不使用MySQL数据库的五个给力理由_MySQL
首先我们要知道，或许有一项技术存在很多理由让我们可以选择使用它，但是让我们不使用它往往只要有一个理由就足够了。选择一个软件产品同样也是如此。 MySQL数据库虽然应用很广泛，受到大家的青睐，但MySQL数据库也有负面的作用，下面就介绍五个不适用 MySQL数据库的给力理由。
1、MySQL(和PHP搭配之最佳组合)的授权方式
MySQL(和PHP搭配之最佳组合)采用双重授权(Dual Licensed)，它们是GPL和MySQL(和PHP搭配之最佳组合) AB制定的商业许可协议。
如果你在一个遵循GPL的自由(开源)项目中使用MySQL(和PHP搭配之最佳组合)，那么你可以遵循GPL协议使用MySQL(和PHP搭配之最佳组合)。然而，如果你的项目不是在GPL协议下的话，你必须为使用MySQL(和PHP搭配之最佳组合)来支付许可费用，或者你可能因为这个因素而将你的项目改为遵循GPL，那么你需要处理因此带来的更多的支持工作，这有可能会带来成本上的提高。在这种情况下，一些软件发行商可能倾向于选择别的开源数据库，例如遵循BSD授权的PostgreSQL。
2、产品成熟性
到2009年，甲骨文的数据库Oracle(大型网站数据库平台)已经诞生了30周年，而MySQL(和PHP搭配之最佳组合)却连它的一半时间都没有。微软的sql server(WINDOWS平台上强大的数据库平台)仅仅比MySQL(和PHP搭配之最佳组合)大两年，但是sql server(WINDOWS平台上强大的数据库平台)的发布是建立在Sybase的基础上，那时候Sybase已经诞生了6年的时间。至于其他值得关注的开源数据库，PostgreSQL将在2009年达到20岁的生日。虽然MySQL(和PHP搭配之最佳组合)并不是市场上最年轻的数据库，但是却有更多成熟的数据库可供我们选择。
当然，或许这并不是我们拒绝MySQL(和PHP搭配之最佳组合)的一个有说服力的理由，但是对于一些比较守旧的IT经理来说，在为一些关键业务选择平台的时候，平台的成熟性却是必须要考虑的一个因素，在这一点上，MySQL(和PHP搭配之最佳组合)无疑毫无优势。
3、功能设置成熟性
要想在MySQL(和PHP搭配之最佳组合)与其他数据库之间进行一个面面俱到的功能设置对比，并不是一件容易的事情。随着新软件版本的发布或一些补丁的推出，曾经的功能列表可能会迅速变得过时了。而且，有些功能对有的应用程序非常重要，但是对别的应用程序则不一定。
有的时候，一些缺失的功能可以通过别的办法来实现，例如，在MySQL(和PHP搭配之最佳组合) 4.1以前，你可以通过使用join方法来替代子查询的功能。在MySQL(和PHP搭配之最佳组合) 5.0中，大多数关系型数据库所要求的功能已经都具备，但是我们却有理由怀疑这些功能在MySQL(和PHP搭配之最佳组合) 5.0中的成熟性。充其量它们在MySQL(和PHP搭配之最佳组合)中被支持的时间也就一年左右，而在其他关系型数据库中则已经存在了近10年的时间。
4、认证的作用
尽管MySQL(和PHP搭配之最佳组合)也有一个认证培训项目，但是它的培训却要比Oracle(大型网站数据库平台)或MS-SQL相差很远。尽管有的使用MySQL(和PHP搭配之最佳组合)的用户表示，MySQL(和PHP搭配之最佳组合)很容易上手，但是对于具有企业级数据库需求的用户来说，无疑希望员工得到系统、有深度的培训，显然MySQL(和PHP搭配之最佳组合)在这一点上还做得很不够。
一个相关的问题是第三方支持的资格问题，尽管直接来自厂商的支持和服务可以一定程度上减缓这个问题，但是，对于有的企业来说，通过强有力的本地化支持显然更有吸引力。
5、关于可扩展的看法
关于这个理由我把它放在最后一位。在很多业界专家中有一个相当一致的观点：MySQL(和PHP搭配之最佳组合)不能很好的扩展。关于这点可能有很大的分歧，争论的焦点主要集中于水平可扩展性和垂直可扩展性上。MySQL(和PHP搭配之最佳组合)则更倾向于垂直可扩展性。
据我的观察，现在有一个趋势，那些经过正式培训的数据库管理员DBA更倾向于选择一个专有关系数据库，例如Oracle(大型网站数据库平台)。对于一些具有专门数据库管理员的比较大的环境来说，MySQL(和PHP搭配之最佳组合)很难得到宠爱，这时候，关于MySQL(和PHP搭配之最佳组合)是否真的具有良好的可扩展性的争论已经没有意义。
不可否认，MySQL(和PHP搭配之最佳组合)也是一个很好的关系型数据库，或许在技术上它与其他领先的关系数据库相差并不大，或不具有劣势。但是，对于一些企业环境来说，MySQL(和PHP搭配之最佳组合)显然不具有优势。 所以不要盲目随大流，也要根据其功能性能的好坏去选择，对MySQL数据库的选用也不是说一定不好，只是在上面这五点上做的不是很好，其他方面还是值得肯定的。

All software will be opened with WPS, and the exe default opening method will be restored.
Jun 19, 2024 am 01:48 AM
All the software on my friend's computer has been opened using WPS and cannot run normally. All exes cannot be opened, including the task manager, registry, control panel, settings, etc. When opened, all WPS garbled characters appear. This situation cannot be done remotely. The remote software is also an exe, which seems to be unsolvable. Let’s take a look at how 20 operates to restore the computer to normal. This is because the opening method of the exe has been changed to WPS, and you only need to restore the default opening method. Er0 exports the exe registry information on a normal computer and puts it on the website. Because the browser can be opened, please guide your friends to open our website, copy the registry information, create a new text document on the desktop, and save it as [File name: 1.reg; Save type: All files (*.
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.
More than just 3D Gaussian! Latest overview of state-of-the-art 3D reconstruction techniques
Jun 02, 2024 pm 06:57 PM
Written above & The author’s personal understanding is that image-based 3D reconstruction is a challenging task that involves inferring the 3D shape of an object or scene from a set of input images. Learning-based methods have attracted attention for their ability to directly estimate 3D shapes. This review paper focuses on state-of-the-art 3D reconstruction techniques, including generating novel, unseen views. An overview of recent developments in Gaussian splash methods is provided, including input types, model structures, output representations, and training strategies. Unresolved challenges and future directions are also discussed. Given the rapid progress in this field and the numerous opportunities to enhance 3D reconstruction methods, a thorough examination of the algorithm seems crucial. Therefore, this study provides a comprehensive overview of recent advances in Gaussian scattering. (Swipe your thumb up

Revolutionary GPT-4o: Reshaping the human-computer interaction experience
Jun 07, 2024 pm 09:02 PM
The GPT-4o model released by OpenAI is undoubtedly a huge breakthrough, especially in its ability to process multiple input media (text, audio, images) and generate corresponding output. This ability makes human-computer interaction more natural and intuitive, greatly improving the practicality and usability of AI. Several key highlights of GPT-4o include: high scalability, multimedia input and output, further improvements in natural language understanding capabilities, etc. 1. Cross-media input/output: GPT-4o+ can accept any combination of text, audio, and images as input and directly generate output from these media. This breaks the limitation of traditional AI models that only process a single input type, making human-computer interaction more flexible and diverse. This innovation helps power smart assistants
Review! Deep model fusion (LLM/basic model/federated learning/fine-tuning, etc.)
Apr 18, 2024 pm 09:43 PM
In September 23, the paper "DeepModelFusion:ASurvey" was published by the National University of Defense Technology, JD.com and Beijing Institute of Technology. Deep model fusion/merging is an emerging technology that combines the parameters or predictions of multiple deep learning models into a single model. It combines the capabilities of different models to compensate for the biases and errors of individual models for better performance. Deep model fusion on large-scale deep learning models (such as LLM and basic models) faces some challenges, including high computational cost, high-dimensional parameter space, interference between different heterogeneous models, etc. This article divides existing deep model fusion methods into four categories: (1) "Pattern connection", which connects solutions in the weight space through a loss-reducing path to obtain a better initial model fusion
