Final answer:
To create a business database application, start by identifying criteria and constraints, then design an ER Diagram that considers these factors. Follow this with prototype development, testing, and a detailed design phase to refine the database's physical and functional components.
Step-by-step explanation:
Developing a Database for Business Applications
To develop a database for a business application, it is crucial to first identify criteria and constraints. The requirements are the must-have features of the database, such as specific data fields and functionalities, while constraints are the limitations imposed on the system, like budget or technological restrictions. After initial requirements are gathered, typically through methods like interviewing customers or consulting experts, an ER Diagram is designed to visually represent the database structure.
he ER diagram outlines the entities, relationships, and cardinalities that structure the database, taking into account the requirements and constraints. To ensure the database meets the business's needs, the design process involves multiple steps. It starts with problem identification, proceeds through brainstorming and evaluating potential solutions based on established criteria and constraints, and then selecting a design concept. After a design is selected, a prototype is built, tested, and evaluated, with modifications made as needed based on feedback and testing results.
Only after thorough testing and evaluation does the detailed design phase begin. Here, physical and functional components of the design are more comprehensively defined, including shapes, dimensions, materials, and processes.
