>Hi Asif...thanks for your answer..
>What are compressed character surrogate keys?
Surrogate keys are Primary keys with no underlying meaning. They are especially usefull if you plan to use record-recycling in your database design. This means that you will never have to pack a table, the table will most often reach a terminal size, and the table will not require any periodic maintenance schemes.
>what are tables related via surrogate key?
They are child tables with the surrogate key identifying records which have a relation to one record in the parent table. Whenever, a record in the parent table is marked for deletion, the child tables are also marked for deletion. When a new record has to be added, a Stored Procedure will first try to recycle a record marked for deletion without over-writing the surrogate key in the parent table. The surrogate key(s) in the child tables may be over-written as required.
Keep in mind, that you may still need Primary or Candidate keys in your parent table which do have meaning.

To access data over a network, store the data path either in the PATH statement or in a table. If you choose to do the latter, then everytime you use a table, you must build a string on the fly with the path preceeding the table name. For example, if the CUSTOMERS table was on drive H:\123\DATA, you would call something like USE 'H:\123\DATA\customers' IN 0 SHARED
The best way to learn is to experiment.
