INSY 3010 Fall 2017 HOMEWORK 6 Due: 12/01/2017 11:00 PM Homework 6 Deliverables • A word document containing the following: • Problem 1 • Desired Queries from Problem 2, Problem 3, and Problem 4 (You do not need to include screenshots of the results of these queries). • Screenshot/Scan of ER Diagram from Problem 3 • Desired Screenshots from Problem 2 and Problem 3 • problem2.sql • problem3.sql Notes • You may work individually or in groups of two students – your choice. • If you work in a group, make sure that both of you submit the exact same zip file on Canvas and indicate your partner in a comment on the assignment. • All files should be zipped into a single file for submission on Canvas (named Homework6_LastName1FirstName1_LastName2FirstName2). • You don’t need to submit any files already on Canvas. (Assume that the TAs have every file provided on Canvas) • We will test your results by running your SQL (.sql) file. Points will be deducted for non-sql files. • ** On problem 2, it is near impossible for two groups to have exactly the same files, since you will be using music of your choice. If found, we may question the authenticity of your work. Please work in complete honesty. 1. (5 pts) List the main steps in database design. What is the goal of each step? In which step is the ER model mainly used? 2. (30 pts) Using the music_with_data.sql file on CANVAS as a template, drop the existing tables and create new tables (preferably with identical names – albums, artists, played, tracks) using music of your choice and implement the new tables in your existing database on acadmysql.duc.auburn.edu. Your database should include at least 25 songs from at least 4 artists and at least 5 albums. Call the file that implements your new music database tables problem2.sql. Include a screenshot of a “select * from tracks” query in your word document. In addition, develop the following SQL queries: • List all tracks in your music database. For each track, display the track name, album name, and artist name fields. • List all albums, along with a count of the total number of tracks on each album. • List all artists, along with a count of the total number of albums associated with each artist. INSY 3010 Fall 2017 HOMEWORK 6 Due: 12/01/2017 11:00 PM 3. The Office of Provost at Auburn University has offered to give you a free lifetime supply of football tickets to home games if you design a database for the employees. Given the rising cost of the tickets, you agree. Heres the information that you gather: • Professors have a bannerID, a name, an age, a rank, and a research specialty. • Projects have a project number, a sponsor name (e.g., NSF), a starting date, an ending date, and a budget. • Graduate students have a bannerID, a name, an age, and a degree program (e.g., M.S. or Ph.D.). • Each project is managed by one professor (known as the projects principal investigator). • Each project is worked on by one or more professors (known as the projects co-investigators). • Professors can manage and/or work on multiple projects. • Each project is worked on by one or more graduate students (known as the projects research assistants). • When graduate students work on a project, a professor must supervise their work on the project. • Graduate students can work on multiple projects, in which case they will have a (potentially different) supervisor for each one • Departments have a department number, a department name, and a main office. • Departments have a professor (known as the chair) who runs the department. • Professors work in one or more departments, and for each department that they work in, a time percentage is associated with their job. a) (20 pts) Design and draw an ER diagram that captures the information about the university. Use only the basic ER model here; that is, entities, relationships, and attributes. Be sure to indicate any keys and participation constraints. b) (10 pts) Develop a SQL script. that creates the tables. Call this file problem3.sql. c) (10 pts) Implement the tables in your database on acadmysql.duc.auburn.edu using sufficient data of your own (i.e. add at least 5 records to each table). Provide a screenshot of a “select * from departments” query. 4. Consider the following schema/database with the following format - table_name(column1, column2, column3,..) Employee(employee-name, street, city) Works(employee-name, company-name, salary) Company(company-name, city) Manages(employee-name, manager-name) Develop SQL queries that: a) (7.5 pts) finds the names of all employees who work for Auburn Bank. b) (7.5 pts) finds the names of all employees who live in the same city as the company for which they work. c) (10 pts) finds the names, street address, and cities of residence of all employees who work for Auburn Bank and earn more than $40,000 per year.本团队核心人员组成主要包括BAT一线工程师，精通德英语！我们主要业务范围是代做编程大作业、课程设计等等。我们的方向领域：window编程 数值算法 AI人工智能 金融统计 计量分析 大数据 网络编程 WEB编程 通讯编程 游戏编程多媒体linux 外挂编程 程序API图像处理 嵌入式/单片机 数据库编程 控制台 进程与线程 网络安全 汇编语言 硬件编程 软件设计 工程标准规等。其中代写编程、代写程序、代写留学生程序作业语言或工具包括但不限于以下范围:C/C++/C#代写Java代写IT代写Python代写辅导编程作业Matlab代写Haskell代写Processing代写Linux环境搭建Rust代写Data Structure Assginment 数据结构代写MIPS代写Machine Learning 作业 代写Oracle/SQL/PostgreSQL/Pig 数据库代写/代做/辅导Web开发、网站开发、网站作业ASP.NET网站开发Finance Insurace Statistics统计、回归、迭代Prolog代写Computer Computational method代做因为专业，所以值得信赖。如有需要，请加QQ：99515681 或邮箱：[email protected] 微信：codehelp QQ：99515681 或邮箱：[email protected] 微信：codehelp
