Assignment Contentrunning Reports On Existing Data And Updating Data R
Assignment Content running reports on existing data and updating data records are very common tasks in the industry. For this assignment, you will begin with a database containing several pre-populated tables. Download and unzip the Microsoft® Access® database (ZIP file) available on the Cengage's website. You may need to convert the database depending on the version of Microsoft® Access® you are using. To convert the database, follow Microsoft®'s Convert a Database to the .accdb File Format instructions. Open the database in Microsoft® Access® and explore the tables it contains by following this path: /folderYouNameWhenYouUnzip/_526407/Student/Ch07-Intro-to-SQL/Databases/ Ch07_SaleCo.mdb. If you have chosen not to use Microsoft® Access® in this course, you will need to download the SQL statements for MySQL, Oracle®, or SQLServer and run those statements against your RDBMS to create a populated database. Download the Select and Update Data in Related Tables document and follow the instructions. Your completed assignment will consist of one document and two screenshots placed in one document (one screenshot showing the results of the "before" SELECT statement and a second showing the results of the "after" SELECT statement).
Paper For Above instruction
This assignment involves executing data retrieval and update operations within a relational database, emphasizing practical skills necessary for industry tasks such as report generation and data maintenance. The process begins with the use of a pre-populated database in Microsoft Access, with a consideration for conversion if necessary, or adaptation for other SQL-based systems like MySQL, Oracle, or SQL Server.
Understanding the database structure is fundamental. The provided database contains multiple tables related to a business scenario, likely involving sales or customer data, given the filename 'Ch07_SaleCo.mdb'. The initial step involves exploring these tables to comprehend the schema, relationships, and data content. Using Microsoft Access or an equivalent RDBMS, queries are run to retrieve specific data for reporting purposes before any data modifications.
The core of the task is to execute select statements to generate reports based on existing data. These reports should demonstrate the current state of the data prior to any updates. Taking a screenshot of the SELECT query results provides a visual record of this initial state, essential for comparison and validation.
Subsequently, updates are applied to the data. These may involve modifying records to reflect changes, correct errors, or update statuses according to instructions provided in the accompanying document. After executing the update statements—commonly achieved through SQL UPDATE commands—a second SELECT query is run to verify and visualize the updated data.
The comparison of the before and after screenshots illustrates the impact of the data modifications. Including these images within a single report document creates a clear audit trail of the changes made and the data state before and after the updates.
In summary, the key academic competencies demonstrated in this assignment include database exploration, writing and executing select and update SQL statements, managing data states, and documenting results with visual evidence. These skills are directly applicable in real-world data management tasks where ongoing reporting and data accuracy are essential for operational success.
Finalizing the assignment involves compiling the queries, their output screenshots, and any notes or observations into a cohesive document. This exercise emphasizes the importance of transparent data handling and reinforces best practices for SQL reporting and data updating procedures within relational databases.
