Design and model

Hi
          Anyone know of a good tool for designing and modelling a website that is
          written with JSPs ?
          Thanks
          C.

To simple design and modeling , we can go for DreamWeaverMX.
if we want to go to furthur implementation for components, we can go for Eclipse ,MyEclips and SmartDrawn.

Good database design and modelling books

Hi ,
I need to work on designing a database from the scratch by creating logical database design and then physical database design.I'm new to database design.
Can someone please point me to some good database design and modelling related books /tutorials.
Regards,
Bharath.

Hi Girish Thanks for the information.
I would definitely look into this book later.
I don't mind paying any amount of money,if that book gives me the knowledge I want.
As this book is international edition,for shipping it is taking 8-10 business days and by that time I need to complete designing my database and probably I might need to some other book.
Is this a school assignment? I hope so. Referring back to your opening statement "I need to work on designing a database from the scratch by creating logical database design and then physical database design.I'm new to database design." I can only say that database design is a very big subject. If you are starting from a position of no knowledge at all, I'm afraid there is nothing that is going to give you the knowledge you need in the time frame you have. I will say you need to start by learning the rules of Data Normalization. Make your logical design Third Normal Form. Good can be your friend. There is actually a pretty good write-up on Data Normalization on Wikipedia.

Hi, I have CS6 Design and Web Premium and dont want to have a subscription model. Is there an alternative at Adobe or should I swap to Corel.

Andre,
Why not use the obvious alternative: Stay with CS6?
Many do.
That will give you at least as much compatibility with others using Adobe applications as will a switch to Corel.

Logical Database design and physical database implementation

Hi
I am an ORACLE DBA basically and we started a proactive server dashboard portal ,which basically reports all aspects of our infrastructure (Dev,QA and Prod,performance,capacity,number of servers,No of CPU,decomissioned date,OS level,Database patch level) etc..
This has to be done entirely by our DBA team as this is not externally funded project.Now i was asked to do " Logical Database design and physical Database
implementation"
Even though i know roughly what's that mean(like designing whole set of tables in star schema format) ,i have never done this before.
In my mind i have a rough set of tables that can be used but again i think there is lot of engineering involved in this area to make sure that we do it properly.
I am wondering you guys might be having some recommendations for me in the sense where to start?are there any documents online , are there any book on this topic?Are there any documents which explain this phenomena with examples ?
Also exactly what is the difference between logical database design vs physical database implementation
Thanks and Regards

Logical database design is the process of taking a business or conceptual data model (often described in the form of an Entity-Relationship Diagram) and transforming that into a logical representation of that model using the specific semantics of the database management system. In the case of an RDBMS such as Oracle, this representation would be in the form of definitions of relational tables, primary, unique and foreign key constraints and the appropriate column data types supported by the RDBMS.
Physical database implementation is the process of taking the logical database design and translating that into the actual DDL statements supported by the target RDBMS that will create the database objects in a target RDBMS database. This will generally include specific physical implementation details such as the specification of tablespaces, use of specialised indexing (bitmap, clustered etc), partitioning, compression and anything else that relates to how data will actually be physically stored inside the database.
It sounds like you already have a physical implementation? If so, you can reverse engineer this implementation into a design tool such as SQL Developer Data Modeller. This will create a logical design by examining the contents of the Oracle data dictionary. Even if you don't have an existing database, Data Modeller is a good tool to use as a starting point for logical and even conceptual/business models.
If you want to read anything about logical design, "An Introduction to Database Systems" by Date is always a good starting point. "Database Systems - A Practical Approach to Design, Implementation and Management" by Connolly & Begg is also an excellent reference.

XML Data Server and model help

All,
I have the following files
1) travel.dtd
2) travel.xml.
I've set up a XML data server with JDBC driver com.sunopsis.jdbc.driver.xml.SnpsXmlDriver and URL = jdbc:snps:xml?d=c:/XML/travel.dtd. I have created a model in designer and have successfully reversed the datastores generated from the dtd.
The travel.xml file has data populated within it, but when I right click on the datastores, there is nothing displayed. This makes sense because the xml server is configured to point at the .dtd. Do I need to change my topology connection to connect to the xml document as opposed to the dtd. Can someone tell me what i'm missing?
thanks for your help.

Since its not displaying anything as you are saying you just change the property to "f" and check.
Example
jdbc:snps:xml?f=/xml/myxml.xml&d=/xml/myxcd.xsd&s=MYSCHEMANAME
("s=MYSCHEMANAME": This schema will be selected when creating the physical schema under the XML data server.)
Hope it helps.
Thanks

OO Design and Java

I've been studying Java for a while now and am comfortable with the syntax and OO concepts. However, most of my programming experience is more traditional where you start off with an ER diagram and then develop the application to go on top of that. I have an idea for an application that I want to create using Java, but I'm having a hard time bringing the concepts of OO into a realistic design for a Java program. Can anybody out there point me to a site or resource that has an example of an OO design and what it looks like fleshed out in a Java program?
Thanks!

Entity relationship diagrams.
I associate them with database designs though.
To model in OO just try and think of everything as real world objects.
So for example if you would like to program a chessboard.
You would define a class which models the behaviour of the board which would include things like movePiece, setup board, PlayersTurn etc...
Now on that board you would have chess peieces each with thier own ability. You would have a class named abstract peiece which can not be instansiated just subclasses. Your subclass would be pawn, rock, knight etc.
Each has thier own ability. Object communicate by passing messages to one another.
Hope this helps somewhat

Control Design and Simulation and DAQ

I'm learning Control Design and Simulations. I have some questions about it.
1. For System Identification use, we can find the transfer function/model of the system by feeding data measurement from the system. But, how long data do we need to be sufficent for Identification System to estimate the model? Until the get saturated value (steady state)? or any other intervals? What if the system is unstable? How will Identification System Toolkit estimate that case?
2. For connecting to hardware, we just connect the clock in the simulation loop to the hardware? And the simulation loop will simulate the blocks inside once it got the trigger/data from the DAQ? what about the step time and solver? Do they follow the timing from hardware? or they will run on their own supplied values/clock?if we use USB DAQ, we can't have any clock from it (as far as I know it's because USB connection is not that stable for clocking since it might be any jitters or delays.) So, how do we configure the timing parameter for USB DAQ?
3. There is possibility to convert model in transfer function to state space, how do we know the states inside that conversion?
Any helps would be great...
Thanks in advance...

Dear Chin ho,
After going through your questions I found some documentation which will be useful for you. But I you still have more questions, you can reply me any time.
1- About the data and amount of it I couldn't find any info but maybe you can use the new functions in LV version 2009 and find your answer.
Estimating States of Nonlinear Stochastic State-Space Models with Extended Kalman Filters
In previous versions of the LabVIEW Control Design and Simulation Module, you can use the Discrete Kalman Filter function and the Continuous Kalman Filter function to estimate the states of a linear discrete or linear continuous stochastic state-space model, respectively. In the LabVIEW 2009 Control Design and Simulation Module, you can use the Continuous Extended Kalman Filter function and the Discrete Extended Kalman Filter function to estimate the states of a nonlinear continuous or a nonlinear discrete stochastic state-space model, respectively.
The Continuous Extended Kalman Filter function and the Discrete Extended Kalman Filter function estimate model states of a partially observable plant based on noisy measurements. First, use the SIM Discrete Nonlinear Plant Model template VI or the SIM Continuous Nonlinear Plant Model template VI, located in the labview\templates\Control and Simulation directory, to define the system model. Then use the the Discrete Nonlinear Noisy Plant function or the Continuous Nonlinear Noisy Plant function to simulate the discrete or continuous nonlinear model, respectively, with the addition of noise. Finally, use the Continuous Extended Kalman Filter function or the Discrete Extended Kalman Filter function to estimate the states of your model.
The Continuous Extended Kalman Filter function and the Discrete Extended Kalman Filter function linearize the nonlinear system either by calculating a Jacobian matrix internally or by using an external Jacobian matrix that you define. Use the SIM Continuous Jacobians template VI or the SIM Discrete Jacobians template VI, located in the labview\templates\Control and Simulation directory, to define an external Jacobian matrix.
Refer to the LabVIEW Control Design User Manual, accessible by navigating to the labview\manuals directory and opening CD_User_Manual.pdf, for more information about estimating the states of nonlinear stochastic state-space models with extended Kalman filters.
2- I think that I found a pdf document about this part of your question which will be helpful. If you would like to give your email address, I can send it to you.
3- About this part you can check the help function in LabVIEW when you open the "CD Convert Transfer function To State-space" function in your front panel.
I pasted some info about the mathematic part below.
The LabVIEW Control Design and Simulation Module provides tools to study the dynamics of systems described by linear time-invariant (LTI) continuous and discrete models. You can create deterministic state-space, transfer function, and zero-pole-gain models. You also can create stochastic state-space models and the second-order statistics noise models. You can use these forms to describe both single-input single-output (SISO) and multiple-input multiple-output (MIMO) systems.
Continuous transfer function and zero-pole-gain models use the s variable to define time, whereas discrete transfer function and zero-pole-gain models use the z variable to define time. Continuous state-space models use the t variable to define time, whereas discrete state-space models use the k variable to define time.
Deterministic State-Space Model
Continuous
x(t) = Ax("t) + Bu(t)
y(t) = Cx(t) + Du(t)
Discrete
x(k + 1) = Ax(k) + Bu(k)

Stochastic State-Space Model
Continuous
x(t) = Ax(t) + Bu(t) + Gw(t)
y(t) = Cx(t) + Du(t) + Hw(t) + v(t)
Discrete

y(k) = Cx(k) + Du(k) + Hw(k) + v(k)
Second-Order Statistics Noise Model
Q = E{w . wT} – E{w} . ET{w}
R = E{v . vT} – E{v} . ET{v}

Adobe Creative Suite 6 Design and Web Premium and Adobe CC.

Hey y'all i have a list of questions that i wanna ask about adobe. I planned to buy Adobe CS6 but not sure yet because of there is an Adobe CC now.
1. Do i need to have Adobe CS6 version first to get Adobe CC?
2. Btw what is Adobe CC? Is that only used to keep updating the adobe software or how? please explain me !
3. Do we have to pay monthly for Adobe CC?
4. How much is the cost of Adobe CS6 design and web premium?
5. If you have any suggestions please tell me so i could think about it
I'd like to hear y'all answer as soon as possible i need y'all!
Thanks y'all....>.<

1. Do i need to have Adobe CS6 version first to get Adobe CC?
no
2. Btw what is Adobe CC? Is that only used to keep updating the adobe software or how? please explain me !
it's a subscription model of leasing software. instead of buying software and owning it in perpetuity (or until it becomes obsolete), you pay a monthly or annual fee for the latest adobe software. as new versions become available, your subscription allows you to upgrade at no additional cost.
3. Do we have to pay monthly for Adobe CC?
monthly or annual
4. How much is the cost of Adobe CS6 design and web premium?
US $1,899, Creative Suite 6
5. If you have any suggestions please tell me so i could think about it
it doesn't make much sense to me to buy cs6 software. there are already two versions (cc and cc 2014) that are newer.

WebDynpro component interface and Models

Hi there,
I'd like to know how I could reuse Models and WebDynpro Interfaces from Projects to Projects.
For instance, I have created models and webdynpro interface in Appication1 in Project1. Now, I have created Project2 and Application2 and would like to re-use the components and models that I created in Application1. Is it supported in NW preview version or any production version?
Any help will be appreciated.
Thank,
Paul

DC dependencies are resolved automatically. If you build a DC which depends on another it's ensured, that the "used" DC is built before the using one. This includes every dependency to a public part entry, even model dependencies.

"File->New->Development Component Project". If this shortcut doesn't exist in your IDE version, select "New->Project" and then choose "Development Component" in the list on the left side (I hope it's there ;).
Another hint: Since you don't have the Design time repository (DTR) active in Sneak Preview, you can only work with the "LocalDevelopment" repository. This is not really a problem, since it's possible to transport the DCs to the DTR later.

Designer and BPWin

Hi all
We need to migrate all our contents from BPWin to Designer.
With the import wizard in Designer one can import text file, but Oracle recommends only to use this utility when migrating contents between two Designer repositories. In fact, the wizard fails when the input is a text file extracted from BPWin. I'm afraid this is not a issue in Designer.
I'd been thinking about directly insert the contents of the txt file in the repository tables, but this would likely result in a very hard work.
Suggestions are welcome. Please we need help
Thanks

Hi Francisco,
Unfortunately, Designer does not support the direct import,
export or migration of models from/to another modeling tool
such as BPWin.
However, you may want to look at one of our partners:
http://www.metaintegration.net
They offer bridging tools that will import/export models
between Designer and other tools using their intermediate
step know as the Meta Integration Model Bridge. You may
want to click on the Supported Tools link to see if they
support BPWin or contact them for more information.
The only other thing I can suggest is to use your finished
BPWin models to generate your designs to a database, then
capture the design of the database back into Desginer (to
create a server model), then using the Designer utilities
to retrofit this to an Entity Relationship Diagram.
Not a full workaround, but ...
Hope this helps.

Requirements for database design and installation

Hi,
As a database administrator, how to find out whether the database is design and installed properly?
Can you please what would be the requirements to be considered towards the databse design for application developer ?
thanks heaps !!!!

regarding that the number of execution is the main thing that affects the performance i said that already above " the application executed it 30 000" but you didn't read my answer correctly. I did not respond to that "answer" of yours as it was not part of your posting that I responded too. In your response, which I quoted, talked about non-sharable SQL retrieving 20 rows and after 3 years it retrieving a million rows. This has no bearing on whether the SQL is sharable or not.
I don't agree with you regarding that the design is not being done regarding considering the performance bottlenecks.So you decide on what the bottlenecks are up front, and then use these as database design considerations? I fail to see any logic or merit in such an approach.
i want to let you know that we in the telecoms environment have many problems in our databases because the people who designed those applications didn't take performance in consideration.I understand too well - and it is not that they did not take performance into consideration when designing the database, it is because the design is just plain wrong from the start.
You do not need to consider amount of memory available, number and speed of CPUs, bandwidth and speed of the I/O system, in order to design a database. These have no relevance at all during the design phase. Especially as the h/w that will run the design in production in a year's time can be drastically different from the h/w that will be used today.
No, instead you use a proper and correct design methodology and data modeling approach. Why? Because such a design by its very nature will make optimal use of h/w resources and will provide data integrity, scalability and performance.
Again i think design of the database application must take database performance bottlenecks in consideration like application which doesn't use bind variables if they took into consideration to avoid that it will help the DBA in the future but unfortunately most people doesn't do that. And as I said - using bind variables or not has absolutely nothing to do with the basic question asked in this thread: "+what are the requirements of database design+".
How does using/not using bind variables influence the design of a table? Determine whether an entity is in 3NF? What the unique identidiers are for an entity? These are the design considerations for a database.. not bind variables.
Yes, SQLs not using bind variables can cause performance problems. Not paying the electricity bill can cause a power outage for the database server. So what? These issues have no relevance to database design.

IDL Design and Client program

Hello forum, I've got a problem with IDL and interfaces design and with client program.
In my database, I have 3 tables: Calendar, Group, Staff. Each employee (of staff) has a calendar and belongs to several groups. So, I have designed the IDL as -->
module com
     module gmsoft
          module model
               module interfaces
                    struct GroupInfo
                         long id;
                         string description;
                    struct CalendarInfo
                         long id;
                         string description;
                    typedef sequence<GroupInfo> GroupList;
                    struct StaffInfo
                         long id;
                         string first_name;
                         string second_name;
                         string phone1;
                         string phone2;
                         string mobile;
                         string fax;
                         CalendarInfo calendar;
                         GroupList groups;
          module controller
               module interfaces
                    interface IControllerManager
                         boolean addStaff(in com :: gmsoft :: model :: interfaces :: StaffInfo staff);
                         boolean removeStaff(in com :: gmsoft :: model :: interfaces :: StaffInfo staff);
                         boolean updateStaff(in com :: gmsoft :: model :: interfaces :: StaffInfo staff);
                         com :: gmsoft :: model :: interfaces :: StaffInfo getStaff(in long id);
};As you can see, I've designed only one interface, the IControllerManager which will manage all requests in order to get an employee, or save one...
I don't know what the best is, if I have to design a StaffInfo (CalendarInfo and GroupInfo) as a structures(struct) or interfaces (interface).
I've tested both forms: As structures, I found the following problems:
1) On the client side, I can create an object of StaffInfo and pass it as a parameter to addStaff of the remote controller object. Is this object passed by value or by reference is it is created as a structure?
2) Using structures I can't use inherintace. (idlj mapped structures as final classes).
As interfaces:
1) I can't create objects of StaffInfo on the client side, because StaffInfo inherits from StaffInfoOperations, and the implementation (of remote interface) inherits form StaffInfoPOA that inherits from StaffInfoOperations. So, how can I create an object of StaffInfo on the client side, and pass it as a parameter to addStaff, for example? Is it possible?
Thanks for all in advance.
I will appreciate your help a lot.

I am wary of tasks that rely on reverse engineering or things like packet capturing because if for no other reason than you could spend alot of time on something and have it break in two seconds when they change the protocol or move to SSL or whatever.
To me it just seems like not a good plan. But that's me.
As far as you go. From a technical perspective this is about as good as it's going to get for you I think.

Difference between database design and schema design

Hi i have visited so many database websites and i found so many people saying we can design a data base for you. Is schema designing and database designing is the same. so many palces i find people saying we have to design data base first in order to create a physical databse. so i am little bit confused. are they same? and also what is the difference between data model and schema?

> the definition i found for logical data model, physical data model and the definition you
gave for logical database design, physical database design are the same.
Not correct. The physical design is the implemetation of the logical design. These two designs are at different levels. Also, the logical design will be the same. irrespective of the RDBMS product use.
What is incorrect is a designer/architect designing a logical design specifically for Oracle.. or specifically for SQL-Server. A logical design has nothing to do with the RDBMS product (or h/w platforms. app servers, web severs and operating systems used).
So the logical design will always be the same - it is RDBMS independent.
The physical design is fully dependent on the RDBMS product used. The same logical design will be implemented as different physical designs for Oracle and for SQL-Server.

Planning design and Manufacturing in SNP heuristic

We want to SNP plan the 'Design' and 'Manufacturing' processes to determine the start dates and capacity requirements for these processes. We are using SNP heuristic for planning.
We have modeled Design and Manufacturing in separate locations. We have an issue with modeling
For example the demand for SKU1 is 10,000 and SKU2 is 5,000
- Manufacturing Capacity is driven by the total quantity i.e. 15,000 (10,000 + 5000)
- Design Capacity is driven by number of SKUs i.e. 2 (SKU1 and SKU2). The quantity that drives manufacturing can change, but design is affected only by the number of SKU that should be designed
How can we model this in SNP?
A Dependant demand from manufacturing will be a function of the quantity and not a function of # SKU. Since the quantity varies by period, we can't maintain a ratio of quantity to # SKU also.

We are planning at an aggregated level (hundreds of SKU in an APO product). The number of SKUs in an APO product change over time. The product mix changes frequently and new SKU add / replace exisitng SKU.
But only the number of new SKU is relevant for design and manufacturing is driven by the total volume (of both old and new SKU).
I am currently thinking of an enhancement which will calculate the ratio of (volume / new SKU) per period and use it in the PPM. Is there a better way to model this contraint?
