Navicat 注册，查看其数据库结构

Navicat是一款流行的开源Navicat 数据库结构如下： 1. Introduction: Navicat is an open-source PostgreSQL database that is used for data analysis, reporting, and ad-hoc查询. It is based on PostgreSQL and is designed to be easy to use and extend. 2. Database Architecture: TheNavicat database is built on top of PostgreSQL, which is a popular open-source database management system (DBMS). TheNavicat database is divided into three main parts: - The PRIMARY DATABASE: This is the core of the database, which contains all the data. - The VIEWS:Navicat views are built using PostgreSQL views, which are a way to view or manipulate data in a specific way. - The PROCEDURES:Navicat procedures are used to create, read, and update views and other data structures. The PRIMARY DATABASE is made up of two types of data: - ROWS: These are the primary data points in the database. - VIEWS:Navicat views are built on top of PRIMARY DATABASE ROWS, allowing you to view or manipulate the data in a specific way. The VIEWS portion of the database contains the actual data that you will use in your analysis or reporting. VIEWS are stored in a separate table, called the VIEWS table. The PROCEDURES portion of the database are used to create, read, and update views and other data structures. PROCEDURES are stored in a separate table, called the PROCEDURES table. 3. Example: To give you an example of how theNavicat database is built, consider the following query: ``` SELECT * FROM PRIMARY DATABASE; ``` This query will return all the PRIMARY DATABASE ROWS. To get a view of the data, you can use the following query: ``` SELECT * FROM VIEWS; ``` This will return all the VIEWS that are based on PRIMARY DATABASE ROWS. ``` SELECT * FROM PROCEDURES; ``` This will return all the PROCEDURES that are based on PRIMARY DATABASE ROWS. 4.Conclusion: Navicat is an open-source PostgreSQL database that is designed to be easy to use and extend. It is built on top of PostgreSQL and divided into three main parts: PRIMARY DATABASE, VIEWS, and PROCEDURES. ROWS are the primary data points in the database and VIEWS are built on top of them. PROCEDURES are used to create, read, and update views and other data structures. To give you an example, the query in the previous example: ``` SELECT * FROM PRIMARY DATABASE; ``` return all the PRIMARY DATABASE ROWS. To get a view of the data, you can use the following query: ``` SELECT * FROM VIEWS; ``` This will return all the VIEWS that are based on PRIMARY DATABASE ROWS. To get a view of the data, you can use the following query: ``` SELECT * FROM VIEWS; ``` This will return all the VIEWS that are based on PRIMARY DATABASE ROWS. I hope this helps you understand how theNavicat database is built and used. Please let me know if you have any other questions.
