DB6ADMCON is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "DB6: Connection administration entry" Information within sap ABAP programs. This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately. i.e. DATA: wa_DB6ADMCON TYPE DB6ADMCON.
The DB6ADMCON table consists of various fields, each holding specific information or linking keys about DB6: Connection administration entry data available in SAP. These include CON_NAME (Logical name for a database connection), DBMS (Database system), USER_NAME (Database User), PASSWORD (Password for setting up the connection to the database)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
