Related to Designing

Hi,
I am looking this site since from few months and am having fun with it.
Getting addicted to it and Loving it. It is informative. Thanks to all the Java community.
This time I want you guys to through some light on designing, what should be the approach to solve any problem at hand.
Now a days J2EE applications are following more and more model
driven architectures (Please correct me if i am wrong) which means the developers no need to write much code, so that they concentrate only
on business logic and all the other code is generated automatically. Many companies are building such frameworks to generate the code automatically to make development time less.
Here at this point like me developers are more and more are getting
opportunities to involve in designing part. Most of the interviewers are
also thinking that knowing a bit of UML is enough to do the designing.
But that is not the reality. Here i am confused (not only me, I guess all
who are young into development) like how to approach to solve a
problem. How to start the design for a problem after analysing?
1) Analyse
2) Identify the complexities
3) Identify the reusable components
4) Start designing the interfaces
i am not sure what might be the best way..
Please post your comments on this for the good of young developers like me.
Post your comments like, you have a problem at your hand and how you will approach to solve. (Please don't say that it depends on the
problem, i know it is, but still i believe that there should some common
things which we need to consider for any problem.)
Thank you all again.
Mahesh.

i am not sure what might be the best way..Gather requirements, find components, define responsibilities, define interfaces. Then design the components in detail.

Relational database design

i apologise in advance for the banality of this question, i
have been designing basic sites for my business for years and am
comfortable with html, and have recently designed a complex site
havig susssed .css and coldfusion code written though dw.
I CANNOT MAKE THE LEAP TO GET MY HEAD ROUND RELATIONAL
DATABASES and want to integrate some dynamic application forms
(which i can code in CF).
Can anyone point me towards a resource that will walk me
though how to build a simple (then a complex) relational database
that wont send me to sleep or make my eyes glaze over.
Its a brain block that is now causing me stress, but i just
dont get it...
SAVE ME
Ta

no worries. i can sympathize with trying to grasp new
concepts. problem is that double posting just makes it more
difficult for people to follow the thread(s).

Relations in Designer ERD

Dears,
i was creating ERD in oracle designer and i faced this issue:
i have 4 tables a,b,c,d
primary key in a is com_no which is a foreign key in b,c
so primary key in b is b_seq, com_no
and primary key in c is c_seq , com_no
both b and c primary keys are referenced from a foriegn key in d so i suppose the primary key in d
is d_seq, b_seq,c_seq, com_no
but when generating ERD i will have the primary key like this
d_seq, b_seq,c_seq, b_com_no,c_com_no
is this correct? if no how to manage?
thanks.

First of all, are you really working in the Entity/Relationship Diagrammer (ERD)? Or are you really creating database diagrams in the Design Editor? The reason I ask is that ERD doesn't create "Foreign Keys", it creates "Relationships". True, when you run the Database Design Transformer (DDT), the relationships will be transformed into foreign keys, but while you can create and designate key columns yourself, you normally don't - you let DDT create them.
Actually, what DDT wants to do, unless you set preferences to tell it not to, is create surrogate primary keys from an Oracle Sequence. Then the foreign keys are JUST foreign keys, they are NOT part of the primary key. So table A gets a primary key, A_ID, which is generated from A_SEQ. B gets a primary key, B_ID, and a foreign key, A_ID. C gets a primary key C_ID, and a foreign key, A_ID.
Now you are saying that D has a relationship to BOTH B and C. This is why it is good to use the ERD and define entities, attributes and relationships, and not jump directly to design tables, columns and foreign keys. Exactly what is the relationship between D and B, and D and C? And how does D relate to A? ERD would let you name your relationships and more clearly define them, and ask if this correctly describes the data your system must collect.
For instance, I get the feeling that D is an intersection table, and that it is defining a many to many relationship between different rows in A, via their related rows in B and C. In this case, D will have its own primary key, D_ID, and foreign keys to B, B_ID, and to C, C_ID. Notice that with this arrangement, you don't need any instances of A_ID in the D table. You can get to the right two rows of A through the foreign keys in B and C.

Searching for a good relational database design tool

Hi!
I am designing an oracle database for our plant, and I want to use a entity-relationship diagram tool to create it.
I want to design the data diagram with it, and generate creation code and run it to create the DB on our oracle server.
I would appreciate that someone suggest good quality tools that can be used to do entity-relationship diagrams and implement the db not only on oracle, but to SQL server as well, as future designs for other projects may be implemented in SQL server.
A small list of quality tools with their noteworthy features would be greatly appreciated.
Best wishes to all!

For Oracle database, Oracle Designer is the best.
If you want to be able to use it for various databases you might think of:
- ERwin
- Embarcadero ER Studio
- Sybase power designer

Is there going to be relative CSS-Designs

The new feature "content" with the new textfields, where the Text is updated on all Layouts (Desktop, Tablet, Phone) is incredibly awesome!
But I am missing on more feature, which would make work a lot easier and faster for layout desgin.
For now, I have to redesign each layout by hand.
Lets say, I have a "NEWS"- Page for example and one textfield with the same content on each layout. There are differen stlyes in one textbox:
- Heading
- Text
Each style is defined by its own.
Now, there should be a way, where I can define individual styles for each layout. Lets say in my phone layout I want the heading to be a little bigger and have a different color, I can adjust the style and say, for phone you shoud have xy settings and for tablet these.
In that way I could create a new text-box, or update a existing text box, with the new content feature, style it (in just one layout) and muse automatically styles the relative styles, because it knows, if you use this style in desktop, use these settings in mobile or tablet.
So I don't have to update all styles manually.
It would be great, if there is coming something like that!
Best regards,
Markus

Thanks for the suggestion , currently we need to do this manually by creating style and applying to created content frame. This would be feature request where the style is applied automatically selecting the content.
Thanks,
Sanjit

Design problem

Hi all,

Design questions - beginner

Hello,
I'm just getting started with BDB XML and the resources here have been very helpful. To play around with it, I imported 100,000 records from my relational db into BDB XML. I imported it as one document that sort of looks like this:
<people>
<person><name>John></name><age>22</age></person>
<person>..</person>
...100k times
</people>
Querying this database using dbxml.exe has been extremely slow, even after using indexes. So, I have the following questions:
1. Should I import it has a single document containing 100k children, or is it better to import it as 100k different documents?
2. Are there any resources available for best practices in designing the XML database, especially from the PoV of a relational database designer?
Thanks
Amit

Amit,
Using the correct indexes and release 2.3.10 your performance should be reasonably good even with a single, large document. In general, it can be better to use individual documents, especially if you want to add/remove them individually. If there is no need to keep them as one document, I'd recommend using separate documents.
Also, if you want better answers on tuning queries, you need to provide more information, such as the indexes you've declared and the queries you are using.

George

Remove hidden relation

HI Gentlemen,
I set up an ER diagram with a many-to-many relation. Designer created a mapping table automatically. Then I removed the relation and set up my mapping table manually under a different name, which I now enhanced with several new attributes. The many ends of the two new relations were mandatory, with the relations in the primary key, as usual. Now when I generated the diagram, it delivered both the old mapping table and my new one. Since then, whatever I do, the old many-to-many relation does not show up any longer; however, the old mapping table always generates. Question: How can I remove the old relation from the Repository?
Thank you very much,
Miklos HERBOLY

It is just a tip, maybe it will help you: try to remove old relations from Wastebasket in a RON.

What features does help? Which one should stay away from?
Thanks in advance.

Designer 8.0 Form compatibility with Reader 6.0 - error message

I created a form in Designer 8.0. I saved it to be compatible with 7.0, but for the most part need for it to be compatible with Reader 6.0, which is not an available option. This form actually works fine in Adobe Reader 6.0 but whenever a user initially opens the form, a message pops up advising the user that all features may not work and recommending that the user upgrade. Clicking on OK then produces a new message advising the user that they must upgrade and providing the link. Notwithstanding that message, if the user clicks Cancel the form opens and can be used as intended, with a few nonfunctioning features (like the Print button on the form). Most of the intended users are running Adobe Reader 6.0, so any help on preventing one or both of messages would be very much appreciated. (Note: This same issue was posted on March 2, 2006 related to Designer 7.0, but no answer was supplied. Im hoping there is an answer to this issue for Designer 8.0).
