رد: استفسار عن Blob و Guid
in Blob you can store Annotations,Dimensions,pictures and any Multimedia
GUID: it stores a unique string data in 36 characters between 2 brackets to identify a feature or table row within a geodatabase and across geodatabases
finally Databases with a native GUID data type such as personal geodatabases and ArcSDE geodatabases in Microsoft SQL Server stores Global ID and GUID values as 16 bytes. Databases without a native GUID data type store them as 38 bytes.
