图表建模指南

Graph modelling is a highly effective technique for representing and analysing complex and interconnected data across various domains. By deciphering relationships between entities, graph modelling can reveal insights that might be otherwise difficult to identify using traditional data modelling approaches. In this article, we will explore what graph modelling is and guide you through a step-by-step process of implementing graph modelling to create a social network graph.

图形建模是一种高效的技术，用于表示和分析各个领域中的复杂和相互关联的数据。通过解密实体之间的关系，图形建模可以揭示出使用传统数据建模方法可能难以识别的见解。在本文中，我们将探讨什么是图形建模，并指导您通过逐步实施图形建模来创建社交网络图。

What is graph modelling?

什么是图建模？

Graph modelling is a method for representing real-world entities and their relationships using nodes, edges, and properties. It employs graph theory, a branch of mathematics that studies graphs, to visualise and analyse the structure and patterns within complex datasets. Common applications of graph modelling include social network analysis, recommendation systems, and biological networks.

图建模是一种使用节点、边缘和属性来表示现实世界实体及其关系的方法。它采用图论，这是研究图形的数学分支，以可视化和分析复杂数据集中的结构和模式。图建模的常见应用包括社交网络分析、推荐系统和生物网络。

Graph modelling process

图建模过程

Step 1: Define your domain

第一步：定义您的领域

Before diving into graph modelling, it’s crucial to have a clear understanding of the domain you’re working with. This involves getting acquainted with the relevant terms, concepts, and relationships that exist in your specific field. To create a social network graph, familiarise yourself with terms like users, friendships, posts, likes, and comments.

在深入研究图形建模之前，了解您正在处理的领域至关重要。这包括熟悉特定领域中存在的相关术语、概念和关系。要创建社交网络图，请熟悉诸如用户、友谊、帖子、喜欢和评论等术语。

Step 2: Identify entities and relationships

第二步：识别实体和关系

After defining your domain, you need to determine the entities (nodes) and relationships (edges) that exist within it. Entities are the primary objects in your domain, while relationships represent how these entities interact with each other. In a social network graph, users are entities, and friendships are relationships.
