A named database supports three access modes:
Exclusive read/write access
Shared read-only access
Shared read/write access
The first two access modes are implemented through a file server session which provides the necessary file access modes while shared read/write access must be done through the DBMS server.
Creating a database through the Create()
and Replace()
member functions of RDbNamedDatabase
, initiates client-side access to the database and does not require a connection to the DBMS server.
RDbNamedDatabase
offers two Open()
functions, one for client-side access and the other for client-server access. Client-side access is preferred over client-server
access as data retrieval is faster than indirecting via the DBMS server.
