Here I would like to talk to beginners who plan to learn technology systematically.
If you already have more experience in object-oriented development, skip these two steps:
Step 1: Master a .NET object-oriented language, C# or.
I strongly oppose learning without systematically learning an object-oriented (OO) language. It is a comprehensive approach to the object technology. If you don’t understand OO, you will definitely not be able to continue learning!
Step 2: Have a certain understanding of the .NET Framework library
You can learn the .NET Framework by developing Windows Form applications. It is a technology built on the .NET Framework. The deeper you understand the .NET Framework, the faster you learn.
For example: Here are a few concepts that are very important for mastering: object memory model, delegates, events, multithreading, assembly and application domain, security model. Of course, there are many other things in the .NET Framework, but it is difficult to truly grasp the above things without understanding and grasping them clearly.
Out of urgent and realistic considerations, many people want to learn directly without a solid object-oriented foundation, but the result is that hasteness will not be achieved. After having the OO foundation,The following are the specific learning technical steps.
Step 1: Learn HTML and CSS
This does not require learning a lot of web design tools such as Dreamweaver and Firework. The key is to understand the block structure of HTML web pages nested and the box model of CSS. Many controls must eventually be converted into HTML. Moreover, div+CSS is the current mainstream web layout model.
When learning this part, the key is to understand the concept, and not spending energy on many skills to beautify the page. It is the job of a website artist, not the job of a programmer.
Step 2: Learn JavaScript.
JavaScript is not Java, it runs mainly on the browser side. It can complete many tasks and has powerful functions: for example, it regards the HTML elements in the client web page as a tree, and can write code to access and modify tree nodes, and dynamically generate new HTML code, thereby achieving the purpose of dynamically modifying the display characteristics of the web page.
JavaScript is used a lot in current website development and is very important.
In addition, it is also the basis of the very popular AJAX technology at present.
Step 3: Learn the principles of computer networks
Find a university's <Computer Network> textbook, focus on its Internet-related parts, and learn about some knowledge about domain name resolution and HTTP protocol. This is the theoretical basis for Internet development.
Step 4: Learn presentation layer technology and be able to design web pages
It is necessary to combine the foundation of object-oriented technology that has been laid before and master the following content:
(1) How to use various web controls,
(2) Understand the way information is transmitted on web pages, such as the use of cookies, ViewState, Session, etc.
(3) The life cycle of applications and web pages, and the purpose of related objects (such as httpcontext, response, request).
(4) Implementing event-driven insider
(5) Custom user controls
To emphasize again, without the OO foundation, it is difficult to master the above techniques, so you can only be led by these things, and you will be very passive.
Step 5: Master database technology
Specifically, learn the following:
(1) Learn to use SQL Server 2005: It is not required to be proficient in its various tools and management configuration techniques, but at least know how to connect, how to build tables, and how to create stored procedures
(2) Learn and master the method of using code to manually access the database (not using the VS2005 wizard)
(3) Learn the use of data binding controls
Step 6: Understanding the multi-layer architecture
At this time, the assembly and application domains involved in the OO learning stage came in handy. Now, most website architectures use multi-layer architectures: presentation layer, business logic layer, data access layer, and the database itself.
You can first search for information about this multi-layer architecture online, and then find a ready-made, more complex open source project to analyze its architecture. Basically, they are all a routine, applied everywhere.
Some friends asked: Do you have to learn design patterns when learning architecture?
My opinion is: No! Of course, if you have learned design patterns, it is of course better. But in actual development, if you only want to apply a certain model mechanically, it will not have a good result.
My opinion:When learning design patterns, you should think more and understand more, and your thoughts will gradually be integrated into your brain. In real design practice, forget all the patterns written in the book, start from reality, and believe in your intuition. As long as the design requirements are the feasible solutions. In fact, after you do this, you will look back and find that your design often conforms to the theory of the design pattern.
Step 7: Learn XML and Web Service
First, learn the basic knowledge of XML, and read this book about XML. Then, learn Web Service. Web Service can actually be compared to remote method calls (call information expressed in XML format).
After learning this, if you are still interested, you might as well go and have a look at SOA. However, the information of SOA is all theories and concepts, which looks depressing and may be far from actual development. So, this is an option.
Step 8: Learn AJAX
The main purpose of learning AJAX is to create a web presentation layer with richer features. After the previous seven steps of learning, learning AJAX is natural, and all the foundations are already in place, so there will be no big problems.
Learning AJAX directly without the foundation is like "building a high platform on the floating sand", so the learning order of AJAX is arranged here.
Step 9: Learn RIA technology
RIA: Rich internet application can be regarded as an attempt to combine the advantages of C/S and B/S into one. In terms of specific technology, it mainly refers to Microsoft's Silverlight (WPF_E), after all, it has been Microsoft's route all the way.
I hope the introduction of this article will help you, let’s take a look together.
