In a relational database management system (RDBMS), you must define at least one table (that is, the database schema) before any records can be inserted into the database.
True
False
True. Relational databases store information in structured tables with predefined columns and data types. Those tables-and the relationships between them-make up the schema. Because every row must conform to that structure, the tables have to be created first. Document and key-value databases may allow data insertion without a predefined schema, but an RDBMS enforces this requirement.
