What a Database Does
A database stores and retrieves structured product information while enforcing selected rules about its shape, identity, and relationships. Define which information is authoritative, who owns it, and what must remain true as it changes.
What You Will Be Able to Decide
- Explain what a database does in product and business terms.
- Apply this decision: Define which information is authoritative, who owns it, and what must remain true as it changes.
- Recognise this material risk: the product's memory becomes inconsistent even though individual screens appear to save successfully.
- Ask a consultant for evidence rather than reassurance.
A founder is deciding how the product should remember information and preserve its meaning over time.
A database stores and retrieves structured product information while enforcing selected rules about its shape, identity, and relationships.
A consultant can recommend and implement the technical approach. The founder still needs to decide which outcome matters, which risk is acceptable, and what evidence is sufficient.
The Founder Situation
A founder is deciding how the product should remember information and preserve its meaning over time.
The immediate question is what a database does. The technical label matters only because it changes a product decision, a responsibility, or the evidence required before launch.
Technical term
What a Database Does
A database stores and retrieves structured product information while enforcing selected rules about its shape, identity, and relationships.
Treat it like a clause in a commercial agreement: its value comes from making expectations and consequences clear, not from sounding formal.
What Matters in Practice
Start with the product consequence, then choose the simplest technical treatment that protects it. A longer tool list is not a stronger plan.
For this decision, the useful standard is that the data model can represent the real business rules without ambiguity or silent corruption.
- Make the decision explicit: Define which information is authoritative, who owns it, and what must remain true as it changes.
- Ask what evidence would show that the chosen approach works.
- Name the person or provider responsible when the approach fails.
- Record the result in the data model and recovery plan.
A Proportionate Decision
Define which information is authoritative, who owns it, and what must remain true as it changes.
The principal risk is that the product's memory becomes inconsistent even though individual screens appear to save successfully. This does not require the most expensive possible solution. It requires the consequence to be understood and the control to match it.
- 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.
Strong Evidence and Weak Reassurance
Warning Signs
- Nobody can explain how what a database does changes a user or business outcome.
- The proposal does not address this risk: the product's memory becomes inconsistent even though individual screens appear to save successfully.
- The only evidence is a successful demonstration of the easiest path.
- The decision has no named owner, boundary, or review point.
- A provider-specific feature is being mistaken for a permanent product requirement.
Questions to Ask a Consultant
- What decision are we making about what a database does?
- Which user or business outcome does the recommendation protect?
- How have we reduced or accepted this risk: the product's memory becomes inconsistent even though individual screens appear to save successfully.
- What evidence can I review without relying on the original implementer?
- What is deliberately deferred, and when will it be reconsidered?
- Who owns the accounts, data, documentation, and recovery process?
Key takeaway
Key Takeaway
A database stores and retrieves structured product information while enforcing selected rules about its shape, identity, and relationships. The founder's job is to make the consequence explicit; the consultant's job is to recommend and demonstrate a proportionate implementation.
