Database In The Real World Essay

996 words - 4 pages

In today’s digital era, our life seems easier because of its technologies. Computer technology is the most influential among others. It supports anything that related to the new inventions and innovations. One of important role in computer technology is a database. Although database is not as popular as web application in computer technology innovations, it determines whether such application system is good or not. Database is ‘a shared collection of logically related data and its description, designed to meet the information needs of an organization’ (Connolly & Begg 2010, p. 65). Some organizations have their databases to be accessed via networking system. We are able to interact with them everywhere. For example, we access them such as database in flight data, student system, bank, library and Facebook. Although those online database systems make our life easier, there are some risks to be considered.

Database is a place where data is stored and accessed. For example, database in flight system facilitates both passengers and the airlines’ crews. The passengers are able to order flight tickets in their online systems, as they input their data there. After the tickets are booked, they already have passengers’ data in their database such as passenger’s name, flight number, place and time of departure, place and time of arrival. It makes the airlines’ crews easier to organize the flight system. Moreover, they will have the history of the flight saved in their database.

In Flinders, students’ lives are controlled by the database in the student system. The university can monitor whether the student has enrolled for the forthcoming semester and paid their tuition fee. When enrolling topics, the student input their student ID. Then, the database selects the only topics that are available for that student only. For example, the student is taking Master of Information Technology, so the list of topics must be the topics for Master of Information Technology not the topics of Master of Public Administration. The information about how much tuition fee student should pay is also in that system.

When a student pays their tuition fee using his credit card, the bank’s database updates his account balance simultaneously. As a result, Flinders University doesn’t have to tell the bank that one of its students is paying tuition fee with his money in the bank. Now bank’s database is accessible everywhere. We can connect with them on the internet, ATM, and mobile phone. Because of that, banking system should have strong security. They provide us with PIN and nobody knows the number even the bank itself. It is encrypted in their database system.

Another database function in Flinders University is its Library. Besides organizing books in bookshelves based on categories, the library is also organizing books in the database. So, students can search the book searched based on title, author, publisher and ISBN. The advantageous of using database in the...
