Recognising Weak Database Design
What must remain true about the business record when people edit, archive, export, or restore it? Review the model using real workflows, failure cases, lifecycle changes, and recovery needs before scaling it.
What You Will Be Able to Decide
- Explain recognising weak database design in product and business terms.
- Apply this decision: Review the model using real workflows, failure cases, lifecycle changes, and recovery needs before scaling it.
- Recognise this material risk: early shortcuts become permanent data ambiguity that cannot be fixed without customer disruption.
- Use this review: Use one CRM contact and its related opportunity to test missing values, duplicate records, deletion, and restore.
A founder is deciding how the product should remember information and preserve its meaning over time. This lesson gives you a concrete question to take into a build brief, proposal review, or product decision.
What must remain true about the business record when people edit, archive, export, or restore it? The course example is A lightweight CRM for a two-person sales team; use it to decide what evidence would justify the choice before a builder implements it.
What Does Recognising Weak Database Design Mean for Your Product?
A founder is deciding how the product should remember information and preserve its meaning over time.
Use the illustrative service for this course (A lightweight CRM for a two-person sales team) to make the choice concrete. What must remain true about the business record when people edit, archive, export, or restore it?
Technical term
Recognising Weak Database Design
Weak database design is visible through ambiguous ownership, duplicated truth, missing constraints, destructive changes, and queries that cannot express product rules safely.
How Should a Founder Use Recognising Weak Database Design?
For a lightweight crm for a two-person sales team, ask what would happen if early shortcuts become permanent data ambiguity that cannot be fixed without customer disruption.
For this decision, the useful standard is that the data model can represent the real business rules without ambiguity or silent corruption.
- Decision: Review the model using real workflows, failure cases, lifecycle changes, and recovery needs before scaling it.
- Evidence to request: show that the data model can represent the real business rules without ambiguity or silent corruption.
- Owner: name who will respond if early shortcuts become permanent data ambiguity that cannot be fixed without customer disruption.
- Record the result in the data model and recovery plan.
- Practical review: Use one CRM contact and its related opportunity to test missing values, duplicate records, deletion, and restore.
How Do You Choose an Approach to Recognising Weak Database Design?
What must remain true about the business record when people edit, archive, export, or restore it? Review the model using real workflows, failure cases, lifecycle changes, and recovery needs before scaling it.
The risk is that early shortcuts become permanent data ambiguity that cannot be fixed without customer disruption. Compare a simpler option with the proposed one, including who will operate either choice.
- Describe the user or business outcome that must be protected.
- Identify the most credible failure and its consequence.
- Compare the simplest adequate approach with one realistic alternative.
- Set a review point for when the decision may need to change.
What Evidence Should You Accept for Recognising Weak Database Design?
What Warning Signs Should You Look For?
- The proposal does not address this risk: early shortcuts become permanent data ambiguity that cannot be fixed without customer disruption.
- Nobody can show whether the data model can represent the real business rules without ambiguity or silent corruption.
- The decision has no named owner or review point.
What Should You Ask a Consultant?
- What changes for the user if we choose this approach to recognising weak database design?
- How have we reduced or accepted this risk: early shortcuts become permanent data ambiguity that cannot be fixed without customer disruption.
- Can you demonstrate that the data model can represent the real business rules without ambiguity or silent corruption?
- Who owns the result, and when will we reconsider it?
Key takeaway
Key Takeaway
Review the model using real workflows, failure cases, lifecycle changes, and recovery needs before scaling it. Ask for evidence against the specific risk: early shortcuts become permanent data ambiguity that cannot be fixed without customer disruption.
