I am trying to understand as to how to post clean data tables in stackoverflow to ask questions. When I try to copy questions from Excel I find it difficult to maintain clean structure and when I try to use the code sample block too I find it difficult to arrange the data when there are more than 5 columns and multiple rows.
Thanks to #Martheen.. The link https://tabletomarkdown.com/convert-spreadsheet-to-markdown/ helps convert excel and csv file data to proper table structure and it can be copied onto stackoverflow platform for asking questions!

I am able to create tables and load several of them with data but when I go to access the data again to retrieve data the program is telling the table does not exist.
I am creating the tables from within the viewcontroller. I read in one of these posts that it should not be done from within viewcontroller but from another class. My question is who should this be done. I would also like to be able to insert and retrieve data from a second viewcontroller.
How is this accomplished? What type of class needs to be set up to keep the database open throughout the entire program? I have searched the internet for answers but have not found what I am looking.
An example and some explanations would be most helpful.
If more information is needed I can provide.
Thank you in advance
Basically, I am new to jqgrid and have been tasked with maintaining a database table that has a relational secondary table.
From what I've read the "editoptions dataEvents" is the ticket. What I cannot find is an example of how to implement it. All I've found is code fragments but I am too new to understand how the fragments fit into the overall picture.
A basic and complete example would be wonderful.
Any help would be appreciated.
best regards
I am working on a project involving force layouts in D3,for which I have to create my sample data with over 1000 nodes that may or may not be linked to each other. I find it tedious to create the links manually in a cvs or excel. Is there any way that I can create the links through a code and also use it in the project where the user can create new links or add new nodes. I have gone through several examples, but I feel I am missing something. Some guidance on this would be great.
Thanks & Regards,

I have read lot of blogs\article on how different type of industries are using Big Data Analytic. But most of these article fails to mention
What kinda data these companies used. What was the size of the data
What kinda of tools technologies they used to process the data
What was the problem they were facing and how the insight they got the data helped them to resolve the issue.
How they selected the tool\technology to suit their need.
What kinda pattern they identified from the data & what kind of patterns they were looking from the data.
I wonder if someone can provide me answer to all these questions or a link which at-least answer some of the the questions.
It would be great if someone share how finance industry is making use of Big Data Analytic.
Your question is very large but I will try to answer with my own experience
1 - What kinda data these companies used ?
One of the strength of Hadoop is that you can use a very large origin for your data. It can be .csv / .txt files, json, mysql, photos, videos ...
It can contains data about marketing, social network, server logs ...
What was the size of the data ?
There is no rules about that. It can start from 50 - 60 Go to 1Po. Depends of the data and the company.
2 - What kinda of tools technologies they used to process the data
No rules about that. Depends of the needs. To organize and process data they use Hadoop with Hive and Pig. To query data, they want some short response time so they use NoSQL / in-memory database with a shorter dataset (refined by Hadoop). In some cases, company use ETL like Talend in order to go faster.
3 - What was the problem they were facing and how the insight they got the data helped them to resolve the issue.
The main issue for company is the growth of their data. At a moment, the data are too big and it is impossible to process with traditional tools like Mysql or others. So they start to use Hadoop for example.
4 - How they selected the tool\technology to suit their need.
I think it's an internal problematic. Company choose their tools because of the price of the licence, their own skills, their finals needs ...
5 - What kinda pattern they identified from the data & what kind of patterns they were looking from the data.
I don't really understand this question
Hope it will help you.
I think getting what you want is a difficult job getting data little by little from different resources. just make sure to visit these links:
a bunch of free reports. I am studying the list right now.

and the famous McKinsey Report:

I've looked through GotReportViewer.com in some detail, but I just can't find enough of a clue to really work out how to do this.
I need to effectively join two datatables (client-side) on a primary key, and show some information from one table in one area, and other (listed) information from the other in another.
From what I read, it's possible (though I haven't managed it yet) to join the tables together to form a third, and use filters to achieve this, although it seems like a lot of work when you're building the datasources dynamically as I am.
Is it possible to generate two datasources that share a key (one implementing the 'many' part of the 1:many relationship), and create a master-detail report that uses both?
If there are any simple tutorials (C# or VB would be fine if I need code) for this I'd appreciate a pointer. There are several unanswered questions here on similar topics to this, which is a worry!
TIA
I gave up on Microsoft's reporting tools, switched to Crystal, and life became a lot easier. Importing an XSD generates a data source, in which tables can be easily linked.
Job done.
