An LDAP directory can be used to store information similar to a SQL database. LDAP uses a ____ database structure instead of SQL's ______ structure. Because of this, LDAP has difficulty representing m

Neither 'strict' nor 'abstract' are recognized terms for describing the structural models of LDAP or SQL databases.

'Simple' and 'complex' do not describe the database models of LDAP and SQL and have no technical meaning in this context.

This reverses the correct mapping - LDAP is hierarchical, not relational, and SQL is relational, not hierarchical.

LDAP uses a hierarchical Directory Information Tree (DIT) where each entry has exactly one parent, making it well-suited for organizational structures but poorly suited for representing many-to-one relationships. SQL databases use a relational model with tables, rows, and foreign keys that naturally support complex relationships through joins. The fundamental structural difference is the reason LDAP and SQL serve complementary rather than interchangeable roles.
