To analyze user activity across multiple months, a self-join approach in SQL is preferred over separate joins, as it optimizes performance significantly. By matching records on MemberID and counting members in valid month pairs, one can efficiently identify active users without extensive resource use. Proper indexing further enhances this method.

Large Language Models (LLMs) are pretrained on vast datasets to understand language and various concepts. Enterprises often fine-tune these models for specific domains. Techniques like full fine-tuning and Parameter-Efficient Fine-Tuning (PEFT) optimize model adaptation while minimizing costs and risks like catastrophic forgetting. Understanding these strategies is essential for AI applications.
