Hey there! Let's break down the best UI approaches for your teacher-focused exam data tool, paired with your SQL backend. Based on your needs—multi-teacher access, handling dense student data (30+ students × 40+ data points per exam), and pre-built reports—here are my top recommendations tailored to educators who need efficiency and simplicity:

If you want to get up and running without diving into full-stack development, these tools are perfect:

• Microsoft Power Apps
  Connects directly to SQL Server (or Azure SQL) out of the box. It includes built-in user authentication (supporting multi-teacher logins) and role-based access control—so you can restrict each teacher to only their own exam data. For bulk entry, use the data table control (like a spreadsheet) to input 30+ students’ 40+ data points at once. Pre-built reports can be created with embedded Power BI visualizations, or you can generate quick summaries using Power Apps’ native reporting features.
• Google Apps Script + Google Sheets
  Ideal if you’re already comfortable with the Google ecosystem. Link a Google Sheet to your Cloud SQL database using Apps Script, then use the sheet as your UI for data entry. Multi-teacher access is handled via Google Accounts, and you can set permissions so teachers only edit their own tabs. For reports, leverage Sheets’ pivot tables, charts, or tie in Google Data Studio for more polished dashboards. Bonus: Teachers can upload pre-filled Excel/CSV files directly to the sheet for bulk imports.
• Retool
  Built specifically for internal tools, Retool lets you drag-and-drop UI components (tables, forms, charts) and connect them to your SQL database in minutes. It has a ready-made user management system for multi-teacher logins, and its bulk edit table makes entering 30×40 datasets a breeze. Pre-built reports can be configured by linking SQL queries to visualizations (bar charts, score distributions) with zero frontend code.

If you want more flexibility to tailor the UI exactly to your workflow, these frameworks strike a balance between customization and ease of use:

• Django (Python)
  Django’s built-in authentication system makes implementing multi-teacher logins and role-based access trivial. Use Django Admin to generate a quick data entry interface, or build custom forms with WTForms for a more tailored experience. For bulk data entry, add a CSV upload feature—write a simple view to validate the file and import rows into your SQL tables. Pre-built reports can be rendered using Django templates to display summary tables, or integrate Plotly/Matplotlib for interactive charts.
• Flask (Python)
  A lighter alternative to Django. Use Flask-Login for user authentication and SQLAlchemy to connect to your SQL database. Build a basic UI with Jinja2 templates, and add a bulk entry form or CSV upload handler. For reports, pull aggregated data from SQL queries and render it with Chart.js for client-side visualizations. Great if you want a minimal, focused tool without Django’s extra features.
• Node.js + Express
  Use Express to build a simple backend, Passport.js for multi-user authentication, and EJS/Handlebars for server-rendered UI pages. Implement bulk entry via a spreadsheet-style table or CSV upload, and fetch data from your SQL database to populate pre-built reports with Chart.js or D3.js. Good if you’re more comfortable with JavaScript.

No matter which approach you choose, make sure these features are front and center:

• Role-Based Access Control (RBAC)
  In your SQL schema, add a teacher_id foreign key to your exams and student_scores tables. On the UI side, filter all data so teachers only see/edit their own exams—never others’ data.
• Bulk-First Data Entry
  Avoid forcing teachers to input each student’s 40+ data points one by one. Either:
  • Use a spreadsheet-style editable table (inline editing for all rows/columns)
  • Support CSV/Excel template uploads (provide a pre-formatted template teachers can fill out and import)
• Pre-Built Report Dashboards
  Focus on the reports teachers actually need:
  • Single exam summary: Average scores, highest/lowest scores, score distribution per data point (e.g., topic mastery)
  • Student performance trends: Compare scores across multiple exams for individual students
  • Export options: Let teachers download reports as PDF or Excel for grading or parent meetings
• Simple, Intuitive Navigation
  Keep the menu minimal: My Exams → Enter Scores → View Reports → Settings. Teachers don’t need fancy bells and whistles—they need to get tasks done quickly.

To make your UI work smoothly with SQL, structure your tables like this (example):

-- Teachers table for login/access control
CREATE TABLE teachers (
    teacher_id INT PRIMARY KEY AUTO_INCREMENT,
    username VARCHAR(50) UNIQUE NOT NULL,
    password_hash VARCHAR(255) NOT NULL,
    email VARCHAR(100) UNIQUE NOT NULL
);

-- Exams table tied to a teacher
CREATE TABLE exams (
    exam_id INT PRIMARY KEY AUTO_INCREMENT,
    teacher_id INT NOT NULL,
    exam_name VARCHAR(100) NOT NULL,
    exam_date DATE NOT NULL,
    FOREIGN KEY (teacher_id) REFERENCES teachers(teacher_id)
);

-- Student scores table (40+ data points can be columns here, or use a normalized table if metrics are dynamic)
CREATE TABLE student_scores (
    score_id INT PRIMARY KEY AUTO_INCREMENT,
    exam_id INT NOT NULL,
    student_name VARCHAR(100) NOT NULL,
    metric_1 DECIMAL(5,2),
    metric_2 DECIMAL(5,2),
    -- ... add 38+ more metric columns as needed
    FOREIGN KEY (exam_id) REFERENCES exams(exam_id)
);

If your 40+ data points are dynamic (e.g., different exams have different metrics), use a normalized schema instead:

CREATE TABLE score_metrics (
    metric_id INT PRIMARY KEY AUTO_INCREMENT,
    metric_name VARCHAR(50) NOT NULL
);

CREATE TABLE student_scores_normalized (
    score_id INT PRIMARY KEY AUTO_INCREMENT,
    exam_id INT NOT NULL,
    student_name VARCHAR(100) NOT NULL,
    metric_id INT NOT NULL,
    score DECIMAL(5,2) NOT NULL,
    FOREIGN KEY (exam_id) REFERENCES exams(exam_id),
    FOREIGN KEY (metric_id) REFERENCES score_metrics(metric_id)
);
