# MOPC Platform - Database Design
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
|
||
|
|
The MOPC platform uses PostgreSQL as its primary database, accessed via Prisma ORM. The schema is designed for:
|
||
|
|
|
||
|
|
1. **Type Safety**: Prisma generates TypeScript types from the schema
|
||
|
|
2. **Extensibility**: JSON fields allow future attributes without migrations
|
||
|
|
3. **Auditability**: All significant changes are logged
|
||
|
|
4. **Performance**: Strategic indexes for common query patterns
|
||
|
|
|
||
|
|

|
## Indexing Strategy
|
||
|
|
|
||
|
|
### Primary Indexes (Automatic)
|
||
|
|
- All `@id` fields have primary key indexes
|
||
|
|
- All `@unique` constraints have unique indexes
|
||
|
|
|
||
|
|
### Query-Optimized Indexes
|
||
|
|
|
||
|
|
| Table | Index | Purpose |
|
||
|
|
|-------|-------|---------|
|
||
|
|
| User | `email` | Login lookup |
|
||
|
|
| User | `role` | Filter by role |
|
||
|
|
| User | `status` | Filter active users |
|
||
|
|
| Program | `status` | List active programs |
|
||
|
|
| Round | `programId` | Get rounds for program |
|
||
|
|
| Round | `status` | Filter active rounds |
|
||
|
|
| Round | `votingStartAt, votingEndAt` | Check voting window |
|
||
|
|
| Project | `roundId` | Get projects in round |
|
||
|
|
| Project | `status` | Filter by status |
|
||
|
|
| Project | `tags` | Filter by tag (GIN index) |
|
||
|
|
| Assignment | `userId` | Get user's assignments |
|
||
|
|
| Assignment | `projectId` | Get project's reviewers |
|
||
|
|
| Assignment | `roundId` | Get all assignments for round |
|
||
|
|
| Assignment | `isCompleted` | Track progress |
|
||
|
|
| Evaluation | `status` | Filter by completion |
|
||
|
|
| Evaluation | `submittedAt` | Sort by submission time |
|
||
|
|
| AuditLog | `timestamp` | Time-based queries |
|
||
|
|
| AuditLog | `entityType, entityId` | Entity history |
|
||
|
|
|
||
|
|
### JSON Field Indexes
|
||
|
|
|
||
|
|
For PostgreSQL JSONB fields, we can add GIN indexes for complex queries:
|
||
|
|
|
||
|
|
```sql
|
||
|
|
-- Add via migration if needed
|
||
|
|
CREATE INDEX idx_project_metadata ON "Project" USING GIN ("metadataJson");
|
||
|
|
CREATE INDEX idx_evaluation_scores ON "Evaluation" USING GIN ("criterionScoresJson");
|
||
|
|
```
|
||
|
|
|
||
|
|
## Migration Strategy
|
||
|
|
|
||
|
|
### Development
|
||
|
|
```bash
|
||
|
|
# Push schema changes directly (no migration files)
|
||
|
|
npx prisma db push
|
||
|
|
|
||
|
|
# Generate client after schema changes
|
||
|
|
npx prisma generate
|
||
|
|
```
|
||
|
|
|
||
|
|
### Production
|
||
|
|
```bash
|
||
|
|
# Create migration from schema changes
|
||
|
|
npx prisma migrate dev --name description_of_change
|
||
|
|
|
||
|
|
# Apply migrations in production
|
||
|
|
npx prisma migrate deploy
|
||
|
|
```
|
||
|
|
|
||
|
|
### Migration Best Practices
|
||
|
|
1. **Never** use `db push` in production
|
||
|
|
2. **Always** backup before migrations
|
||
|
|
3. **Test** migrations on staging first
|
||
|
|
4. **Review** generated SQL before applying
|
||
|
|
5. **Keep** migrations small and focused
|
||

## Data Seeding
|
||
|
|
|
||
|
|
```typescript

## Query Patterns
|
||
|
|
|
||
|
|
### Get Jury's Assigned Projects
|
||
|
|
```typescript
|
||
|
|
const assignments = await prisma.assignment.findMany({
|
||
|
|
where: {
|
||
|
|
userId: currentUser.id,
|
||
|
|
round: {
|
||
|
|
status: 'ACTIVE',
|
||
|
|
},
|
||
|
|
},
|
||
|
|
include: {
|
||
|
|
project: {
|
||
|
|
include: {
|
||
|
|
files: true,
|
||
|
|
},
|
||
|
|
},
|
||
|
|
evaluation: true,
|
||
|
|
},
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
### Get Project Evaluation Stats
|
||
|
|
```typescript
|
||
|
|
const stats = await prisma.evaluation.groupBy({
|
||
|
|
by: ['status'],
|
||
|
|
where: {
|
||
|
|
assignment: {
|
||
|
|
projectId: projectId,
|
||
|
|
},
|
||
|
|
},
|
||
|
|
_count: true,
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
### Check Voting Window
|
||
|
|
```typescript
|
||
|
|
const isVotingOpen = await prisma.round.findFirst({
|
||
|
|
where: {
|
||
|
|
id: roundId,
|
||
|
|
status: 'ACTIVE',
|
||
|
|
votingStartAt: { lte: new Date() },
|
||
|
|
votingEndAt: { gte: new Date() },
|
||
|
|
},
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
## Backup Strategy
|
||
|
|
|
||
|
|
### Automated Backups
|
||
|
|
```bash
|
||
|
|
# Daily backup cron job
|
||
|
|
0 2 * * * pg_dump -h localhost -U mopc -d mopc -F c -f /backups/mopc_$(date +\%Y\%m\%d).dump
|
||
|
|
|
||
|
|
# Keep last 30 days
|
||
|
|
find /backups -name "mopc_*.dump" -mtime +30 -delete
|
||
|
|
```
|
||
|
|
|
||
|
|
### Manual Backup
|
||
|
|
```bash
|
||
|
|
docker exec -t mopc-postgres pg_dump -U mopc mopc > backup.sql
|
||
|
|
```
|
||
|
|
|
||
|
|
### Restore
|
||
|
|
```bash
|
||
|
|
docker exec -i mopc-postgres psql -U mopc mopc < backup.sql
|
||
|
|
```
