Client and server in a database client/server environment

 

4. Operation of database client/server systems requires a networked environment where the processing of an application is split between the client and the
server. In view of the above context, as a Database Administrator, answer the following:

a) Using valid examples relating to real-time scenarios, in your own words, discuss the ideal situations to use two-tier and three-tier client/server database
environments. Note: Simply writing theoretical points should be avoided, your solution must be related with the chosen scenario. You need to draw diagrams of
your own, which carry marks. (5+8+5=18 marks)

b) Discuss the role of client and server in a database client/server environment. Your solution must include relevant examples.

While Denman Waldo Ross characterized general principles about the connection between a plan and agreement, parity and musicality, Don Norman adopted the strategy from a progressively logical side. He clarified the impact configuration has on feelings through psychological science. Stefan Sagmeister and Jessica Walsh imparted their insights and research learns about the field of plan and excellence in which they expressed the significance of magnificence as far as usefulness. The enormous counter-development to enthusiastic plan was the Bauhaus, which is quickly clarified and reflected in this proposal also. The center thought behind the Bauhaus was the association from creators to the craftsmanship and to make structure just dependent on usefulness. The subsequent fragment is a more profound comprehension of why configuration would impact or summon explicit feelings. Numerous investigations about the impact of typography, shapes and hues are being broke down and condensed. Ultimately, a reflection, end and conceivable inference of this postulation will be made to locate a potential response to the speculation whether it is conceivable to summon explicit feelings through explicit structure and on the off chance that it is conceivable to make a general example for future plans.

2.1 DEFINITIONS OF EMOTION

“Feeling is an arrangement of development that remained in the heart

without the authorization of the will, and that out of nowhere changes

the shade of the contemplations.” – Alain

To discover one meaning of feeling has been a battle that Kleinginna and Kleinginna attempted to illuminate through gathering a hundred of various meanings of feeling and attempting to make a consensual and logical definition which finished up to: “Feeling is an intricate arrangement of cooperations among abstract and target factors, interceded by neural-hormonal frameworks, which can (an) offer ascent to full of feeling encounters, for example, sentiments of excitement, joy/dismay; (b) create psychological procedures, for example, sincerely important perceptual impacts, evaluations, marking forms; (c) enact far reaching physiological changes in accordance with the stirring conditions; and (d) lead to conduct that is frequently, however not constantly, expressive, objective coordinated, and versatile” (Kleinginna, Kleinginna 1981, p.355). The psychological researcher Donald A. Norman shows his meaning of feeling all the more strikingly in his book Emotional Design. He discusses the significance and worth that feelings bring to our regular day to day existence. He further clarifies that despite the fact that the capacity and ease of use of an item is significant, the feeling and delight of utilizing it ought not be stifled (Norman, 2004, p.8). Both of these definitions lean towards the logical side and attempt to picture the procedure of feelings just as feelings being impacted subliminally. They additionally share a similar comprehension of the significance of feelings. The two definitions clarify that through feelings and feeling, the individual can name or choose whether a procedure, item or circumstance is certain or negative, sheltered or hazardous.

2.2 EMOTIONS IN DESIGN

2.2.1 Pure Design

Denman Waldo Ross was a structure scholar who needed to show that there were standards and decides that craftsmen followed to make workmanship. In his eyes, workmanship was an outflow of feelings or emotions, however it was additionally not a matter of taste whether somebody would welcome certain craftsmanship or not, nor was it made without clarifications or an explanation (Ross, 1907, Preface). The fundamental standards or modes that workmanship follows are congruity, which is the most complete and significant, trailed by equalization and mood that lay right inside agreement. His comprehension of excellence is all the more being an encounter activated by these standards, which make a result of delight and satisfaction (Ross, 1907, p.2f). Making workmanship or configuration dependent on these standards is the thing that Ross called Pure Design. He characterized it as an “offer to the eye similarly as total music bids to the ear. The reason in Pure Design is to accomplish Order in lines and spots of paint, if conceivable, the flawlessness of Order, an incomparable occurrence of it, the Beautiful: this with no other, no further, no higher thought process; only for the fulfillment, the joy, its enjoyment. In the act of Pure Design we focus on Order and trust in Beauty” (Ross, 1907, p.5). In his hypothesis he characterized rules for his comprehension of agreement, parity and mood in structure.

To accomplish Harmony inside structures, there are different focuses to consider. The first being the request for agreement. To produce a symphonious state, bearings, edges and dissimilarity ought to be equivalent when making rehashing interims (Ross, 1907, p. 12). Another part of congruity is the utilization of tones. Focusing on comparative shading esteems, for example, tint, immersion or brilliance will shape a congruity inside comparable shading ranges (Ross, 1907, p.158).

The joining of request to adjust can be produced through “equivalent separations in inverse bearings” (Ross, 1907, p. 17).
