Db

Selecting the right database depends on the use case, data structure, and performance needs.

Section 8: Future of Databases - trends: distributed SQL, serverless, multi-model, AI integration.

Stores data primarily in RAM rather than on a disk. This offers lightning-fast response times, crucial for real-time bidding or telecommunications. Selecting the right database depends on the use

Slow queries kill user experience. Use EXPLAIN plans to see how the DB is executing your query. Add indexes, rewrite suboptimal joins, and archive old data.

: Machine learning applications require specialized storage. Vector DBs like Pinecone, Milvus, and Weaviate store data as high-dimensional mathematical embeddings. This enables rapid similarity searches, allowing an AI to quickly scan billions of documents and find contextually relevant information. Add indexes, rewrite suboptimal joins, and archive old data

In civil and nuclear engineering, the Design Basis (DB) is a set of conditions and events that a structure or system is designed to withstand – for example, a design basis earthquake or design basis flood.

Using appropriate data types reduces storage and improves performance. For example, storing a boolean as a CHAR(1) 'T'/'F' is less efficient than using BIT or BOOLEAN. For timestamps, use TIMESTAMP (4 bytes) instead of DATETIME (8 bytes) where possible. For integers, choose INT (4 bytes) vs BIGINT (8 bytes) based on range needs. This enables rapid similarity searches

: Homeowners use creative "cover stories" like sliding panels , wall art , or mirrors to hide the box while keeping it accessible for emergencies.

Store data in JSON-like documents (e.g., MongoDB, CouchDB).
