table buffer means all records available in presentation server data access is faster than the main table transparent and pool table can be used as a buffer 

They are seven technical properties   they are      Delivery Class: it is used to control the transport of table data. it is used to specify the type of the table 1. we mostly used to delivery class c 2. In case of delivery class c, the table can maintain any environment development quality production system using sm30 Data browser table view maintenance: this properties specify whether the table can maintain or not we mostly specify table maintenance allow   table maintenance allow with restriction table maintenance now allow Data class: it is used to specify the type of data to maintain master data translation data organization data   APP0, APP1 Size category: it is used to specify the initial space required to table mostly we can use to 0 in case size category more than 0 table automatically adopted a new size of the table Buffering: it is used to control the traffic of database that is buffering not allow buffering allow with restriction buffering allow 1. single r
