212- Agile Modeling

Vocabulary flashcards covering key agile modeling concepts—use case diagrams, data models, screen designs, wireframes, and related database terminology—used to create a shared vision of "done."

Use Case Diagram

A visual model that shows how different users (actors) interact with an application to accomplish tasks, e.g., waiter orders food, chef prepares it.

Data Model

A diagram that outlines how data is organized in relational tables and the relationships between those tables.

Relational Database

A database structure that stores information in tables connected through relationships, typically one-to-many or many-to-many.

Table (Database)

A set of rows and columns in a relational database used to store related records, such as customers or orders.

Field (Column)

An individual attribute within a database table, e.g., customer name, address, or phone number.

One-to-Many Relationship

A database relationship in which a single record in one table (e.g., Customer) is linked to multiple records in another table (e.g., Orders).

Screen Design

A simple, often hand-drawn representation (screenshot) that shows how an application or report should appear to the user.

Wireframe

A low-fidelity prototype composed of successive screens illustrating what appears when specific buttons or links are clicked.

Low Fidelity Prototype

A quick mock-up (no real code) used to validate the look and flow of a product before development begins; synonymous with wireframe.

Low Tech, High Touch

The agile principle of using simple, highly visual artifacts to communicate effectively with stakeholders.

Lightweight (Barely Sufficient) Model

An agile guideline stating that documentation and diagrams should be kept minimal yet adequate for shared understanding.
