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?
The following exercises are based on the 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.
5. Indicate the changes you need to make to the BITS database design to support the following situation. The client address may or may not be the same as the Bill To address on the client's invoice.
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

Which tactic do you think is the best, and why do you think it's the best?arrow_forwardYou have been hired as a Database Developer and you have been given the option to use a trigger and a procedure. Discuss what triggers are and when it would be best to use them?arrow_forwardQuestion 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.

- 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.

You will add to your report a listing of the CREATE TABLE statements. Specify as many constraints (key, referential integrity) as you can in the relational schema. You should state the choices you made during the EER-to-relational mapping, and the reasons for your choicesarrow_forward
- Topic: Database Design It is known that can use the DBMS system to create a surrogate primary key when there is a natural key. 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_forwardhe following tables form part of a database held in a relational DBMS:Hotel (hotelNo, hotelName, city) Room (roomNo, hotelNo, type, price) Booking (hotelNo, guestNo, dateFrom, dateTo, roomNo) Guest (guestNo, guestName, guestAddress) • where Hotel contains hotel details and hotelNo is the primary key;• Room contains room details for each hotel and (roomNo, hoteINo) forms the primary key;• Booking contains details of bookings and (hoteINo, guestNo, dateFrom) forms the primary key;• Guest contains guest details and guestNo is the primary key.a) Identify the foreign keys in this schema.

Relational database management systems (RDBMSs) enforce integrity rules automatically, but it is much safer to make sure your application design conforms to the entity and referential integrity rules.
