All,

One of the tables in my database has 4 columns that will hold small (under 5K) 
BLOBs. In many cases there will be no data at all in one or more of these 
columns (see sample below). Does this present any kind of problem? Should I 
split this table up into smaller tables to eliminate the NULLs (e.g. use one 
table each for IL, Phase, RL, Isolation)? I'm not sure what the best design 
choice would be.

Here is a sample of what the data will look like:

GUID            Path    IL      Phase   RL      Isolation
9a778c0e        1       BLOB    BLOB    BLOB    NULL
9a778c0e        2       BLOB    BLOB    BLOB    NULL
9a778c0e        3       BLOB    BLOB    BLOB    NULL
9a778c0e        4       BLOB    BLOB    BLOB    NULL
9a778c0e        5       NULL    NULL    BLOB    NULL
9a778c0e        6       BLOB    BLOB    BLOB    NULL
9a778c0e        7       BLOB    BLOB    BLOB    NULL
9a778c0e        8       BLOB    BLOB    BLOB    NULL
9a778c0e        9       BLOB    BLOB    BLOB    NULL
9a778c0e        10      NULL    NULL    NULL    BLOB
