DAD 220 Final Project Guidelines and Rubric Overview The final project for this course is to understand an existing database, write queries against it, and eventually alter its design and data. This will provide you with real-world practice for something that you will be asked to do countless times as a developer. This assessment will assess your mastery with respect to the following course outcomes: • Ensure the integrity and functionality of programs by identifying and correcting syntax errors in SQL statements • Apply proper SQL syntax in the retrieval, sorting, and restriction of data • Develop meaningful information by combining data from multiple sources using SQL syntax and logical data manipulation and management methods • Perform accurate calculations by aggregating data and applying SQL summary functions • Assess the functionality of embedded SQL, functional calls, and stored procedures within various scenarios • Articulate the fundamental concepts of SQL application within data analytics to a variety of audiences Prompt When Bill James began writing books on advanced baseball statistics in the late 1970s, nobody realized what a profound effect it would have on the game of baseball in the future. After the Oakland Athletics employed their “Moneyball” strategy in the late 1990s based on James’s advanced sabermetrics, analyzing player statistics would become commonplace across all professional teams. You have been hired to intern for a professional baseball organization. You will need to quickly come up to speed with their existing database, generate the code to recreate it in another location, run reports for upper management, and eventually alter it to store additional data. As you start working on the database, you will find that there is not a backup being stored anymore. This would be extremely problematic if the database were to crash, and there is an immediate need to create the database in another location and populate it with the existing data. This would be an easy job if there were documentation from the original database creator, but alas, there is not. Once the housekeeping is done, the executives will start requesting data to help them assess players and evaluate trades. You will need to give them easy-to-read reports that will keep their team competitive, which will in turn keep the money rolling in. Meanwhile, the season is going on, and more data is flowing in, so we will need to insert it into the appropriate tables and provide reports across both existing and new data—the life of the statistician is never easy! And along with new data comes new types of data—as new ideas are thought up, those executives will want reports on that data, whether it exists or not. And at the end of the day, you will find that some reports will be ideal to run frequently—as the data changes, they will want daily snapshots of it. So you will develop stored procedures to run the reports for them, producing output that can one day be added to programs they could access from their smartphones. Guidelines for Submission For the final project submission, create a document that describes your role as the intern. The document should be the collection (and necessary analysis and/or revisions) of Milestones One through Seven. The document will need to include the following pieces: I. Introduction a) Describe the issue you will address and the strategy for accomplishing the task. b) Using an entity relationship diagram (ERD), identify the data and links (keys) for all the tables in the final version of the sbl database in your personal profile. II. Tables a) Include the following tables with appropriate annotated SQL syntax: i. From Milestone Four: 1. Provide the teamnum and playernum for all players with a battingavg over 0.25 2. Provide the teamnum for all teams that use Acme bats 3. Provide the name and age of each player, sorted in ascending order by age 4. Provide the name of the manager and coach associated with each team, sorted ascending by the team number (one row per team) ii. From Milestone Five: 1. Provide the name, age, and team name (not team number) for each player, sorted ascending by the team name and then by age 2. Provide the team name, player name, and player batting average for all players whose batting average is above 0.230, sorted by batting average ascending 3. Provide the name of the coach, current team name, and total number of years of experience each coach has (which will be the sum of all the years of experience the coach has in all of his positions) 4. Provide the name of the manager and coach associated with each team, sorted ascending by the team name 5. Provide the team name, name of all players or coaches or managers, and the person’s role (player, manager, or coach) for all of the teams, sorting ascending by team name 6. Provide the number of each player on each team, the name of the player, the team name, and the number of years the player has been playing, sorted by player number iii. From Milestone Six: Provide an output of each player name, team, and bat manufacturer. Make sure the team number in the BATS table and AFFILIATION table correspond to each other in this query. III. Final Submission a) Validate the results b) Assess how the output addresses the needs c) Consider alternatives d) Cite sources Technical Specification Prompt Specifically, the following critical elements must be addressed: I. Introduction: a) Purpose: What is the issue that you intend to address, and how is it important to the given scenario? What data do you have available to you? (i.e., which keys will link the tables, ERD) b) Task Strategy: Outline the steps you will take to accomplish your task. II. Annotated SQL Syntax Code: a) For each table required, create appropriate SQL syntax to manipulate the table and make calculations necessary to the task at hand. This should include pre-processing restrictions (WHERE clause), aggregations (GROUP BY clause), and post-processing restrictions (HAVING clause). Note that some tables might be used as-is. b) For each table required, create SQL syntax for linking the tables using an appropriate type of join. c) Using the syntax developed in your SQL strategy, load the process onto the available platform. Test the process and perform any necessary debugging to resolve syntax errors. d) If applicable to the platform, embed the final SQL code into the broader (non-SQL) programming environment (e.g., SQL code might be embedded in a web interface and called by another language such as C# or PHP). If embedding is not deemed appropriate, provide a full explanation. e) Stored Procedures: Determine possible stored procedures from identified commonalities. Develop these stored procedures, using “CREATE PROCEDURE,” and insert the calls to these procedures into the existing SQL process. f) Thoroughly annotate the SQL code with comments to assist future users in understanding the steps/logic you followed. III. Results and Alterations: a) Output Validation: Do the results make sense (have “face validity”)? Are there independent methods you could employ to check their accuracy? b) Assess the results/output of the SQL program you have written. How well do the output reports/tables address the needs of the task? c) Consider alternative uses for your developed procedure. i. Discuss what minor alteration would be necessary in order to adapt your procedure to other issues. ii. Discuss what generalizations of procedure would be necessary to adapt your code to meet the basic needs of a variety of applications. d) Resources: Cite the resources you utilized in developing your code and specification document.
