The God Blob

In the beginning
Was the Datum Singular.
Then it exploded.

A mighty bitstorm.
Data, data everywhere,
Nor any byte to eat.

When came the humans,
Order followed like a plague:
Tables, columns, rows.

Data types, oh, yes.
Varchars, numerics, long raws.
What is a long raw?

Many types they found,
Exhumed from the raw data.
Yet one was hidden.

They seek the God Blob
To make the Great Conversion.
And code freeze is near.

Long raw must be blob.
So demands the Oracle.
No. It is too hard.
