    Just-in-time binding gives you the most meaningful, up-to-date data the moment you need it.

    Late Binding Data Warehouse

    It All Starts With A Data Warehouse

    Most large healthcare organizations have hundreds of analytics vendors. Without bringing all of their data into an enterprise data warehouse (EDW), reliable and repeatable reporting and analysis is impossible.

    Health Catalyst’s Late-Binding™ Data Warehouse is a revolutionary architectural model for healthcare analytics. When an organization combines an EDW with the power of Late-Binding™, they quickly progress to registries and reporting, population health, and clinical and financial risk modeling.

    Late-Binding™ Architecture

    Data must undergo massive transformations to fit into an enterprise data model. Binding is the process of mapping the data in the EDW from source systems to standardized vocabularies (e.g., SNOMED, RxNorm) and business rules (e.g., length-of-stay definitions, ADT rules) so it can be brought together for analysis.

    The Pitfalls of Early Binding

    Traditional data warehouses try to model the perfect database from the outset, determining in advance every possible business rule and vocabulary set that will be needed.

    This practice, called early binding, is a time-consuming, expensive undertaking. In healthcare, business rules and vocabularies change rapidly – and so do the use the cases that data linked across different source systems can serve. Mappings must be redone again and again as data models shift.

    The Wisdom of Late-Binding™

    Health Catalyst’s Late-Binding™ architecture avoids the consequences of linking data with volatile business rules or vocabularies too early. By waiting to bind data until it’s time to solve an actual clinical or business problem, analysts:

    • Don’t have to make lasting decisions about a data model up front when they can’t see what’s coming down the road in two, three, or five years
    • Quickly adapt to new questions and use cases
    • Have the data they need to perform timely, relevant advanced analytics


    Health Catalyst’s Late-Binding™ architecture has a proven track record of agility and adaptability to new rules, vocabularies, and data content that other designs have not matched.

    Early binding architectures – like those espoused by Bill Inmon, Ralph Kimball, and others – force early data bindings into proprietary enterprise data models. Time has proven early-binding architectures to be inflexible, one-size-fits-all solutions, enforcing a compromised, least-common-denominator warehouse.

    Health Catalyst’s Late-Binding™ architecture avoids wasted time and effort by waiting to bind data until a business case drives it, ensuring data retains its original, undiluted value.

    Success Story

    Read how Indiana University Health, the largest health system in Indiana, determined that only a late-binding data warehouse could meet its needs and used the Health Catalyst Analytics Platform to load 14 billion rows of data into the EDW — fully 10 years of clinical data from across IU Health’s network — in just 90 days.

    The Six Binding Points

    Knowing when and how tightly to bind data to rules and vocabularies is critical to the agility and success – or failure – of a data warehouse. Data in Health Catalyst’s Late-Binding™ Data Warehouse can be bound at six points:

    When data is extracted from source systems and loaded into the EDW, it undergoes almost no transformation. Aside from some minimal data conformance (for example, making sure the patient name field in one Source Mart is structured the same as the patient name field in another), the data is kept as raw as possible in a source system’s natural data models.

    Minimal transformation also helps analysts easily track and catalog data lineage through a single enterprise metadata dictionary.

    Health Catalyst’s Late-Binding™ Principles

    The military, manufacturing, and healthcare organizations that have operated their data warehouses by these principles for more than 20 years continue to deliver an unparalleled track record for proven results.

    1. Minimize remodeling data in the data warehouse until the analytic use case requires it. Leverage the natural data models of the source systems by reflecting much of the same data modeling in the data warehouse.
    2. Delay binding to rules and vocabulary as long as possible until a clear use case requires it.
    3. Earlier binding is appropriate for business rules or vocabularies that change infrequently or that the organization wants to lock down for consistent analytics.
    4. Late binding in the visualization layer is appropriate for what-if scenario analysis.
    5. Retain a record of the changes to vocabulary and rule bindings in the data models of the data warehouse. This will provide a self-contained configuration control history that can be invaluable for conducting retrospective analysis that feeds forecasting and predictive analytics.
