Do Small Projects Also Need Data Structure Design First?

Yes, but it can remain simple. Even with only a few features, the core objects, fields, and relationships should be clearly defined.

Can a Data Structure Be Changed After It Is Finalized?

Yes, but the later changes are made, the wider their impact. Core structures should therefore be confirmed before development begins.

Why Digital Projects Should Define Data Structures Before Designing Interfaces | Miaowang Technology

Interfaces determine what users see, while data structures determine whether a system can operate, scale, and be maintained over the long term.

Many digital projects begin by discussing how pages should look, but whether a system remains stable often depends on the data structure behind the interface.

A data structure must first answer several fundamental questions: What business objects exist in the system? Which fields does each object contain? How are the objects related? What states will the data go through?

For example, an order involves more than an amount and a time. It may also be linked to customers, products, contracts, payment records, and the person in charge. If these relationships are not defined in advance, duplicate data entry and reporting difficulties can easily arise later.

A clear data structure also, in turn, supports interface design. It becomes clearer which information should appear in lists, which actions belong on detail pages, and which states allow editing.

For projects that require long-term iteration, the data structure should also leave reasonable room for expansion, but fields should not be added indefinitely for hypothetical requirements.

Our approach is to first map out objects and processes in business terms, then translate them into a technical model, and finally move on to interface and feature design.
