9.3) Odapter/OpenODB: Odapter Software Components




Description

This article is from the Object-Oriented Technology FAQ, by Bob Hathaway rjh@geodesic.com with numerous contributions by others.

9.3) Odapter/OpenODB: Odapter Software Components

Odapter uses a client/server architecture, enabling
you to efficiently utilize your computing power.
Clients use the object application call interface
(OACI) to communicate with the server over the
network. The clients and server components can also
reside on the same machine.

Odapter is bundled with the following client and
server components, as shown in Figure 8:

Client Components

* Interactive Object-Oriented SQL (IOSQL)
This interface allows you to interactively enter
all Object-oriented SQL (OSQL) statements,
facilitating rapid prototyping and testing. IOSQL
provides query, administration and editing
capabilities.

* Graphical Browser (GOSQL)
The Graphical Browser is a tool that allows you to
graphically explore your database schema and
contents, and execute any OSQL statement. This tool
is designed to assist application developers by
making it easier to view and manipulate your object
model stored in Odapter.

* Windows OSQL (WINOSQL)
This PC-based interactive interface to OSQL allows
you to interactively enter all OSQL statements.

* Object Application Call Interfaces (OACI)
Odapter provides client interface libraries for the
Smalltalk and C++ object-oriented programming
languages, allowing these languages to be tightly
coupled with Odapter.

You can also write Odapter applications using any
programming language that can be linked with C
(such as Ada, COBOL, FORTRAN and Pascal). The
programmatic interface is similar to a "Dynamic
SQL" interface, and passes strings representing
OSQL statements to the Odapter server. No
preprocessors are required.
