## Development Methodology

### MCP VBA Server Automation

This project showcases advanced automation using the **VBA MCP Server** (Model Context Protocol integration), enabling AI-assisted development of Access applications.

#### What Was Automated

| Component | Automation Method | Tool Used |
|-----------|-------------------|-----------|
| Database Tables | SQL DDL via MCP | `run_access_query` |
| Relationships | SQL ALTER via MCP | `run_access_query` |
| Indexes | SQL CREATE INDEX | `run_access_query` |
| VBA Modules | Code injection | `inject_vba` + `validate_vba` |
| Test Data | Bulk insert | `set_worksheet_data` |
| Saved Queries | SQL QueryDef creation | `run_access_query` |

#### Development Workflow

```
1. Database Structure Phase (MCP VBA)
   ├─ Create tables with SQL DDL
   ├─ Define relationships and constraints
   ├─ Create indexes for performance
   └─ Verify structure with list_access_tables

2. Data Population Phase (MCP VBA)
   ├─ Insert test clients
   ├─ Insert test projects
   ├─ Insert sample time entries
   └─ Verify with get_worksheet_data

3. VBA Code Phase (MCP VBA)
   ├─ Validate VBA syntax
   ├─ Inject mod_Config
   ├─ Inject mod_Navigation
   ├─ Inject mod_DataAccess
   ├─ Inject mod_Calculs
   ├─ Inject mod_Export
   ├─ Inject mod_Utils
   └─ Verify with compile_vba

4. Query Creation Phase (MCP VBA)
   ├─ Create qry_TempsByProjet
   ├─ Create qry_TempsByClient
   ├─ Create qry_TempsPeriode
   ├─ Create qry_ProjetsActifs
   └─ Create qry_StatsGlobales

5. Form Creation Phase (VBA Script)
   ├─ Import mod_FormBuilder.bas
   ├─ Execute BuildAllForms()
   └─ Manual refinement in Access UI

6. Testing & Documentation Phase (Manual)
   ├─ User acceptance testing
   ├─ Documentation writing
   └─ Screenshot capture
```

#### MCP VBA Tools Utilized

**Table Management:**
- `list_access_tables` - Schema verification
- `run_access_query` - DDL/DML execution

**Data Operations:**
- `get_worksheet_data` - Read table data with filters
- `set_worksheet_data` - Bulk insert/update
- `run_access_query` - Custom SQL queries

**VBA Management:**
- `extract_vba` - Code extraction (for versioning)
- `inject_vba` - Module injection
- `validate_vba_code` - Pre-injection syntax check
- `compile_vba` - Compile check for errors

**Backup & Safety:**
- `backup_vba` - Create backups before changes
- `list_backups` - View backup history
- `restore_backup` - Rollback if needed

#### Limitations & Manual Work Required

**What MCP VBA Cannot Do:**
- Visual form design (layout, control positioning)
- Report visual design (header/footer formatting)
- Access UI macros (different from VBA modules)
- Visual slicers and charts

**What Required Manual Work:**
- Form control placement and sizing
- Color schemes and styling
- Report page layout
- Final UI polish and testing
