Explanation:

- Option 1: Tables

- Tables are fundamental to relational databases.

- They organize data into rows (records) and columns (fields).

- Option 2: Treelike structure

- Relational databases do not use a treelike structure.

- Tree structures are typical in hierarchical or certain NoSQL databases.

Correct Answer - This option is not a characteristic of a relational database model.

- Option 3: Complex logical relationships

- Relational databases excel at managing complex relationships between tables.

- These are handled using foreign keys and joins.

- Option 4: Records

- Records are individual entries or rows within a table.

- They define the data at the intersection of a row and column.
