Design Issue- Experts Help

Hi,
I need some ideas from experts in this design issue.
I am in just the beginning of my data flow design.
I have 10 fields to be displayed on my report.
All these fields come from 4 different datasources.
What would be the ideal way to proceed.
Thanks,
JB

JB,
First analyse the data which comes from 4 ODS's. Check what are the common fields in four. Based upon that you can go for various options. More analysis will lead you choose a proper and consistent design.
If possible give the fields of four data sources.

Design Issue - Need Help

Okay so I'm having a little bit of a design issue. This is how the section is question looks in design mode:
I have temporarily published the site for now. IE and Firefox load absolutely fine with no problems at all, but when opened in chrome is looks like this:
The temporary link for the site is: CCTV Dorset, CCTV Somerset, CCTV Systems Hampshire, CCTV Security Wiltshire - RS1
As said it is working in IE and Firefox FINE but will not load correctly in chrome.
Can anyone help as to why because obviously I want this to work in all browsers.
Thanks.

Is your text inside the blue boxes? Might be how chrome makes the text flow if you just placed a formatted them behind... I would format the text box with color, border and padding to get the same effect and make it flow properly...
Do you have a separate text box for each text area?
I am guessing your issue is might be from how it was put together...
I have fixed sites that were doing this in mobile chrome with this css change ... but I am guessing you are using the desktop version..
I know this fixes similar issues in chrome for mobile
Try adding this to your site global css...
html * {max-height:1000000px;}
I know it fixes issues with the mobile version of chrome

ERD Design Issue Urgent help needed .

Hi ,
I'm designing a movie theatre system . I was drawing the ERD Diagram but I'm stuck .
One theatre can have many movies and One movie can be run on many shows .So I have created seperate Theatre and Movie tables and another associative table containing only MovieID and Theatre ID .
Now number of shows in a theatre are fixed .. Morning ,Evening and Night .
The problem comes when I want to find which movie is running on which theatre and what is the show timimg . If I create another table as show table having theatre id and showid (say 1 is Morning and so on ) then how to relate that with movie .I tried a lot but not being able to find out .
How will I design the tables so that they are in 3rd Normal form .Its a bit urgent.
Please help me out .
Regards,
Rahul .

Hi Rahul
If I were you, then to make it flexible i would have tables for
1) Theatre
2) Movie
3) Show
4) movie_show_theatre_mapping
And according to your design it should be
1) Theatre
2) Movie
3) Show table with foreign key to theatre
4) Show_movie_mapping
Here you can find the movie timing at a particular theatre by quering
show_movie_mapping and show table where theatre id is a foreign key in show table.

J2EE Design Issue (Experts only)

I have two entities Group and User. They have many-to-many relationship. When we see with respect to database. The relation will have another table say GroupUsers.
What about EJB2.0 relationships. Do I need to have new table. If yes then what is the purpose of Collection in both entities, like Group has Collection of users and user have Collection of Groups because of many-to-many relationship.
And if I dont need another table where will the relation be persisted?
Thanx in advance

Hi,
There are 2 ways u can implement many-to-many relationships
(1) Using a True many-to=many relation, meaning Group will have a collection of Users and User will have a collection of users.
(2) Use a third table to depict the relation that user and group are having. If you implement this you will have a table called UserGroups, where User and Group will be linked in one record.
There are stregnths and weaknesses of each of these implementations. Basically, you can put it like this.
If you are only storing the information about the relation and you dont need to do alot then its always advisable to use a third table to represent the relation.

Data mart from two DSOs to one - Loosing values - Design issue

Dear BW experts,
I´m dealing with a design issue for which I would really appreciate any help and suggestions.
I will be as briefly as possible, and explain further based on the doubts , questions I received in order to make it easier go through this problem.
I have two standard DSOs (DSO #1 and #2) feeding a third DSO (DSO #3), also standard.
Each transformation DOES NOT include all fields, but only some of them.
One of the source DSO (let´s call it DSO #1) is uploaded with a datasource that allows reverse type of records (Record Mode = 'R'). Therefore some updates on DSO #1 comes with one entry with record mode 'R' and a 2nd entry with record mode = 'N' (new).
Both feeds are delta mode, and not the same entries are updated through each of them, but the entries that are updated can differ (means an specific entry (unique key values) could be update by one of the feeds, but no updates on the 2nd feed for that entry).
Issue we have: When a 'R' and 'N' entries happen in DSO #1 for any entry, that entry is also reversed and re created in the target DSO #3 (even being that not ALL fields are mapped in the transformation), and thefore we loose ALL the values that are exclusively updated through DSO #2, becoming blank.
I don´t know it we are missing something in our design, or how should we fix this issue we have.
Hope I was more or less clear with the description.
´d really appreciatted your feedback.
Thanks!!
Gustavo

Hi Gustavo
Two things I need to know.
1. Do you have any End Routine in your DSO? If yes, what is the setting under "Update behavior of End Routine Display"....Option available right side of Delete Button ater End Rouine.
2. Did you try with Full Load from DSO1 and DSO2 to DSO3? Do you face the same problem?

Design issue with the multiprovider

Design issue with the multiprovider :
I have the following problem when using my multiprovider.
The data flow is like this. I have the info-objects IobjectA, IobjectB, IobjectCin my Cube.(Source for this data is s-systemA)
And from another s-system I am also loading the masterdata for IobjectA
Now I have created the multiprovider based on the cube and IobjectA.
However, surprisingly join in not workign in multiprovider correctly.
Scenario :
Record from the Cube.
IObjectA= 1AAA
IObjectB = 2BBB
IObjectC = 3CCC
Records from IobjectA =1AAA.
I expect the record should be like this :
IObjectA : IObjectB: IObjectC
1AAA       :2BBB       :3CCC
However, I am getting the record like this:
IObjectA : IObjectB: IObjectC
1AAA       :2BBB       :3CCC
1AAA         : #             :#
In the Identification section I have selected both the entries for IobjectA still I am getting this error.
My BW Version is 3.0B and the SP is 31.
Thanks in advance for your suggestion.

May be I was not clear enough in my first explanation, Let me try again to explain my scenario:
My Expectation from Multi Provider is :
IObjectA
1AAA
(From InfoObject)
Union
IObjectA     IObjectB     IObjectC
1AAA     2BBB     3CCC
(From Cube)
The record in the multiprovider should be :
IObjectA     IObjectB     IObjectC
1AAA     2BBB     3CCC
Because, this is what the Union says .. and the Definition of the multiprovider also says the same thing :
http://help.sap.com/saphelp_bw30b/helpdata/EN/ad/6b023b6069d22ee10000000a11402f/frameset.htm
Do you still think this is how the behaviour of the multiprovider.. if that is the case what would be the purpose of having an infoobject in the multiprovider.
Thank you very much in advance for your responses.
Best Regards.,
Praveen.

A web service design issue with patterns

Hello,
I�d like to ask for your help in the following design issue:
I need to create an email sending web service (with Axis). Only just one method which returns with an integer return code. This handles the following:
- based on the given parameters gets the email addresses from an
LDAP server (with netscape ldap for java)
-     makes a cache from them (only after a timeout period will be the cache
refreshed) (don�t know what tool to use for this)
-     selects html templates which to be sent based on the given parameters
-     sends emails with the appropriate templates (with Velocity)
-     the whole process is logged (with log4j)
I have to write the code as generic as possible. I know that some design pattern should be used for this. (some from GoF , and I know there exists design patterns specially created for web services as well).
Could you enumerate me which patterns (and for what part of the program) would be the best choice to solve this problem? I have read through some books about patterns, but don�t have the knowledge to pick up the right one for a concrete problem like this..
Thank you in advance,
nagybaly

Hello,
I�d like to ask for your help in the following design
issue:
I need to create an email sending web service (with
Axis). Only just one method which returns with an
integer return code. This handles the following:Lots of responsibilities here. You would do well to break this up into several classes that you can test separately.
I would also advise that you not embed all this in a servlet. Make a service that collaborates with several objects to accomplish the task and let the serlvet just call it.
.> - based on the given parameters gets the email
addresses from an
LDAP server (with netscape ldap for java)I'd recommend Spring's LDAP module. Pretty terrific stuff.
cache from them (only after a timeout period will be
the cache
refreshed) (don�t know what tool to use for
this)Maybe EhCache or OsCache or something like that.
-     selects html templates which to be sent based on
the given parametersWhere does this come from? Certainly not the LDAP. A relational database? Write a DAO for the document template.
-     sends emails with the appropriate templates (with
Velocity)Have an e-mail sender service using Java Mail.
-     the whole process is logged (with log4j)Easily done.
I have to write the code as generic as possible. I
know that some design pattern should be used for
this. No pattern. There might be patterns, if you say that the DAOs to access the LDAP and RDB are patterns.
Stop thinking patterns and start thinking objects.
(some from GoF , and I know there exists design
patterns specially created for web services as
well).Nope.
Could you enumerate me which patterns (and for what
part of the program) would be the best choice to
solve this problem? I have read through some books
about patterns, but don�t have the knowledge to pick
up the right one for a concrete problem like this..
Thank you in advance,
nagybalyYou haven't read them because they aren't there. Your problem is pretty specific, even if it's common.

Need some expert help on this one

My PPC 10.4.11 mac is running very very slow with plenty of disk space and when I try to verify permission, repair permissions etc. disk utility freezes up to the point where I have to cold shut off the computer. Issues started yesterday when a page in iweb became corrupt causing me to have to completely redesign my index page and then it started freezing up. Do I just need it do an achieve and install or is there something else I can do?

As your very expert help already mentioned, You must repair the HD.
If Disk Utility cannot do it then your best bets are DiskWarrior from Alsoft...

But you need the CD, the download won't work unless you have another Bootable HD.

SOA Design issues and other politics

Hi all,
I have a requirement for live data feed from external system. I am using SOA11g and JDeveloper 11g. There are two designs, one proposed and other I have in mind to achieve this.
1) The external system sends XML data in a push model to the exposed SOA Web Service (uses one-way messaging mode) at my end. I then store the message in the database
a) In this design how do we keep track of all messages that are sent are received. Is there a better solution.
2) The third party is proposing a Web Service at their end. The application being real-time (i.e any changes at their DB end i.e some DB tables, should be propogated across to our web services using XML messages). I will have to keep sending XML requests on a regular basis (say every 5 seconds). Can I achieve such type of Web Service client using SOA 11g?
a) Here I have a design issue, that the data feed is live, why do the WS client have to keep sending requests at regular intervals. Why can't the third party send data whenever there is an update/insert at their database end. Third party is coming up with advantages like loose coupling and making the Web Service more generic. I doubt all the claims give that the applications are B2B and we are the other ones who will be using their web services for the time being. Their may be other two organizations later on.
b) If the first request is not yet returned, will the second request after 5 seconds be blocked.
This designs and solutions are becoming quite political across organizations, and got to do with who will take the blame for data issues. I just want a proper SOA design for live data feed. Please suggest the advantages and disadvantages of both if anybody has been through this path.
Thanks

Design Issue: Localization using Lookup OR Dependency Injection

Hello Forums!
I'm having a design issue regarding localization in my application. I'm using Spring Framework (www.springframework.org) as an
application container, which provides DI (dependency injection) - but the issue is not Spring- but rather design related. All localization
logic is encapsulated in a separate class ("I18nManager"), which basically is just a wrapper around multiple Java ResourceBundles.
Right now localization is performed in the "traditional" look-up style, e.g.
ApplicationContext.getMessage("some.message.key");
where ApplicationContext is a wrapper around the Spring application context and getMessage(...) is a static method on that
context. The advantage of that solution is a clean & simple interface design, localization merely becomes a feature of classes, but
is not part of their public API. The only problem with that approach is the very tight coupling of Classes to the ApplicationContext, which
really is a problem when you want to use code outside of an application context. The importance of this problem increases if one considers
that I18N is a concern that can be found in every application layer, from GUI to business to data tier, all those components suddenly depdend
on an application context being present.
My proposed solution to this problem is a "Localizable" interface, which may provide mutators for an "I18NManager" instance that can be
passed in. But is this really a well-designed solution, as almost any object in an application may be required to implement this interface?
I'm too concerned about performance: the look-up solution does not need to pass references to localizable objects, whereas my proposed solution
will require 1 I18NManager reference per localizable object, which might cause troubles if you let's say load 10.000 POJOs from some database that
are all localizable.
So (finally) my question: how do you handle such design issues? Are there any other solutions out there that I'm not aware of yet? Comments/Help welcome!

I agree that overly tight coupling can be a problem, but sometimes a dependency just can't be helped. They aren't all bad. The only class with no dependencies calls no one and is called by no one. We'd call that a big, fat main class. What good is that?
Personally, I would discourage you from wrapping Spring too much. I doubt that you're improving your life. Better to use Spring straight, the way it was intended. I find that they're much better designers than I am.
My proposed solution to this problem is a "Localizable" interface, which may provide mutators for an "I18NManager" instance that can be

So (finally) my question: how do you handle such design issues? Are there any other solutions out there that I'm not aware of yet? Comments/Help welcome!I would use the features that are built into Spring and Java until I ran into a problem. It seems to me that you're wrapping your way into a problem and making things more complex than they need to be.

Security design issue

Hi Folks,
I've a security design issue using J2EE architecture framework in my
project..
Proj Requirement:
i) User Logs-into a health b2b/b2c portal website...
ii) Check the user exist in the database or LDAP directory service.
iii) If exist user then check the role Patient/Insurance Provider/Physician?
iv)If Patient then display his personal health record history.
else Insurance Provider then display about Insurance Policy information,
which he can update/create insurance for entered patient id. If patient has
granted access to Insurance Provider
and if Physician then display about hospital information like
waiting patients,sending appointments,etc..
The above security access control role & policy has to be implemented
very strong. so that other user cannot view/update someone health records..
Development tool:WebLogic Server/Oracle/LDAP.. on Linux
Security Problem:
i)What is the best security solution for the above requirement?
ii)How do I authenticate/validate user using J2EE security framework?
Can anyone explain in details or steps to implement?
Thanks,
-raj-

I'm assuming that your using WLS 6, if so check out (I know we cover this in
the documentation but I'm guessing at the title) the "securing your site"
guide. Some of what you're planning the WLS server can protect through good
ACL usage. I'd recommend creating at least three groups (patient, provider,
physician), clearly the danger lies in having a user who is a member of more
than one group. I'd recommend implementing your own role checking at both
the servlet and EJB levels to fully enforce information access, using
servlet state and stateful session beans should help.

Design issue using JFrame, JPanel, JLabel

I have been working on this problems for several months now and I and nearly finished.
I have a design question I hope others from this forum can provide some incite to the best approach.
The problem space is a 8 X 8 Chessboard. I have designed a board using JPanels and JLables sitting inside a JFrame. In each square on the chessboard is a JLabel with an image. The "board" sits in the DEFAULT LAYER of a JLayeredPane. As the user clicks a specific square, a queen is placed in the square (8-queens problem). The only thing I do is swap out the image. All this works well--thanks to several of you from this forum. :-)
When I add a new queen to the board, the application goes through the evaluation of attack positions. Next, the application should display the new chessboard with only the queens not threaten by other queens. I keep up with the chessboard using an boolean array internally. I build a second boolean array for the new or refreshed chessboard.
What I want to do is build a second chessboard and "swap" it out with the one in the default layered pane. Can someone be so kind and shine some light on this design issue for me?
Thank you for taking the time to read my post.

I don't understand this approach. Swing is by default 'double buffered' and will not flicker. You will get this be default since this is one of the things the Swing painting model gives over AWT.
You should look at just using JComponent and the paintComponent() method for drawing what you need.
What I've done in the past is have a simple XML JDoM model. Have components that render themselves based on this model.
Changing the model then I just issues a call to repaint() at the top level container.
You can also add and remove items from the parent container. Then issue validate() or repaint(). Can't remember now but I think validate() hits the layout manager logic and then repaints.
I'm pretty sure the Romain guy posted an example of how to easily draw a background chess board in a panel. ;-)
The tree concept might really prove useful for a 'gaming tree' approach at the AI also.
If you look at the Java3D API you will see they use a tree to represent what is rendered and the details about it. Really nice until you change something in the tree that cause the renderer to blow up. ;-)
I guess the moral is always make small simple changes and test.
Hope this is helpful.

Route Reflectors Design issue

Hi,
I am having this design issue with route reflectors and could use some help.
I have 18 routers fully meshed in an MP-iBGP session and i am going to introduce route reflectors into the network to minimize the total number of TCP sessions
My problem is that some of these routers have outboud policies with one another. for example i have a route map on router 1 affecting only router 2 and would like to keep it this way
is there any way to do that through route reflectors ?
Thank you
Hadi

Hi Riccardo,
I have 18 routers in a full MP-iBGP mesh topology. Some pairs of these routers have the following policy :
I have a route-map matching on Route Targets and i am setting the next hop to be different from the rest of the RT for that site.
This way, the prefixes originating from site A for example will reach site B with different next hops depending on how i set it in my route-map.
These policies are only between pairs of routers i.e. router#1 needs only to affect router#2
How can i achieve this using RRs
Thank you
Hadi

Mid 2010 15" MBP i5 A1286 POWER ISSUE-PLEASE HELP-

The MBP works fine when mains connected but the only issue is every time I take the charger out it shuts down on me!!! So I have checked with a multitester & looks good the only thing i find hard to check for power is the battery itself as its hard to get a good connection, also I took to local Apple store & they checked with a new battery but said its still same issue so the guy disconnected nearly all the connecters off to check if they causing issue & he said now the battery is charging.
So they still have the laptop to do further tests etc, but I’m not sure what could be the problem hear as maybe there is some component which is bad so the battery’s not charging or what else could be the issue please help & advice as I’m really confused as if it was something to do with the logic board then surely it would not even charge even after checking with the multitester or like Apple genius done by disconnecting other components...
ANY HELP OR ADVICE WOULD BE HELPFULL,
THANKS GUYS

THANKS FOR THE HELP GUYS!!! BEEN AROUND 5 DAYS & NOT ONE PERON HAS HELPED...

I am having major issues with links in keynote! Even though the links (a navigation system) are on the master page, they are only working on some of my slides. Anyone have ideas on how to fix this or similar issues? Help!

I am having major issues with links in keynote! Even though the links (a navigation system) are on the master page, they are only working on some of my slides. Anyone have ideas on how to fix this or similar issues? Help!
I have created a navigation system on the master pages and set the presentation to links only mode. I also have other links scattered throughout the program, like a linkable table of contents, etc. Some of them work, some of them don't. Not sure why. Anyone out there having similar issues? Or have any idea on how I can solve this issue? Any help would be appreciated!
Thanks!

Links should not create any problems in Keynote. If they are set up correctly on text, the text will be underlined. Objects that have links will have a curved arrow bottom right, if you click the arrow a popup will display the link information.
Try this repair for Keynote, ensure you complete all the tasks and in the order shown:
1
delete all the iWork applications if you have them, not just Keynote, using Appcleaner from Mac Update, its a freeware application
2
empty the trash: Finder > Empty Trash
3
Shut down your Mac, wait 30 seconds, then power on the Mac, immediately after the start chime, hold down the Shift key
When you see the grey Apple symbol and progress indicator (a spinning gear), release the Shift key.
If you are prompted to log in, type your password, then hold down the Shift key again as you click Log in.
4
Let the Mac fully boot up, it will take longer as the OS is repairing the drive
5
when fully booted, go to Applications > Utilities > Disc Utility; click on the boot drive then First Aid tab and click repair disc permissions
6
when complete, restart the Mac normally, Apple menu > Restart
7
install Keynote from the Mac App Store
let us know if this helped
