Data Dictionary and Normalization Guidelines The purpose of a data dictionary is to define the objects and data within an organization's database management system. This metadata does not contain any of the database's data, but only information about the structure, storage and use of the database's data. A data dictionary can be stored in files or documents, or can be stored within a database in the DBMS. For example, a database may contain an employee table that has an emp_no column and an identification_no column. A data dictionary can explain that the emp_no column is an integer value containing the employee number assigned by the system. When a new employee is added to the system, a next number value is retrieved from a next number table and assigned to the new employee record. The data dictionary would also explain that the identification_no column is an alpha-numeric value that contains the employee's social security number for US residents and for non-US residents contains the employee's country code followed by their work visa number.
For example, consider a patient who is in an emergency situation and he is brought to Sinclair hospital by means of the ambulance, information about the patient will be recorded following a number of steps. Typically the patient will be received from the ambulance and a nurse will enter the heath data of the patient into electronic records document. As the patient continues to be seen by other health providers e.g. physicians, their health data will be recorded in electronic health care data. The computer in turn will build the data record of the patient. Assuming that the patient had been admitted in the facility sometimes ago, these will have a unique record number that will always be assigned to that patient. Apart from this unique code, the patient will also be given an account number which will be different in all encounters. The essence of using different account numbers will be to facilitate group charges. For example, consider a patient who had been admitted a week ago with malaria, he will be given an account on that day. A week after, if he is admitted to the same facility with a different kind of illness say allergic reactions he will be given a different account with same unique code. When finding the charges of the patient it will be in form of groups since it represents different
How would you define standardized terminologies and why are they important? Provide an example in your answer.

What does it mean to be a “teen mom”? People can put others into groups and to some degree label them without even consciously thinking about it. There are even television shows about this topic including, “Sixteen and Pregnant” and “Teen Mom”, at times these shows show the affect the situation has on the father as well. Some individuals say this idolizes this situation, others say it shows a realistic picture of what life would be like to be a mom at 16. This is something that people may categorize or label as soon as they see or assume someone is a “teen mom”. This label may end up having a negative effect on the parent(s). To many people this can be a sign of irresponsibility or poor judgment, but obviously everyone in this situation is not the same. Some are irresponsible and do not change; but some do take on the responsibility and change themselves to become a better person and a more responsible parent.
One of the biggest problems that affect everyone is data aggregation. The more the technology develop, the powerful and dangerous it gets. Today there are many companies that aggregate a lot of information about us. Those companies gathering our data from different sources, which create a detailed record about us. Since all services have been computerized whether it is handled directly or indirectly through computers, there is no way to hide your information. We used computers, because they are faster, better, and accurate more that any human being. It solved many problems; however, it created new ones. Data does not means anything if it stands alone, because it is only recoded facts and figure, yet when it organized and sorted, it become information. These transformed information. Data aggregation raises many questions such as, who is benefiting from data aggregation? What is the impact on us (the users)? In this paper I will discuses data aggregation and the ethics and legal issues that affect us.
A database is a structured collection of data. Data refers to the characteristics of people, things, and events. Oracle stores each data item in its own field. For example, a person's first name, date of birth, and their postal code are each stored in separate fields. The name of a field usually reflects...
The topic for this essay is about the United States, may or may not change their measuring system from English to Metric. There are four countries that use the English system for measuring objects. The four countries are the United States, Alaska, Liberia, and Myanmar (Burma). The countries that use the English system think they should just keep their system. The countries that use the Metric system think that everyone should use the Metric system.
For example, each row of a spreadsheet may store information about a car that Sutton Dealership will sell. Each column may store a different aspect of the car's information, such as model, make, colour, engine size, etc. The spreadsheet software can analyse this data by counting the number of people who purchased car with 2.0 litre engine size, listing all the people who purchased white cars, or performing other calculations. This makes spreadsheets similar to database.

Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
Standardization of the English Language There are several important events before 1500 that, when listed together, show a series of steps in the struggle for English language supremacy. These steps are mainly governmental, legal and official events that pushed English usage. In 1356 The Sheriff's Court in London and Middlesex were conducted in English for the first time. When Parliament opened in 1362 the Statute of Pleading was issued declaring English as a language of the courts as well as of Parliament, but it was not until 1413 that English became the official language of the courts everywhere. Thirteen years later in 1423, Parliament records start being written in English.
