One column per MyISAM table, I think you mean: each column in a MyISAM table would also be a column in Sybase IQ. The disk requirements in IQ would be different since IQ uses a compression technique. Since storage is column-based the compression can be done more efficiently. I work primarily at Sybase sites and everybody says that the query performance is very good. You can run into problems when loading data: only one session at a time can update a single table (many readers but only one writer)
