Transparent Table vs. Pooled Table
Pool tables is a logical representation of transparent tables. Hence no existence at database level. Where as transparent tables are physical tables and exist at database level.
Transparent table: Where the master data is stored, and which data has no frequent changes. ex: KNA1,MARA,LFA1 etc.
We can have INCLUDE AND APPEND structure in transparent table.
Pooled table: It is linear search, where data has changed frequently, it can not have foriegn key relationship, we can not INCLUDE AND APPEND structure.
