This document discusses different models for integrating content management systems (CMS) and e-commerce platforms, including their pros and cons. It outlines three main models: side-by-side, CMS-heavy, and e-commerce heavy. The side-by-side model uses separate CMS and e-commerce systems, while the other models integrate the systems to varying degrees. It provides examples of companies using each model and factors to consider when choosing a model, such as the number of products, pricing complexity, and content needs. The document concludes that all models can work but that dedicated e-commerce platforms may still be better for large retailers due to product catalog and pricing requirements.
