Fundamentals of Managing Data

Data management is creating, organizing, storing and managing the data collected and created by any organization.Effective data management is a crucial part of today's world. Data management provides analytical information on the vast amount of data collected from business applications daily, which helps make critical business decisions and plan and bring out the best strategies.

Question

Consider the ER diagram shown in Figure 3.22 for part of a BANK database. Each
bank can have multiple branches, and each branch can have multiple accounts and
loans.
a. List the strong (nonweak) entity types in the ER diagram.
b. Is there a weak entity type? If so, give its name, partial key and identifying
relationship.
c. What constraints do the partial key and the identifying relationship of the
weak entity type specify in this diagram?
d. List the names of all relationship types, and specify the (min, max) constraint
on each participation of an entity type in a relationship type. Justify your
choices.
e. List concisely the user requirements that led to this ER schema design.
f. Suppose that every customer must have at least one account but is restricted to
at most two loans at a time, and that a bank branch cannot have more than
1,000 loans. How does this show up on the (min, max) constraints?

1. Create an entity relationship diagram for the conceptual design using UML notation. The diagram can be created by hand or via some modeling tool. 2. Create a data dictionary for the entities, relationships and attributes. Make your best guess for representing the attributes. Schema 3 You have been hired by the Snowbird ski mountain resort to build a database for their data. The resort has ski mountain peaks, chair lifts, trails, stores and restaurants. For each mountain peak, you track the name, the elevation and its latitude and longitude. Each peak name is unique. The names of the mountain peaks are: Mount Superior, Mount Baldy, Twin Peaks and Hidden Peak. For each chair lift, you track a unique name, the vertical rise, the travel time, the number of people per chair (ranging from 2 to 4) , and its closing time. For each trail, you track its unique name, its elevation, its length, and the typical time it takes to complete. Each ski trail is classified by its level of…
What does an associative entity model? a.) Associative entities model pure relationships rather than entities. b.) Associative entities model entities that are independent. c.) Associative entities model the real-world scenarios of ways to look up data. d.) Associative entities model attributes and how they are linked to entities.
You have been asked to design and implement a database for CTU, which includes 3 entities (tables), as follows: Students Faculty Courses Part 1 Create a Word document that includes the following: Identify at least 3 attributes for each entity, including the following: Student's entity should have an attribute for the program the student is enrolled in. Faculty should have an attribute identifying their rank. Properly identify all of the primary keys (use solid underlines). Create an entity relationship diagram (ERD) from the entities. You may use SmartDraw, Visio, Erwin, or even Word to draw the diagram. Take a screenshot (no need if you use Word), and insert it into the Word document. Part 2 Use Microsoft Access to implement the database that you designed in Part 1, and include the following: Create the Student, Faculty, and Course tables in Access. Add a few instances in each table. Create 2 queries for the following objectives: Find the student names for all students who are in the…
The Acme Company wants to construct a database to keep track of the company’s employees, departments, and projects as well as the employee’s dependents. Draw the entity-relationship model. The requirements collected to date to be modeled are: The company is organized into departments. Each department has a name, a number, and an employee who manages the department. A department controls a number of projects, each of which has a name, a number, and a start date but not all departments have projects assigned to them. We store each employee’s name, social security number, address, salary, sex, and birth date. Every employee is assigned to a department but may work on several projects, which are not necessarily under the control of the same department. We keep track of the number of hours per week that each employee works on each project. For most projects, a team of employees is assigned to work on the project while some employees are never assigned to a project. We also keep track…
HOMEWORK #6 Consider the following flawed ER diagram representing clubs and their activities. name club Sponsor date time building room activity capacity description A club has a unique ID and a name. An activity has a date, a time, and a description, and is in a room. A room has a unique (building, room number) and a capacity. Each activity is sponsored by exactly one club. 1. Following the rules we studied, convert the ER diagram into a relational schema. 2. The resulting schema is not in BCNF. Identify a non-trivial functional dependency where the left- hand side is not a superkey. 3. Decompose into schemas that are in BCNF. 4. Modify the ER diagram so that it corresponds to the normalized schema and briefly explain what the problem was with the original design.

For each error identified, correct them. Show your corrections either by redrawing the corrected diagram OR by describing how the errors should be corrected next to the circles that you have identified.
(ii) Four entities of the organization are: Worker, Customer, Product and Department. (a) Suggest an identifier, with justification, for any three entities. (b) Describe three relationships that can be inferred from these entities. (iii) Give relational database tables for any two of the entities you used to describe relationships in ii(b). For example STUDENT( StedentMaricule, name, gender, DOB) for the entity student.

Swing Jazz Club ERD Problem Follow the Simple Procedure for ERD diagramming to design an ERD using the following user provided information. Remember the ERD will eventually turn into the design for a database from a top down view. Make sure you resolve any many to many conflicts. Label an identifier or primary key and all pertinent attributes given. If an attribute is not readily apparent from the user information, then make one up that makes sense for the particular entity. Therefore, all entities should end up with at least an identifier and another attribute that makes sense. You may use any of the approaches shown by the book, though the ER-Model and Crow’s foot are the most common. Make sure you show entities, relationships, cardinality, and optionality.
