Based on your experiences, identify one (1) example of a business function / operation. Explain the business function / operation in the context of business data models. Identify the business rules associated with your selected business function / operation. Explain the manner in which such business rules would impact the design of a database. Explain at least one (1) way in which the business function or operation would be affected if these business rules were not adhered to in the development of the database. CIS 111 Week 2 Discussion "Relational Database Model" Please respond to the following: In the Week 1 discussion, you identified one (1) example of a business function or operation and the business rules associated with that business function / operation. You will build upon that discussion as you describe the main entities or objects of that

2 business function / operation in question, as well as the manner in which they relate to one another. Describe the main entities or objects of the business function / operation. Specify the attribute that would be the primary key for each entity, and provide a rationale for why you selected such an attribute. Determine whether the relationships between each of the chosen entities are oneto-one, one-to-many, or many-to-many relationships. Justify your response. Explain the key manner in which the business function / operation and the business rules associated with that business function / operation support the relationships mentioned above. Also, explain the fundamental ways in which the relationships could change, based on the interpretation of the given business rules CIS 111 Week 2 Assignment 1 Business Rules and Data Models Due Week 2 and worth 100 points Suppose a local college has tasked you to develop a database that will keep track of students and the courses that they have taken. In addition to tracking the students and courses, the client wants the database to keep track of the instructors teaching each of the courses. Use the internet to research the types of information that a college would want to track in a database. Focus your attention on information that could represent entities within a database as well as attributes of such entities. Write a two to three (2-3) page paper in which you: 1. Describe the purpose of the database. 2. Based on your research and / or common knowledge of a college and the information tracked by a college, describe the entities of the database and the attributes of each entity. 3. Based on your research and / or common knowledge of a college and the information tracked by a college, describe the business rules that could impact the structure of the database.

CIS 111 Week 3 Discussion "Entity Relationship Modeling" Please respond to the following: As explained throughout this course, entity relationship modeling is a critical element of database design. If the database is not properly modeled, it is unlikely that the database will be properly developed. Using this knowledge, explain the key reasons why entity relationship modeling is important, and determine at least (1) way in which it impacts the overall development of the database. Analyze the key ways that entity relationship modeling helps database developers overcome potential design challenges and conflicting goals.

10 Use technology and information resources to research issues in database systems. Write clearly and concisely about relational database management systems using proper writing mechanics and technical style conventions. CIS 111 Week 5 Midterm Exam Question 1 exists when different versions of the same data appear in different places. Question 2 A is a logically connected set of one or more fields that describes a person, place, or thing. Question 3 The structure is quite different from that of an operational or transactional database. Question 4 relates to the activities that make the database perform more efficiently in terms of storage and access speed. Question 5 End-user data is. Question 6 data exist in a format that does not lend itself to processing that yields information. Question 7 is the body of information and facts about a specific subject. Question 8 is used to reveal the meaning of data. Question 9

11 Students and classes have a relationship. Question 10 A(n) is bidirectional. Question 11 The data model uses the concept of inheritance. Question 12 A(n) enables a database administrator to define schema components. Question 13 In the model, each parent can have many children, but each child has only one parent. Question 14 In the model, the user perceives the database as a collection of records in 1:M relationships, where each record can have more than one parent. Question 15 are important because they help to ensure data integrity. Question 16 A verb associating two nouns in a business rule translates to a(n) in the data model. Question 17 In the context of a database table, the statement A B indicates that if you know the value of attribute A, you can look up the value of attribute B. Question 18 A is any key that uniquely identifies each row. Question 19

12 A(n) is an ordered arrangement of keys and pointers. Question 20 combines all rows from two tables, excluding duplicate rows. Question 21 The constraint can be placed on a column to ensure that every row in the table has a value for that column. Question 22 In the relational model, are important because they are used to ensure that each row in a table is uniquely identifiable. Question 23 The relationship should be rare in any relational database design. Question 24 Any attribute that is part of a key is known as a. Question 25 The Crow s foot symbol with two parallel lines indicates cardinality. Question 26 A derived attribute. Question 27 Knowing the number of entity occurrences is very helpful at the application software level. Question 28 An entity is said to be -dependent if it can exist in the database only when it is associated with another related entity occurrence.

13 Question 29 A relationship exists when two entities are associated. Question 30 relationships are most common. Question 31 The M:N relationship between STUDENT and CLASS must be divided into two 1:M relationships through the use of the ENROLL entity; the ENROLL entity is. Question 32 A should be a derived attribute. Question 33 Normalization works through a series of stages called normal forms. For most purposes in business database design, stages are as high as you need to go in the normalization process. Question 34 The most likely data type for a surrogate key is. Question 35 Before converting a table into 3NF, it is imperative the table already be in. Question 36 An atomic attribute. Question 37 A table that is in 1NF and includes no partial dependencies is said to be in. Question 38 Normalization represents a micro view of the within the ERD.

14 Question 39 A table that has all key attributes defined, has no repeating groups, and all its attributes are dependent on the primary key, is said to be in. Question 40 A relational table must not contain a(n).
