| Why do we have to use a VSAM file when we can use a DB2 table. ? . |

| You don't have to use a VSAM, but some shops still prefer them to DB2. |

Cost! It cost more to use DB2 and you may have existing processes that use VSAM and the users don't want the extra cost to convert them. |

| Its can also be a big pain in the neck to develop against DB2. Shops will usually allow developers to create their own VSAM for testing with, but they will only let DBAs create new tables or alter tables after going through a design process. My shop is still heavily VSAM for just that reason. Using DB2 would slow development and testing to almost a crawl. |
