Figure 2. The relationship diagram of the NorthWind database. a. Use the ERDPlus tool to design a STAR schema of the data warehouse containing one fact table and four dimension tables. Your dimension tables should include one location dimension and one time dimension. Each dimension table must have a key attribute and at least one other attribute. Attach a screenshot of ERDPlus. b. Give an example of an OLAP analysis involving location and time dimensions.

Question a. Normalization is an important concept for database professionals. Whether you are the designer, database analyst or administrator, it is useful for designing, situation verification as well as performance tuning. In your opinion discuss the basic issues to be aware of before carrying out the normalization process. b. Given the following relational schema and its functional dependencies: Rentallnfo custNo propertyNo custName pAddress rentStart ownerNo OName fd1 fd2 fd3 fd4 fd5 Specify candidate keys and state the primary key. Assuming that the relation is in first normal form (1NF), describe and illustrate the process of normalizing the relational schema to second (2NF) and third (3NF) normal forms. Identify the primary and foreign keys in your third normal forms. ii.

Indicate the changes (using the shorthand representation) that you would need to make to the original KimTay Pet Supplies database design to support the following requirements. There is no relationship between customers and sales reps. When a customer places an order, any sales rep can process the order and create the invoice. On the invoice, you need to identify both the customer placing the order and the sales rep responsible for the invoice. Draw an E-R diagram for the new design.

Martex Inc. is a manufacturer of athletic equipment and its primary lines of business include running, tennis, golf swimming and basketball. Martex currently supplies four primary vendors including Sam's sports, Total Effort, and The Underline. Martex wants to build a database to help it organize its products. In a group, identify the different types of entity classes, and the related attributes that Martex will want to consider when designing the database.

Consider the unnormalized data presented in the STUDENT table below:a) Identify the data redundancies and give reasons why they create problems in schemas.

Based on BITS database user views as designed in Your Turn 6-1 in this chapter. In each exercise, represent your answer in DBDL and with an Entity Relationship Diagram.  2. Indicate the changes you need to make to the design of the BITS database to support the following situation.  There is no relationship between clients and consultants.  When a client places an order (service request), it may be performed by any consultant.  On the order, identify both the client placing the order and the consultant responsible for the order.

All of you must be familier with human resources system (employee database). Soplease design database for a human resources system that at least has 4 entitiesinvolved and for the 4 entities please do the following:a. Create the tables that conform to 3NF.b. Draw the Crow’s Foot ERD to reflect the dependency and relationshipdiagrams;c. For all entities/tables created please write the MASTER and TRANSACTIONdata accordingly!d. Use SQL commands to to do selection which involve 1 table, 2 tables, and 3tables.

I want to create logical database design:          1. Normalize the relations to at least third normal form (3NF) using proper standard E-R diagram notation. Provide the appropriate relational schema reduction.           2. Identify the primary and foreign keys for each relation (using appropriate notation). Maybe either list the primary and foreign keys or generate a schema diagram???          3. Identify and describe any indexes needed to speed up searches on non-key attributes – can you explain it too? So I would understand why you come up with the answer please?          4. Identify and describe unique, conditional (check), non-null, referential integrity, or other constraints needed to guarantee the integrity of the database. 5. Describe the set of business or workflow rules applicable to your project. Next, describe at what point in the workflow you will implement the business or workflow logic and the justification for doing so.Below are my conceptual design.

7. In the context of database design, consider the following scenario: There is database table that contains columns for employee ID, employee name, department, department location, and project details. Upon analyzing the table, you notice that there are multiple rows with the same employee name, department, and department location, but different project details. Based on this scenario, which of the following best describes the normalization process that should be applied to improve the database design? A) Split the table into two: one containing employee ID and employee name, and the other containing department, department location, and project details. B) Combine all columns into a single table to reduce redundancy. C) Normalize the database to the third normal form by creating separate tables for employee details, department details, and project details, and establish relationships between them. D) No action is required as the table already follows the normalization principles.

Hi, I could use help on making ERD's for this problem. It needs to be crows-foot notation. It must have entities, attributes, relationships, cardinalities, primary keys, and foreign keys. Please break this down so I can make sure I understand. Here is the description: Marsha Mobley, the manager of the ACME Anime Shop wants you to design a database system that will enable a number of tasks. One problem that Marsha has is keeping track of inventory. Several times a week the store receives shipments from various vendors. Marsha would like a system that can record these shipments. Most of the shipment information originates with an order to the vendor.Marsha currently records order information on an order form, which is shown below, along with the form currently used to record inventory. When shipments arrive, Marsha wants the system to indicate that the order has been received. More importantly, Marshaneeds the system to update the store inventory. The system should also record basic…
