How are databases used in organisations - Essay Example Another type of databases is distributed databases. These are databases which are scattered and stored over different systems on a network. Object-oriented databases use the concept of classes and subclasses to store and organize data. Databases usually do not exist in isolation but are part of database systems. A database system, besides the collection of records, provides a number of features such as searching for records, accessing them and updating them. Typically databases use the language SQL (Structured Query Language) to access the data and make changes to it. Popular database systems include Oracle, IBM’s DB2 and Microsoft Access. Databases play a vital and indispensible role in organizations today and are of great importance. One of the reasons for this is that they have replaced the old paper files and records. This makes the information become compact and is no longer scattered in paper files. Not only do paper files taka a lot of space, they are also vulnerable of being destroyed by fire etc. Besides saving in the space, the database provides an easier access to data. It allows the users to retrieve data in very little time and to update it easily. Data from a database can be retrieved and sorted in a number of ways depending on the requirements.

Indeed, a portion of the critics suggests that your writings provoke multivalent and ambiguous, rather than offering neat shorthand for transition from the traditional to modern culture. Your take please? Benjamin: Well, I think their basis for criticism is rather vague. In my essay The Work and Art in the Age of Its Technological Reproducibility, I specifically emphasize on the concept of aura and the decline of photography, similar to other technological innovations. Further, I challenge the uniqueness and originality of photography due to the unprecedented replications. Benjamin: A programmatic analysis of the essay that I previously mentioned will show that I present the relationship between photography and aura as a clear-cut opposition. Thus, photography, as a medium of mechanical reproduction, is among the driving forces behind the decline, and thus destruction, of aura. I clearly assert that the element that withers in the era of technological reproducibility of artwork is its aura. In essence, the process is symptomatic, and perhaps extends beyond the boundaries of art.

In this regard therefore, the contemplation characteristic of the traditional spaces of museum and gallery submits to an eagerness for control and possession. Me: That is a very sensational explanation.
