Power designer's Data Architect, Enterprise Architect and Information Architect

Does anyone have product differences between Power designer's Data Architect, Enterprise Architect and Information Architect?

Dear Rahaman,
Please refer to the PD 16.5 packaging options below and you can't miss the differences.
DataArchitect\DM includes Shell/Core*, XML, PDM, LDM
DataArchitect\RE includes Shell/Core*, XML, PDM, LDM, Repository
Information Architect includes Shell/Core*, XML, PDM, LDM, Repository, DMM, CDM, BPM
EnterpriseArchitect includes Shell/Core*, XML, PDM, LDM, Repository, DMM, CDM, BPM, OOM, EAM, EA Frameworks
** Shell & Core includes UI, Gap and Impact Analysis Tools, Reporting Tools, RQM, Free Model, and other common components
There exists different modeling features you can use in each of packages in PowerDesigner 16.
If you want to use a repository for storing models and sharing them with other modelers, you should have at least DataArchitect/RE option.
And, If you should use OOM, then it is required that you have the EnterpriseArchitect option.
Best Regards

CHARINDEX has a character length limitation i.e., 8000, are there any other functions in T-SQL that can be used as an alternative

Old link, but apparently PATINDEX doesn't have the same limitation as CHARINDEX

Data architect forum

Hi,
Is thr any forum, where one can discuss the project related database architect ?.
With Thanks
Umesh

Not here. The Oracle forums are focused on Oracle, not general, technology.

How can we export the Primary key values (along with other data) from an Advantage database?

One of our customers is moving from our application (which uses Advantage Database Server) to another application (which uses other database technology). They have asked us to help export their data, so that they can migrate it to another database system. So far, we have used the Advantage Data Architect (ARC32) "Export Table Structures as Code" functionality to generate SQL. We used the "Include existing data" option. The SQL contains the necessary code to recreate the tables and indexes. The customer's IT staff will alter the SQL statements as necessary for their new system.
However, there is an issue with the Primary Keys in these table. The resulting INSERT statements use AutoInc as the type for the Primary Key in each Table. These INSERT statements contains "DEFAULT" for the value of each of these AutoInc fields. The customer would like to output an integer value for each of these Primary Key values in order to maintain referential integrity in their new system.
So far, I have not found any feature of ARC32 that allows us to export the Primary Key values. We had been using an older version of ARC32, since our application does not use the latest version of ADS. I did download the latest version of ARC32 (11.10), but it does not appear to include any new functionality that would facilitate doing this sort of export.
Can somebody tell me if there is such a feature in ARC32?
Or, is there is another Advantage tool to facilitate what we are trying to accomplish?
If there are no Advantage tools to provide such functionality, what else would you suggest?

George,
It sounds like the approach you are using is the correct one. This seems to be the cleanest solution to me especially since the customer is able to modify the generated SQL statements for their new system.
In order to preserve the AutoInc values I would recommend altering the table and changing the field datatype from AutoInc to Integer. Then export the table as code which will export the actual values. After the tables have been created on the new system they can change the field datatype back to an AutoInc type if necessary.

Schema Mapping in Data Service Integrator

Hi,
I'm just examining some schema mapping programs like BizTalk, Altova and IBM Rational Data Architect, and now found Oracle Data Service Integrator which might be a similiar tool. Actually I found out about Data Service Integrator via BeQ AquaLogic, which probably had been some schema mapping tool before Oracle acquired it and now offers it as Data Service Integrator.
My question is, whether Oracle Data Service Integrator is really applicable for schema mapping/matching, such as creating mappings between xml, csv/flat files or database schemas. I already downloaded it and tried it out, but had troubles creating a map. According to a tutorial you create a physical data service if you wanna do something like mapping, but after I did this there was only a "map" with a source schema. There was no way to add a target schema and map it with the source schema.
So can I create mappings in Data Service Integrator or are there other products which would be more convenient (Oracle Warehourse Builder for instance)? If so, does anyone know whether there is a good tutorial how to map simple schemas such as xml files in Oracle Data Service Integrator?
Thank you in advance.

After you create your physical data services, create a logical data service using your target schema as the 'return type'. Then add functions and use the xquery mapper to map your physical data services (csv, database, xml, web service etc) to your target schema. You can also use logical data services as the input to a logical data service.

SSRS Date Picker Giving Error in IE

I have some ASP.NET code that has an SSRS report control on page. The web application is hosted on a different server than where SSRS is hosted. The problem I'm having is when I pull up the report in
Internet Explorer the date picker control is not showing the calendar and if I try to pull up the report in
Chrome the date picker control doesn't show up at all. If I type dates into the text boxes, the report works just fine but, we would really like to be able to use the date picker control.
Any ideas as to what could be wrong?

Your title says IE but the post says Chrome.
Take a look at this for Chrome:

Degree of Data Normalization

Hi Friends,
Is data normalization the same as database normalization? Is this part of the work of DBA?
How many forms or level does data normalization has? Is it up to 5th or 6th level?
I have been hearing this Data Normalization and I tried reading it over and over but I can not really fully understand it :(
Thanks a lot
Ms K

Hi,
it can assigned to more roles. If the team/project is small it is the DBA, but if bigger there can also be a Data Architect or some Functional Designer who can do the job (initially). I also saw that a good senior programmer (sql/plsql) can do the job, but experience is an advantage. But with good thinking and looking at the requirements, all the above mentioned roles can do the job. But finally the DBA has (normally) the last word, because he has to implement the design. The DBA afterwards has also to make the Technical Design of the database.

LiveCycle and Excel Data

I am relatively new to LiveCycle and I have looked across the forums but haven't found solid answers to what I am trying to do therefore I was wondering if someone is able to answer my questions:
1. Can you setup a LiveCycle for so that it will read from a set of Excel data files (or converted CSV/XML files) at the time you launch the PDF with a LiveCycle form in it. We intend to create Graphs and Charts from the data and wanted it so that for these to be updated, all that needs to happen is that the data files are overwritten with a new set of data. Can LiveCycle do this, or does the data get embedded in the PDF at the time that the PDF file is published??
2. Could you put the PDF onto Microsoft Sharepoint and have the data files in a document library and then have the PDF form read the data from these files within the document library?
Thanks for any help with these questions.

Are you saying publish the PDFs using a LiveCycle server? I know you can use LiveCycle server to initiate workflows that would include what you are asking but I have no experience in this.
I use VB.net with an iTextSharp plugin to deploy all our forms. It takes the PDF and imports XML generated by our data architect from a shared drive to generate many PDFs into a production environment.

Regarding AIA Reference Models

Hi,
I have installed BPA Suite with Business Process Architect and the Publisher.
I am able to import and export the models developed in the Architect as XMLfiles.
Even I am able to export the models to the publisher also.
I would like to see whether I can import the AIA Reference models to the architect and then export the same in to the publisher.
Could any one help me on where I can find the AIA Reference models (will it come with the installation or can I download it)?
what will be the format of the AIA reference models (xml or some other).?
Thanks,
Anju

Bw implementation phases

Hi gurus,
In a bw implementation project 5 phases are there.
As a bw consultant in that five phases what is our responcibilities.
points will be assigned.
Thanku

Hi Chinnu,
Phase 1: Upgrade Project Preparation -
The purpose of this phase is to provide initial planning and preparation for your R/3 upgrade project. Although each upgrade project has unique objectives, scope and priorities, the steps in Phase 1 help identify and plan the primary topics that must be considered.
Phase 2: Business Blueprint -
The purpose of this phase is to establish a common understanding in your company about how the new R/3 release will handle your current business processes after the R/3 upgrade.
Phase 3: Realization of DEV and QAS -
The purpose of this phase is to perform the upgrade of all non-production R/3 Systems, which normally include development (DEV) and quality assurance (QAS) systems, and to ensure the quality of this upgrade process by comprehensive testing. You need to upgrade your DEV and QAS systems before performing the upgrade for your production system (PRD). Furthermore, you will develop your end user documentation and training in this phase.
Phase 4: Realization of Production -
The purpose of this phase is to complete the final preparation for the upgrade of the production R/3 System, and end user training, if necessary. On the successful completion of this phase, you are ready to run your business in your upgraded production R/3 System.
Phase 5: Go Live and Support -
The purpose of this phase is the transition from your previous R/3 System to a newly upgraded and improved R/3 System. Be aware that you must set up an ongoing support organization to service your R/3 users, both during the first few days of your upgraded production operations, and on an ongoing basis.

Responsibilities of an implementation project...
For ex, Lets say If its a fresh implementation of BI or for that matter you are implementing SAP...
First and foremost will be your requirements gathering from the client. Depending upon the requirements you will creat a business blueprint of the project which is the entire process from the start to the end of an implementation...
After the blue print phase sign off we start off with the realization phase where the actual development happens... In our example after installing the necessary softwares, patches for BI we need to discuss with the end users who are going to use the system for inputs like how they want a report to look like and what are the Key Performance Indicators(KPI) for the reports etc., basically its a question and answer session with the business users... After collecting those informations the development happens in the development servers...
After the development comes to an end the same objects are tested in quality servers for any bugs, errors etc., When all the tests are done we move all the objects to the production environment and test it again whether everything works fine...
The Go-Live of the project happens where the actually postings happen from the users and reports are generated based on those inputs which will be available as an analytical report for the management to take decisions...
The responsibilites vary depending on the requirement... Initially the business analyst will interact with the end users/managers etc., then on the requirements the software consultants do the development, testers do the testing and finally the go-live happens...

RE: (forte-users) RE: Forte' vs J2EE

Hi Alexandra,
1) Forte 4GL and FJEE (Forte for Jave Enterprise Edition) are tools.
2) TOOL and Java are languages.
3) TOOL is proprietary and Java is public.
4) J2EE is a proposed, Java-based achitecture. Not a tool, not a language,
not a standard.
5) J2EE looks a lot like the architecture already supported by Forte 4GL,
however J2EE is explicetaly based on Java, EJB, JSP, JDBC and Servlets.
There are 3 versions of Forte for Java. The "Consumer Edition (CE)", the
"Internet Edition (IE)" and the "Enterprise Edition (EE)". CE is really a
remake of "NetBeans" and can be downloaded for free. IE and EE do not exist
yet. However, EE should be a remake of SynerJ, Forte's first Java tool.
You quoted someone who was very negative about Forte. I don't think that's
deserved. He's probably someone who simply didn't manage to understand the
tool. However, he is right in complaining about the support of Forte 4GL.
And it's true that the version people are currently using is at least more
than 2 years old and outdated. Since this period, there have been some
bugfixes, but hardly any real improvements.
From the description of your application, I would really advise to use Forte4GL. However, the lack of improvements, new releases, press releases, etc.
has me worried about the future of that product.
One of the real disadvantages of Java is performance. Java is very slow and
requires very heavy hardware to perform acceptably. Swing is a GUI framework
based on Java, which is notoriously slow even by Java standards. FJCE
development GUI is based on Swing. Download this product, install it and run
it and you'll see what I mean.
Forte applications can run in 2 modes. Interpreted or compiled. If they're
compiled, they're turned into platform dependent executables, which perform
really well. If they're interpreted, they're running inside a Forte Virtual
Machine, which performs less well, but still very acceptable. Java
applications run only in Java Virtual Machines and perform far less.
I would use Forte server side and Forte client side. For the browsers, I
would simply use any available tool to build webpages and use CGI to
interface with Forte. I would not try to use a different client side tool
that should communicate to a Forte server side.
Express is a good tool for developing CRUD (Create Read Update Delete)
applications based on an existing, and relatively static, database model. I
don't know about Rapport. However, don't be fooled into believing that
Express makes it easier for unexperienced developers to build Forte
applications. If anything, it makes it harder. A common look and feel can
easily be achieved by agreeing on the look and feel of windows during the
design-phase, and have all developers conform to this standard. It really
isn't that hard. Just don't create very large window class trees. That
causes strange behaviour.

Alexandra I presume.
Excuse me for asking but isn't J2EE just a STANDARD? And Forte aprogramming
language that may or may not adhere to that standard?
Now to the question, if the C++ experience is good - what's wrong withusing
C++?
Do you need to build component based distributed systems? Then hire saytwo
experienced architects - to design a practical model (UML perhaps).
Are there already good systems around you could tailor for your needs?
Just a few questions that need to be addressed to make an informeddecision.
What business are you in (your team/company)? If it's not IT then ask
yourself why do it inhouse?

Dirk
PS: What country and from where is the Forte support? You mean peoplecode
in a language other than English?----------------------------------------------------------------------
Well, Forté is certainly not a programming language, TOOL is the
language for the Forté 4GL environment.
J2EE is a standard, and there are already some Application servers
that
implement it (as I was told, webSphere, Iplanet and weblogic,
sorry if I am missing someone).
I really do not know the standard, and I am not sure it says it will
have to be implemented in Java, but all these 3 application servers
do it in Java...
The C++ experience is only from part of the team, and is not from
Database applications, the type of application we are doing is not
well suited to do in C++, we all agree, C++ is out of the question.
I have received many answers (not posted in this mailling list
unfortunatly) telling me that Java is best, others told me Forté is
good Java is just a promise, but they really did not know Java
very well, someone even said:
Forte 4GL sucks terribly. It is not supported well by what
is left of 'Forte the company'.
The tools for this proprietary environment suck.
No distributed debugging or profiling!
There is really no adequate profiling support at all
Avoid Forte like the plague that it is.
Any way, a Forté person told us that Forté is good, precisely, for
our kind of application, and as some people made more questions about
it, I am explaining better our application:
- We are doing this application because we are an IT company, our
job is to make and sell back-office applications for the finance
sector (accounting, third-party, bank management, credit
management), now we want to make one application with all of these.
In simple terms we can define it as an ERP for Credit Operations.
- The users will be in-house except for a small set of
functionalitty, which will be available through browsers.
The front-end should run in an ordinary PC running WINDOWS (we
were told that Java is too heavy and PC's should have at least 256Mb
RAM, which, I believe, is to much for all our clients)
If this is true, it puts Java clients (with Swing) or Java applets out,
HTML, we believe is not powerfull enough for all the interface.
The server, will have to work well with about 300 simultaneous
internal users, plus some Web ones (do not know how many)
The application must be multi-lingual, that is, it should be easy to
put it in any language.
The application is based on a big database, with more than 500
tables, some with about 100 columns, some with millions of records.
- We want to be sure that the application will have the same layout
(look and feel) in every screen, so it will be nice something to
generate code or to create similar functionality (table screens,
for instance) in an automatic way ( that is why we are considering
Express for it). Of course this will help also the maintenance of
the sources.
Our questions are:
FORTÉ or JAVA for the server-side.
Which tool for the client-side?
Which framework to use?
-Express or Rapport from albion if using Forté?
-Are there any good frameworks for Java ?

Gabriel,
I disagree with you on one very important point. You say it's nearly
impossible to predict anything about the future in ICT-world, so it's better
to not predict at all and only look at the here and now. Here and now, Forte
is better than Java. So, the best choice would be Forte.
But you also mention that Forte is best suited for big projects. Big
applications usually have a long lifetime. Many of the current Forte
applications are the legacy systems of tomorrow. While all the VB, Access,
ASP and Java crap that's being produced will be replaced within 6 to 18
months, Forte applications will live for years.
Migrating such large applications to a new environment, even if this
environment is using a similar technology, requires very high investments.
Companies will want to avoid this as much as possible. So, they'll want to
invest in technology that can evolve with the rest of the world. As
operatingsystems change, databases change, middleware architectures become
obsolete (DCE) and new ones are created (EJB), end user interfaces evolve
(from text to GUI to Web), requirements change (data-oriented,
process-oriented, eCommerce), etc.
Of course, flexibility is not only achieved through technology. A good
design is probably more important.
Managers, not developers, will have to make the strategic decisions about
where to spend their millions. So, they have to look at the future, no
matter how hard that is. At the moment, Forte is still superior, even though
it hasn't been truly improved for over 2 years and that's pretty impressive.
Java is still very "hyped" and no one knows what's going to happen to it.
But the future of Java looks much brighter than the future of Forte. If
Forte doesn't put some serious effort in product development and marketing,
like now, the future of this product suite looks very bleak indeed. And I
wouldn't want to spend my millions knowing I have to do it all over again 2
years from now.
Keeping an eye on the future, where the only certainty is change, I would
not focus on platform independance. I would focus on language independance.
CORBA seemed like a very good idea 2 years ago, but it turned out to be too
complex, technical and inflexible. I would definately go for a CBD
architecture, using XML as backbone. XML can be exchanged between components
using HTTP, CORBA, DCOM, FTP, file copy, DCE, C/C++ call in/out, RMI, IIOP,
E-mail, MQSeries, etc. etc. Or any mixture of these systems.
The role of the data architect will become much more important than the role
of the application architect. The choice for a language or tool is reduced
to "the best choice here and now" as long as you design your large
application as loosly coupled components. It's OK if all of these components
are Forte and they're all communicating using Forte native RMI's. As long as
the design is sound, it's not going to be very difficult to exchange
individual components by others, built in Java, VB, Perl, Cobol++, Fortran
for Windows, or what other monsters the future might bring. The only thing
that binds them, is the datamodel (NB: datamodel is not the same as
databasemodel)
I do worry about the trend to use very large, omni-present, closed,
non-component architectures, like the current ERP applications. This locks
organisations into a single, expensive and hard to maintain technology.
However, it is an opportunity for us, OO - C/S - CBD developers, to build
bridges, adapters, wrappers and gateways to hook these systems into the rest
of the organisation.

Subject: Re: (forte-users) RE: Forte' vs J2EE
If I were you, I would also consider this very important issue ( I think
it's the same for all 4GL users ), WILL THERE BE FORTE 4GL 5.0?I wonder every time I see that... Why is this that important?
(my mail is long.. if you don't like long mails, delete it now :) )
Let's see from the business' point of view:
If you would like to have an application implemented now,
use now, then you choose an environment existing now.
Now Forte 4GL seems to be a better alternative than Java,
because of the issues mentioned by others already.
I seem to be short-sighted, but could anybody tell me
with 100% accuracy, what will happen to Java in two years?
I doubt...
Forte did not changed too much in the last two years, and
still rocks, at least compared to other existing enterprise
level alternatives. So, nothing has changed that dramatically.
If you look behind the marketing-hype, you will probably agree.
I think, for the next two years Forte will be good enough for us too.
And what then? We will find out then, not now. Anybody, who tries to
explain you what will be in two years in the IT, almost certainly lies :)
Of course, using a "two years old technology" is not that cool from the
marketing point of view, but you use a solid technology, most likely
bug-free,
or at least having only known bugs. That is technically important!
If you ask about investment protection ... ?
Forte is very good in this subject too. If you look at it, you will see, it
is
sold as an integration solution (Fusion, Conductor, etc...)
If something is sold as an integration tool, it should be not that difficult
to
integrate :) Forte supports the most important standards, existing now.
If your future system supports it (it should), it will be easy to upgrade to
it,
using the existing product,know-how, etc... Probably without noticeable
downtime.
Scalability issues: Forte scales well from big to very-big to ultra-big.
What is big, you have to decide :)
For example, one million mails per day is not big. :)
For small businesses Forte isn't good. Java is. And a lot of other
environments
are, for example Perl, Python, etc...
My personal opinion is that our future will be heavily influenced by free
software.
They are very good already, and will be only better.
As Forte evolves, one important step would be to port it to free (and thus
independent)
OS's and DB's like Linux or FreeBSD and Postgres or Mysql. Even without
warranty!
I can't see what Sun's goal is with Forte, maybe they wouldn't
like this idea at all, since that may be the market segment what their Java
is thought for.
But that would be the perfect investment production as the company grows,
they don't have
to do anything to the software, just buy machines, and play around in
Environment Console :)
From the personal point of view:Although I don't work with Forte in the moment, I did this till last year,
and I will do
that in the next year too :)
If you would like to protect your "investment" and/or "market value" then
try to learn
platform and language independent things. I think, knowing Forte is 25%
platform dependent
knowledge (so useless anywhere else) and 75% platform independent. Using,
analysing, designing,
programming, and living OO is absolutely platform independent.
Project (and self-) management, presentation techniques, design and
documentation practices, version
and revision management, and so on, they are all platform independent.
Furthermore if you quit the Forte world, and have to program f.e. Java, you
will learn it in weeks.
JFC, Swing, et. al. are nothing, if you know OO. You just need a book or
an online manual, and you
can write programs in the first week. You will have much more problems with
the working environment,
and you will wonder, how the others can use that crap... after the smart
Forte IDE :)
Back to business a bit:
One big advantage of Forte, that came to my mind right now is that you can't
(ok, you can, but it is
difficult) to write bad OO programs (and designs). In Java, it is too
easy... believe me, I saw some examples ... :)
Sorry for the bad english and the long mail...

Responsibilities of an implementation project...
For ex, Lets say If its a fresh implementation of BI or for that matter you are implementing SAP...
First and foremost will be your requirements gathering from the client. Depending upon the requirements you will creat a business blueprint of the project which is the entire process from the start to the end of an implementation...
After the blue print phase sign off we start off with the realization phase where the actual development happens... In our example after installing the necessary softwares, patches for BI we need to discuss with the end users who are going to use the system for inputs like how they want a report to look like and what are the Key Performance Indicators(KPI) for the reports etc., basically its a question and answer session with the business users... After collecting those informations the development happens in the development servers...
After the development comes to an end the same objects are tested in quality servers for any bugs, errors etc., When all the tests are done we move all the objects to the production environment and test it again whether everything works fine...
The Go-Live of the project happens where the actually postings happen from the users and reports are generated based on those inputs which will be available as an analytical report for the management to take decisions...
The responsibilites vary depending on the requirement... Initially the business analyst will interact with the end users/managers etc., then on the requirements the software consultants do the development, testers do the testing and finally the go-live happens...
