+## **PostgreSQL Hosting: OCI Always Free + Home Lab Hybrid**
+
+**Primary Setup: OCI Always Free Tier**
+- Deploy PostgreSQL on the Arm-based Ampere A1 (4 cores, 24GB RAM)
+- This gives you a production-grade, always-available database
+- 200GB block storage is plenty for grants data
+- 10TB monthly data transfer handles all your API calls and client deliveries
+
+**Backup/Development: Home Lab**
+- Keep a local PostgreSQL instance for development and testing
+- Use it for experimentation without affecting production
+- Disaster recovery backup location
+
+**Why This Hybrid Approach:**
+- **Cost**: Truly free forever (not 3-month AWS trial)
+- **Performance**: 24GB RAM handles massive datasets easily
+- **Reliability**: Cloud uptime for client-facing services
+- **Security**: Your production data isn't on your home network
+- **Scalability**: Room to grow without cost jumps
+
+## **Database Schema for Grants Intelligence**
+
+### **Core Tables Structure**
+
+```sql
+-- Raw grants data from Grants.gov
+CREATE TABLE raw_grants (
+    opportunity_id VARCHAR(50) PRIMARY KEY,
+    opportunity_number VARCHAR(100),
+    opportunity_title TEXT,
+    cfda_number VARCHAR(20),
+    cfda_title TEXT,
+    funding_agency_code VARCHAR(10),
+    funding_agency_name VARCHAR(200),
+    award_ceiling DECIMAL(15,2),
+    award_floor DECIMAL(15,2),
+    posted_date DATE,
+    close_date DATE,
+    last_updated_date TIMESTAMP,
+    opportunity_category VARCHAR(50),
+    funding_instrument_type VARCHAR(100),
+    eligible_applicants TEXT[],
+    description TEXT,
+    version_nb INTEGER,
+    raw_xml_data JSONB  -- Store original XML for reference
+);
+
+-- Processed grants with intelligence flags
+CREATE TABLE processed_grants (
+    id SERIAL PRIMARY KEY,
+    opportunity_id VARCHAR(50) REFERENCES raw_grants(opportunity_id),
+    target_region VARCHAR(20), -- TX, OK, AR, etc.
+    sector_category VARCHAR(100), -- Health, Education, etc.
+    size_category VARCHAR(20), -- Small (50K-250K), Medium (250K-1M), Large (1M+)
+    competition_level VARCHAR(20), -- Low, Medium, High (based on historical data)
+    win_probability_score DECIMAL(3,2), -- 0.00 to 1.00
+    strategic_notes TEXT,
+    client_matches TEXT[], -- Array of client IDs this matches
+    created_at TIMESTAMP DEFAULT NOW()
+);
+
+-- Historical award winners from USAspending.gov
+CREATE TABLE award_winners (
+    award_id VARCHAR(100) PRIMARY KEY,
+    cfda_number VARCHAR(20),
+    recipient_name VARCHAR(300),
+    recipient_state VARCHAR(2),
+    recipient_zip VARCHAR(10),
+    award_amount DECIMAL(15,2),
+    award_date DATE,
+    funding_agency_name VARCHAR(200),
+    project_title TEXT,
+    project_description TEXT
+);
+
+-- Client profiles and preferences
+CREATE TABLE clients (
+    client_id SERIAL PRIMARY KEY,
+    organization_name VARCHAR(200),
+    contact_email VARCHAR(100),
+    target_regions VARCHAR(10)[],
+    focus_areas VARCHAR(100)[],
+    min_award_size DECIMAL(15,2),
+    max_award_size DECIMAL(15,2),
+    cfda_preferences VARCHAR(20)[],
+    subscription_tier VARCHAR(20),
+    created_at TIMESTAMP DEFAULT NOW()
+);
+
+-- Weekly intelligence reports
+CREATE TABLE intelligence_reports (
+    report_id SERIAL PRIMARY KEY,
+    client_id INTEGER REFERENCES clients(client_id),
+    report_date DATE,
+    opportunities_found INTEGER,
+    key_insights TEXT,
+    report_data JSONB,
+    delivered_at TIMESTAMP
+);
+```
+
+### **Key Indexes for Performance**
+
+```sql
+-- Fast filtering for common queries
+CREATE INDEX idx_grants_cfda ON raw_grants(cfda_number);
+CREATE INDEX idx_grants_agency ON raw_grants(funding_agency_code);
+CREATE INDEX idx_grants_dates ON raw_grants(posted_date, close_date);
+CREATE INDEX idx_grants_amount ON raw_grants(award_ceiling, award_floor);
+
+-- Geographic and sector filtering
+CREATE INDEX idx_winners_state ON award_winners(recipient_state);
+CREATE INDEX idx_winners_cfda ON award_winners(cfda_number);
+CREATE INDEX idx_winners_amount ON award_winners(award_amount);
+
+-- Client matching
+CREATE INDEX idx_processed_matches ON processed_grants USING GIN(client_matches);
+```
+
+### **Intelligence Views for Quick Analysis**
+
+```sql
+-- Texas health grants under $2M
+CREATE VIEW tx_health_opportunities AS
+SELECT rg.*, pg.win_probability_score, pg.competition_level
+FROM raw_grants rg
+JOIN processed_grants pg ON rg.opportunity_id = pg.opportunity_id
+WHERE rg.cfda_number LIKE '93.%'  -- Health & Human Services
+  AND rg.award_ceiling <= 2000000
+  AND pg.target_region = 'TX'
+  AND rg.close_date > CURRENT_DATE;
+
+-- Weekly trend analysis
+CREATE VIEW weekly_funding_trends AS
+SELECT 
+    funding_agency_name,
+    COUNT(*) as new_opportunities,
+    AVG(award_ceiling) as avg_award_size,
+    SUM(award_ceiling) as total_funding
+FROM raw_grants 
+WHERE posted_date >= CURRENT_DATE - INTERVAL '7 days'
+GROUP BY funding_agency_name
+ORDER BY total_funding DESC;
+```
+
+## **Data Pipeline Architecture**
+
+### **Weekly ETL Process**
+1. **Extract**: Download Grants.gov XML files
+2. **Transform**: Parse XML, clean data, calculate intelligence scores
+3. **Load**: Insert into PostgreSQL with conflict resolution
+4. **Analyze**: Update processed_grants with new insights
+5. **Report**: Generate client-specific intelligence reports
+
+### **Client Intelligence Queries**
+```sql
+-- Find grants matching a specific client profile
+SELECT rg.opportunity_title, rg.funding_agency_name, 
+       rg.award_ceiling, rg.close_date, pg.win_probability_score
+FROM raw_grants rg
+JOIN processed_grants pg ON rg.opportunity_id = pg.opportunity_id
+WHERE pg.client_matches @> ARRAY['client_123']
+  AND rg.close_date > CURRENT_DATE + INTERVAL '30 days'
+ORDER BY pg.win_probability_score DESC;
+```
+
+This schema gives you:
+- **Scalability**: Handle millions of grant records
+- **Flexibility**: Easy to add new data sources (SAM.gov, etc.)
+- **Performance**: Fast queries for client reports
+- **Intelligence**: Built-in scoring and matching systems
+- **Growth**: Room to add more sophisticated analytics
+
+The OCI setup gives you enterprise-grade infrastructure at zero cost, while the schema design supports both your immediate needs and future expansion into contracts, more sophisticated AI analysis, and larger client bases.
