学习、操作心得
以前在做网站程序的时候一直用的是MYSQL，，但是网上搜到MYSQL不支持分布式操作，然后便开始查询MSSQL的分布式数据库的设计与操作，后来在网上找到了《基于SQL SERVER的分布式数据库设计与实现.pdf》文档，认真阅读后对水平分布和垂直分布更加了解了，但是还是没有想到怎样去实现一个同一逻辑但不是同一地域的分布式数据库。
后来有同学在实验课上讲述了怎么去实现同一逻辑但不是同一地域的数据库的连接，这帮我在设计数据库，配置数据库、连接数据库迈出了坚实的一部。
在刚实现连接之后，出现了许多问题，这些问题都在网上搜到了也解决了。
在真正做MSSQL分布式数据库之前只是在SQL Server Management Studio中实现了分布式数据库的一些操作，程序代码是先由MYSQL集中式数据库先写了一遍，操作了一遍，没有问题才将MYSQL的一些代码换成MSSQL的代码。

How does Go language implement the addition, deletion, modification and query operations of the database?
Mar 27, 2024 pm 09:39 PM
Go language is an efficient, concise and easy-to-learn programming language. It is favored by developers because of its advantages in concurrent programming and network programming. In actual development, database operations are an indispensable part. This article will introduce how to use Go language to implement database addition, deletion, modification and query operations. In Go language, we usually use third-party libraries to operate databases, such as commonly used sql packages, gorm, etc. Here we take the sql package as an example to introduce how to implement the addition, deletion, modification and query operations of the database. Assume we are using a MySQL database.
PHP Coding Practices: Refusing Alternatives to Goto Statements
Mar 28, 2024 pm 09:24 PM
PHP Coding Practices: Refusal to Use Alternatives to Goto Statements In recent years, with the continuous updating and iteration of programming languages, programmers have begun to pay more attention to coding specifications and best practices. In PHP programming, the goto statement has existed as a control flow statement for a long time, but in practical applications it often leads to a decrease in the readability and maintainability of the code. This article will share some alternatives to help developers refuse to use goto statements and improve code quality. 1. Why refuse to use goto statement? First, let's think about why
How does Hibernate implement polymorphic mapping?
Apr 17, 2024 pm 12:09 PM
Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.
iOS 18 adds a new 'Recovered' album function to retrieve lost or damaged photos
Jul 18, 2024 am 05:48 AM
Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps
An in-depth analysis of how HTML reads the database
Apr 09, 2024 pm 12:36 PM
HTML cannot read the database directly, but it can be achieved through JavaScript and AJAX. The steps include establishing a database connection, sending a query, processing the response, and updating the page. This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.

Analysis of the basic principles of the MySQL database management system MySQL is a commonly used relational database management system that uses structured query language (SQL) for data storage and management. This article will introduce the basic principles of the MySQL database management system, including database creation, data table design, data addition, deletion, modification, and other operations, and provide specific code examples. 1. Database Creation In MySQL, you first need to create a database instance to store data. The following code can create a file named "my
