Data Base

Tracy Kidder conveys the historic computer development competition between Digital Equipment Corporation (DEC) and Data General in The Soul of A New Machine mainly through chronological events; however, he refers to past events to delve deeper into his point and prove his conclusions. While Kidder tries to deliver the story mainly through a neutral perspective, he tends to reveal Data General’s side of the story with a focus on its employees’ stories causing a slight bias towards Data General. Kidder continuously references “some years back” (Kidder 23), revealing that he may be looking back and analyzing the events that occurred. His focus is also primarily on the events that occurred and the people that influenced them; thus, Kidder briefly mentions the exact year of each event by passing over it with short syntax: “It was 1976” (Kidder 35). In addition, Kidder tangents off to flashbacks of previously mentioned events or situations that occurred significantly before the

1) Accurately describe the source contents. Be as specific as possible. The September 11, 2001, Documentary Project is a collection of reactions, eyewitness accounts, and opinions expressed by Americans and others in the months following the September 11 terrorist attacks on the World Trade Center, the Pentagon, and United Airlines Flight 93. The collection is comprised of 200 audio and video interviews, 45 graphic items such as photos and drawings, and 21 written narratives. 2) What things make this document significant and worthy of someone else's attention? Tell us everything you can think of that makes this document important. The September 11, 2001, Documentary Project is important because it illustrates the political climate that led the nation into a war against a nation-less enemy, which had been termed the "War on Terror." The reactions demonstrate the feeling of deep fear and insecurity prevailing amongst many Americans, who were not accustomed to seeing foreign threats on American soil. 3) Who is the audience(s)? What goal(s) was the author seeking to accomplish? What were his/her major points? What didn't the author say that might have been included? Being a collection gathered by the National Library of Congress, the intended audience is the general American public. It was gathered in order to create a record of American public opinion at the time of the September 11 attacks. 4) Place the source into its

3) Which of the following statements is true about naming a new database in Microsoft Access?

A database schema is built and used to group objects logically in a table and sorted into views and process procedures. A schema is somewhat of a box that contains the objects used in the database. Providing security for a database schema can be a task. To create a database schema the user will use SQL server

In this paper the writer will seek to respond to the questions designated for both scenarios. This paper will list typical fields for each type of data. Provide an example of two relationships that you need to track. This paper will also answer the questions of: Do you need a database system? If not, can Excel® handle the data and the output? What are the advantages and disadvantages? Would you use a personal database or an enterprise database? Explain your answer. Would a decision support system (DSS) be helpful? Explain your answer.

▪ The attribute that is used to derive the attribute is called a stored attribute.

Relationships on a database establish a connection between two associated and logically related tables, that each have similar data. An example may be a table that contains names of certain students, and another table that contains the student's ID, the code of library books, and the dates on which each specific student checked out that particular library book. Without association of relationship on the relational database, the two tables would be independent figures with librarian lacking a method for associating student with his/ her item. The library, accordingly, would have to close down in a short period of time. The database connection, on the other hand, allows a connection to be drawn between the Student's table and the Student's instrument table (that represents the books that the student checks out).

Table –this is where data is stored for processing and output .The table is defined as a collection of correlating data consisting of rows and columns. For example, the CUSTOMER or PURCHASES table may entail the customer first name, last name, address and the product that the customer purchased or wishes to purchase.

Following table shows the number of data tables, queries and forms which shows the complexity of the current database.

The language used for creating the database can create its own tags so it is easier to use

This Schema type on uses attributes and elements and follows a hierarchy in structure type. It is very simplistic and uses few attribute definitions, and does not follow XML type syntax. However, despite its simplistic nature, it is the most widely used standard according to Lee and Chu (2000).

Building a data base is IMPERATIVE to building a business. This needs starts with "The owner’s daily schedule". Most centers have an average of 2500-3000 businesses around them, and YOU need to visit all of them eventually. The sooner the better, by setting out in an organized Manner this can happen in 2-3 months, building your business at the same time.

• DBMS models real world • Data Model is link between user’s view of the world and bits stored in computer • Many models exist • We think in terms of..

SQLite supports the data types TEXT (similar to String in Java), INTEGER (similar to long in Java) and REAL (similar to double in Java). All other types must be converted into one of these fields before getting saved in the database. SQLite itself does not validate if the types written to the columns are actually of the defined type, e.g. you can write an integer into a string column and vice versa.

What is DBMS? -Data base management Systems-This is a collection of computer processes which can be software, or firmware. A generalize or specialized computer is used to run this system. The DBMS uses a language or device to: Define the logical database of a specific database directly or through IRDS. (information resource dictionary system). Define the physical component, specify interrogations, and specify system control. (Gorman, 2015)
