BLOBs and Arrays
BLOB types (Binary Large OBjects) are complex structures used for storing discrete data objects of variable size, which may be very large. They are “complex” in the sense that Firebird stores these types in two parts: a kind of hyperlink (referred to as a BLOB_ID) is stored with the owning row, while the actual data is stored apart from the row, often on one or many different database pages, keyed to the BLOB_ID.
