Basic Database Design Concepts - 2587 Words

The Fundamentals of Database Design To end up with a good ‘relational database’ application, you need to ask: Do I actually need one? If so, how far do you want to take it? By this I mean, is this to be a simple database to store information about only one, or very few, related entities (i.e. a list of people who attended a certain event, and how they came to hear about the event) which are not likely to change; or a permanent and well used application with several different entities (i.e. Staff, Departments, Branches, SalesFigures for various periods/staff members/departments) which are constantly changing. If the forma is the case, a simple ‘Flat File’ database is all that is required. There are several basic database products on†¦show more content†¦This is extremely useful if the application is to be distributed among users and the database itself can be centrally stored and maintained by database specialists. The Development/Test db will be already in the correct format for the transfer to a backend server and the Access application will be ready to connect to it. Examine your current database There is no need to reinvent the wheel. If you have a current system, have a good look at your tables. If you need to make ‘sub-columns’, or the same data needs to be entered on many lines, the database is indeed set-up wrong. This is very often identified by spotting ‘repeating attributes’, within the same entity, or lists of values for one attribute. For example, you may have a table called StaffMembers with an attribute (a column heading) called ‘CompletedCourses’ where you need to list several courses for each staff member. To improve on this, the database needs to be ‘Normalised’, and probably redesigned. Design the database correctly from the outset The first thing you need to do is make a list of items you need to store information about. These are called Entities or Relations (or Classes in OOAD) Next you need to list all the things about each Relation that you need to record. These are the Relation’s Attributes (or the Class’ Properties in OOAD).

The Degradation of Music for Mass Consumption Essay

The Degradation of Music for Mass Consumption From the very first time that someone decided to experiment with a musical tradition, the cry has gone out that true, pure, and good music is dead to society, and that music itself is on a perpetual slide to oblivion. All apostrophe aside, this is a serious matter to consider. Music inhabits a significant place in all cultures. Musical style is very much a function of the Zeitgeist, reflecting the prevalent tone of the dynamics and pulse of a specific time. As an artistic medium, music has as much to do with the shaping of society, or as a shaped response to society, as do television, literature, language, or art. The fact that we find music pervading so many of our endeavors bears†¦show more content†¦So it may well be that a listener is completely unable to identify with, much less assimilate, a piece. And this is the problem. Music is a personal, individual language, not collective, like the spoken language of words. Therefore, people have difficulty in determining and establishing value in music. What is good music to one, may not be to another, and for very good reasons. What constitutes positive and negative change in music? If music doesnt communicate in absolute terms, how is anyone to decide anything concrete about it? Doesnt that just make all music relative? Isnt one piece just as good as any other? This quandary of indeterminacy can be seen in todays music and in peoples responses to music in general. One always seems to hear the bemoaning of the present days musical style. Today, its that machines (i.e., computers, synthesizers, digital recorders, etc. . . . ) are the primary instrument of musical production. Popular music is characterized as boring, monotonous, stale, unoriginal, and simple. Complaints of this vein are nothing new. Viennese classicists like Mozart and Haydn were accused of destroying the nobler aspects of the Baroque, of Bach and Monteverdi. They, however, were criticized for dispensing with the single line melodies of earlier music, mostly folk songs and church hymns. Beethoven desecrated Viennese classicism; Verdi, traditional recitative opera; and Wagner, well . . . , everything.

The Cask Of Amontillado Lit Analysis Essay free essay sample

The Cask Of Amontillado: Lit. Analysis Essay, Research Paper Clint Kale 11/22/97 Literary Analysis Literary Analysis: The Cask of Amontillado In Edgar Allan Poe # 8217 ; s short narrative, # 8220 ; The Cask of Amontillado, # 8221 ; a character named Montresor vows retaliation on the adult male who insulted him excessively many times. You might admiration why he wants to be avenged so severely. This literary analysis will demo grounds of why Montresor killed Fortunato. Toward the beginning of the narrative Montresor appears to be a brainsick adult male. He lets the reader know that when he says # 8220 ; I continued, as was my habit, to smile in his face, and he did non comprehend that my smiling now was at the idea of his immolation # 8221 ; 1 ( pg. 703 ) . This leads you to believe that the full program of slaying Fortunato was pre- meditated. Montresor knows that acquiring ultimate retaliation on Fortunato has to be done with impunity. If there was any opportunity Fortunato could acquire back at him, he would non be successful. The thought of killing Fortunato is one of the lone ways a individual could demand retaliation with impunity. Montresor decides to utilize the vino vault as Fortunato # 8217 ; s concluding resting topographic point. Clint Kale Pg. 2 This is dry because Fortunato is good known as an expert in vino. When Fortunato starts coughing Montresor urges him to travel back ; this lone makes Field-grade officer rtunato want the cask more. Montresor answers, # 8220 ; You are rich, respected, admired, beloved ; you are happy, as one time I was # 8230 ; # 8220 ; You are a adult male to be missed. # 8221 ; # 8220 ; For me it is no affair # 8221 ; ( pg. 704 ) . Montresor is acrimonious, discredited and likely covetous of Fortunato from the grounds of these quotation marks. The coat of weaponries in the Montresor household is one of the biggest hints as to why he killed Fortunato. Montresor describes to Fortunato the image of his weaponries: # 8220 ; A immense human pes vitamin D # 8217 ; or, in a field cerulean ; the pes crushes a serpent rampant whose Fangs are imbedded in the heel # 8221 ; ( pg. 705 ) . This is symbolic of the full narrative. Montresor is the snake and Fortunato is the pes. Fortunato may hold trounced upon his feelings but Montresor will hold the last laugh when Fortunato becomes poisoned. Toward the terminal of the narrative, the reader knows why Montresor killed Fortunato. He now does non look like the same brainsick individual he was at the beginning of the narrative. Although he does kill Fortunato, Montresor keeps a really methodical attack to making so. Montresor # 8217 ; s coat of weaponries slogan is # 8220 ; Nemo me impune lacessit # 8221 ; ( pg. 705 ) . Which means # 8220 ; No 1 insults me with impunity. # 8221 ; This means Montresor is following his household motto absolutely. Which makes it clear why Montresor killed Fortunato. He was protecting the award in his household.

Singing essays

Singing essays If I could write about one thing and one thing only, I would write about singing. I know many people who sing whether they actually have talent or not, but singing is my true passion; it is not just something I do in my spare time or just another accomplishment to check off of the list of things I can do, but rather it is something that has true meaning to me. I dare say that it is the most important thing to me in my life besides God and my family. It is something I know that I will always have. While the athletes and beauty queens will eventually lose their skills and flattery, I will always be able to sing or at least listen to the music that I hold so close to my heart. I never thought I would end up as a vocalist. When I was younger I always chose choir over band, but I never really enjoyed it. It was just something I had to do because I couldnt play an instrument. I always thought of music people as strange: the dorks who were too uncoordinated to do anything else. But now I know that musicians are some of the most brilliant, coordinated people in the world. When I entered Junior High at Briarwood Christian School I joined the choir because none of the other electives really interested me. I sang small solos in some of the songs, as did everyone else, and I would participate in some of the choir festivals and concerts that were held, but I never took it seriously. I didnt even think I could really sing. However, toward the end of my eighth grade year everything changed. The choir director at my school wanted me to participate in a solo festival that was being held for beginning singers. I agreed to do it, not knowing what I was getting myself into. My selection was Here I am, Lord, arranged by Jack Shraeder. With the competition only two weeks away, my mother suggested that I get some help, so we went to my church, South Highland Presbyterian, on Wednesday night and called on Dr. John J. who was ...
