What is Big data all about .. ?

Hai to all
May i know what is the Big data all about ? ... how can i install and learn ?
is it good demand in market and is there any good pay for that ? in that market am from india... currently am working in Oracle Incentive compensation... my previous experience into siebel crm .....
Please can u suggest me good things
thanks

Well, there are many big data initiatives and there is a lot of interest in the market. So, yes big data is an interesting career path.
What is big data? Many things, but in general the "art" of collecting, correlating and understanding data - in massive volumes and at rapid ingest speeds - to drive businesses to better support their customers, their goals etc.
How to get started? Look around the forums, but also on Linked-In where you see job postings. Two avenues to consider for learning:
- Analytics, look at this Oracle link: http://www.oracle.com/technetwork/database/options/advanced-analytics/index.html
- Hadoop and NoSQL database, look at the big data appliance page, and possibly take a class on Hadoop
Hope that helps,
JP

Yes, it indeed boggles the mind. I'm of course referring to the fact that your post concerns Verizon Wireless products and services. This forum is dedicated exclusively to Verizon Communications services. As you probably know, Verizon Wireless and Verizon Communications operate as separate companies.
If you need help for a Verizon wireless product or service, it's best to direct questions to the Verizon Wireless forums. You can reach them by clicking on "Wireless" (either here or at the top of the page).
Good luck and I sincerely hope you get your issue resolved.

What is JSF really all about?

On another thread on this forum somebody posted these two very interesting articles, which for me helped clear up a lot of the confusion about what JSF is about.
http://www.internetnews.com/dev-news/article.php/3322641
http://www.internetnews.com/dev-news/article.php/3324521
But for me anyway they raised a bunch of new questions, which I am wondering if the JSF team can comment on? According to the articles, JSF is not an out of the box solution. It is really a framework for building frameworks and not for building applications. So far, after playing around with JSF for a few weeks, it seems to me that this is a true statement. Now here is the confusion:
1) JSF is supposed to prevent the fragmentation and vendor lock-in caused by all these non-JSF frameworks out there. But if each vendor needs to build additional infrastructure to make JSF into a suitable tool for application development what prevents fragmentation and lock-in caused by multiple JSF frameworks. Right now the problem is that a new Java web development framework pops up every day. It seems to me that in a couple of years a new JSF compliant framework could be popping up every day. So how does JSF hope to improve the current situation?
2) I am currently doing a study on the feasibility of creating such a JSF compliant framework, but it seems like a very risky proposition. The early risk is that JSF has too many quirks to really build a proper framework without access to the underlying implementation (my limited research has indicated this). Once all the "version 1" issues get shaken out, the risk becomes that in a few years JSF will decide to become an out-of-the-box solution and blow every other JSF compliant framework out of the water. It seems that we would have to be part of the expert committe on JSF to reduce the risks to a reasonable level. It seems like only companies on the expert committee are allowed to lock developers in. Any other vendor gets frozen out by the risk. So can a small player join the expert committee for future JSF versions? What is the criteria for joining?
3) A lot of people on The Server Side are ripping JSF for being too JSP-centric, which seems wrong to me. While JSP has a lot of flaws, it seems to me that most of the JSF users will be using JSP because it's the standard. So my concern is the opposite? I've asked a few questions on this forum and the answer has been, that there are limitiations in JSF when used from JSP, but not using JSP and creating my own view handler would be a solution. It seems to me that JSF has to work best in JSP because that is what most people will use. The answer to any question should never be: "it will work better if you don't use JSP". Otherwise I'm better off writing my own templating engine, which leads to more fragmentation, lock-in etc...

Here is a quote from the article:
"A standard for Web application development with visual components such as buttons, frames and radio buttons, JSR-127 was never intended as an out-of-the-box development tool. But judging from the negative reaction of some programmers so far, that's what they were expecting.
Craig McClanahan told internetnews.com that many programmers were expecting a working implementation of a framework that lets coders create Web applications using visual components. Instead, they got a specification that runs underneath the framework to allow portability between different tools. "
Seems to me this is true, especially since there are only a handful of simple components, validators and events. It seems that somebody has to build it out more, either tool/component vendors or business app developers. I think for the most part business app developers aren't going to want to do this. If you have to build extra infrastructure it kills the extra productivity you get from the component model. If it's component vendors it seems to me that the components could be generic an move from one JSF implementation to another, but I'm not sure how third party components would integrate with third party tools from other vendors.
For example, if I was to write a component library and a Dreamweaver extension to let users "paint" my components, I would have to hard code the Dreamweaver extension to generate and interpret the specific sets of tags in my library. It seems to me that this is a general problem, that the tool tends to get bound up with the library. Maybe really smart tools could be built to handle UI components in a generic way and let you import any tag library, but I think this is much harder to do with tags then with Swing components, because very often a single visual GUI component is a composite of many tags, so how do you explain the interrelationships to a tool in a generic way. It seems you would need some very clever and complex meta-data, or some way to attach generic tag editors to components that could ride along with the components from tool to tool. I haven't seen that in the spec, but maybe I'm missing something.
Now, if a vendor decides to use a different templating engine altogether, which seems to be what a lot of people want and the spec and implementation seem to incourage, then all bets are off. The tools and the template have to be bound up together.
So once you pick a templating engine, a vendor tool and a component library for your application, it becomes difficult to to switch to another engine, tool and component library unless you want to abandon tools all together and just use a text editor, or rewrite your user interface. You're back to lock-in and fragmentation, same as now.
Now as a potential component vendor, I see this as a big risk. I write a component library and tool and so do a million others and we compete on the merits of our tools and libraries (I'm very comfortable with that). But developers start complaining about the fragmentation, and the only solution is for the extra infrastructure to be built right into JSF so it's standard and every tool can manage the same tags. Now I have to rewrite my tool, and my component library is worthless. So do I want to become a component vendor? Maybe if I was on the expert committee and I could prevent new standard JSF features that blow me out of the water. Otherwise it's a very risky undertaking. And statements like this in the spec "It is anticipated that the number of standard component classes will grow in future versions of the JavaServer Faces specification." don't help anything. If I'm a developer should I use a third party library or wait? If I'm a potential vendor should I even bother?

File Sender and Mail Receiver .....what is the error all about?

Dear All,
I am trying to send a file using mailpackage to my Lotus Notes id.But it is giving the below mentioned error.

3.What all Configuration I need to change,if any?
4.How to solve the error?
Without running the scenario,when I went to Monitor ,it was showing,

Please help me to solve this problem.
Thank You

No Stefan,
I don't have SP10.
Do I need make any new configuration on the Mail Server side or i can carry on with the existing corporate one (which I am not supposed to touch)?
I haven't created any mail server of my own.But I want to send that file to my corporate domain or my yahoo domain for example.Now should I need to make any new configuration or configuration changes on my Integration Server?
I am very much confused in this regard.I have not made any other configuration other than that of Mail Adapter and File Adapter(ie,only XI related configurations).
I didn't even configured my own smtp server.
This is what I have done so far.Can you please through more light on it?
Thanks in Advance,

Big data Implementation in sql server 2008 r2

Thanks in Advance.

Can Some one please explain what is big data and implementation of big data or usage of big data with clear explanation, Screen shots will be more helpfull.
Unfortunately, the data is to big to fit into a screenshot. :-)
Big data is one the most recent buzzwords in the computer industry. SQL 2008 R2 is not a good tool to work with big data.
Big data is about analysing patters in big amounts of data, often semi-structured or unstructured. Places like Facebook, Google, Amazon spend a lot of time in analysing click logs to see which pages you went to and from, in that way they can predict your
interest.
Much of the Big Data analysis is performed with Hadoop, which is an open source offering that works on a non-relational database. Someone mentioned PDW as Microsoft's offering in the space, but Microsoft works with Hadoop as well, and they also marry
them together.
Anyway, if you relaly want to get a grip what this is all about, listen David DeWitt's excellent keynote from the PASS Summit 2011. You will have to register and become a member of PASS if you aren't already. PASS is free and it is a non-profit organisation
for SQL users world-wide.

Big Data example

Hi all,
I hear the term big data for quite some time now...
Whenever I look on the web I only find infrastructure explanation...
What does it mean in terms of T-Sql coding? structural storage on sql server (are tables used?)? Is there a "Hello World" example for big data.
Sorry if my question is a bit wierd but that's how I've always started learning any new programming language or API.
Thanks in advance,

BIG Data with OBIEE

What is Big Data? How to handle that in OBIEE?
Please give me the steps how to implement that.
Thanks.

Hi,
Not sure what you want to achieve here... however.. what I read is that you would like to have a way to get unstructured data into structured so you can report on it using OBIEE. (Correct?).
Depending on the amount of data and the things you need to do to it before you can structure it you can create a map/reduce function and use Hadoop. There is a connector to push the hadoop results into the Oracle database. Then you could use OBIEE to report on the now structured data in the Oracle database.
As I do not know the details of what you like to achieve,..... this is a solution I would start looking into if I where you.

If I use Informatica Big Data Edition do I still need to use Hadoop or MapR or any other similar systems to process data? What all activities will be specific to Informatica BD or Hadoop?

If I use Informatica Big Data Edition do I still need to use Hadoop or MapR or any other similar systems to process data? What all activities will be specific to Informatica BD and Hadoop?1. My query is to process both structured and unstructured data in real time, so is Informatica Big Data Edition suffecient of do I have to use Hadoop or MapR or Cloudera etc to process data. If so then what all activities will be performed be Informatica and what all activities will require Hadoop.2. Also for scheduling do I need to go for ActiveBatch or I can perform it be native Informatica Scheduler itself?

whats all about MiniSAP 4.6 d ? whast the difference between MiniSAP WAS 6.10 and MiniSAP 4.6 d. I have MiniSAP WAS 6.10 but it doesnt have BASIC SAP R/3 modules like FI-CO,MM, SD...
does MiniSAP 4.6 d come with the basic SAP R/3 modules like FI-CO,MM, SD etc.. ?
Any info posted in this regard would be greatly appreciated.
Thanks
Shirin

Hi Vikas
Thanks Again !!
I have got mini sap 6.10 in my machine. it doesnt have the basic r3 modules. its designed only for WAS features.
it has got a data and kernel CD with that. is it the same with mini sap 4.6 d too ? any idea ?
My big Question is, if I install mini sap 4.6 d on my machine after uninstalling mini sap 6.10 , do I still get the basic r3 modules installed on my machine

Back up all data before proceeding.
Launch the Font Book application and validate all fonts. You must select the fonts in order to validate them. See the built-in help and this support article for instructions. If Font Book finds any issues, resolve them.
Start up in safe mode to rebuild the font caches. Restart as usual and test.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t start in safe mode. In that case, ask for instructions.
If you still have problems, then from the Font Book menu bar, select
File ▹ Restore Standard Fonts...
You'll be prompted to confirm, and then to enter your administrator login password.
Also note that if you deactivate or remove any built-in fonts, for instance by using a third-party font manager, the system may become unstable.

Might be RAM related if the above tip describes what happened.
If not, and your data is not backed up, and it won't startup, read this tip:

What is the best big data solution for interactive queries of rows with up?

0 down vote favorite
We have a simple table such as follows:
| Name | Attribute1 | Attribute2 | Attribute3 | ... | Attribute200 |
| Name1 | Value1 | Value2 | null | ... | Value3 |
| Name2 | null | Value4 | null | ... | Value5 |
| Name3 | Value6 | null | Value7 | ... | null |
| ... |
But there could be up to hundreds of millions of rows/names. The data will be populated every hour or so.
The goal is to get results for interactive queries on the data within a couple of seconds.
Most queries look like:
select count(*) from table
where Attribute1 = Value1 and Attribute3 = Value3 and Attribute113 = Value113;
The where clause contains arbitrary number of attribute name-value pairs.
I'm new in big data and wondering what the best option is in terms of data store (MySQL, HBase, Cassandra, etc) and processing engine (Hadoop, Drill, Storm, etc) for interactive queries like above.

Hi,
As always, the correct answer is "it depends".
- Will there be more reads (queries) or writes (INSERTs)?
- Will there be any UPDATEs?
- Does the use case require any of the ACID guarantees, or would "eventual consistency" be fine?
At first glance, Hadoop (HDFS + MapReduce) doesn't look like a viable option, since you require "interactive queries". Also, if you require any level of ACID guarantees or UPDATE capabilities the best (and arguably only) solution is a RDBMS. Also, keep in mind that Millions of rows is pocket change for modern RDBMSs on average hardware.
On the other hand, if there'll be a lot more queries than inserts, VERY few or no updates at all, and eventual consistency will not be a problem, I'd probably recommend you to test a Key-Value store (such as Oracle NoSQL Database). The idea would be to use (AttributeX,ValueY) as the Key, and a Sorted List of Names that have ValueY for their AttributeX. This way you only do as many reads as attributes you have in the WHERE clause, and then compute the intersection (very easy and fast with sorted lists).
Also, I'd do this computation manually. SQL may be comfortable, but I don't think It's Big Data ready yet (unless you chose the RDBMS way, of course).
I hope it helped,
Joan

i believe it's because on the "system requirements" it says that if running on vista, it needs to be on a 64-bit system. Mine runs on 32 and doesn't seem to work. it crashed my computer... big time.
I am not computer savvy though... could be wrong.
