Difference between Nested set model and SQL

Nested set model vs. SQL

The nested set model is a technique for representing nested set collections (also known as trees or hierarchies) in relational databases. Structured Query Language (SQL) (pronounced S-Q-L; historically "sequel") is a domain-specific language used to manage data, especially in a relational database management system (RDBMS).

Similarities between Nested set model and SQL

Nested set model and SQL have 8 things in common (in Unionpedia): Hierarchical and recursive queries in SQL, Oracle Database, PL/SQL, PostgreSQL, Relational algebra, Relational database, Transact-SQL, Transitive closure.

Hierarchical and recursive queries in SQL

A hierarchical query is a type of SQL query that handles hierarchical model data.

Relational algebra

In database theory, relational algebra is a theory that uses algebraic structures for modeling data, and defining queries on it with well founded semantics.

Relational database

A relational database (RDB) is a database based on the relational model of data, as proposed by E. F. Codd in 1970.

Transact-SQL

Transact-SQL (T-SQL) is Microsoft's and Sybase's proprietary extension to the SQL (Structured Query Language) used to interact with relational databases.

Transitive closure

In mathematics, the transitive closure of a homogeneous binary relation on a set is the smallest relation on that contains and is transitive.

Nested set model and SQL Comparison

Nested set model has 25 relations, while SQL has 158. As they have in common 8, the Jaccard index is 4.37% = 8 / (25 + 158).
