Why each option
SQL (Structured Query Language) is the standard language used to manage and query relational databases. Relational databases store data in tables with predefined schemas and relationships.
SQL is the primary language used to interact with and manage relational databases, making it inherently linked to the relational database model. Relational databases organize data into tables, rows, and columns, with relationships defined between tables based on common fields.
Excel is a spreadsheet program, not a relational database management system, although it can store tabular data.
JSON (JavaScript Object Notation) is a data interchange format, not a database type itself, although it can be stored in some NoSQL databases.
NoSQL (Not Only SQL) refers to a broad category of non-relational databases that store data in formats other than traditional tables.
