I'd go for a very simple table with two columns
CREATE TABLE word_docs (
unique_id INT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,
file_path VARCHAR(255) NOT NULL);
Then simply store the path of the word document. Storing binary data in the actual database can get very messy (so I've heard, never actually tried it myself). I'm almost certain the data would have to be binary or written with some sort of markuplanguage like html or XML?
