Its advantages include powerful functions, simple operation, convenient management, reliability and security, and fast operation. , multi-threading, cross-platform, fully networked, stable, etc., it is very suitable for the development of Web sites or other application software in the database back-end. In addition, using many languages, users can write and access MySQL database programs. Mysql database is also open source. Developers are increasingly fond of using Mysql relational database, and its application scope has also been extended. Because of its speed and ease of use, it is also used in the development of database backends for Web sites or application software.
The mysql database has many advantages, such as its easy-to-understand operation, powerful functions, and high information storage capacity. Therefore, it is widely used by people. For mysql database, it is generally mainly used for encoding and querying data, and it is applied to this database in many designs. In this process, we can query and combine conventional data, so When we use the mysql database, we only need to write a small piece of data to achieve the corresponding function. A database is a storage room for data storage, but the data is stored on a computer instead of a real storage room. The data is stored in a fixed format, not disordered. The definition is: a fixed format for a long time. Storage on computer memory that can be shared. Database management mainly includes the establishment of data tables, data storage, modification and addition of data. In order to ensure that the database system can operate normally, the management work carried out by relevant personnel. The establishment of the data table can adjust the data in the data table, recombine and reconstruct the data to ensure the security of the data.
2.3 Basic introduction to HBuilder X
1. The fastest development tools
Due to our geeky nature, HBuilder has also been built by us into the fastest front-end development tool, with innovations in code input methods, optimization of code blocks, integration of emmet, shortcut key syntax design, and mouse-less operation. . . These may not be of interest to low-end programmers, but we enjoy them. HBuilder has a slogan: for geeks, for lazy people, and for you.

It would be a waste of technology to make HTML5 without making an app. And cloud packaging also allows programmers who don’t have a Mac computer to develop iOS applications.
4. Capabilities - HTML5plus Runtime After talking about the tools in functional capabilities, let’s talk about capabilities. HTML5plus Runtime, referred to as 5+ Runtime, is an enhanced web engine running on mobile phones. In addition to supporting standard HTML5, it also supports more extended JS APIs, making the capabilities of JS not inferior to native ones. 5+ Runtime is built into HBuilder and is automatically mounted when the real machine is running and packaged.
5. There were phonegap/Cordova solutions in the industry before, but they had too few built-in js apis. Expanding the apis needed to be developed in native languages. What’s more fatal is that the performance of such solutions was insufficient.
6. 5+ Runtime solves the capability gap between HTML5 and native in three levels.
7. Commonly used APIs – HTML5plus is encapsulated into the cross-platform HTML5plus specification, and the specification is made public at www.HTML5plus.org, and no manufacturer’s private API is used.
8. Including QR code, shake, voice input, map, payment, sharing, file system, address book and other common APIs, which can be easily and simply written, and can be cross-platform .
