Storing Non-Scalar Data

Explore the intricacies of storing complex data in a single field during this PHP UK Conference talk. Delve into various noSQL solutions like Redis' lists, sets, and hashes, as well as MongoDB's records. Examine how relational databases support complex data storage through specific data types such as PostGreSQL's JSONB or hstore. Compare different approaches to storage, indexing, and interactions with these data types across various database engines. Learn about document stores, complex documents in relational databases, and specific implementations in PostgreSQL, Redis, and MongoDB. Discover querying techniques, indexing strategies, atomic operations, and update operators. Gain insights into schema validation and draw valuable conclusions about non-scalar data storage in modern database systems.
