Based on statistics, it can be seen that this model is increasingly developing vigorously in the Vietnamese market in general and Ho Chi Minh City in particular. This means that the competition between coupon websites is increasing while the attraction and interest of consumers in this type is decreasing.
Positive side
Businesses have more opportunities to advertise and sell products and services.

Consumers have more choices and incentives in addition to buying cheap products. When a playground has many competitors, in order to survive and continue to develop, groupon clone websites will need to continuously adjust and improve from code, interface, website features, especially customer service. Therefore, users will also be better served.
Negative side
Many websites or suppliers introduce and sell products and services that are not as advertised, are not really cheap, or discriminate between customers who use coupons and those who do not. This leads to customers complaining, doubting that "cheap is bad" and losing trust in the form of buying coupons.
Some websites operate in a stereotyped manner like Groupon, from the form to the advertising products, even copying PR articles from other coupon websites, lacking creativity and flexible changes to suit the trends, culture and shopping habits of Vietnamese consumers.
Customers who buy coupons tend to spend cautiously, so they sometimes make requests that are not included in the deal conditions or rarely reuse the product/service after the deal due to the mentality of waiting for the supplier to sell the coupon before buying.

1.3. TOOLS USED TO BUILD THE CHEAP SUPERMARKET WEBSITE MUA MUA.
1.3.1. Visual studio.Net 2010
- Microsoft Visual Studio.Net 2005 is an integrated development environment (IDE) developed by Microsoft. This is a type of computer software used in software development. Integrated development environments include:
- A source code editor: used to write code.
- Compiler and/or interpreter.
- Automatic build tool: when used, it will compile (or interpret) the source code, perform linking, and can run the program automatically.
- Debugger: supports error detection.
- Additionally, it may include a version control system and tools to simplify the work of building graphical user interfaces (GUIs).
- Many modern unified development environments also integrate class browsers, object inspectors, class hierarchy diagrams, etc. for use in object-oriented software development.
- Thus, Microsoft Visual Studio 2005 is used to develop consoles and GUIs along with applications such as Windows Forms, web sites, as well as web applications, and web services. They are developed based on a native language code as well as managed code for the supported platforms Microsoft Windows, Windows Mobile, .NET Framework, .NET Compact Framework and Microsoft Silverlight.
- Visual Studio supports many programming languages, such as: C/C++ (Visual C++), VB.NET (Visual Basic .NET), and C# (Visual C#)... as well as supporting other languages such as F#, Python, and Ruby; in addition, it also supports XML/XSLT, HTML/XHTML, JavaScript and CSS...
- Inheriting the features of Microsoft Visual Studio.Net 2005, Visual studio.Net 2010 has many more superior features.
Advantages:
- Its biggest advantage is its very fast development speed. With the same project, if you develop it in Java, it will take one and a half to twice as much time as if you develop it in Visual Studio.
- The second significant advantage is its flexibility and huge function and object library. Programmers who are familiar with the C language can easily access it through visual C++, those who are Java enthusiasts can also access it and visual C#. And those who are working in Visual Basic can still continue on the path they are on but with an increasingly wider reach.
- Its next advantage is the user-friendly programming tool along with the MSDN online library system that can meet the maximum learning needs of programmers. When you are almost stuck, press F1, you will definitely find what you want.
Disadvantages:
- The biggest drawback of products made from Visual Studio is that they depend on the Framework library. And can almost only run on Windows operating system.
- Second disadvantage: Visual Studio is not Open source, so it is very difficult to find a complete source code somewhere online.
1.3.2. SQL Server 2008 database management system
Microsoft SQL Server is a relational database management system (RDBMS) that operates on a client-server model that allows multiple users to simultaneously access data, manage valid access and user rights on the network.
SQL Server 2008 is a database management system that is widely used in the world in general and in Vietnam in particular. SQL Server 2008 improves performance, reliability, programming ability and ease of use compared to previous versions. SQL Server 2008 focuses on the ability to process online transactions on mobile devices, applications in e-commerce and data warehousing.
The query language of Microsoft SQL Server is Transact–SQL(T–SQL). T-SQL is an extended SQL language based on the standards of ISO (International Organization for Standardization) and ANSI(American National Standards Institute) used in SQL Server.
The T-SQL language in SQL Server 2008 extends the ANSI SQL-99 standard while SQL 2000 extends the ANSI -92 standard.
SQL Server 2008 provides many new popular utilities, data types, functions, clauses and objects,... helping software developers store, calculate, compile statistics, search and report for all management applications.
Advantage
- High security.
- Suitable for large projects.
- Easy to use graphical interface.
Disadvantages
- If you want to use it, you have to buy the copyright from the supplier at a not small price.
1.3.3. Some tools to support interface design
Adobe.Dreamweaver.CS5
- Dreamweaver is a professional Visual Editor program for creating and managing websites. Dreamweaver provides advanced website drafting tools, supports DHTML (Dynamic HTML) features without writing command lines, helping those who do not know web programming to design dynamic websites easily and intuitively. With Dreamweaver, you can easily embed products from other web design programs such as Flash, Fireworks, Shockwave, Generator, Authorwave, etc.
Adobe Photoshop CS5
- Adobe Photoshop (commonly known as Photoshop) is a specialized graphics software of Adobe Systems, launched in 1988 on Macintosh computers. Photoshop is considered the market leader in bitmap image editing and is considered the standard for industries related to photo editing. Since version Photoshop 7.0 launched in 2002, Photoshop has revolutionized bitmap images. The latest version is Adobe Photoshop CS5 (Version 11.0): with 2 versions Standard and Extended in Creative Suite 5, released on June 15, 2011.
- In addition to its main ability to edit photos for publications, Photoshop is also used in activities such as web design, drawing all kinds of pictures (matte painting and many other genres), drawing textures for 3D programs... almost all activities related to bitmap images.
- Adobe Photoshop is compatible with most other Adobe graphics programs such as Adobe Illustrator, Adobe Premiere, After Effects and Adobe Encore.
Macromedia Flash 8
- Adobe Flash (formerly Macromedia Flash and before that FutureSplash), or simply Flash, is used to refer to both the multimedia creation program and the software used to display them Macromedia Flash
Player. This computer program is written and distributed by Adobe Systems (the company that bought Macromedia).
- Flash uses vector and raster graphics. Flash also has its own scripting language called ActionScript and is capable of transmitting and loading audio or video streams. Macromedia Flash should be used to refer to the program that creates Flash files. Flash Player should be used to refer to the application that executes or displays Flash files. However, Flash is used to refer to both programs.

In addition, I also use Adeo 3D flash slideshow software to design banners. This software is quite convenient and easy to use with beautiful layer effects.
1.3.4 ASP.NET
- ASP.NET is the latest web application framework developed and provided by Microsoft with the extension .aspx, allowing programmers to create dynamic web pages, web applications and web services. It was first introduced to the market in February 2002 with the release of
1.0 of the .NET framework, which is the successor technology to Microsoft Active Server Pages(ASP). ASP.NET is compiled under the Common Language Runtime (CLR), allowing programmers to write ASP.NET code in any language supported by the .NET language.
- ASP.NET pages are pre-compiled instead of having to read and translate each time the website receives a request, unlike pages using other languages, each time the website is called, it has to be re-compiled, which consumes a lot of resources for processing like that, this problem slows down the system's processing progress.
Advantages of ASP.NET
- ASP.Net allows you to choose one of the programming languages you love: Visual Basic.Net, J#, C#,…
- ASP.Net pages are precompiled. Instead of having to read and interpret each time a web page is requested, ASP.Net compiles dynamic web pages into DLL files that the server can execute quickly and efficiently.
- ASP.Net strongly supports the rich and diverse library of .Net Framework, working with XML, Web Service, accessing database via ADO.Net, ...
- ASPX and ASP can work together in one application.
- ASP.Net uses a new programming style: Code behide. Separate code, separate interface. Easy to read, easy to manage and maintain.
- Programming architecture similar to Windows applications.
- Support for managing the status of controls
- Automatically generate HTML code for Server controls corresponding to each type of Browser
- Supports multiple cache mechanisms.
- No need to lock, no need to register DLL
- Allows multiple forms of application configuration
- Global.aspx has more events
- Manage sessions on multiple servers, no need for Cookies
1.3.5 ADO.NET
Functions of ADO.NET
ActiveX Data Objects are Microsoft's database access technology. They provide you with a single interface for accessing all types of data, no matter where it is on your disk. They also provide the greatest flexibility of any Microsoft data access technology.
Advantages of ADO.NET
- Users can work with databases through Dataset without having to worry about the specific type of database.
- Save effort in building applications, no need to rewrite programs when changing databases.
- This is a disconnected database model or offline database. Because Dataset is independent of the database.
