Information Tech. and the Canadian Economy Essay

Information Tech. and the Canadian Economy - Essay Example The people who were providing labor force in Canada are retiring while there are no new people to fill up their positions. The number of hours per capita from the senior citizens does not help the economy. The young men and women should, therefore, get an education. They should also have the desire for change to be able to achieve the required amount of labor force to move Canada’s economy (Miner, 2013). Immigration is one of the ways to improve the labor force. There has been a debate on the type of training and preparation the next generation should go through to ensure there are enough people for the jobs in future. In order to prepare the next generation for the labor force, the level of education attainment in the country should be increased (Clever, 2012). The level of education for the young men and women should go beyond high school. It should be through to getting diplomas, degrees, apprenticeship, industry qualification, certificate, etc. The different institutions b eyond high school help the young people acquire skills and education for different parts of the labor force. There has been major progress since 2010 as the number of high schools graduations have gone up every year. The high school graduations increase means the rise in enrollment to post-secondary education. The progress has reduced the estimates for the needed labor force in the country. It is both good and bad news for the young men and women in Canada. The reduction of the need for labor force is right in that the shortage of workers in Canada reduces significantly. It is bad in that it slows down the economic recovery and growth with Ontario, New Brunswick, Quebec, Nova Scotia, and PEI being the ones to take most of the pain. The cities named above economies suffered the most when the economy of Canada went down (Miner, 2013). The labor force in the above locations relatively went down because of its population consisting mainly of senior citizens who

Database Theory and Design Coursework Example | Topics and Well Written Essays - 500 words

Database Theory and Design - Coursework Example Normalization is a formal process for deciding which attributes should be grouped together in a relation (Elmasri & Navathe, 1994). It involves decomposing relations with anomalies to produce smaller, well-structured relations. Three problems usually arise in databases where relations are not normalized. First we could have insertion anomaly, this is where adding new rows forces the user to create duplicate data in the database. Secondly we have modification anomaly, i.e. where changing data in a row forces us to make changes to other rows because of duplication. Finally we have deletion anomaly which means that when we delete rows we may cause a loss of data that would be needed for other future rows (Connoly & Begg, 2005). First Normal Form (1NF) means that all multi-valued attributes are removed, so that we have a single value at the intersection of each row and column of the relation table. Second Normal Form (2NF) means we apply the rule for 1NF then we remove all partial functional dependencies. Third Normal Form means we apply the rules for 2NF then we remove all transitive dependencies. ASSIGNMENT – client-id#, consultant-id#, start-date, work-hours, job-code, rate-per-hour is in 2NF (second normal form). This is because rate-per hour is transitively dependent on job-code. Therefore to make ASSIGNMENT into third normal form (3NF) we remove rate-per-hour from its attributes to end up with ASSIGNMENT – client-id#, consultant-id#, start-date, work-hours,
