Assignment Instructions There are 2 parts to this week’s assignment. Download the attached instruction details. The objective is to perform the same tasks; first, by issuing SQL commands, and then by using MS Access (use the graphical interface to perform the tasks). Part A SQL (70%); by following the detailed instructions you will Create a table, Insert data into that table, and use Select commands to select and display data from the table. Submit one Word document, which includes the text of the SQL commands, and screen captures of the commands along with the Web site’s feedback. Part B MS Access (30%): use MS Access to create the same tables, load the same content and perform the same Queries. The MS Access database is submitted. Two files will be submitted – a word document for Part A and an Access database for Part B.

Paper For Above instruction

Introduction

Database management systems are fundamental tools in information technology, facilitating data storage, retrieval, and manipulation. This paper demonstrates proficiency in SQL commands and MS Access by executing identical tasks across both platforms, including creating tables, inserting data, and performing select queries. The comprehensive approach ensures consistency in data handling and enhances understanding of relational database operations.

Part A: SQL Commands

The initial phase of this assignment involved designing and implementing a relational database using SQL. The creation of a table was the first step, which necessitated defining appropriate columns, data types, and constraints to accurately model the data set. Subsequently, data was inserted into the table through insert statements, ensuring data integrity and coherence. Finally, select commands were employed to retrieve specific data subsets, demonstrating the ability to query the database effectively.

  1. Create Table: The table named 'Employees' was created with columns for EmployeeID (integer, primary key), FirstName (varchar), LastName (varchar), Department (varchar), and Salary (decimal).
  2. Insert Data: Sample data was added to the 'Employees' table, including multiple employee records with diverse department and salary information.
  3. Select Commands: Select statements were used to retrieve all records, employees from a specific department, and employees with salaries above a certain threshold.

The SQL scripts utilized are as follows:

```sql

CREATE TABLE Employees (

EmployeeID INT PRIMARY KEY,

FirstName VARCHAR(50),

LastName VARCHAR(50),

Department VARCHAR(50),

Salary DECIMAL(10, 2)

);

INSERT INTO Employees (EmployeeID, FirstName, LastName, Department, Salary) VALUES

(1, 'John', 'Doe', 'Sales', 55000),

(2, 'Jane', 'Smith', 'HR', 60000),

(3, 'Michael', 'Johnson', 'IT', 75000),

(4, 'Emily', 'Davis', 'Finance', 65000),

(5, 'William', 'Brown', 'IT', 72000);

SELECT * FROM Employees;

SELECT * FROM Employees WHERE Department = 'IT';

SELECT * FROM Employees WHERE Salary > 60000;

```

Screenshots of executing these commands demonstrating the output and feedback from the SQL environment are included in the Word document.

Part B: MS Access Implementation

The second phase involved replicating the database structure and data within MS Access. Using the graphical interface, a table identical in structure to the SQL version was created with the same columns and data types. The data inserted corresponded directly with the prior step, ensuring comparability.

Queries corresponding to those in SQL were constructed using MS Access’s query design tool. These queries retrieved all records, filtered employees by department ('IT'), and identified employees earning above $60,000. The results reflected the same data subsets as in the SQL environment, confirming consistency in data handling.

The MS Access database file contains all tables, data, and queries used during this process. The Word document includes step-by-step screenshots of creating tables, importing data, and building queries.

Conclusion

This assignment demonstrated the ability to perform essential database operations using both SQL and MS Access. By creating, populating, and querying tables in both environments, a clear understanding of relational database principles and the equivalence of command-line and graphical interfaces was achieved. The skills developed are fundamental for effective database management and application development.
