How is Blob Data Stored
Go Up to What is a Blob?
Blob is the InterBase data type that can represent various objects, such as bitmapped images, sound, video, and text. Before you store these items in the database, you create or manage them as platform- or product-specific files or data structures, such as:
TIFF,PICT,BMP,WMF,GEM,TARGAor other bitmapped or vector-graphic filesMIDIorWAVsound files- Audio Video Interleaved Format (.
AVI) or QuickTime video files ASCII,MIF,DOC, WPx or other text filesCADfiles
You must programmatically load these files from memory into the database, as you do any other data items or records you intend to store in InterBase. For more information about creating a Blob and storing data into it, see Writing Data to a Blob.
