. In simple terms, they give who, what, where of a fact. In other words, a dimension is a window to view information in the facts.

The course_fact table can for example be joined with the course_dim table to find out more information about the courses (like title, technology, instructor, ...) or with user_dim to get information on the users (like email, name, registration date, etc ...)

Bridge tables are used to connect fact and/or dimension tables together. Bridge tables are also referred to as "join tables" in classic SQL.

The user_team_bridge table for example can be used to connect a user to the teams they are member of. In this case a bridge table is needed because a single user can be member of multiple teams at the same time.

You can join the fact tables with the dimension tables to summarize XP and time spent across technology, topic etc.

The data model also provides dimension tables at the user level user_dim, team_dim, group_dim, and bridge tables user_team_bridge to facilitate analysis at the team or user level.

For example, you can aggregate the xp gained and time_spent by week across technology and team with the following query.

SELECT team_id,
       week_start_date,
       technology,
       SUM(xp) AS xp,
       SUM(time_spent)/3600 AS time_spent_hours
  FROM course_fact
       INNER JOIN course_dim USING(course_id)
       INNER JOIN date_dim USING(date_id)
       INNER JOIN user_team_bridge USING(user_id)
       INNER JOIN team_dim USING(team_id)
 GROUP BY 1, 2, 3

from dcdcpy import DataConnector
dc = DataConnector()
(
  dc.course_fact()
    .merge(dc.course_dim(), on='course_id', suffixes=('', '_y'))
    .merge(dc.date_dim(), left_on='date_id', right_on='id')
    .merge(dc.user_team_bridge(), on='user_id')
    .merge(dc.team_dim(), left_on='team_id', right_on='id')
    .groupby(['week_start_date', 'technology'], as_index=False)
    .agg({
        'time_spent': lambda d: d.sum()/3600,
        'xp': 'sum'
    })
)

Warning! The Data Connector's fact tables only include:

learning activity for the dates on which a user was part of the group.
learning activity for the dates on which the group had an active subscription.
learning activity performed by users with all license types, including basic.
learning activity performed in the DataCamp desktop app.

For now, the Data Connector does not include time spent on mobile, this could result in slight differences from other sources of reporting such as exports or our Group Hub.

For example, consider a user A who joined group 1234 on Jan 1st, started a course on Jan 2nd, left the group on Jan 3rd while continuing to work on the course, rejoined the group on Jan 4th, and completed the course on Jan 5th.

In this case, the fact tables for group 1234 will not contain data for User A for January 3rd (even though the user continued working on the course).

Assessments

The Data Connector includes certification and private (test-out) assessments, which differ from standard assessments.

Certification assessments evaluate your knowledge within the Certification process. Private (test-out) assessments are used to skip content within a track if you pass a certain threshold. Reports in the Group Hub do not include certification and private (test-out) assessments. As a result, the reports in the Group hub may show a slight difference in numbers compared to those reported by the Data Connector.
