Web Development Services In Pakistan 5 (4)

Web Development What exactly does web development do? It mainly involves the following aspects: Front-end development Responsible for developing the user interface and interactive parts of the website, including technologies such as HTML, CSS and JavaScript. Back-end development Responsible for processing the data and business logic of the website, including developing web applications using server-side languages (such as PHP, Python, Java, etc.) and using databases to store data. Database management Responsible for designing creating and maintaining the database of web applications to ensure data security reliability and efficiency. Web server management Responsible for installing, configuring and maintaining web server software to ensure that web applications can run properly. The ultimate goal of web development is to create a complete and powerful web application to meet user needs and improve business efficiency. What does web development technology include?

Web development technologies include many types. The following are some commonly used Web development technologies. HTML/CSS HTML is the markup language used to create web pages, and CSS is used to control the style and layout of the page. JavaScript A scripting language used to add interactive and dynamic effects to web pages. Front-end framework For example, React, Angular, and Vue are used to simplify the front-end development process and improve development efficiency and code quality. Back-end language For example, PHP, Python, Java, Ruby, etc., are used to write the back-end code of web applications. Database For example, MySQL, MongoDB, PostgreSQL, etc. are used to store data for web applications. Web server For example, Apache, Nginx, etc. are used to provide web application services. API design and development

For example, RESTful API, GraphQL, etc. are used to provide interface services for web applications. Containers and deployment tools For example, Docker, Kubernetes, etc., are used to manage and deploy web applications. Safety technology For example, SSL, HTTPS, OAuth, etc. are used to ensure the security of web applications. The above are just some commonly used Web development technologies. In fact, Web development technology is a field that is constantly developing and evolving. New technologies are constantly emerging, and old technologies are constantly being updated and optimized. development language ASP ASP is the abbreviation of Active Server Page. It is a web page that contains script code using VB Script or Jscript. When a browser browses an ASP web page, the web server will generate the corresponding HTML (an application under Standard Universal Markup Language) code according to the request and then return it to the browser, so that what the browser sees is a dynamically generated web page. ASP is an application developed by Microsoft to replace CGI script programs. It can interact with databases and other programs. It is a simple and convenient programming tool. After understanding the basic syntax of VBSCRIPT, you only need to know the purpose, properties, and methods of each component, and you can easily write your own ASP system. The format of ASP web page files is .ASP. FSO

FSO (FileSystemObject) is a file operation control of Microsoft ASP. This control can read, create, modify, and delete directories and files on the server. It is a very useful control in ASP programming. However, due to permission control issues, the FSO of many virtual host servers has become an open backdoor of the server, because customers can directly program the control in their own ASP web pages, thereby controlling the server and even deleting files on the server. . Therefore, many virtual hosting providers in the industry have simply turned off this control, leaving customers with a lot less flexibility. The W2K virtual host server I want to install has high security, allowing customers to use it arbitrarily in their own website space without any way to harm the system or hinder the normal operation of other customers' websites. CGI CGI is a standard that defines how a Web server communicates with external programs, allowing the external program to generate HTML (an application under Standard Common Markup Language), images, or other content, and the server processes it in the same way as those that are not external programs. Generated HTML, images, or other content are handled the same way. Therefore, CGI programs only enable you to generate expressive content and not dynamic content. The reason for using CGI is that it is a well-defined and widely supported standard. Without CGI, it is impossible to implement dynamic Web pages, unless some special methods provided by the server are used (nowadays, there are other technologies besides CGI gradually become the standard). PHP PHP is a server-side HTML-embedded scripting language. Its most powerful and important feature is its database integration layer. It is incredibly simple to use it to complete a web page containing database functions. In HTML files, PHP scripts (syntax similar to Perl or C language) can be referenced using special PHP tags, so that web page producers do not have to rely entirely on HTML (an application under Standard Universal Markup Language) to generate web pages. Since PHP is executed on the server side, the client cannot see the PHP code. PHP can complete any task that a CGI script can complete, but its functionality depends on its compatibility with various databases. In addition to using HTTP for communication, PHP can also use IMAP, SNMP, NNTP, and POP3 protocols. JSP

JSP technology uses the Java programming language to write XML-like (a subset of the Standard General Markup Language) tags and scriptlets to encapsulate the processing logic for generating dynamic web pages. Web pages can also access the application logic of resources that exist on the server through tags and scriptlets. JSP separates web page logic from web page design and display, supports reusable component-based design, and makes the development of web-based applications quick and easy. When the web server encounters a request to access a JSP web page, it first executes the program segment, and then returns the execution result to the client together with the HTML (an application under the Standard Universal Markup Language) code in the JSP file. The inserted Java program segments can operate databases, redirect web pages, etc. to achieve the functions required to create dynamic web pages. SQL SQL is a high-level non-procedural programming language and an important tool for communicating between database servers and clients, allowing users to work on high-level data structures. It does not require users to specify the data storage method, nor does it require users to understand the specific data storage method. Therefore, different database systems with completely different underlying structures can use the same SQL language as the interface for data input and management. It uses record collections as operation objects. All SQL statements accept collections as input and return collections as output. This collection feature allows the output of one SQL statement to be used as the input of another SQL statement, so SQL statements can be nested, which makes it It has great flexibility and powerful functions. In most cases, functions that require a large program in other languages can be achieved with just one SQL statement. This also means that
