This week was a normal Friday on the thirty of Mach. Three weeks before this we did not study in class so for that day I came to the again as usual. So this week I learnt about web application. In fact I use and expose it every day but I did not know what exactly web application is. So let I explore more details about web application.
A web application is any application that uses a web browser as a client. The application can be as simple as a message board or a guest sign-in book on a website, or as complex as a word processor or a spreadsheet.
What are the Benefits of a Web Application?
A web application relieves the developer of the responsibility of building a client for a specific type of computer or a specific operating system. Since the client runs in a web browser, the user could be using an IBM-compatible or a Mac. They can be running Windows XP or Windows Vista. They can even be using Internet Explorer or Firefox, though some applications require a specific web browser.
Web applications commonly use a combination of server-side script (ASP, PHP, etc) and client-side script (HTML, Javascript, etc.) to develop the application. The client-side script deals with the presentation of the information while the server-side script deals with all the hard stuff like storing and retrieving the information.
The next step our lecturer gave more details and we focused more on web application 2.0. A Web 2.0 site allows users to interact and collaborate with each other in a social media. This one we can easily approach it in our daily life and I believe that nowadays people are using them. For examples, Facebook, Twister, blogger and wikis, and so no. That’s all for this week……………………thank you……………………..
Finally I have reached at the end of this semester so this lesson is the last lesson. It’s about database and basically I learnt the basic usage of MS Access. Before access our lecture gave us some explanation about the database. A database is a collection of information that is organized so that it can easily be accessed, managed, and updated. In one view, databases can be classified according to types of content: bibliographic, full-text, numeric, and images. A database management system (DBMS) is a software package with computer programs that control the creation, maintenance, and use of a database. It allows organizations to conveniently develop databases for various applications by database administrators (DBAs) and other specialists. Types of Database Models: The hierarchical database is based on the hierarchical data model but with records. The model resembles an upside down tree. The hierarchical database is viewed as a Parent/ Child relationship using ‘one-to-many’ relationships, The Network database was developed to improve short comings of the hierarchical database. The network database differed in a couple of ways. The network database uses one-to-many relationships, The relational database emerged around the 1970’s and is still a leading technology for database management, The object orientated database, models the elements as objects, which is similar to object programming. By designing object databases with the same language. So that is some information about database. In the class I also access the Microsoft access database that never use before. So for this semester I have learnt many things that are new approach for me. Lastly I would like to say thank you too much to my lecture for giving me the knowledge………………………..
