SQL代写创建数据表 Creating a Database in SQL帮做数据库编程

SQL代写创建数据表 Creating a Database in SQL帮做数据库编程作业& Getting startedThis assignment involves using SQL to create and populate database tables. It is based on Chapter 6 of the MDM textbook. Review in-class handouts and exercises. Please make sure to complete all of the required reading and review in-class practice.Problem descriptionThe ERD on the next page presents a conceptual database model for the following scenario:A local conservatory would like to maintain a record of auditions, in which juries select applicants for participating in different conservatory ensembles. Each jury is qualified to judge auditions for one or more instruments. Each applicant is assigned an audition for their chosen instrument at a given date, time and location. A jury, upon listening to an applicant during the audition, records an audition score (between 1 and 10) and a recommendation regarding the placement of the applicant.Compose the SQL code (i.e., CREATE statements) to create the table structures based on the above scenario and ERD on the next page. Replace all composite keys with surrogate ones.Use the following constraints, where appropriate:primary key,foreign keys and referential integrity constraints,uniqueness constraints on all non-PK candidate keys,value check constraints (constraints on time and date attributes are for extra credit only)default values.Write SQL commands to populate the database with3 different juries5 different instruments (some, without an associated jury)8 applicants6 auditionsWrite SQL code to drop a Foreign Key constraint you created in question 1 and to add it back.Write the SQL code to modify the length of one of the attributes you created in question 1Use an SQL Update command to modify all names of instruments to uppercase letters.To illustrate the constraints, for each of the four tables, include an INSERT statement that violates one constraint associated with the table, but is correct in all other respects. In a comment, explain which constraint is violated by this INSERT.Submission and gradingSubmit a. the code you composed for parts 1-6 above, and b. a listing of all data in the tables (obtained via SELECT *) as a single file (with extension.sql) via Blackboard prior to the deadline.All code (except for the code for part 6) should be executable and should not produce any errors when executed. Execution errors in the code will result in the score of 0 for each failed statement.Those solutions that were not submitted in time electronically will be considered late and will incur 50% late penalty (see course policies). Hand in a printed version in class. Not handing in a printer version will result in a reduced grade and possibly a delay in grading.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
