 **`void create_tables()`**
 - Creates all required database tables using SQL queries from `SQLQueries.hpp`
 - Tables created:
-  - `enrollments`: Student course enrollments
-  - `exam_results`: Individual exam scores
-  - `course_results`: Final course grades and statistics
+  - `imu_data`: IMU sensor readings with linear acceleration and angular velocity data

 ### Data Operations
 
-#### Student Course Management
+#### IMU Data Storage
 
-**`std::vector<StudentCourse> queue_pending_combinations()`**
-> Returns vector of StudentCourse objects for processing queue
+**`bool store_imu_data(double linear_accel_x, double linear_accel_y, double linear_accel_z, double angular_vel_x, double angular_vel_y, double angular_vel_z)`**
+> Returns `true` on successful storage, `false` on failure
 
-- Gets all student-course combinations that need exam results generated
-- Executes complex SQL query to find missing exam results
-
-**`bool enroll_student_into_course(const StudentCourse& sc)`**
-> Returns `true` on successful enrollment, `false` on failure
-
-- Enrolls a student into a specific course
-
-#### Exam Result Processing
-
-**`bool store_exam_result(const std::string& student_name, const std::string& course_name, int grade)`**
-- Stores individual exam results in the database
+- Stores IMU sensor readings in the database
 - Parameters:
-  - `student_name`: Name of the student
-  - `course_name`: Name of the course
-  - `grade`: Exam score (10-100)
-
-**`bool store_final_course_result(const StudentCourse& sc, int exam_count, int final_grade)`**
-- Stores calculated final course results
-- Parameters:
-  - `sc`: StudentCourse object containing student and course names
-  - `exam_count`: Number of exams taken
-  - `final_grade`: Calculated final grade
-- Used by grade calculation nodes for final result storage
-
-#### Grade Retrieval
-
-**`int get_final_course_grade(const StudentCourse& sc)`**
-> Returns:
->  - `> 0`: Valid final grade (rounded average)
->  - `-1`: No exams taken or no results found
-
-- Gets final calculated grade for a student-course combination
-- Performs average calculation with proper rounding
-- Used by nodes to check if final grading is complete
+  - `linear_accel_x`: Linear acceleration on X-axis
+  - `linear_accel_y`: Linear acceleration on Y-axis
+  - `linear_accel_z`: Linear acceleration on Z-axis
+  - `angular_vel_x`: Angular velocity around X-axis
+  - `angular_vel_y`: Angular velocity around Y-axis
+  - `angular_vel_z`: Angular velocity around Z-axis
+- Automatically adds timestamp on insertion
