Data Models

Data Quality Model


This model provides easy-to-use calculations of data quality performance for all HMIS data elements. The fields within this model are strictly associated with the applicable version of the HUD HMIS Data Dictionary for the current fiscal year. Like the HMIS Performance Model, the Data Quality Model is based on project enrollments. For convenience, some of the dimensions from HMIS Performance are included in this model and mirror the structure of HMIS Performance.

This model will immediately reflect changes in Clarity. As corrections to the data are made, those changes will be quickly updated in Looker. As a tradeoff, this model performs a bit slower than some of the other models.

Dimensions and Measures

For most of the DQ HMIS Data Elements dimensions, the error looks for enrollments where the data element has a value of:

  • None - No error found
  • Client doesn't know
  • Client refused
  • Data Not Collected
  • Null

If a dimension looks for other problems, that approach will be described below.

The Measures in each section include counts of each element and some groups of elements.

Agencies - This section contains basic information about the Agency.

Client Services - This section has program service information connected to a client, the record of services received by the client.

Clients - Static demographic fields such as Name, Date of Birth, Social Security Number, Veteran Information, etc.
