EAV table question

What's the best design for taxonomies in EAV tables? taxonomy id autoincrement name unique terms id autoincrement tax_id references taxonomy(id) name text unique value text relationships id autoincrement term_id references terms(id) post_id references posts(id) vs a single table: relationships post_id references posts(id) tax_name text term_name text term_value text I think that if I use a single table the db will use slightly more space, because it will store the tax name and term name for each record (relationship). But would it be faster when performing queries that select records based on multiple terms and term values?
