For an instructor lead, in-depth look at learning SQL click below.
In this blog post, we will learn how to design and implement a Project Task Assignment and Progress Tracking System using Structured Query Language (SQL) as our primary tool. With SQL, you can manage data held in a relational database management system, making it perfect for handling tasks and project metrics. Here is a simplified way of achieving this.
Database Tables Creation
The first step is to create the database tables that will hold our project data. These will roughly include a Projects Table, a Tasks Table, a Users Table, and a Task_Assignment Table to relate tasks to users.
|
1 2 3 4 5 6 7 8 9 |
CREATE TABLE Projects( Id int primary key, Name varchar(255), Description text, StartDate datetime, EndDate datetime ); |
|
1 2 3 4 5 6 7 |
CREATE TABLE Users ( Id int primary key, Name varchar(255), Email varchar(255) ); |
|
1 2 3 4 5 6 7 8 9 10 11 |
CREATE TABLE Tasks ( Id int primary key, Name varchar(255), ProjectId int REFERENCES Projects(Id), Description text, StartDate datetime, EndDate datetime, Status varchar(50) ); |
|
1 2 3 4 5 6 7 |
CREATE TABLE Task_Assignment ( Id int primary key, UserId int REFERENCES Users(Id), TaskId int REFERENCES Tasks(Id) ); |
Data Insertion
Next, we need to insert some hypothetical data into our tables.
|
1 2 3 4 |
INSERT INTO Projects (Id, Name, Description, StartDate, EndDate) VALUES (1, 'Project Alpha', 'This is Project Alpha.', '2022-01-01','2022-12-31'); |
|
1 2 3 4 |
INSERT INTO Users (Id, Name, Email) VALUES (1, 'John Doe', <a href="mailto:'johndoe@example.com'" >'johndoe@example.com'</a>); |
Data Manipulation
With the data in place, you can manipulate it to reflect task assignment and track progress.
|
1 2 3 4 |
INSERT INTO Tasks (Id, Name, ProjectId, Description, StartDate, EndDate, Status) VALUES (1, 'Task 1', 1, 'This is the first task for Project Alpha.', '2022-01-15', '2022-02-15', 'Not Started'); |
|
1 2 3 4 |
INSERT INTO Task_Assignment (Id, UserId, TaskId) VALUES (1, 1, 1); |
Data Retrieval
Finally, we can retrieve this data, showing which user is assigned to which task in which project, as well as the task’s status.
|
1 2 3 4 5 6 7 |
SELECT U.Name as UserName, P.Name as ProjectName, T.Name as TaskName, T.Status as TaskStatus FROM Task_Assignment TA JOIN Users U on U.Id = TA.UserId JOIN Tasks T on T.Id = TA.TaskId JOIN Projects P on P.Id = T.ProjectId; |
This simple system can be expanded and modified to suit a variety of project-tracking needs. With SQL, the possibilities for data management and tracking are extensive. I hope this blog post provides a starting point for your project-tracking endeavors.
