Information Schema
The Information Schema consists of read-only views that provide information about all the tables, views, and columns in the current database server to which you have access. These views also provide information about SQL dialects (such as HCL OneDB™, Oracle, or Sybase) and SQL standards. Note that unlike a system catalog, whose tables describes an individual database, these views describe the HCL OneDB instance, rather than a single database.
