Hello, Bob. We need to develop a new research management system. Can you help us with the architecture design?
Bob (系统架构师)
Sure, Alice. First, let's discuss the main functionalities we need to support. What are the core requirements?
Alice
We need to manage projects, researchers, publications, and collaborations. Each project can have multiple researchers, and each researcher can be part of multiple projects. Publications should be linked to specific projects.
Bob
Great. Based on these requirements, I suggest using a microservices architecture. This will allow us to scale individual components independently. For instance, we could have separate services for managing projects, researchers, and publications.
Alice
That sounds good. How about the database design?
Bob
For the database, we can use a relational database like PostgreSQL. We'll have tables for projects, researchers, and publications. The relationships between these entities will be defined through foreign keys. Here’s an example of how the tables might look:
CREATE TABLE projects (
id SERIAL PRIMARY KEY,
name VARCHAR(255) NOT NULL,
description TEXT
);
CREATE TABLE researchers (
id SERIAL PRIMARY KEY,
name VARCHAR(255) NOT NULL,
email VARCHAR(255) UNIQUE NOT NULL
);
CREATE TABLE publications (
id SERIAL PRIMARY KEY,
title VARCHAR(255) NOT NULL,
project_id INTEGER REFERENCES projects(id)
);
]]>
Additionally, we’ll need a many-to-many relationship between projects and researchers. We can achieve this by creating a junction table:
CREATE TABLE project_researcher (
project_id INTEGER REFERENCES projects(id),
researcher_id INTEGER REFERENCES researchers(id),
PRIMARY KEY (project_id, researcher_id)
);
]]>
Finally, we need to ensure that our API endpoints are well-defined and follow RESTful principles. This will make it easier for other systems to interact with ours.
