Design , Architecture and Framework

What is the difference between Design , Architecture and Framework?

Design and architecture could mean the same thing, depending on the context. A framework can follow a design/architecture.
I would start by looking up the words in a dictionary by the way, you'll get some immediate hints.

Best architecture and design pattern to use

I am currently designing a moderately sized LabView application and cannot decide on the best architecture/design pattern or combinations thereof to implement.
The program basically polls an instrument connected to a serial port continuously at a 2-10Hz rate. When operator clicks a button to start a run, the polled data is then filtered, has math functions performed on the data, writes collected data to files, and produces reltime graphs and calculates point-by-point statistics. At the completion of a run, some additional data files are written. I pretty much know how to accomplish all these tasks.
What is also required is main-vi front panel interaction by the operator to access a database (via a C# dll with .Net) to query for specifications to apply in order to determine pass/fail status. Setup conditions also need to be changed from time to time by the operator and applied to the data in real time (ie- a measurement offset). I have prototyped the database portion successfully thus far.
For the main vi, I started off using the Top Level Application Using Events design pattern (Event structure within a while loop). Copious use of bundled clusters and shift registers keep the database data updated. I cannot figure out how to have the top level vi concurrently poll the serial device as outlined above. The Event structure is only active when defined control values change, and use of a timeout is no help since it prevent data from being collected while the user is accessing the database. All database and setup parameters must be applied to the data as it comes in from the serial port. Error trapping/recovery is a must.
I believe what I need is two parallel processes running under my main vi (one for database and setup, the other for polling and data processing/display, but what would be the preferred choice here?
Revert back to a polled loop in lieu of Events, use notifiers, occurrences, user-defined events, Producer-consumer loops?
It�s been about 3 years since I have had an application on this level (which used a state machine architecture), and a lot has changed in LabView (using 7.1 Prof Devel). I am currently having a mental block while trying to digest a lot of features I have never used before.
Suggestions Welcome!
Thanks.

"It’s the questions that drive us.”

I suggest a (3) state machine(s) architecture. The first is the user interface. Your main VI is a good start. Another state machine handles the instrument I/O (your serial polling). The third handles all data processing. The three loops run independently. Each has a wait to allow LV's scheduler to share CPU time among the loops. I like queues or functional globals for inter-loop communications.
This allows a lot of flexibility. Each portion can be tested alone. Each can have different timing and priority.
Spend some time thinking about what needs to be done and plan the structure carefully before you do any coding (except for little test programs to try new ideas).
I also like Conway and Watts "A Software Engineering Approach to LabVIEW", published

Difference between n-layer software architecture and MVVM design pattern?

hello everyone,
I am not clear with this concepts of Software architecture pattern and design pattern.
I am developing an wpf application using MVVM. Now, my question is, does MVVM come under n-layered architecture?
or n-layer architecture and MVVM both are different?
Regards,

"
Now my question is, i want to process the data which i get from database. where should i write that processing logic after getting the data from database? in model classes? or in view model classes?
The model is however the data comes from wherever it comes from.
If there is any processing after you get it then that would be in the viewmodel.
The viewmodel adapts your data to the view.
If it needs any adapting then the viewmodel does that, not the model.
EG here
protected async override void GetData()
ThrobberVisible = Visibility.Visible;
ObservableCollection<CustomerVM> _customers = new ObservableCollection<CustomerVM>();
var customers = await (from c in db.Customers
orderby c.CustomerName
select c).ToListAsync();
foreach (Customer cust in customers)
_customers.Add(new CustomerVM { IsNew = false, TheEntity = cust });
Customers = _customers;
RaisePropertyChanged("Customers");
ThrobberVisible = Visibility.Collapsed;
That logic is in a viewmodel.
in this context , in which layer the viewmodel and model classes are put under in n-tier architecture?
They're in two of the n layers/tiers.
Or they're in one.
Depending on how someone decides to classify a layer or a tier.
There is no absolute definition.
Why would you care?
Hope that helps.

Hi Poojith
Not sure if this would solve your requirment but just in case might be helpful:
1. We can mix up the HTML and HTMLB components in the JSP Page. However, can access only the HTMLB components in the controller. The following link refers to what customizations are offered by the HTMLB framework:
[http://www.sapdesignguild.org/resources/htmlb_guidance/]
2. Another option would be to use AbstractPortalComponents or a simple web app if that's feasible. (where custom UI themes, css and layout are more in control of the developers.)

Hi Dhiyadav,
thank you for your reply it cleared some doubts that were in my mind but i need your more support to guide me a converged access deployment which i am going to deploy within few days.
i have
2x5508 in HA as MC
30x3850 switches, and all will be used as MA(s) with multiple SPGs
2X5508 1:1 as an anchor controller
1xISE 1.3 for guest access
1xCPI for wireless mgmt and monitoring purpose
1xMSE3355 with wips and context aware licenses
200x cisco 3702i WAP
50x WSSI module for monitoring the channels
can you please put a light on the design and guide me that which are the best possible solutions to get this job done very smoothly.
i will also let you know about my proposed design scenario but for sure i need your recommendations as well :)
so,
i will use 2x5508 wlcs in HA as a MC which are AP-Count and HA licensed..
3850 switches will be MA and i ll configure SPGs per floor switches stacks
WAPs will join on these 3850 MAs base on each floor
i would have 2 ssid like employee and guest
i will configure them on each 3850 stack MA along with their SVIs for users access like (empolyee and guest ssid)
here my question is for guest ssid and its vlan... do i configure it here or on anchor controller???
i want ISE to be integrated with wireless for employee 802.1x and for guest web Auth. so, how i will integrate ISE with wireless. i mean weather i will integrate it anchor controller or with each 3850 MA???
between foreign and anchor controller i will use new mobility instead of old EOIP!!!
where shall place ISE in my network, in DMZ or with Core switch?
my target for guest users to do not have access to any corporate network sources ?
MSE:
can i use both wips and context aware on the single MSE box?
if yes, than what is the best practice for configuring them?
are each 3850 MA will be added in MSE?
WSSI module . will be used for monitoring purpose for wips and context aware profiles.
all access point will be worked in local mode for serving users access.
thank you

OWB - Installation Architecture and Infrastructure configuration

I thought it is a good idea to throw this out to the OWB community to see what your thinking is.
This is my first project; we are currently on detail design. The Client requests a document that covers the following details.
Architecture and Infrastructure configuration for OWB - Oracle Warehouse Builder – which is to be targeted at an ehosting data centre.
•     What is the best practice either from Oracle
•     Is it best to go for a 2Tier or 3Tier architecture
Infrastructure being of interest is:
•     The use of Application server and web service for giving visibility and access to the runtime / design repository via the repository browser.
•     The applicable application service i.e.: Control Centre Service
Can this distributed over multiple servers if you application server differs from you database server.
•     Do you have any information similar to this you compiled in the past that I can use
•     Or is there any source you can direct me to get this kind of information

Can this distributed over multiple servers if you
application server differs from you database server.This is not an OWB question. This is a database question. You are asking something like 'can I run Oracle with Apache with Tomcat?'. Simple answer is yes. Compex answer is load balancing?

Establishing BPM, SOA and Enterprise Architecture and 'Governance'

Good day all,
(Originally posted on LinkedIn Oracle BPM group)
(This post can also apply to those implementing SOA and/or Enterprise Architecture)
After reviewing Oracle's IT Strategies from Oracle (ITSO) reference library (http://www.oracle.com/technetwork/topics/entarch/itso-165161.html) there does not seem to be anything specifically created (yet) targeting a BPM Governance Framework.
It is mentioned in a document in the above mentioned library, titled "Business Process Engineering", document ID E20216-03, file name of, oracle-pg-bpm-bus-proc-eng-r3-0-292099, page 5-2, 3rd paragraph, and I quote, " (see A Framework for BPM Governance for more information). Yet there is no link or section to or for said reference nor anything else within that document. Disappointing.
The closest and so far best approach I feel is a PDF file titled, ONE 2010-ART-BPM Governance Framework-VKhusidman-v51, authored by Vitaly Khusidman, titled "BPM Governance Framework", BPTrends ▪ July 2010
In this above document Dr. Khusidman recommends utilizing TOGAF as a framework for establishing the BPM Governance Framework. This also seems like a sound approach for those addressing the Enterprise Architecture (and governance which is a part of that larger 'whole') as well as SOA and BPM, especially those moving to a combination of SOA and BPM.
What are the thoughts and approaches being used by others, who may also be using some of Oracle's products and tools, and tasked with addressing the whole enterprise and/or SOA-BPM combined?
Cheers

IMO this one is legitimate.

Guidelines for design/architecture review

I'm conducting a design/architecture review for a part of our system that needs seriously re-visiting. I'm going to be formally presenting the review and was hoping for a few pointers.
Does anybody have a set of guidelines they follow for such a review? Are there any suitable articles or books for me to refer to?
Thank you.

I'll probably be stating the obvious for you but:
- Direction Enterprise
      - what's on for the future
          - 6 mo
          - 12 mo
          - 2 yr
          - 5 yr
- Weak points of existing systems: (contrasted with Enterprise Direction)
      - Why: what makes it a week point
      - to what extent is it believed to impact current operation
      - how does it hinder future growth
- Prioritize Systems/Component replacements
      - imediate (right now)
      - short range (1 year)
      - middle      (2 years)
      - long range (5+ years)
- Return on Investments
      - try to quantify $ or empowerment to meeet Enterprise Direction
      - impact of doing nothing

Design / Architecture from Requirements

Is there a good article / book with real examples of how to arrive at a system design / architecture from requirements ??
Also, is there a defined way to organize the requirements captured so that it would be easy to translate it into design ?
We have captured our requirements from a data and process perspective. I have a hard time to organize them and break them up and to finally translate them into design.
Any pointers would be of great help to me.
Thanks !!!

Is there a good article / book with real examples of
how to arrive at a system design / architecture from
requirements ??There must be thousands.
Also, is there a defined way to organize the
requirements captured so that it would be easy to

We have captured our requirements from a data and
process perspective. I have a hard time to organize
them and break them up and to finally translate them
into design.
Any pointers would be of great help to me.In what form have you "captured your requirements from a data and process perspective"? To me the output of requirement analysis is in the form of formally described test scenarios. That is, I distill User Stories (Use Cases from the user's point of view) from the verbal requirements, and derive scenarios from them; these scenarios are basically descriptions of acceptance tests.
Given that, I take the first (the most simple) of these user stories and break this up into as many independent, "atomic" tasks as possible. At the point I'm describing these I usually have a pretty good idea of what interfaces and classes will be needed, and I can start writing unit tests. Often, when I feel during "task analysis" I'm just literally writing in English what my test code will be, I skip formally describing them and just write the tests straight away.
When the unit tests are ready design is done, skeleton implementations are there and the rest of the code pretty much writes itself ;-)
Next story, same deal; always adding tests & refactoring & regression testing.
story -> scenarios -> acceptence tests
tasks (-> scenarios) -> unit tests
refactoring ->additional classes -> new unit tests
That's, in a nutshell, how I do it. As you can tell, this is leaning close to the eXtreme Programming way of working; and as you can equally tell, I believe strongly in test-driven development, designing from test code, and emergent design.
So if I were to point you to any articles or books, I'd tell you to aim your google at "extreme programming" and go from there. The first two hits will be the two main XP web sites.
As I said there are many different methodologies each covering more than just A->D, and a lot has been written about them. The above is my personal preference - you'll have to evaluate if it can be suitable for your project and team.
One final pointer (I'm going on aren't I) is this: whichever way of working you use, evaluate it constantly. For example, if you decide to make a lot of UML diagrams, evaluate the time spent vs the return. If your team feels there really isn't enough actual benefit, stop doing it; if they feel it does pay off, by all means keep doing it.

Design architecture Difficulty

Hello all. I'm having some difficulty comming up with a viable and stable design architecture for the problem listed below.
We are downloading 5 files from a server through TCP/IP.
Each file consist of say 20 parts/chunks.
Each part is further divided into chunks of say 15.
So, 15 chunks make 1 part. 20 parts make 1 file.
Each chunk is say 1MB where each part is about 15MB in size.
Now, we are downloading these files through 30 available TCP/IP connections.
Each connection can download 1 chunk at a time.
So, we have 30 chunks being downloaded in parallel through 30 TCP/IP connections.
So, 2 parts of a file (i.e. 30 chunks) are downloading at once.
User may pause the file being downloaded (i.e. file 1) and start downloading a different file (i.e. file 4).
Now, these 30 TCP/IP connections will have to abandon downloading file 1, and be reused to download file 4.
When file 4 is finished, the user decides to start downloading file 1 again. The progress of downloading file 1 should start from where it left off.
The progress may only be deleted when user Cancels the download.
Basically, the above section describes the jist of it. Any sugestions are appriciated.
Kas

I have no LV on this PC, however,
How about an array of cluster with chuck name / PostID#, priority weight and status (waiting for dl, in progress) , whenever a connection is free / a chunk download has finished, the element with the highest weight is downloaded.
Could also be a queue or a AE ....
Commandline controllable NNTP reader/ downloader may already (or should I say may still?) exist.
If bandwidth is limited and you have multiple downloaders, why not use a torrent like approach?
Still remember the time reading this forum with nn (or was it tin?) on a freebsd system connected via telnet to a DEC VT102

Architecture and Implementation

Hello All,
I am kind of new to this field and I have started building applications, and now I have two terms that I would like some to explain to me. Sounds simple and crazy but, what do the terms "architecture" and "implementation" mean in the perfect Hyperion sense. For example, what does an Essbase architecture do, for example, does he design cubes? etc and other question is about "implementation" what does it mean when someone says "I have implemented 3 planning applications?
If someone could spare a little of their precious time to explain these terms that would be wonderful. A link would be great as well.
Thanks

Its recommended to maintain three environment.s
1. Development Environment ( BOD )
2. Quality Environment ( BOQ )
3. Production Environment ( BOP )
BOD : Development environment where you do all development. This environment may not be as same as Production with respect to server, resources and so on.
BOQ: Quality environment where Business users do testing. This environment is expected to be same server, same version when compared with Production. Resources such as memory and number of servers could vary.
Once approved by Business Users, content will be migrated from BOQ to BOP.
BOP: Production environment only meant for usage not for any development. UAT happens here once again to check the functionality of reports & other objects
In general, the BOQ and BOP content is always same except the objects which are under Business Users testing.
When it comes to backup, we must take frequent backups for CMS database, Input FRS, Output FRS and Audti Database.
The fequency depends how frequently the production environment is being updated.

Sharepoint Designer 2010 and Visio 2013

I am testing out Visio Professional 2013. I can import a VWI file from Sharepoint Designer 2010 and I can export a VWI file from Visio. But when I try to import the VWI file created in Visio 2013 into sharpoint Designer 2010 it appears to work, as
I don't get an error, but the work flow never appears. Any thoughts?

Hi,
Based on my research, if it is SharePoint Designer 2010, then the only edition that supports SharePoint workflows is Visio 2010 Premium edition.
And if you use Visio 2013, then it need to use SharePoint Designer 2013.

Design view and browser view in DW are different than when I view from local folder

I'm brand new to Dreamweaver CS5.5 and here is my problem:
I've made an html page in dreamweaver with a banner, with an additional graphic and some text on top of the banner. It displays just fine in every browser when I view from the local folder, but when I open DW and view, it displays incorrectly in all three design, live and browser views within DW. If I make changes to the css file until it views correctly in design view, it no longer displays correctly from the local folder and it still doesn't view correctly in live or browser view within DW. If what I'm doing isnt going to display accurately in any of the views provided by Dreamweaver as compared to the live server, whats the point in having this software? I could just keep building webpages in notepad and uploading with CoreFTP.
Any suggestions? Is it some setting that I dont know about that I need to change within DW? Please help.

align="center" is deprecated (obsolete) code in XHTML & HTML5 doc types. Instead of styling markup with HTML, you should be using CSS.
CSS
.center {text-align:center}
HTML
<p class="center">some centered text here</p>
With respect to break tags, in XHTML doc types the correct syntax is <br /> not <br>. However your usage of line breaks is inconsistent with good symantic markup. Use headings <h1> <h2> <h3> <h4> for important keywords. Use <p> for descriptive paragraphs. Use <ul> <li> or <ol> <li> for lists. Line breaks should be used minimally if ever.
XHTML doc types require all tags to be lowercase. Uppercase tags will throw errors.
Your design is too rigid. When text size is increased in browsers, your content is unreadable. See screenshot.
SOLUTIONS:
1) DO NOT USE POSITION ABSOLUTE. You don't need it. Absolute positioning removes content from the normal document flow resulting in a jumbled mess. Use default CSS positioning (none) with margins, padding & floats to align elements.
2) Remove HEIGHT values from all CSS containers. Height limits a container's capacity to hold more content when needed. Container height should always be determined by the amount of content it holds; not explicit values. If required to reveal a background image, for example, use CSS min-height instead of height.

Designer 6i and 10g on the same machine?

I have Designer 6i and corresponding repository on my machine.
The problem with 6i I can't save diagramm in HTML format
I believe I can save in HTML format in 10g or other?
Can I install on the same machine 10g designer?
should I configure new repository?
TIA

See my update on your earlier question.
As for running 6i and 10g on the same machine, yes you can do it. You just have to install them in separate Oracle Homes, and be careful when you tell them which version of EXP and IMP to use. There is one MAJOR caveat, however. They cannot use the same Designer Repository - 6i client won't talk to a 10g repository and 10g client won't talk to a 6i repository. You can upgrade a 6i repository to 10g with the RAU, but take a backup before you do - the only way to go back is to restore your backup. Besides, I think that if you upgrade to the last supported version of Designer 6i (you should be able to get it from MetaLink) you will get the Publish Diagrams utility.
Frankly, my opinion is that there is only one reason to stay on 6i - if you need to generate and support 6i client/server Oracle Forms. If you don't use Oracle Forms, or if you have moved on to Web Forms with the middle tier Forms Server, I'd recommend an upgrade to Designer 10g and Developer 10g.
