Hi,
Can somebody suggest how to satrt the Object Oriented Analysis And Design. Is there any suitable site for this?
Thanks,
Subodh.
SCJP 1.4, SCWCD 1.4, SCBCD 1.3.

Many thanks Leelavati for your response.
chariflakchiri , I think you interpreted in a different way.Can you visit
http://www.objectdiscovery.com/programming/java/ooad/outline.html.
Then you will come to know what is required for you to say that you know OOAD. See what percentage of the tutorial you really need to get SCJP, SCWCD, SCBCD.

Toools to Analysis and Design in ABAP Objects

Hi All?
   Somebody knows about an "Analysis and Design Tools" from SAP? I need choice an tools to documentation class in ABAP Objects. Or, is there other like free tools for JAVA?
   Is there an Analysis and Design Model recomended from SAP?
   Thanks.

Hi Fabio,
SAP Recommends the use of UML (Unified Modeling Language). They worked with Rational Software in order to provide an external modeling tool to supports SAP's class.

How to use SOA Suite in conjunction with SOA Analysis and Design Tools

Hi everybody,
I am a novice in this field and I need some help regarding integrating analysis and design tools with SOA Suite.
We used to analyze and design with Oracle Designer and use its powerful form generator to develop a system. It almost covered all the software lifecycle and kept the traceability between anlaysis,design and implementation.
I have studied about the SOA concepts and read some papaer about SOA Suite. I have also installed the SOA demo based on SOA Suite and I found it absolutely amazing, but my problem is that It seems oracle does not have any tools for SOA Analysis and Design. am I right? if so, How can we analyze and design a system based on SOA concepts and implement it using soa suite in such a way that keeps traceability? What tools is used for this purpose?
It seems that IBM have some tools like Rational Software Architect and Rational Suite which enable people to design and analyze based on SOA concepts and then generates some pieces of code (like oracle designer in old days) but is it possible to design in these tools and then generating codes for SOA Suite ? (for example generating a bpel file from a design model)
As I told before I am a novice in this field and I would be so grateful if other users can share their expriences regarding this matter.
Any help would be highly appreciated.
Thanks in advance,
Navid

Business Process Analysis and Design

hellow fellows
Please can u explain to me briefly what's involved in Business Process Analysis & Design
Thanks
Rasham

Hello Rasham,
Business process analysis and design is a part of implementation / upgrade project. As name suggests it will analys client's business process to make the standard process across the group of company and make it most optimized to get maximum ERP support.
Some time it will cover under blueprint phase and some time it can be carried out as a saperate process before actual start of implementation.
The following link will give you detailed information about all phases of the project including Business Process Analysis and Design.

Learning systems analysis and design

hi folks ,
i am a developer , but i do not know anything about systems analysis and design
and i wanna know about it because i want to develop applications on my own
so , i need to learn systems analysis , to begin developing the application
is not there any free reference i can learn from , is not there a documentation for that ?
could you help me please ?
thanks in advance

Hi
Systems Analysis is a big subject. I can remember doing a 6 week full time course, back in the 80s. However, as a starting point, just google 'Systems Analysis' and take a look at sites such as:
http://www.comp.glam.ac.uk/pages/staff/tdhutchings/chapter2.html
In addition, the help within Oracle Designer is not bad, even if it is from an Oracle slant.
Good luck

Object Oriented Patterns and Visio

Visio question:
Does anyone know if there are established shapes for each (or any) of the object oriented patterns? If not, is anyone working on that or interested in that?
Since they all have names (Momento, Proxy, Iterator, Mediator, Observer, etc.) it seems like they ought to each have their own shape. Since Object Oriented is all about communication of intent, each pattern having its own recognizable shape would go a long way toward a more meaningful communication through diagram. Also, if they each had their own shape, then the super-patterns (based on commonly grouped patterns and interactions) could also be easily represented.
Blaine

I'm kind of making an assumption here and if it's in error then feel free to disregard the rest of this post.
Assumption that you're thinking terms of shapes for representing in UML the various patterns. Everything you need is right there in front of you already regardless of whether you use Visio, Rational, Poseidon or some other UML tool.
Patterns are not individual constructs. One does not make a Mediator class. One makes a Java class that is an implementation of the Mediator pattern. As such you would see in the static class diagram the same grouping of classes for an X Mediator as you would for Y Mediator. That is the image you're looking for. It's not a single widget that you drag onto the screen, it's in the pattern itself.
If, however, you're talking about something like a graphical representation to give to managers that says "Here be Momento patterns", then I would postulate that you're trying to communicate information that they don't need nor should they concern themselves with. Patterns are an implementation issue. They deal with, "How" we will solve a problem, not what problem will we solve. Mangaers, IMNSHO, need only concern themselves with what problems we will solve, not how they will be solved.
Just my 2 krupplenicks on the subject, your milage may of course vary.

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 ..

Compare two XML files: Analysis and Design

Hi, Java/XML/JDOM experts,
I realised that an open source of Java utility to compare two XML is still missing. So I would like to write one for my JDOM excises.
I plan to do it in three steps:
1.Define the problem domain.
2.Design the classes to be developed.
3.Coding
Below is the problem domain. Would you review it and tell me if it is fine?
Best regards,
AG
Compare two XML files
Schema assumption:
The xml files used for the comparison must have the same schema.
Definition:
1. Two elements of simple type are said equal if their name and value are identical.
2. Two elements of complex type are said comparable if their name, attributes are identical.
3. Two elements of complex type are said equal if they are comparable and their children elements are identical.

Hi,
Thanks for reviewing my idea.
The xml files used for the comparison must have the
same schema.Including not having a schema at all? And if they do
have a schema, must they be valid according to the
schema?I will only support schema based xml files. To include a schema is a good practice. So I will valid them agaisnt schema (is this possible with JDOM? I am testing ...)
>
2. Two elements of complex type are said comparableif
their name, attributes are identical.
3. Two elements of complex type are said equal ifthey
are comparable and their children elements are
identical.Do you plan to require child elements to appear in the
same order for the two documents to be equal? (Note
that XML specifically says that the order of
attributes is not significant.)No. The order is not significant as I use the attributes as the keys to find comparable element counterpart.
Here is the sample code already tested. Any comments are welcome!
The next step is to define the "delta xml schema" that will guide me to store the comparasion results. Do you have any suggestions?
Regards.
AG
public static boolean comparable(Element element1, Element element2)

Anyone recommends a good book for object oriented programming

I am a college student in computer engineering (Software) and have been programming using Java for over a year. I have become really interested in the design of softwares and the "beauty" of object oriented programming, and thus would like to advance my knowledge about the topic (my university offers an advanced oop class but I would have to wait another 6 months to take it). So my question is, could you recommend me any book that covers the subject of object oriented programming extensively? (I have learned most of the oop I know from "An Introduction to Programming and Object Oriented Design Using Java" by Nino and Hosch.
Thanks in advance

Some years ago I remember cutting my teeth on OOP using an excellent book by Grady Booch. If it's still in print and has been updated, it may be worth a look. Again it was decent. Also consider picking up a book on design patterns. Good luck.
Edit: I found it, it's called "Object-Oriented Analysis and Design with Applications", and it's in its third edition. You can find it here on Amazon.

What are object oriented methods?

i dont seem to understand the term object oriented methods. i know that it is a technology which encompasses a body of methods,processes, and tools used to construct software systems from obejcts. i know that i provides a unifying paradigm for the three traditional phases of software development: analysis,design and implementation. so how do i get more information on this. i mean this is very limited information i have on my hands. how do i explain in detail about the major features of object oriented methods and their major benefits. is there a place where i can find out about it? please help me out?

Object-oriented APEX. Best practices.

Hello,
in my company we are developing quite big application in Apex. At the beginning we saw Apex as a very developer friendly application, but now we have problem with it.
Our application has about 100 pages, most of them are not only reports but are also designed to edit and add new data. We are often using javascript and plsql procedures to handle collections and error processing. There are a lot of elements that are identical on several pages – not only processes, but also buttons, branches etc. – and when something changes, we must do the same operation on every page. Do you know any way to deal with it in better way?
Are there any “best practices” for APEX to make it more object-oriented? I know I can put e.g. plsql procedures as a function in database, but what about button functions etc.? Maybe I should name most important buttons in the same way and handle them using javascript?
Regards,
Przemek Staniszewski

Hi Przemek,
I'm not an object oriented expert so I probably can't offer you too much in the way of advice here, I'm old school from relational theory, 3GL etc. But one of the things to remember is that Apex isn't one single language like Java where it is easier to maintain good object oriented practicies and even enforces and encourages. Apex is a collection of technologies such as Relational Design, SQL, PL/SQL, HTML and Javascript which are all held together by a declarative programming interface.
Although all these technologies have varying degrees of object orientism, they are all quite distinct technologies which work together well but don't really help each other in maintaining or enforcing OO good practices. I think it would be hard to reverse engineer an existing application, but with some thought, kowledge and advice from the right areas you should be able to put together some good design and coding standards which will serve you well going forward.
There are some documents and threads you should be able to find which will also help you, but also remember you are also dealing with some long established technologies such as Relation Database Design and SQL. Too often developers with skills in more recent languages get lost in the API front end and assume the database isn't really part of the application. You know, DBA stuff. For my money the database is the centre and the most important part of the application.
My two cents worth anyway.

Object Oriented? Or Not?

Perhaps the way I raised this question would be peculiar for you as I'm a newbie!
I'm willing to use oracle object oriented programing for my applications, and some senior people(work in my organization) told me that Object oriented database concept is failed in the industry. As a reason they say that; even if Object oriented databases solved some problems people had with relational databases, still Object oriented databases are failed to facilitate most of the advantages of relational databases. It's somewhat chaotic for me, as I'm new to PL developments.
They didn't mention any specific reason; but just told me that relational databases perform well and faster than object oriented databases, and for business logic, object oriented databases has some accuracy issues.
But I'm not ready to accept that it will be useless to learn 'Oracle Object Oriented Programing' or 'Object Oriented Database Concept' would be failed.
So I need to know,
1. Will it be useless to learn & use 'OOP' techniques when learning PL/SQL programing?
2. Is there any disadvantage of using 'OOP' with oracle? (If there is any, please let me know if you have time for that).
Especially, (The most pleasing answer I would like to hear from you ;-) )
3. If Object Oriented Databases concept is better and something that a "PL/SQL" developer must learn; please let me know that.
Please provide me a link if you can, which would help me to learn why should we use 'OOP' with oracle (if Object oriented database is better than Relational database)

Intruder wrote:
So I need to know,
1. Will it be useless to learn & use 'OOP' techniques when learning PL/SQL programing?No. OOP has very little do with relational database design. The two is not mutually exclusive and can co-exist easily.
2. Is there any disadvantage of using 'OOP' with oracle? (If there is any, please let me know if you have time for that).That depends on how+ you use it. If OOP was truly horrible and bad, then why does Oracle spend money on the research and development on it for their RDBMS product?
Especially, (The most pleasing answer I would like to hear from you ;-) )
3. If Object Oriented Databases concept is better and something that a "PL/SQL" developer must learn; please let me know that.OOP is not Object Orientated Database. These are two very different concepts. OOP competes with procedural programming. Object Orientated Database design competes with Relational Database Design (and others of course).
There are two primary issues with an Object Orientated Database design. Complexity. Performance.
Do you for example store the subclasses of the same abstract class in the same physical object table? You can do that in Oracle.. but then the database need to resolve the class type at run-time.. every single time.. for every single object accessed... At what cost ito performance?
How do you treat collection classes? A collection can be stored as a physical table. It can also be stored as an attribute (column) of an object (table) - in which case the physical implementation for that is a nested table. There are dire performance issues with nested tables when these are used and applied incorrectly.
There are numerous such issues.
Compare this with something as mature and robust as Relational Database Design. Easy to understand. Easy to use. And what the Oracle RDBMS product was specifically designed to support.
Which one is "+better+" (especially in the Oracle RDBMS environment)? It should be obvious.
I suggest that you read Codd's original paper on "+A Relation Model of Data for Large Shared Data Banks+", read "+The Third Manifesto+" from Chris Date, and papers from various other authors for insight.

Trying to understand object oriented programming

Hi all,
I'm new to programming and I'm trying to learn C and Objective-C to eventually write an iPhone/iPad app.
I want to make sure I'm understanding some fundamental Object Oriented principles and so I'm starting with a very basic program.
I've produced a class called CartesianPoint which has an x and y variable plus methods to set and return these variables and also a method to calculate the magnitude from the origin.
What I would like to do now is to extend the program to have a CartesianVector class.
I'm a little unsure as to whether a Vector is a subclass of a Point or whether a Point is a subclass of a Vector... or neither?
Secondly, I'm a little unsure of how to implement the vector class to use two point objects. How should the header and implementation files be set up to receive point objects from the main.m program?
I'd like to also try and extend the program to include other ways of defining a vector (i.e. origin, unity vector and magnitude).... and then use the vectors to build 2D shapes.
Many thanks,
Glyn

Hi Glyn -
I agree with William and would vote for "neither". I see a subclass as a specialization of its superclass, not, for example, something contained by its superclass. A container relationship might apply to a subview and its superview, yet the class of the superview could be a specialization of the subview's class so the subview's class might be the parent of the superview's class. The classic example of cat as a subclass of animal (cat:animal) can be misleading if we see the relationship as member:group. Cat is a subclass of animal because it's a specialization.
Also ask, "What's accomplished by making a subclass"? Does the subclass want to use all or most of the parent's instance variables and methods? Could the job be done any other way? Are any of those ways simpler or do they lead to more reusable code?
One of the best examples (from the Cocoa docs?) is about a programmer who needs a specialized array. A newbie might immediately attempt a subclass of NSArray (a rather tricky subclassing job as it happens). In most cases however, the correct solution would be a class which includes an NSArray* type instance variable.
Hope some of the above is helpful!
