This document contains instructions and questions for a database systems exam. It is divided into two sections: Section A contains 40 multiple choice questions, and Section B contains two structured questions. The first question in Section B asks students to define database schema architecture and relational data model terms. It also asks students to generate outputs using relational operators. The second question asks students to explain concurrency control problems and draw an ER diagram based on a scenario about a bakery's products and orders. It also contains sample SQL queries to test students' skills.
Database normalization is the process of structuring a relational database in accordance with a series of so-called normal forms in order to reduce data redundancy and improve data integrity. It was first proposed by Edgar F. Codd as part of his relational model.

Phase 1- Database Design and DDL
I contracted to design and develop a database for CTU that will store individual and confidential university data. This database is required to give the back-end engineering to a front-end web application with an instinctive User/Interface (U/I) to be utilized by the college HR office. We've chosen to utilize Microsoft SQL Server 2012 given the way of information to be put away because it will be more secure, and it additionally gives a suite of server upkeep apparatuses to be deserted with the IT Department once the database and web application have been tried and acknowledged by college partners.
Amid our preparatory gatherings, CTU's necessities were characterized and enough perused to start making of the database. The accompanying areas contain the business tenets and element tables created amid the preparatory gatherings, and additionally duplicates of all the SQL code used to manufacture the database and make the Entity Relationship Diagram (ERD).
Business Rules & Entity Tables
Business Rules:
· A student has a name, a birth date, and gender.
· You must track the date the student started at the university and his or her current GPA, as well as be able to inactivate him or her without deleting information.
· For advising purposes, store the student's background/bio information. This is like a little story.
· An advisor has a name and an e-mail address.
· Students are assigned to one advisor, but one advisor may service multiple students.
· A class has a class code, name, and description.
· You need to indicate the specific classes a student is taking/has taken at the university. Track the date the student started a specific class and the grade earned in that class.
· Each class that a student takes has 4 assignments. Each assignment is worth 100 points.Entity Tables:

Assignment 1 LASA 2 Implementing Six Sigma at Wishmewell Hospita.docxsherni1
Assignment 1: LASA 2: Implementing Six Sigma at Wishmewell Hospital
Emergency departments (ED) at many hospitals have been overwhelmed in the past year, as more patients without health insurance use the ED as a primary care solution. Wait times in the ED are increasing as more and more Americans are using the Emergency Department for their general health concerns. Across the country, the average ED wait time is now 222 minutes (approximately 3 hours, 42 minutes).
Wishmewell Hospital's average wait time in the ED is more than five hours, and the board of directors is concerned about this long wait time. The danger is that a patient's condition may escalate during his/her waiting time in Wishmewell's ED.
The board has tasked you to take on a new quality improvement initiative to decrease wait time in the ED using the Six Sigma approach.
Develop a quality improvement program using the Six Sigma approach to decrease waiting time in Wishmewell's emergency department.
The quality improvement program must include the following elements in an approximately 10-page MS Word document:
· Describe the goals and objectives of your plan to decrease ER wait times at Wishmewell.
· Describe each step of the Six Sigma (DMAIC) process:
· Define the problem
· Measure the process; what Six Sigma tools will you use?
· Analyze the data; what tools will you use to analyze the data?
· Improve the process; explain your improvement plan
· Control; how will you continue to monitor the results and adjust as necessary?
· Describe the key players (stakeholders) who should be members of your implementation team and explain why teamwork is an important factor in implementing a quality improvement program.
· Explain at least three factors that might inhibit the implementation of your decreased wait time program.
Submit the quality improvement program plan to the M5: Assignment 1 Dropbox by Saturday, November 2, 2013.

Phase 1- Database Design and DDL
My team was recently contracted to design and develop a database for CTU that will store personal and confidential university data. This database is expected to provide the back-end architecture for a front-end web application with an intuitive User/Interface (U/I) to be used by the university HR department. We’ve decided to use Microsoft SQL Server 2012 given the nature of data to be stored because it will be more secure, and it also provides a suite of server maintenance tools to be left behind with the IT Department once the database and web application have been tested and accepted by university stakeholders.
During our preliminary meetings, CTU’s requirements were defined and adequately scoped to begin creation of the database. The following sections contain the business rules and entity tables developed during the preliminary meetings, as well as copies of all the SQL code used to build the database and create the Entity Relationship Diagram (ERD). Business Rules & Entity Tables
Business Rules:

There are many departments within each store, for example, HR, accounts, finance and sales etc. each department is uniquely identified by department number. AMC also records department title, phone number and email address.
Each store has a number of employees. Each department is supervised by a department supervisor and each store is managed by a store manager who both are employees of AMC. Each department has a single supervisor only i.e. the department supervisor is also the supervisor for all the employees work within that department.
Each employee is referenced by unique employee number, name (first and last names), address, mobile number, email, TFN, salary and joining date. An employee’s salary is recorded differently as per his or her employment type. Employees can be employed as fulltime or casual basis. For a fulltime staff, annual salary is recorded and hourly rate for a casual staff.
Each store creates payslips for all employees work in that store on a weekly basis. As a minimum payslip number, no of hours worked, employee detail, store detail and gross pay are recorded.
AMC sales different products like fashion, health, beauty, electronics etc. Each product is characterised by product number, name, brand, description and price.
Each product can be supplied by one or more supplier and each supplier can supply one or many products. AMC also keeps appropriate details of their suppliers.
Each store maintains an inventory of their products available for sale. The quantity of each product available in store and the quantity ordered are kept.
AMC patron visits the store and shops in the store. Each customer is characterised by customer number, name (first and last names), mobile number and address.
A patron may place orders. An order contains one or many products at a time. A store keeps track of order number, order date, product(s) ordered and quantity ordered for each product.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
