Populate Your Database And Write SQL Queries For Data Manipu

Question

I have the database done from the previous module Ill send to you upon me accepting. In the last module, you build your database. But a database without any data isn’t useful at all! In the last module, you build your database. But a database without any data isn’t useful at all! So now that you have had some practice in writing SQL queries and you have a functional database in at least third normal form (from the previous module), it’s time to populate your database and write some queries! Step I Populate your database that you created in module 5 with some representative testing data. Include at least 15 records for each of the tables (use INSERT commands or GUI tools provided by the DBMS you select). Step II Think of descriptions for six data querying requirements that could be answered from the data stored in your database, three requirements to change data already in the database, and three requirements to delete data already in the database. Answers to your querying requirements should contain at least two JOINs; two aggregation functions; a GROUP BY clause; and three WHERE or HAVING clauses. See the discussion instructions for examples. Step III In a Word document, prepare the following for each DML requirement you came up during Step II: The description for your requirement The DML statement (SQL command) that will get you the data you need – do not use a query generator or graphical tool to write this; write it on your own A screenshot of the resulting query output when executed on your database Populate your database and write SQL queries for data manipulation and retrieval I have the database done from the previous module Ill send to you upon me accepting.

The following paper demonstrates how to populate a previously established database with testing data, and craft SQL queries to retrieve, modify, and delete data according to specified requirements. This process validates the database’s functionality and prepares it for practical data analysis and management tasks. Introduction Effective database management relies heavily on the ability to insert, update, and delete data precisely within a structured system. After designing and normalizing the database in the previous module, the next critical step involves populating it with meaningful sample data and creating robust queries to extract insights. These activities not only test the integrity and relational capabilities of the database but also lay the groundwork for real-world data operations. Populating the Database Populating the database entails inserting at least 15 records into each table using SQL INSERT statements or GUI tools provided by the chosen DBMS. This dataset should be representative and sufficient to enable meaningful queries. For example, a typical database might include tables such as Customers, Orders, Products, Suppliers, Employees, and Shipments, each requiring diverse and realistic data entries. Properly populating these tables ensures that subsequent queries can accurately analyze relationships, perform aggregations, and demonstrate complex SQL functionality. Designing Data Querying Requirements Following data population, the next phase involves conceptualizing six querying requirements that leverage advanced SQL features: At least two JOIN operations to retrieve related data across tables Two aggregation functions, such as COUNT, SUM, AVG, MAX, or MIN A GROUP BY clause to organize data for summarization Three WHERE or HAVING clauses to filter or conditionally display data Additionally, three requirements should involve updating data (via UPDATE statements) and three for deleting data (using DELETE statements), further testing data manipulation
