For the purpose of illustrating the structure of a database, either an E-R diagram or DBDL may be used. If that's the case, which strategy do you favor, and why?
Using the relations that I attached, defined and normalized, create the SQL DDL statements necessary to implement database schema as an OpenOffice database. You may also implement your database in MySQL, IBM DB2 Express, Microsoft Access, SQL Server if you have access to these database systems. The answer should include a document that contains all of the SQL statements that you created and a screenshot that shows the structures that you implemented in the database of your choice. Your DDL statements must accommodate the following elements:
Create statements to create tables from the entities defined as part of the attachment.
Appropriate use of Null (and Not Null) parameters to ensure data validity
Appropriate use of constraint clauses to implement appropriate referential integrity
Use of data types and formats that is appropriate for the data in your database schema.
Appropriate use of keys including automatic generation of key values if appropriate

Question 2
UNISHOP is a company that manages equipment products,
invoices from their respective vendors and sales representatives
(SalesRep). UNISHOP vendors have been complaining about poor
management of their product handling in the current manual
system. As a result, the top management has decided that
information related to the vendors should be organized using a
DBMS. You have been hired to design the database. Draw an
Entity Relationship Diagram (ERD) to represent the database based
on the requirements given below:
· An Invoice is used to keep track of the Product manage by
SalesRep.
customerName, customerAddress and customercity. The
invoice is uniquely identified by its unique invoiceld. The
invoice is written by only one salesrep but a salesrep may
write zero or many invoices
· SalesRep stores information about SalesRepID, SalesRepName
and SalesRep Tel.
· SalesRep manages the products. The Products store information
such as ProductId, Productname, ProductInfo, SalesReplD and…

What implications does this have on the DB performancewhen searching the table for a specific column (such as ROOM). Hint: When the table is created, the DBMS setups the table to be able to search on the primary key very quickly. What if this Event table was used by a Corporate Hotel chain to keep track of every they have hosted over the past 30 years in all of their hotels across all their chains (i.e. 8000 locations, 5 events a week avg, 30 years of data ~62.4 million events)?arrow_forwardBITS Corporation Exercises The following exercises are based on the BITS database user views as designed in Your Turn 6-1 in this chapter.

A client is not necessarily represented by a single consultant but can be represented by several consultants. 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. 3.

I have an exam coming up, and I'm using the book problems to study. The manager of a consulting firm has asked you to evaluate a database that contains the table structure shown in Table P6.10. (This should be attached). Table P6.10 was created to enable the manager to match clients with consultants. The objective is to match a client within a given region with a consultant in that region and to make sure that the client's need for specific consulting services is properly matched to the consultant's expertise. The following basic business rules are maintained: Each client is located in one region. A region can contain many clients. Each consultant can work on many contracts. Each contract might require the services of many consultants. A client can sign more than one contract, but each contract is signed by only on client. Each contract might cover multiple consulting classifications. Each consultant is located in one region. A region can…arrow_forwardThe following tables form part of a database held in a relational DBMS (Primary Key, Foreign Key): Employee (empNo, empName, empAddress, empGender, empPosition, deptNo) Department (deptNo, deptName, ManagerEmpNo) Project (projNo, projName, deptNo) WorksOn (empNo, projNo, dateWorked, hoursWorked) …where: Employee contains employee details Department contains department details.

The record of train includes its number, name, source, destination, and dayson which it is available, whereas record of train status includes dates for which ticketscan be booked, total number of seats available, and number of seats already booked.Passengers can book their tickets for the train in which seats are available. For this,passenger has to provide the desired train number and the date for which ticket is to bebooked.
