Database Design and Creation数据库北美project解析数据库编程

Database Design and Creation Your answer should be structured according to the guidance below – failure to do this will result in lost marks – you should include a clear table of contents showing the page number for each of the required sections Part A –Database Creation For this part of the assignment: a. Take the conceptual database diagram you created for the previous 
assignment and transform. it into a logical model, presenting this model as a second UML diagram1. 
b. Once you have the logical model, you should then write SQL scripts to create your tables and add the required constraints. The SQL scripts should be created MANUALLY and submitted as part of the assignment, and you must use the PostGIS database provided for this work. 
c. Once you have created the tables, populate each table with a minimum of THREE rows of data (you MUST use SQL to do this manually – you are not permitted to import the data from other sources). The data should be sufficient to allow you to test out the SQL for your listed functional requirements. 
d. Create and test the SQL statements for each of your functional requirements. 
 You are required to hand in a report showing2: 1. Your conceptual UML diagram from Assignment 1 (make sure to copy the 
diagram exactly as you submitted it). 
2. The logical UML diagram derived from the conceptual diagram. Make sure this diagram is derived directly from the conceptual diagram you presented. 
3. The SQL scripts you used to create and populate the tables (the tables and data should also be created inside your PostgreSQL work area) 
1 NB: Do not introduce any new entities or fields into the logical diagram, apart from those specifically required by the translation process.
2 Note – there is no need to write any text to explain the different elements this report – just be sure that you stick EXACTLY to what is asked for. BE SURE TO CLEARLY STATE YOUR USER NUMBER IN YOUR ASSIGNMENT SO THAT I CAN TEST YOUR QUERIES For each table, you should include the entity on which it is based alongside the SQL script. that you used to create the table and any constraints. This should be done in a table as follows: 4. The SQL showing the INSERT statements for each table, presented as a table as shown here: 
5. A map (created in QGIS) of any spatial data you have as part of this exercise. 
6. A 3D screen shot (from FME) of your 3D data, with appropriate background mapping. 
7. A table showing the list of Functional Requirements from Assignment 1 (unchanged) and the SQL you used to answer each requirement, structured as follows: 
Entity Name CREATE TABLE SCRIPT. PRIMARY KEY CONSTRAINT FOREIGN KEY CONSTRAINTS UNIQUE CONSTRAINTS (From the logical diagram) SQL SQL SQL SQL TABLE NAME SQL INSERT STATEMENTS Require- ment # Requirement Description List of T able(s) Involved SPATIAL JOIN SQL QUERY Screenshot of results from PG Admin NB: The text here should be identical to that in Assignment 1 These should correspond to the entities listed in Assignment 1 Yes/No (identical to Assignment 1) Yes/No (Identical to Assignment 1) The SQL Query required to answer the requirement If the SQL failed insert the error message. If you were unable to meet the requirement, leave blank. TOTALS Remember that 3 join queries and 5 spatial queries are required. NB: All SQL should be included in the report, but also uploaded as a separate single text file so that the database creation process can be re-run from scratch. For Part A you will be assessed on your ability to create a database using all the principles we covered in class over the course of this module and on how well that database fits your original specification from Part 1 and answers the functional requirements you set out.
