Data Warehouse Design
Data Warehouse Design
As a data warehouse product manager responsible for integrating new data sources into a four-tier medallion architecture, use this decision tree to identify the most effective integration strategy. The tool assumes three guiding principles: all data consumption occurs from the final data products layer; the further right the integration point (towards Platinum), the more efficient the processing in terms of storage and compute; and we prefer materialised views over additional storage layers wherever the source system supports it.
How should I respond to a data quality issue?
How should I respond to a data quality issue?
Determine the appropriate response when a data quality issue is discovered in a pipeline, dataset, or report. This tree helps data engineers and analysts triage severity, decide whether to halt or continue processing, and escalate correctly based on impact and regulatory exposure.
Should I use machine learning or rule-based logic for this problem?
Should I use machine learning or rule-based logic for this problem?
Decide whether your prediction or classification problem calls for hand-crafted rules, a classical ML model, deep learning, or a pre-built AI API. Answering questions about your data volume, explainability needs, and problem complexity will surface the approach with the best effort-to-value ratio.
Which BI and analytics tool should I choose?
Which BI and analytics tool should I choose?
Select the right business intelligence or analytics tool for your team's technical profile, cloud environment, and operational constraints. This tree weighs skill level, hosting preferences, and the importance of a governed semantic layer to surface the best-fit platform.
Which data storage tier should I use for this dataset?
Which data storage tier should I use for this dataset?
Determine the appropriate storage tier for a dataset based on access patterns, latency requirements, age, regulatory obligations, and cost sensitivity. The right tier balances data availability against infrastructure spend and compliance risk.
Which data visualisation type should I use?
Which data visualisation type should I use?
Quickly identify the most effective chart or visualisation type for your dataset. Answer questions about your data's shape, what story you want to tell, and whether geography plays a role to narrow down to the best option.

How to use these trees

  1. Run one to see how the questions are ordered and where each path ends.
  2. Copy the source. Every tree is plain text, so you can lift it and edit the wording for your own organisation. Syntax reference →
  3. Embed it in your wiki, help centre, or intranet with one snippet that stays current whenever you edit the tree. Embedding guide →
