🎭 Unstructured Data & Vector Architectures

🏠 Home

The Missing Piece

Traditional data architectures focus on structured data, but 80% of enterprise data is unstructured - images, videos, PDFs, audio, and text requiring specialized processing.

Unstructured Data Types

📄 Documents

PDFs, Word, PowerPoint, emails, contracts

🖼️ Images

Photos, diagrams, medical scans, satellite imagery

🎥 Videos

Training content, security footage, marketing assets

🎵 Audio

Call recordings, podcasts, voice notes, music

Vector Embedding Architecture

What are Vector Embeddings?

Mathematical representations of unstructured data as high-dimensional vectors, enabling semantic search and AI applications.

Processing Pipeline

  1. Ingestion: Raw files → Object Storage
  2. Extraction: Text/features from content
  3. Embedding: Convert to vectors (OpenAI, Cohere)
  4. Storage: Vector databases (Pinecone, Weaviate)
  5. Search: Similarity matching & retrieval

Key Technologies

  • Vector DBs Pinecone, Weaviate, Chroma
  • Embedding Models OpenAI, Sentence-BERT
  • OCR/Vision Tesseract, Azure Vision
  • Speech-to-Text Whisper, Azure Speech

Specialized Technologies by Data Type
