BlogPlatformDB is a SQL-based database designed for a blogging platform. This database supports various features such as managing blog posts, users, comments, categories, tags, and payment-related information. It also includes stored procedures, functions, and triggers to enforce business logic and ensure data integrity.
- Blog Post Management : Stores and organizes blog posts, including title, content, category, creation, and update timestamps.
- User and Role Management : Users can register, create profiles, and be assigned roles such as User or VIP.
- Comments and Likes : Users can comment on and like blog posts, fostering interaction.
- Stored Procedures and Functions : Complex business logic like upgrading a user to VIP, adding comments, and generating notifications is handled through stored procedures and functions.
- Triggers : Logs changes to blog posts and manages soft deletes.
The database consists of 17 tables that form the core functionality of the blogging platform. Below is a visual representation of the database schema:
- UserAccount : Stores essential user data for authentication and role assignment.
- UserProfile : Contains optional profile data like first name, last name, biography, and profile picture.
- BlogPosts : Holds the blog content created by authors.
- Comments : Stores comments on blog posts.
- Likes : Tracks the likes each blog post receives.
- Payment : Stores payment information for users upgrading to VIP status.
- PostUpdateLog: Logs changes to blog posts for historical tracking.
- Clone the Repository:
git clone https://github.com/mahboube89/BlogPlatformDB.git
- Import SQL Scripts:
- Open SQL Server Management Studio (SSMS).
- Import the SQL scripts from the SqlScripts/ folder into your database instance.
- Ensure that all tables, procedures, functions, and triggers are correctly created.
The repository includes SQL scripts for all database objects, including tables, views, stored procedures, functions, and triggers. These scripts are located in the sql/ folder.
- SF_Get_Like_Count_By_Post : Returns the number of likes for a specific blog post. Useful for assessing the popularity of a post.
- SF_Get_Post_Count_By_Category: Returns the number of blog posts in a specific category.
- TF_Get_Most_Like_Post_By_Category: Returns the blog post with the most likes in a specific category. This function helps identify the most successful posts within a category.
- TF_Get_Posts_By_Author: Returns a table with all blog posts by a specific author.
- TF_Get_Tags_By_Post : Returns all tags associated with a specific blog post.
- SP_Add_Comment : Allows a user to add a comment to a blog post after verifying that the user has read the post. It also ensures that the comment text is not empty and does not exceed the maximum length.
- SP_Upgrade_User_To_VIP: Upgrades a user's account to VIP status after a successful payment. It updates the user's VIP details and logs the payment in the database.
- SP_Create_Post_Notifications: Generates notifications for users when a new blog post is created. This is used to inform subscribers about new content.
- TR_BlogPosts_Delete_Log: This trigger performs a soft delete of a blog post by setting the is_deleted flag to 1 instead of removing it from the database entirely. It also logs the deletion in the PostUpdateLog table, capturing who deleted the post and when.
- TR_BlogPosts_Insert_Log: Logs the creation of a new blog post in the PostUpdateLog table.
- TR_BlogPosts_Update_Log: Logs updates to blog posts, including changes to post_title, post_content, is_premium, and category_id. It also updates the update_at timestamp in the BlogPosts table.
There are several potential extensions for this project that could add new features and flexibility:
- Archiving Old Blog Posts: Implement a system to archive old blog posts, moving them from the main table to an archive table.
- User Follow System : Allow users to follow each other and receive notifications about their activities.
- Media Management : Extend support for images and videos in blog posts, perhaps integrating with a media management system.
- Sharing Blog Posts : Enable users to share blog posts on other platforms or with other users.
- Gender Information : Add a Gender table to store gender-specific information for user profiles.
