DBeaver Data Modeling and Design Guide

# Chapter 1: Data Modeling Fundamentals in DBeaver

## Introduction to Data Modeling
Data modeling is introduced as the process of abstracting real-world data and information into a logical model, describing the structure, relationships, and constraints of data.

### What is Data Modeling?
Data modeling is a process that abstracts real-world data and information into logical models, used to describe the structure, relationships, and constraints of data.

### The Importance of Data Modeling
- Helps clarify relationships between data, enhancing data management efficiency and accuracy of data usage.
- Can aid in designing optimized database structures, reducing data redundancy and errors.
- Serves as the foundation for database design, providing guidance for system development and maintenance.

### Introduction to Common Data Modeling Tools
In practice, common data modeling tools include:
| Tool Name | Main Function |
|---------------|-------------------------------------------------|
| ERwin | Provides entity-relationship modeling capabilities, supporting various database platforms. |
| PowerDesigner | Supports data modeling, data management, and metadata management. |
| DBeaver | Acts as a database client and also enables data modeling design. |

This is a summary of the content in the data modeling fundamentals chapter. Subsequent chapters will delve into how to perform data modeling, design, and optimization using DBeaver, as well as team collaboration and practical case analyses.
