Thats right! (but anybody who has records larger, than 8KB should read a
book about database design. It is likely, that he has never heard about
normalization.)
This limitation is for the actual record size. Since strings have no
size limitation like in an SQL database, they use only the actual size.
If you need to store blobs, memos, text fields etc. each of them can
have a size up to 2GB.
