...Principles of Database Management Systems Homework 1 Ying Li 4861521 Homework 1 Exercise 1.4 Explain the difference between external, internal, and conceptual schemas. How are these different schema layers related to the concepts of logical and physical data independence? Answer: External schemas, which usually are also in terms of the data model of the DBMS, allow data access to be customized (and authorized) at the level of individual users or groups of users. Internal (physical) schemas summarize how the relations described in the conceptual schema are actually stored on secondary storage devices such as disks and tapes. Conceptual (logical) schema describes the stored data in terms of the data model of the DBMS. In a relational DBMS, the conceptual schema describes all relations that are stored in the database. Any given database has exactly one conceptual schema and one internal schema because it has just one set of stored relations, but it may have several external schemas, each tailored to a particular group of users. External schemas provide logical data independence, while conceptual schemas offer physical data independence. Exercise 1.6 Scrooge McNugget wants to store information (names, addresses, descriptions of embarrassing moments, etc.) about the many ducks on his payroll. Not surprisingly, the volume of data compels him to buy a database system. To save money, he wants to buy one with the fewest possible features, and he plans...

...Homework #2 – Excel Charts and Pivot Tables Overview and Learning Objectives This homework assignment asks you to use Microsoft Excel to use the VLookup function in a report, and also to generate charts and pivot tables. These are all useful skills. VLookup simplifies spreadsheet logic in many situations, and charts offer a visual perspective that can help people to see trends and data relationships. And once you get the idea of pivot tables, they are extremely useful in summarizing data “on the fly” in a variety of formats. This assignment is related to course objective #4 (“Design and implement Microsoft Excel spreadsheets and Microsoft Access databases to support business decision making”). Quality Furniture Enterprises, Continued This homework assignment continues the scenario from Homework #1, about Quality Furniture Enterprises. Caitlin’s uncle (and boss) was pleased with the sales forecast report she created. “I guess I should learn Excel,” he says. “I’ve been using the calculator on my laptop to compute the totals, and then copying and pasting things into a Word document.” Caitlin did her best not to appear smug, but it was nice to be appreciated, especially since this was still her first month on the job. But before she had any time to bask in her success, her uncle said, “And since you did so well on that report, I have another project for you.” So much for taking an early lunch break today. “Sure,” she said. “What do you need?” “First off, remember how I told...

...Unit 8 Homework Unit 8 Assignment 1 DNS is a server based distributed database management system that translates domains host’s names to IP Addresses. It also allows a computer host or a client to use words instead of numbers to request information from a server or a client. You can get words or numbers to get the information from servers. Unit 8 Assignment 2 In Windows NT, when you make a change to the Security Accounts Manager, the change is applied directly to the Primary Domain Controller and is later replicated to each Backup Domain Controller. In an Active Directory multi-master replication environment, each domain controller contains a copy of Active Directory, not just the information for a single domain. When a change is made to Active Directory, the change is applied to whatever domain controller is the closest, and is then replicated to the remaining domain controllers. This prevents a designated Primary Domain Controller from being overburdened. Centralization sums up a primary reason for implementing Active Directory. The Active Directory structure makes it possible for you to achieve truly centralized management of users, regardless of how big the client’s network has become. In Windows NT a domain is a completely independent entity, and while it's possible to create a trust relationship between domains that exist on a common network, the domains are never truly integrated with each other because there is no higher authority that manages the domains. The domain...

...Running head: Asperger’s Syndrome Asperger’s Syndrome Cynthia Brownlee Eng 101 October 30, 2011 Abstract Asperger Syndrome (AS) is a relatively new disability to the United States. The awareness of the disability is about twenty years old. However, the increase of the number of individuals being diagnosis is rapidly growing. This paper defines the characteristics of an AS individual and provides information for educators as far as strategies and accommodation needed to make the classroom successful. The education arena holds the responsibility of learning strategies and interventions in assisting an individual with AS. Asperger’s Syndrome According to Lee and Park (2007), “‘Autistic psychopathy’ (as cited in Asperger, 1944, p.76) was the first term used to describe Asperger’s Syndrome” (p. 132). In 1943 the condition of autism was discovered by Dr. Leo Kanner. His description of autism reflects the lack of involvement of children socially with other people, but reflects the consistency of routines and differences in mannerisms. In 1944 Dr. Hans Asperger, who was unknowing of Kanner’s work with autism, introduced children with a milder form of Autism. He published his work; however, the audience of the research was very limited. Asperger revealed in Asperger’s Syndrome (AS) when his works were published in Germany. The United States was not introduced to this disability until...

...ANTHROPOLOGY 101 Introduction to Cultural Anthropology Queens College / CUNY, Spring 2015 TuTh 12:15-1:30PM, Kiely 150 Professor: Ramona Lee Pérez, PhD Email: ramona.perez@qc.cuny.edu Office hours: Th 2-3 PM, PH 315H COURSE DESCRIPTION This course is an introduction to the range of human diversity through an exploration of the peoples of the world. We will cover the basic concepts, theories, and methods that anthropologists use to study variations in cultural norms and social practices, economic systems and rules of law, social organization and patterns of inequality, identity and worldview, and patterns of social and cultural change. Focusing on the culture concept and the method of ethnography, we begin with the historical foundations of anthropology and then follow its attempts to understand contemporary human cultures. Comparative analysis of multiple ethnographic case studies and major theoretical approaches illuminates the range of human diversity, the forces that shape cultures, and how people adapt to a rapidly changing modern world. The central objectives of this course are to develop your intellectual skills, your cross-cultural fluency, and your sense of civic and moral engagement in global society. I hope that this course inspires many of you to become anthropology majors or minors, and grants each of you an anthropological perspective on your own life. REQUIREMENTS This is an intensive course that requires full participation from every student...
