Modelling techniques & tools

Hi
What methods, diagrams and tools do you use for designing and modelling a new application (which will be implemented in Apex)?
I have used UML use cases with activity diagrams (used JDeveloper) mostly used for communication with end users and as a requirement spec.
Then I jump directly to the database modell (also JDeveloper). But that's it. This is of course ok for small development projects.
But for bigger projects I miss a link between the use cases and the data- (and object-) modell(s).
Sequence- and communication diagrams seem only valid in pure OO design...(?) ... which isn't suitable using Apex(?).
I think modelling is easier using object oriented design...
What do you think?
Any suggestions of methods, techniques and tools?
thanks // Frederic

Hi Frederic,
I'm pretty old school, probably since I've been doing this for so long. All of those diagramming tools are pretty useless to me during the desing stage, and even after I have the app/schema built, all I do is create a simple ER diagram for the users to get an understanding of the structure and relationships.
During the intial table layout, I start by sketching out the intial tables I think I'll need, then I start going through the fields I think I need and place them in the appropriate tables. I'll then throw all that in a spreadsheet and run it by the users, making a few changes or additions here and there, then run it by the users again after creating the ER diagram. I then build the app and demo that to the users and then go back and add anything else they've thought of, then update the ER diagram, tables, views, etc. and by then I'm usually pretty close to being done.
I'm probably kind of unique though in that all of my 'projects' are custom projects (schemas and apps) built from scratch, and I'm the only computer person that knows anything about they are designed and built. I just deal with scientists that have an idea of what they want, but don't have the skills to actually get it done.
My largest app though only has about 35 data tables and about 18 lookup tables, so things really aren't that complicated. If I can ever convince top level management that the current way of doing things is extremely time-consuming, error-prone and leads to eventual loss of usable corporate data though, these could easily be expanded to a couple hundred data tables to accomodate all of the types of data currently being lost each year, but I don't have much hope for top-level management ever doing anything (they hate to make decisions, especially if it involves money and/or manpower).

Modeling Techniques within SCM 4.0

Are there any reported bugs in the existing modeling techniques within APO 3.0 that have been corrected in SCM 4.0.
If they have not, are there any workarounds to get past the problem(s).
Thanks

Hi Tushar,
This is a too generic question. Very difficult to answer - suggest going through the SCM 4.0 Release Notes http://help.sap.com/saphelp_scm40/helpdata/en/36/069840893d2b54e10000000a1550b0/RN_SCM_40_EN.pdf for details to your query.

Advanced APEX Tips and Techniques (tool tip, VCF), queries...

Hi everyone,
First of all, I would like to thank the community for their help.
I have been working with APEX since a few months (December) ago, since then it has captivated most of my attention, because of what can be done with it…
This time I would like to ask for your advice about some new topics (tool tip and VCF or saving contacts) in regard to APEX, I created a calendar application –works as it meant to be- but now got some question to which I have not yet found an answer, (I have already looked on some online info).
1). Regarding to tool tip: as I mentioned before I have created a calendar application, and on it I am linking the events (specifically on calendar region) on it to some other pages, in the link that leads to the page I have put this:
select '<a title="TGB SCHEDUL" href="f?p=&APP_ID.:5:' || :APP_SESSION || '::::P5_ID: ' || ID || '">' || EVENT_NAME|| '</a>
' EVENT_NAME, START_DATE
from APP_TGB
This script does what it is meant to do link to a specific page. As I understand tool tip, if I want some message I have to place the comments on the title=''#COMMENTS#'' as I am using mozilla, as you can see I have a phrase and I would like to adjust it to every event in particular, I thought in using bind variables, so I look in google about how to create it, found how to... but no where to apply.
2). In concern to the VCF, I saw an example and tried to adjust it to my needs, but apparently I have done something inappropriate.
DECLARE CURSOR member_cur IS
SELECT id, quarter_fy08, kind_of_campaign, event_name, owner, partner, associationcollaboration, location, presales, marketing, chanel_manager, territory_manager, start_date, end_date, list, emailing, telemk, status, source_code_omo, attendees, leads, opps, budget, pipe_estimado, objetives, comments

END;
3). Referring to user groups, I have read on chapter 8, that creating groups I will be able to restrict access to various parts of an application, so I did create them and applied them but once again something happens.
Re: authorization scheme methods/techniques
What I am trying to do with the users, is to restrict their access to specific pages, so for example let's say that I do have these pages.
Start, calendar, insertion, update and report, on the start page I have a link to the insertion page, that I want it to be accessed just by those users who have some privileges (which I understand can be done with groups, to manage who can access to a page and who can not.), and to allow other user to go around to the allowed areas.
I do appreciate any kind of help or guidance.

ABOUT VCF IN APEX
Hi everyone,
This time I will like to ask you for some advise in regard to VCF, the picture is this.
VCF in theory is working and on practice is working more or less… I say more or less because of this…
This is a small idea of my application.
I have a test application on APEX that is a calendar to insert data, on the page where I do have the calendar I have some hyperlinks for insertion and for viewing the reports, and on the calendar itself I do have a link for updating the event.
I have assigned the VCF file to the updating page (page that is linked from the calendar) and bring in the values that are meant to be, in theory it should create the VCF file well but it does not.
The only way it does create the VCF file is when I insert a new registry, click insert and then on the status bar of the browser (in my case mozilla firefox) hit the back button, then the VCF file is created as it’s meant to be.
I will appreciate if anyone can give me a hint, a suggestion, anything :)
I will attach the code I use for the VCF file.
declare
cursor user_cur is
select ID, OWNER
from APP_TGB
where ID = :p2_ID;
l_ID number;
l_OWNER varchar2(60);
begin
htp.init; -- Wipe out the buffer
owa_util.MIME_HEADER('text/calendar; method=request');
-- Get the event information
htp.print('BEGIN:VCALENDAR');
htp.print('PRODID:-//Microsoft Corporation//Outlook 9.0 MIMEDIR//EN');
htp.print('VERSION:2.0');
htp.print('METHOD:PUBLISH');
htp.print('BEGIN:VEVENT');
htp.print('ORGANIZER:MAILTO: [email protected]');
htp.print('LOCATION: Application ' || :APP_ID);
htp.print('TRANSP:OPAQUE');
htp.print('SEQUENCE:0');
htp.print('Today is: ' || to_char(sysdate, 'yyyy-mm-dd') || ' ' || to_char(sysdate, 'hh24:mi:ss'));
htp.print('OWNER: (' || nvl(v('P2_OWNER'),l_OWNER) || ') ');
htp.print('PRIORITY:5');
htp.print('CLASS:PUBLIC');
htp.print('BEGIN:VALARM');
htp.print('TRIGGER:PT60M');
htp.print('ACTION:DISPLAY');
htp.print('DESCRIPTION:Reminder for account expiring');
htp.print('END:VALARM');
htp.print('END:VEVENT');
htp.print('END:VCALENDAR');
end;
The distribution of my pages is the following:
1. pag_inicio, the form of referring to it is p1_”any-atribute”… on this page there are the hyperlinks (insertion and report viewing) and the calendar itself.
2. pag_insertion, the form of referring to it is p2_”any-atribute”… on this page there are the insertion fields and a VCF button, create and cancel ones.
3. pag_update, the form of referring to it is p3_”any-atribute”… on this page there are the fields where the information is brought up, and a VCF, update and cancel buttons.
4. pag_report, the form of referring to it is p4_”any-atribute”… on this page you can see the fields in a report format.
5. checking_events, the form of referring to it is p5_”any-atribute”… this page is like the updating one, but with letting the user modify any value, it has a VCF.
6. pag_VCF, where the VCF code is.
I do appreciate your help and guidance.

Does adobe have a 3d model creation tool?

Hello
My history is that i use fireworks and dreamweaver.
I am messing arround in after effects.
I would like to create similar objects like i can in fireworks only as 3d objects.
I am talking about creating shapes, extruding them into 3d space, applying styles and textures.
Only the result would be a 3d object that i could bring in to after effects where i can animate rotation and movement in 3d space or integrate it into an after effect project.
I assume that in after effects, i can create shadows from light sources so basically i want extruded text and shapes, perhaps with textures on them.
Maybe even with alpha transparency patterns painted onto their surfaces.
What about isllustrator? i have seen many cool 3d effects such as rotation and text extrusion.
Can these be exported as 3d objects that can be brought into after effects and placed in 3d space?
Or even photoshop? I think in photoshop, i can only use a small number of basic shapes.
Thanks
Jerry

You can import 3D models into After Effects if they are contained in a 3D object layer in a PSD file.
You can also use a third-party plug-in like Zaxwerks Invigorator to do exrtusions and sweeps. See this overview.
You can do some limited but very useful creation of 3D environments with Vanishing Point.

Modelling techniques

Hello !
I have been given some business objects .
i ahve to do the modelling .
I have found the strong entities . these will be treated as dimensions . There are other business objects which has a 1:1 relationship with the strong entities ?
what should i do with them ?
which are to kept as master data and which as transaction data ?How will i understand ?
Should master data be loaded from R/3 or i have maintain it in BW ?
Please help me with a scenario.

Hi,
Please search the forum. This is an excellent document on modelling alongwith examples that'll clear your doubts.

Object Oriented Modelling and Code Generator

i have a final yr project on java--any help plzz
Objectives:
In software development we make extensive use of models to capture details about objects in a domain, the attributes of the objects and the relationships between the objects. Once complete, these models also contain constraints on the objects and their attributes.
The aim of this project will be to develop a GUI to draw an appropriate software model and to automatically generate a set of Java classes consistent with the model that can be used to rapidly implement the software.
This research will aim at analysing the different modelling techniques and the mapping of these models to java codes.
note: any good advice..

Hello there..
I Together Control is one of the best tool that can serve ur purpose
this is pretty good Tool.
Specially auto code generation is cool.
Look in to borland site..( They now took overtogether ) for free eval version ..

Tool for design PI Implementations

Hi everybody,
I need to know if there is any tool to design the PI objects collaboration. I mean a tool to make a graphic which show the way in that the Pi objects are distributed.
Any help I really appreciate it.
Thanks
Ivan Reyes

PI 7.0 does not have ability to transparently gel with any modelling tool. But with PI 7.1 you can use various modelling techniques provided like ProComp models inside ESR. Other compatible tool is ARIS by IDS Scheer.

Best OLTP Reporting Tool

Hi Gurus,
My company asked me to build a reporting framework to support their needs on OLTP, i am trying to do some research on which tool is the best tool to do reporting on OLTP..
Need help to find out a best reporting tool to make reports on OLTP data base
Right now we are using OBIEE for our OLAP reporting and we are open to implement any tools, need inputs and comparisons between all the available tools and pros and cons also.
Appreciate all your inputs/suggestion.
Thanks,
Seshu.

1) I guess you tried to pull thousands or report's rows on screen. Firstly OBIEE does pagination perfectly. Secondly human being cannot handle more than 30-50 lines physically. It is simple psychology. As soon as you've jumped on other couple pages you have no idea what was on the first pages. I've never seen such an idiot who would need report even with few hundred rows. Such reports are example of bad practice.I agree with that but you missed my point. Enterprises are large "beats" and as such they have many departments where they use different tools. In an ideal world you will have one and only one DWH with one an only one reporting tool on top. The thruth is that this never ever happens in reality. So in many cases users are asked to provide larde data extracts to use as sources for other reporting systems or external entities. OBIEE can not handle these data extracts properly as it not designed to work as an "extraction tool". This is what you missed. BO can handle them very well as it was designed as an extration tool in mind.
2) Here you are right if it is all about dimensional model. However here is the difference between OLTP and data warehouse. In data warehouse users should be educated to know conceptual and logical models. BTW you are getting requirements from them and you say they don't know which dims can be pulled with facts and which ones cannot? Wow )) Also OBIEE does allow to pull such dims ( not connected to facts ) using very simple OBIEE modeling technique (level-based measures). That makes OBIEE reporting/analytics very flexible. You are only thinking dimensional. That's very good for an OBIEE developer. But the world is more than just dimensional. You can't answer all reporting requirements with a dimensional model I am afraid. So keep this in mind. A DWH is not the solution to all report requirements just like saying "a truck is the best vehicle in the world because it's big and can transport big loads". BTW have you tried to implement cross-fact analysis in OBIEE? Do you know that you need to set the content level for each non-confirmed dimension in each measure individually or OBIEE will bring back the measure as "NULL"? It's non-sense really, it's too tricky and too flaky.
3) OBIEE has GUI object called PROMPT. There you have full power to force users to apply filters. And you can easily pre-defined your prompt's filter values.Again you missed a key word on my statement: "adhoc users". Prompts are fine but don't exist unless the OBIEE developer creates them in advance, typically in a dashboard. I am talking about ad-hoc here so you know that's Answers. Try to restrict Answers users and force them to put a filter on a column and you will know what I mean. BO can do this in the metadata very easily. OBIEE can't. Prompts are fine (*) but they need to be created in advance by the report developer. (*) Actually they are not that fine, you can't even force them OOTB to use a prompt or not run a dashboard without any values. Sure there are work arounds, but such a basic feature should be part of the product!
4) OBIEE has different concepts of dims hierarchies and visual presentations. Here you are mixing them together. Indeed OBIEE 10g has such a restriction on GUI to have maximum two embedded levels. But it is only visual presentation. In business model you can have N levels of hierarchy and multiple hierarchies in dim . My goodness !!!Do you really think that ORACLE does not follow dimensional modeling ABCs? BTW please check Gartner's magic quadrants. ............BTW did you see OBIEE 11g demo ??????Yes it's only visual presentation, but that's one of the most important things! It's a stupid restriction. If you can have N levels on the BMM why shouldn't you have the ability to prent the data in more levels. Yes, I have seen the magic quadrant and Microsoft is on top of OBIEE (see http://www.gartner.com/technology/media-products/reprints/microsoft/vol2/article15/article15.html). Yes I have seen OBIEE 11g and have running on one of our Dev boxes. It's one of the most buggy releases I have seen in years. Only last week the client tools were released for Windows. How can you have proper ecosystem without proper client tools? No Solaris or HPUX release so it's a partial release. No support for other J2EE web app servers. From our point of view OBIEE 11g is a beta release. We are seating and waiting for Oracle to clean it this mess and get the product stable. And if you think Oracle Support will help read this: http://searchoracle.techtarget.com/news/2240031826/Has-the-phrase-Oracle-Support-become-an-oxymoron
5) Inheritance...Hm, maybe it is simple dimensional modeling concept of supertype/subtype described in any BI/DW books? I am not arguing. maybe BO does it with one click. yeah, convenient enough, but no critical.Consider this problem. You have a large DWH that a large organisation wants to share with different departments which they would then extend adding they own data sources and customise to their own needs. How would you handle changes in the "core" model that need to feed to the different departments metadata stores? RPD merging and MUDE is a mess to be honest, it barely works and it's too prone to human error. Once you worked in a very large project with many OBIEE developers working in different parallel projects you will realise that inheritance is the only sensible solution. I wish Oracle would see this as well. If the metadata was in a database it would have been so much easier...
6) Again just lack of knowledge of dimensional modeling in OBIEE. The one support ALL types of models: snowflakes (3NF) and star. Only what OBIEE requires you cannot have standalone logical table without any relations to at least one another table. Heh...I cannot recall such an example even from Bill Inmon. Regarding 3 layers. This gives you tremendous advantage over BO )) Why? It is long story))You can support all models in dimensional, but should you be forced to use it? 3 layers is not advantage. It's an interesting aproach to solve how you need to model things in OBIEE. You have become too used to it and now think it's the best in the world. It's not, in a relational reporting solution 2 layers are more than enough (physical with all your joins and presentation with all your business names and hierarchies).
8) You I understood you correctly ))))))) None of BI tools today can beat OBIEE on number of supported data sources. I'm just wondering. When you add new column in dim/fact table you DO NOT change your metadata????? My assumption is that BO does always "select * from <table name>"? Yes, then you don't have to change your metadata. The what kind of query BO generates against database??? select d1.*,f1* from dim d1, fact f1...????OK consider this requirement. You work for a top US bank. You have invested $5m in the state-of-the-art DWH with OBIEE that covers every requirement you may even need. The US FED comes in and tells you that it wants one of your excellent reports but filtered for a number of companies. They give the user a spreadsheet with 20k companies that you need to filter you report on. Can any user in OBIEE perform the filtering without any changes in OBIEE? No. In BO you can. End of the argument.
9) That is not true AT ALLYou saying that OBIEE can "merge" two Answers reports and get attributes from both queries in an INNER/OUTER/FULL OUTER fashion? Please show me how, I love to learn from you! (BO indeed can).
10) You r kidding me )) have you forgotten in what time are we living??))) Do you read latest news? By 2016 most of businesses will be in social networks. Everyone wants to be power user holding mobile device in his hands!!!
AND.....OBIEE already DOES it !!!The web client works for 90% of the user population, as said in my comment for real "power users" a fat client approach works best. There browsers are still not powerful enough to handle large data sets. Going back to Gartner's 2011 Quadrant for Business Intelligence Platforms, which you seem to love, I quote from it: "[...] it (Oracle) has lacked innovation around mobile, in-memory, consumerization, interactive visualization and search [...]".
Please forgive me to be so sarcastic. But today the only real advantage BO over OBIEE is PRICE. I would really advise you to look at OBIEE11g. It is almost different product then OBIEE10g.I love sarcasm. Sarcasm is my middle name. But you need to open your mind a bit. OBIEE has taken control of your brain! :-) One solution does not fit all. The world of IT is too big for that...

Business Partner in Organizational Model Missing

Hi
I have added an Org Unit in Development Server and the ID and BP number is generated.
I have Transported from Dev to Quality server by using RHMOVE50 to move the org unit.
The Org unit and ID are transported successfully but the BP number is missing.
Note: Earlier for all other Org Units in Qulaity the BP Number exist.
Please prove me solution and points will be rewared.
Thanks and Regards

Data Model best Practices for Large Data Models

We are currently rolling out Hyperion IR 11.1.x and are trying to establish best practces for BQYs and how to display these models to our end users.
So far, we have created an OCE file that limits the selectable tables to only those that are within the model.
Then, we created a BQY that brings in the tables to a data model, created metatopics for the main tables and integrated the descriptions via lookups in the meta topics.
This seems to be ok, however, anytime I try to add items to a query, as soon as i add columns from different tables, the app freezes up, hogs a bunch of memory and then closes itself.
Obviously, this isnt' acceptable to be given to our end users like this, so i'm asking for suggestions.
Are there settings I can change to get around this memory sucking issue? Do I need to use a smaller model?
and in general, how are you all deploying this tool to your users? Our users are accustomed to a pre built data model so they can just click and add the fields they want and hit submit. How do I get close to that ideal with this tool?
thanks for any help/advice.

I answered my own question. in the case of the large data model, the tool by default was attempting to calculate every possible join path to get from Table A to Table B (even though there is a direct join between them).
in the data model options, I changed the join setting to use the join path with the least number of topics. This skipped the extraneous steps and allowed me to proceed as normal.
hope this helps anyone else who may bump into this issue.

BP number in Organization model

Hi experts
When we will creating new organization structure along with Org Id BP # will be coming automatically
I would like to know what are the settings need to be done for this.
becoz now when i am creating in my production server now it is not displaying BP # for newly created Org model
Many thanks

Question on Tabular Model 2012

Hi,
I need to hide certain columns for a user group but the same columns should be visible for another user group in the same model. The out of the box 'row level security' would not work for this requirement. I tried a modelling technique, by bringing
the 'hidden fields' to a table using the 'Blank' DAX function in a 'role' on the table that contains the hidden fields, but this hides all tables related to the table that contains the hidden fields.
As a last resort I am creating two models (1) model one with all fields visible (2) model two will hide certain fields. Basically model 2 is a copy of model 1, only certain fields in model 2 will be hidden.
To avoid reading the source data twice I am planning to update the model 1 and then synchronize model 1 with model 2 ( the one with hidden fields). My gut feeling is that if I synchronize model 1 with model 2, all the hidden fields in model 2
will become visible, as the metadata in model 2 will be updated with metadata of model 1.
As the number of users would be in hundreds, implementing a complex security layer might impact the performance if we try and implement such security on the same model.
It would be great if anybody can share thoughts on the probable solution and if the approach to 'synchonize' both the models would work.
Thanks

Hi Bidyut,
According to your description, you want to implement dynamic security for two group users, right? In SQL Server Analysis Services Tabular model, we can implement dynamic security using an external security table but we can integrate this security table into
the existing tables based on particular source data at production implementations. So in your scenario, you can store the users' information on an external table, and then implement the security through this table. Here is a blog which describes how to implement
it step by step, please see:
SSAS – Tabular Dynamic Security
Hope this helps.

What approach/tools for a collages scene (to blend it all in so as not to look like a collage)

What photoshop approach/techniques/tools should I be looking into (e.g. watching tutorials) in order to create a collage scene?
That is, a scene where I superimpose various pieces of images to create it. Might be a general background (say a road), then superimposed trees from another image on the left, and a building on the right etc. So the tips/tools re how to blend them in so as to not make it look like it is a collage (well as a much as possible anyway)...

Matt Kloskowski's Compositing Secrets would be an ideal nbook for you. I beleive it was Amazon's Photoshop book of the month, or some such accolade, a while back.

Otherwise, the steps involved are Selection, Layers, and Masking. Google up Photoshop Compositing tutorials
Or a couple of general Photoshop tutorial sites wit hundreds of free videos:

http://planetphotoshop.com/category/tutorials
Also look at the Steve Caplin books, or the forum on his How to Cheat at Photoshop site.
http://www.howtocheatinphotoshop.com/
And finally try to learn about perspective, eyelines and horizons. There are two free to view videos here:

And the final finally, learn about shadows and light direction. I'd say two of the most important aspects of a believable composite are shadows and perspective.

Data modeling , creating dimention

hi ,

pls guid me urgent

Analytics Workspace Manager is the administration tool of the OLAP Server (MOLAP) from the Oracle Database.
You can build an Olap cube with it.
http://www.oracle.com/technology/obe/11gr1_db/otn_all_db11gr1.html#olap
But you can also do it with OWB. And you can do with OWB all what you need to build a datawarehouse.
Try to go through the tutorials. It's the best way to learn.
If you have problem to define measure and fact (which is a big subject), the best way is that you buy this book :
http://www.amazon.com/Data-Warehouse-Toolkit-Complete-Dimensional/dp/0471200247/ref=pd_sim_b_3
You will find on it all what you want with a clear language (It's the bible for modelling)
Good luck
