Hello all,

  • SAP has released Business Suite on ASE version 15.7.
  • All SAP application data resides in a single ASE database. There is another small database for use by SAP tools.
  • The ASE database uses a 16KB page size.
  • For ERP only (i.e. not counting CRM and the other Business Suite modules), the database contains about 80,000 tables and 170,000 indexes. This is because SAP ERP has many features and functions, all with their own set of tables. SAP customers typically run only a subset of all those functions so in practice a large part of those 80,000 tables will always remain empty.
  • All SAP tables use datarowslocking (there is an interesting historical dimension.
  • All tables names are in uppercase; some table names contain special characters, like the slash character in “/BCV/C_QATTR” (I don’t have a clue what that name means, BTW)
  • Apart from the tables, there are also about 10,000 views. No stored procedures or triggers are used.
  • SAP makes heavy use of dynamic SQL (also known as “prepared statements”).
  • Many tables have a text or image column.
  • All tables are owned by one database user (and that’s not the dbouser).
  • The ASE database is accessed through ODBC.
  • SAP makes frequent use of the built-in ASE Job Scheduler (originally added in ASE 12.5.1).
  • The ASE server uses Unicode with the utf8 character set.
