With these three components you access an Oracle database directly, skipping the Borland Database Engine only using SQL*Net. This gives you the following advantages:
  • No distributing, installing and configuring the BDE
  • No BDE overhead or trade offs: your queries will run up to five times faster
  • The program executable size will be more than 100K smaller
  • The use of variants makes programming easy (null values, runtime type information)
  • You can use PL/SQL blocks for server logic in your application
  • Easy to use, the components are intelligent.

  • TOCIQuery: Analog of TQuery. It must be used for executing queries to server and for editing data.
  • TOCIStoredProc: Analog of TStoredProc. It may be used for simplified usage of PL/SQL objects. TOCIQuery can also call PL/SQL. But TOCIStoredProc generate anonymous PL/SQL block and setup parameters automatically.
  • TNCSQLMonitorClient: Client of Borland's SQLMonitor. It may be used to enable NCOCI8 to trace their work into Borlands SQL Monitor.

Also 5 companion components:
  • TNCTimer: Multithreaded timer.
  • TNCDBTreeView: NCOCI8 based SQL drived DB treeview.
  • TNCCompNamer: Rule based components namer.
  • TNCDblListBox: Doubled list box.
  • TNCMemoDialog: Dialog for memo editing.
Also where are expert for component naming. You can find it in Delphi's Edit menu. Help file available. Now library is beta testing, but it is already quite efficient.
