        self.validation_rules = config[‘validation_rules‘]
        self.output_format = config[‘output_format‘]

    def process_document(self, pdf_path):
        pages = self._extract_pages(pdf_path)
        tables = self._identify_tables(pages)
        data = self._extract_data(tables)
        validated_data = self._validate_data(data)

Performance Optimization Techniques

  1. Parallel Processing 
    
from concurrent.futures import ThreadPoolExecutor

def batch_process(pdf_files):
with ThreadPoolExecutor(max_workers=4) as executor:
results = executor.map(process_single_pdf, pdf_files)


2. Memory Management
```python
def optimize_memory(pdf_document):
    chunk_size = 1024 * 1024  # 1MB chunks
    for chunk in pdf_document.iter_chunks(chunk_size):
        process_chunk(chunk)
