GNUe is an n-tier client server enterprise system. The user interface
is provided by GNUe Forms client. The GNUe Forms client talks directly to the
GEAS (enterprise application server) using CORBA technology. GEAS currenty
connects to SQL92 relational databases using API calls. GEAS also manages the
business objects which consist of data and business rules.
</p>
<p>
! The backend use of a standard SQL92 relational database provides
standard interfaces for external systems and leverages current IT practices and
staff. This was an important consideration for simplifying the migration to
GNUe and the integration of GNUe with other systems (<a
href="#GNUe-FAQ-2.15">see 2.15</a>). For 2-tier backend support includes DB2,
Oracle, MySQL, and PostgreSQL. For n-tier support only MySQL and PostgreSQL
are supported at this time.
</p>
<p>
The current GNUe software components are:
</p>
<ul>
! <li>
! GNUeF - GNUe Forms </li>
! <li>
! GEAS - GNU Enterprise Application Server</li>
! <li>
! GNUeR - GNUe Reports </li>
! <li>
! EWOK - GNUe Enterprise Wide Office Kommunications </li>
</ul>
<p>
Internally, GNUe n-tier is object based. The objects contain data and
business rules with data stored in an SQL database. The business objects are
accessed using CORBA and we use Python-orbit for binding Python to our current
ORB ORBit. Therefore the business rules are written in Python. Since other
bindings exist, a developer is not necessarily limited to Python.

A large system may have multiple SQL, GEAS, CORBA name and Report
servers all running on different machines.
</p>
<p>
! <a name="GNUe-FAQ-2.2"></a><b>2.2 - What is GNUe Forms (GNUeF)?</b>
</p>
<p>
! GNUe Forms is the primary user interface to the GNU Enterprise system.
It is comprised of a user interface client called "GNUe Forms" and a
form designer client called "GNUe Form Designer."
</p>
<p>
! GNUe Forms Client is responsible for displaying output and accepting
user input. All user interaction with the system will be handled by the GNUe
Forms client. The form definition files are XML format and stored on a central
server or locally. Forms can operate directly with a RDMS server is 2-tier
mode or through GEAS in n-tier mode.
</p>
<p>
! The future GNUe Forms Designer will allow a developer to produce the
XML based form definition files utilizing a graphical user interface (GUI).
</p>
<p>
! <a name="GNUe-FAQ-2.3"></a><b>2.3 - What is GNUe Application Server
(GEAS)?</b>
</p>
<p>
GEAS is a data abstraction layer and allows GNUe to utilize single API
to all data sources (local and remote). So the client has one set of calls it
uses, but can access different vendors SQL databases or even CVS or XML files.
Similar to Borland's Database Engine or other data abstraction tiers. GEAS is
transparent to the user. It will run with multiple instances and do load
balancing. GEAS is required for n-tier operation.
</p>
<p>
! <a name="GNUe-FAQ-2.4"></a><b>2.4 - What is GNUe Reports (GNUeR)?</b>
</p>
<p>
GNUe Reports shares many features with GNUe Forms. It is comprised of a
report designer and a client that generates the requested output. Report
definition files are also XML based. And programs can communicate directly with
the XML reports definition language much like they can with GNUe Forms. The
major difference is that GNUe Reports is optimized to handle large amounts of
data and run separately from the GNUe Forms Client.
</p>
<p>
! <a name="GNUe-FAQ-2.5"></a><b>2.5 - What is GNUe Enterprise Wide Office
Kommunication (EWOK)?</b>
</p>
<p>
Integration of non-transaction based ad-hoc communications utilizing
fax, email and paging other non-network communications with GNUe. Transaction
based external communications (EDI and XML-EDI) will utilize the <a
href="#GNUe-FAQ-2.7">Data Transformation</a> Tool. To use EWOK the user would
typically hit the EWOK button in the Forms client and a pop-up window would
appear with destination and information selection options. This may be
replaced with Bayonne. This change is in process, see the news section for
more information.
</p>
<p>
! <a name="GNUe-FAQ-2.6"></a><b>2.6 - What database does GNUe require?</b>
</p>
<p>
GNUe n-tier (GEAS) currently works with MySQL and PostgreSQL relational
databases. (See <a
href="http://www.gnuenterprise.org";>http://www.gnuenterprise.org</a>). GNUe
2-tier does the same and also works with Oracle and DB2. The internal
structure of GNUe GEAS is object based but stores information in a standard
SQL92 relational database. It is anticipated that GNUe will interface to any
SQL92 (odbc, oracle, sybase, interbase, etc) standard relational database. The
API design does not limit the storage to RDMS.
</p>
<p>
! <a name="GNUe-FAQ-2.7"></a><b>2.7 - What is Data Transformation
Tool?</b>
</p>
<p>
This tool will handle all incoming and outgoing data transformation
requirements including EDI, XML-EDI, spreadsheet import/export and others.

<p>
! <a name="GNUe-FAQ-2.10"></a><b>2.10 - What GUIs work with GNUe?</b>
</p>
<p>
GNUe currently supports (some are tested more than others) win32, gtk,
motif, curses and mac GUI. A Java client is being authored as well and a web
client is anticipated in the very near future.
</p>
<p>
! <a name="GNUe-FAQ-2.11"></a><b>2.11 - What about Mozilla, Java, XUL or
some other technology</b>
</p>
<p>
If you want Java, LinuxKontor is probably a better choice for you.
Because of its popularity, some of the GNUe team is working on a Java client
(although it is not a priority). We do know that Java works with GEAS. However,
Java is NOT the preferred language as it has issues with its ownership. Because
this is a free software project we will provide all functionality using free
software.

<p>
! <a name="GNUe-FAQ-2.2"></a><b>2.2 - What is GNUe-Forms and
GNUe-Designer?</b>
</p>
<p>
! GNUe-Forms is a platform and UI-independent forms system. It reads an
! XML-based forms definition and creates GUIs for Win32, GTK, and, soon,
! Curses and HTML. It has a fully data-aware widget set and can be used in
! both 2-tier and n-tier environments.
</p>
<p>
! GNUe-Designer is the IDE for the GNUe tools. It allows you to visually
! layout your forms in a RAD-style environment. Designer has a builtin forms
! client, so you can quickly test your forms while still in Designer.
! Designer also now has support for form creation wizards... answer a few
! questions, attach your form to a table, select the fields to include, and,
! voila, a basic form is created.
</p>
<p>
! <a name="GNUe-FAQ-2.3"></a><b>2.3 - What is GNUe-Common?</b>
</p>
<p>
! GNUe-Common is the basis for the GNUe tools, such as Forms, Reports, and
! Designer. It implements a database-abstraction layer that provides support
! for most major databases. A builtin XML-to-Object parser and Object-to-XML
! marshaller are used by Forms, Reports, and Designer to save and read
! Forms/Report definitions to and from an XML file. Work has begun on an
! RPC-abstraction layer that will allow server processes to define their
! public methods once and have them available to CORBA, XML-RPC, SOAP, and
! DCOM clients.

BTW: For a designer as well people often ask "Why not glade." I suppose we
should add why not Glade and why not xul to our FAQ as I think they are valid
questions and ones I would ask if I was new to GNUe.
</p>
<p>
! <a name="GNUe-FAQ-2.12"></a><b>2.12 - What about Windows or
Macintosh?</b>
</p>
<p>
Windows is not available yet, but it is anticipated. GEAS server works
on mac OS X. wxMac, wxGTK, and wxPython still need more development to work
effectively on OS X so the GUI does not work yet.
</p>
<p>
! <a name="GNUe-FAQ-2.13"></a><b>2.13 - What about network traffic,
bandwith and thin client?</b>
</p>
<p>
All network flow is all by ORBit. We would expect same type of traffic
as a MIDAS client or DCOM client on windows. We are middle ground bandwidth
wise and thin client wise. GNUe doesn't use bandwidth whenever you move the
mouse etc. The forms code is an XML form that is interpreted by the client. Its
only when you do an event relating to the backend that it sends traffic (i.e.
event driven). The only possible issue, we anticipate, would be latency with
internet deployment with using thin clients talking to GEAS on other side of
the world.
</p>
<p>
! <a name="GNUe-FAQ-2.14"></a><b>2.14 - How do I create a simple form and
where is it stored and run from?</b>
</p>
<p>
The form is an XML file. You can create it with any editor. Then you
can run it remotely by typing "gfclient
http://myserver.com/some_form.gfd" or locally by typing "gfclient
/path/to/file/some_form.gfd". The next phase of the project will include a
graphical form designer that will be like visual basic, Delphi or glade.
</p>
<p>
! <a name="GNUe-FAQ-2.15"></a><b>2.15 - How will external systems
interface to GNUe?</b>
</p>
<p>
External systems may interface with GNUe in two ways. The simple and
more standard way is to connect directly with the SQL backend relational
database. The downside to this method is that it will bypass all business logic
built into GNUe business objects. So some business logic will be duplicated in
the external systems. Also database tables are considered very changeable for
upgrades and extensions, therefore external systems using this method will
require more maintenance than those using the GNUe API method.

***************
*** 541,634 ****
The other way for external systems to interface with GNUe is to connect
directly to the GEAS (server) using the GNUe API. This method is not as
standard but will provide better data integrity as all data will be subject to
the business rules defined in GNUe business objects. It will also be less prone
to changes as we expect the GNUe API to change less than the SQL tables will
change.

</p>
<p>
A Business Object is an encapsulated unit of information and methods
that relate to the business. For example a customer is a Business Object. Also
a purchase order, a line item on a purchase order and a receipt against a line
item on a purchase order are all Business Objects related to each other.
Business objects are defined by the developer in .gcd files. The .gcd file may
also define methods and triggers for the Business Objects.
</p>
- <p>
- The data format of the .gcd file is:
- </p>
- <p>
- <font face="Courier New,Courier,Monaco">CLASS classname { unsigned
datatype name <format>; };</font>
- </p>
<p>
! CLASS - is a reserved literal that identifies the definiton of a
business object.
</p>
<p>
- classname - is the name of the busines object being defined.
- </p>
- <p>
- {} - delinates the business object definition and may contain many
fields and method definitions.
- </p>
- <p>
- unsigned - is optional and only applies to some datatypes.
- </p>
- <p>
- datatype - is one of the following:
- </p>
- <ul>
- <li>
- char </li>
- <li>
- text </li>
- <li>
- int16, int32, int64</li>
- <li>
- object </li>
- <li>
- float </li>
- <li>
- bool </li>
- <li>
- date </li>
- <li>
- time </li>
- </ul>
- <p>
- name - is the name of the data or field.
- </p>
- <p>
- <format> - is optional and specifies the format of the datatype
(currently only applies to text and char).
- </p>
- <p>
- A Business Object without methods could be defined as follows:
- </p>
- <p>
<font face="Courier New,Courier,Monaco">class contact
<br>
{
<br>
! text businessname;
<br>
! int age;
<br>
! object person;
<br>
! };
! <br>
! </font>
! </p>
! <p>
! <font face="Courier New,Courier,Monaco">class person
<br>
- {
- <br>
- char name<32>;
- <br>
- char addr1<80>,addr2<80>,addr3<80>;
- <br>
- char countrycode<2>;
- <br>
};

The other way for external systems to interface with GNUe is to connect
directly to the GEAS (server) using the GNUe API. This method is not as
standard but will provide better data integrity as all data will be subject to
the business rules defined in GNUe business objects. It will also be less prone
to changes as we expect the GNUe API to change less than the SQL tables will
change.
