Chapter 3 and 4 and Relational Algebra Chapter 3: 1. Consider the relation (20 points): PERSON_2 (Name, Sibling, Shoe_Size, Hobby) Assume that the following functional dependencies exist: Name ïÆ'  Ã¯Æ'   Sibling Name ïÆ'   Shoe_Size Name ïÆ'  Ã¯Æ'   Hobby a. Describe deletion, modification, and insertion anomalies for this relation. Consider the following relation: Name Sibling Shoe_Size Hobby Jones Fred E Model boats Jones Fred E Scuba Diving Jones Sally E Model boats Jones Sally E Scuba Diving Jones Frank E Model boats Jones Frank E Scuba Diving Greene Nikki B Embroidery Chau Jonathan C Scuba diving Chau Eileen C Scuba diving Deletion anomaly: If a Name drops a Hobby, one line must be deleted for each Sibling. For example, if†¦show more content†¦Assume that students can have multiple nicknames. a. State any multivalued dependencies. We will assume that Number ïÆ'   Name where name is not unique (i.e., there may be more than one â€Å"John Smith†, each with a different student number). Then the multivalued dependencies are: Number ïÆ'  Ã¯Æ'   Sibling Number ïÆ'  Ã¯Æ'   Nickname Note: We can not assume that Name ïÆ'  Ã¯Æ'   Nickname because Name is not unique. For example, one John Smith may have the nickname â€Å"Johnny† while another John Smith has the nickname â€Å"Joe†. If Name ïÆ'  Ã¯Æ'   Nickname then John Smith ïÆ'  Ã¯Æ'   (â€Å"Johnny†, â€Å"Joe†) which means that both nicknames apply to both John Smiths. But this is not the case – each John Smith has only one nickname, and they are not the same. b. State the functional dependencies. We will assume that Number ïÆ'   Name where name is not unique (i.e., there may be more than one â€Å"John Smith†, each with a different student number). Then the functional dependencies are: Number ïÆ'   Name Number ïÆ'   Dorm Number ïÆ'   RoomType RoomType ïÆ'   DormCost Note: This assumes that only RoomType ïÆ'   DormCost – that is, the cost of a certain type of dorm room is the same no matter what dorm the student is living in. An alternate assumption would be that (Dorm, RoomType) ïÆ'   DormCost, where the cost of the type of dorm room varies form dorm to dorm. c.

How Does Who We Are Affect How We Live - 1454 Words

How does who we are affect how we live? Based on the knowledge presented over the past few months in LD ST 322, our individual social identities, and the way they coincide with other’s qualities, I will dissect the importance of awareness of our social identities in terms of leadership. They are more than descriptors of who we are – while they may not dig too far into who we are; they dig enough that changing one of these contexts could shape the life of an individual significantly. Social identities give us a name for ourselves, and allow us to express ourselves creatively in our diverse world. To begin, what are my social identities? To start, I am male, German English, white, twenty years old, straight, and able-bodied. That covers the six inner ring identities found in the inner circle of the â€Å"Diversity Wheel†, which are: gender, ethnicity, race, age, sexual orientation, and physical ability. On the outer ring of the wheel, the identities are: marital st atus, income, work background, education, parental status, geographic location, religious beliefs, and military experience (Johnson, 2006). I am a single/unmarried college student, and have almost a year-and-a-half of school under my belt. My family and I are members of the upper-middle class, and I’m the youngest in my family. I was born and raised in the Midwest (northeast Iowa to be more specific), grew up in a Christian home and have carried my Christian faith with me into college.

Versace Visions and Stiletto Dreams free essay sample

Armed with an old veteran at my side I pushed open the glass doors, preparing for the jungle thriving ahead. Deep breath. Map out your surroundings. Remember the plan. Ready or not, we plunged into a swarm of chiffon and silk, questionable polyester and cotton blends and the season’s latest animal prints. Focus. Focus. Take a quick left to avoid saleswoman spraying musty-smelling perfume in your direction. Dodge the hoard of vultures, or possibly old women, tearing the sale rack to shreds. One more right past the accessories . . . Most people esteem clothing as little more than a status symbol, a way to fit in or simply articles to put on because nudity is not well accepted in today’s society. To these fashionably-challenged folks, I can scarcely relate. Valentino’s extensive vintage collections mirror Michelangelo’s Sistine Chapel and the sight of an intricately-sewn couture gown leaves me completely awestruck. We will write a custom essay sample on Versace Visions and Stiletto Dreams or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Although the scarlet mark of ketchup stain on white pants strikes a chord of terror in my heart, I value fashion for much more than the obvious aesthetic appeal. Every outfit is an art form and an opportunity to create a mood, evoke emotion and transform one into a new character. If a picture is worth a thousand words, a design proclaims a million. Nothing is more satisfying the challenge of hunting down the perfect combination from the main piece to every last accessory. Every spring and fall holds the promise of new lines and new beginnings. Growing up, I declared many careers to be my destiny, from teaching to tap-dancing. It was not until I reached the age of eleven that I realized that the fashion industry was the party and I yearned to be V.I.P. While teachers assigned math problems on the white-board, I designed outfits in my head. Assorted shoes styles, from strappy stilettos to sporty sneakers, bordered my worksheets. These intricate garments dancing in my imagination oft en lost their marvel when transferred to paper. My hands lacked the deft ability to translate the language of these images into a reality. Coming upon this heartbreaking conclusion at the rife, old age of thirteen, I felt my career in fashion had ended before it had even begun. My focus shifted heavily onto academics after entering high school. Achieving high grades in honors classes, I received no shortage of career advice, â€Å"Just think about it! You could become a pharmacist! You’ll get a job right out of college making a nice salary with great hours. Doesn’t that sound perfect?† The mundane vision of myself spending a lifetime bathed in a shapeless, white lab coat immediately resolved that question. Seeing other students follow straight and narrow paths has only affirmed my desire to diverge. Dreaming of runway shows, creative freedom and fast-paced photo shoots sparks a twinkle in my eyes and a whirlwind of thoughts through my mind. Today I find myself holding the keys to many doors, but more than ever, I am reeling with the desire to learn, create, style and delve into anything fashion-related. Contrary to my prior beliefs, the fashion industry is bursting with opportunities in addition to just designing. Fortunately for me, these careers are possible without ever having to stitch a single seem or bead a single blouse. . . . Suddenly, gleaming before my very eyes were those perfectly-cranberry mary-janes made of shiny, patent leather. Slipping them on, images of crisp shirts and pencil skirts pieced together in my mind. The dangerously high heels caused me to wobble for a moment, before strutting down my fantasy catwalk.

Zuma beach Essay Example

Zuma beach Essay Zuma Beach holds the status of a state beach and shows its coordinate at 34 ° 0 ´ 58.18 N, 118 ° 49 ´ 19.51 W of California at 30000 Pacific Coastal Highway in Malibu, California (â€Å"Zuma Beach County Park.†). The geographical features boast about it for being one of the longest and popular beaches in Los Angeles County. The beach is reckoned for long and wide sands. Among many features and facilities Zuma holds an excellent condition for the surf lovers. To add more feathers in hat the beach has been ranked among the healthiest beach referring its clean water condition (Garbee, Gottesman, Helper, Bates Schwartz 38). It is also the famous in California for its finest white sand strands. To coordinate the geographical layout of the place, it gives sense to the famous surfing beach. As it lies open on the coast beyond Santa Monica Bay; the heavy breakers take the transit crushing in from the north to Zuma, creating perfect wave formations for the surfer on board. The majestic sun catches the body surfer too, to let them try to catch the big one itself (â€Å"Zuma Beach Surf Report and Forecast.†). Zuma is also unique for it changes the colour of the ocean and the cliffs into various shades of green; depending on season and sun light. Approximately during mid December to March the beach hosts whale watching for the hikers at Point Dume, 1 mile from the beach, giving a good chance to spot California Gray Whales. Unfortunately, among all these beauties; in recent past the beach has been through many disputes with the nude beach hoppers, residents and the county sheriff (McKinney 67-68). Apart from moral policing, other infrastructural problem creeping in is the traffic heading to beach at Point Dume are taking Zuma Beach County Park, where space is small and with the volley ball nets, lifeguard watch tower, sun bathers, surfers and the beach fares it falls short in its layout and elegance (Riedel, Crowell 115, 137).

Since the region around the Point Dume is a seasonal passage for the Whales, any extraction or refinery activity of petroleum will harm both, leading to ecological and human catastrophe (Emery 241). As we have traced some of many that could be, the solutions can mostly addressed to the high voltage pre existing security system of Lifeguards from Los Angeles County Fire Department with their robust structure of 14 watch towers and one of 4 L.A. County Section Headquarters stationed at the center of the beach (â€Å"County of Los Angeles Lifeguard Division.†). The first problem was the advocates of the nude beach. The agitation of the residents and sheriffs towards this problem is sensitive enough to stop it for once and all with the iron hand of the Court Order, which the U.S. citizens are, ought to obey (â€Å"Los Angeles County.†). As per LA County Fire Department actions the congestion of the car parking problem can be taken care of, if the traffic take a round about at Point Dume to the secluded section of the beach. For the safety and evacuation system for any odd event the beach goers have reasons to rely on the robust and proven operational layout of the LA C ounty Fire Department (Los Angeles County Fire Department). On the petroleum issue the safest possible way to execute the task is to set up a hinterland pumping station, connecting the source area through underground pipelines; even underneath the seabed till the location. In short, to preserve the wonders of Zuma, it needs to reorganise and extend the operations of the existing organisation and a creative approach of the industrial and urban development plans.
