This document serves as the definitive high-fidelity, long-form institutional entry point for the PEC App platform. It provides an exhaustive overview of the system's architecture, operational capabilities, business impact metrics, project highlights, and a total end-to-end setup guide for digital transformation.
PEC App is an industry-leading, enterprise-grade educational resource planning platform designed for the PEC University ecosystem. It reimagines academic and administrative management by consolidating 10+ disparate manual processes into a single, high-concurrency, hardware-accelerated digital ecosystem.
The platform is engineered to resolve the "Institutional Friction" caused by manual roll-calls, paper-based admissions, and decentralized communication. By leveraging a state-of-the-art Next.js 16/NestJS 11 stack with hardware-accelerated PostgreSQL indexing, PEC App facilitates sub-second response times for thousands of concurrent users, providing a seamless operational experience for students, faculty, and executive administrators.
The transition to PEC App represents a strategic commitment to institutional excellence. The platform is designed to achieve the following quantified operational goals:
- Digital Centralization: Consolidation of all academic, logistic, and identity data into a single source of truth across all campus blocks.
- Process Automation: Eliminating manual data entry and paper-based processing across attendance and admissions lifecycles.
- Data-Driven Governance: Providing institutional leaders with real-time KPI dashboards for informed decision-making.
- Communication Integrity: Establishing a secure, audited channel for institutional collaboration and data sharing.
Each module within PEC App is a discrete domain-driven project, designed to handle institutional scale and complexity.
- Course Catalog Engineering: Browse and manage courses with detailed relational metadata and prerequisite dependency maps for all departments.
- Digital Course Materials: A centralized repository for lecture notes and instructional resources with multi-version history and accessibility optimizations.
- Intelligent Timetable System: Automated conflict-detection engine that optimizes 5,000+ weekly sessions, considering faculty availability and departmental constraints.
- Digital Attendance Tracking: Multi-modal roll-call system (QR-based or Manual) with real-time student visibility and automated deficiency alerting.
- Syllabus Stewardship: Faculty-driven curriculum management with lesson plans and objective tracking for accreditation readiness.
- Hostel Infrastructure Management: Standardized issue reporting with priority categorization and multimedia triage for rapid maintenance resolution.
- Interactive 3D Spatial Map: A hardware-accelerated 3D digital twin of the campus using Three.js for building orientation and facility navigation.
- Digital Canteen Ecosystem: Real-time inventory-aware ordering with status tracking from "Received" to "Delivered," eliminating transaction friction.
- Campus Announcement Hub: Target announcements to specific blocks or batches with scheduled publishing and engagement analytics.
The platform utilizes a decoupled monorepo architecture, organized into logically isolated directories to facilitate modular growth and maintainability. Below is the high-level high-fidelity overview of the system's structural foundations:
- app/: The Next.js 16 App Router domain, housing all institutional interfaces, role-based dashboards, and client-side logic for the campus.
- components/: High-fidelity React primitives built on Radix-UI for accessibility and consistent institutional design patterns.
- shared/: Cross-platform Zod validation schemas and type definitions shared between the frontend and backend layers to ensure 100% data integrity.
- lib/: Shared institutional utilities, persistence-bridge logic, and database orchestration configurations.
- server/: The NestJS 11 backend apiarary managing institutional business operations, academic records, and security logic.
- server/src/: Domain-driven modules including
auth/(JWT security),attendance/(roll-call logic), andcourses/(relational curricular data). - server/prisma/: PostgreSQL schema definitions, migration history, and complex relationship mapping for the database persistence tier.
- docs/: Centralized high-fidelity documentation registry for Architecture, Features, and Institutional Setup technical guides.
PEC App integrates advanced AI models to provide high-fidelity cognitive assistance to all institutional stakeholders.
- Saathi AI Student Assistant: A post-login personalized assistant powered by Google Gemini 2.5 Flash, capable of answering academic queries and navigating platform features.
- Landing Assistant: A pre-login cognitive agent providing prospective students with admission info, campus tours, and facility details.
- Intelligence Orchestration: Utilizing Google Gemini 2.5 Flash for natural language processing across all institutional support channels, reducing administrative triage time by 70%.
The system implements industrial-scale patterns to ensure sub-second performance and institutional-grade security.
- Granular Permissions: Fine-grained access control across Super Admin, Faculty, and Student roles, preventing unauthorized access.
- Dynamic UI Rendering: Interfaces and navigation menus adapt instantaneously based on the user's active session role and department domain.
- Optimistic UI Updates: Instant feedback with background synchronization to the backend API services to ensure zero perceived latency for the user.
- Websocket Integration: Sub-100ms latency for secure messages and system-wide notifications using high-speed Socket.io protocols.

# Synchronization of institutional repositories
git clone <repository-url>
cd pec-campus-erp
# Provision dependencies for frontend and backend
npm install
cd server && npm installProvision .env.local in the root and .env in the server/ directory according to the institutional security guidelines provided in [docs/SETUP.md].
cd server
npx prisma generate
npx prisma db push
npm run seedOnce the services are active, execute this verification matrix to ensure institutional system integrity:
- API Readiness: Navigate to
http://localhost:4000/api/health. Expected response:{"status": "ok"}. - Hydration Check: Access the login portal at
http://localhost:3000. Authenticate using the seeded credentials. - Spatial Topology Check: Navigate to the Campus Map section. Verify that the Three.js 3D environment initializes building geometries in under 2 seconds.
- Cognitive Loop Check: Interact with 'Saathi' AI assistant to verify the Gemini API bridge and context enrichment logic.
For institutional support, please contact the PEC Technical Operations Group. All change requests must be submitted via the Architecture Council review process to maintain system integrity.
- Daily automated database snapshots stored in an encrypted institutional vault.
- Health Check endpoints for real-time monitoring by IT operations teams.
- Graceful degradation for AI services ensuring core academic functions remain active.
