How useful are databases for businesses today?

How useful are Databases for Businesses to day? I am going to plan an investigation into how useful databases are for a company in the 21st century. Firstly I am going to explain what a database is. A database is a collection of data that can be used as information. It is understandable as information because of the headings and structure used in the database file. -A FILE is the information given in a subject e.g. Patients records. -A RECORD is a set of information about one given thing e.g. one patients record would contain just information about that person. -A FILE is one piece of information in a record; it also gives meaning to a list of, otherwise meaningless, information e.g. the field heading 'First name' gives meaning to a list of words such as 'Emma', 'Joe', 'Frank' and 'Tom'. -A QUERY is a search of the database for a certain piece of information that could be useful to you, e.g. if you want to sell a platinum credit card then you could do a search for people living in a certain area and then send the information to those people using a mail merge. Alternatively, if you worked in a doctors surgery you could do a search of people who needed a booster jab. -A MAIL MERGE is a letter containing the results of the query sent to certain people who would possibly be interested in that certain information. The type of information that a business might want to

Why was the Weimar Republic so unpopular with many Germans between 1919 and 1923?

Why was the Weimar Republic so unpopular with many Germans between 1919 and 1923? After The War a new type of government was set up in Germany. This was the Weimar Republic. Between 1919 and 1923 it had to deal with many problems. 1919 saw the Spartacist Rebellion and the new government was forced to agree to the unpopular Treaty of Versailles. In 1920 the Kapp Putsch succeeded in taking over the government for a while. In 1921 Germany began to pay reparations and inflation began to get out of control. Two years later France and Belgium invaded the Ruhr and the hyperinflation was now out of control. The NSDAP, led by Adolf Hitler and General Ludendorff, tried to take over the government at this time. This bad start had three main causes. The First reason why the Weimar Republic started badly was that there were political problems. Some people were very upset that the Kaiser had been forced to leave. This was a politically a bad start because it showed that some people would have preferred to have had the previous political system. The communists disliked the new republic because not much would change. The workers would still be poor and the rich would still be rich. They wanted the workers to have power. This contributed to the Weimar Republic's early unpopularity because there are a group of people (the communists) who know that they will not agree with the key policies

Was Hitler a Totalitarian Dictator?

Was Hitler a Totalitarian Dictator? A Totalitarian is a dictator which controls all the aspects of their citizens lives. In practice the term is often is used to describe a political situation where a small group of people, or one organization, has total authority over a nation. In Hitler's Germany there were many characteristics of a Totalitarian state and a Totalitarian Dictatorship. The Government ran and censored the media. All forms of communication were liable to interference from above and could, and were, heavily censored. This removes freedom of speech, therefore enabling the government to influence popular opinion via propaganda and false news messages. The Age of Anxiety, the age of the lost generation, was also an age in which modern Fascism and Totalitarianism made their appearance on the historical stage. Before examining if Hitler established a totalitarian dictatorship, it is necessary to look at how Hitler, once in power, established a dictatorship. In my essay I will be examining three different methods of control, one how Hitler manipulated the law, two how Hitler used terror and three how Hitler used propaganda and persuasion. Hitler used the law to his own advantage throughout his quest to become the Fuhrer and when he eventually became the Fuhrer. Hitler removed his opposition through the Enabling Act. The Enabling Act gave Hitler the power to

The effect of sucrose solution concentration On osmosis in potato chips

The effect of sucrose solution concentration On osmosis in potato chips Plan I am going to cut six pieces of potato using a borer. They will all the same weight. I will make them all 0.7g. I will be able to make sure they are all the same weight-using scales. If a piece of potato is too big I will use a scalpel and a tile to trim it so they are all the same weight and then place these into a test tube each. I will hold the test tubes in a test tube rack. Using the measuring cylinder I will measure 10ml of each strength of sugar solution rinsing the measuring cylinder after each measure. This will then be added into separate test tubes with the pieces of potato. E.g. a piece of potato will have 0.0M strength; a piece of potato will have 0.2M strength and a piece of potato will have 0.4M strength etc. I will put a sticky label on each test tube stating what strength of sugar solution it contains. I will then leave these for 2 hours and see what happens then record my results. APPARATUS A potato Sugar solutions (0.0, 0.2, 0.4, 0.6, 0.8, and 1.0) Borer Scalpel Tweezers Scales 6 test tubes Test tube rack Measuring cylinder I will measure the amount of sugar solution in the test tubes. I will change the strength of sugar solution in each test tube. To make the experiment a fair test I will keep the weight of the pieces the same weight I will also only add the same

Effect of enzyme concentration on initial rate of reaction

Effect of enzyme concentration on initial rate of reaction The objective of this experiment is to determine how differentiating the concentration of the enzyme catalase affects the initial rate of reaction, in the decomposition of Hydrogen Peroxide (H2O2) The equation of this reaction is: Hydrogen Peroxide(aq) --> Water(l) + Oxygen(g) 2H2O2(aq) + catalase(aq) --> 2H2O(l) + O2(g) The source of the enzyme Catalase in this experiment will be yeast, specifically the Saccharomyces Cerewisea strain, as it is easy to obtain and very safe with no harmful effects to the environment. The technique used to obtain a set of results will be the downward displacement method, where evolved oxygen product from the reaction is passed through a delivery tube and into a water filled burette, pushing the water out of the burette, leaving obtainable results of Oxygen collected. These results will be taken every 5 seconds for two minutes and will give the rate of reaction. My Equipment will be: * Burette * Side-arm Conical Flask * Bung * Tubing * Yeast * Hydrogen peroxide * Water Bath * Water/Margarine Tub * Distilled water/pH7 buffer * Stopwatch I chose to have a burette to collect the evolved Oxygen, as it has a great degree of accuracy. The gas can be measured to 0.05ml or 0.5cm3. I chose to have a side arm conical flask to provide a source for the evolved oxygen to travel

Blues Music

Blues Music Blues Music began as songs sung by black slaves in the mid - 19th century in the Southern United states. It has taken elements from African, European and American folk music. After the Civil War and emancipation the Blues spread, together with the species that sang and played it, from the cotton fields of the southern states to northern cities such as Chicago and Detroit, where the music became hugely popular. The notes in the blues scale are very dissonant. This may be because the black slaves were in misery working all day, and the scale represents their feelings. In the scale of C, the notes in the blues scale are: ______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ This is the chord sequence in 12-bar blues music. It is still sometimes heard in popular music today. Chord of Chord of Chord of Chord Bars 1 - 4 C C C C Bars 5 - 8 F F C C Bars 9 - 12 G F C C Blues music has many characteristics in its melody that makes it typical to the style. It often rolls between 2 notes, and sometimes there is a glissando, which is sliding from one note to another. Blues music may also

Importance of Water.

Importance of Water Our Earth seems to be unique among the other known celestial bodies. It has water, which covers three-fourths of its surface and constitutes 60-70 wt % of the living world. Water regenerates and is redistributed through evaporation, making it seem endlessly renewable. So why worry? Actually, only 1% of the world's water is usable to us. About 97% is salty sea water, and 2% is frozen in glaciers and polar ice caps. Thus that 1% of the world's water supply is a precious commodity necessary for our survival. Dehydration (lack of water) will kill us faster than starvation (lack of food). Since the plants and animals we eat also depend on water, lack of it could cause both dehydration and starvation. The scenario gets worse. Water that looks drinkable can contain harmful elements, which could cause illness and death if ingested. Good water is essential to body cleansing. It's obvious. It sounds like a truism. Your body goes down fast without water. Making up almost three-fourths of the body, every cell is regulated, monitored and dependent on an efficient flow of water. Not one of the processes in our bodies could take place without water. Water is something that we take for granted. But how many of us really understand how essential water is or what happens to our body if it doesn't receive pure water every day, free of chemicals and

Agricultural Issues: Genetic Modification.

Agricultural Issues: Genetic Modification Scientists are developing ways to make new genetically modified (GM) food that could transform the way we feed ourselves. GM crops may enable more food to be produced from less land using less water and fewer chemicals. However, some people question whether this "gene revolution" will really reduce hunger in the world. Others worry that it is being pushed too quickly without enough consideration of its long term impact. Throughout the world there are drastic inequalities in food supply with the emergence of areas of surplus and famine. The cause of such inequalities vary from physical to human and political. Most of the responses to these problems have been driven by high income, high technology MEDC's or trans-national companies. The impacts of the Green Revolution, intensification of farming and the development of genetically-modified foods have varied. Some are economic while others have been social or environmental: some have brought benefits, while others have created problems and some may be focused upon the environment e.g., organic farming. Throughout the world genetic modification has been used freely for more that a decade as a research tool for medical purposes and in food ingredients. It holds exiting promise, not only for conquering disease, eliminating pests and contributing to the knowledge economy but for enhancing
