Hi guy i'm newbie for Pentaho tool. Now i have some data source look like this
And i want to apply my data with this chart
I see a documentation already but I not understand every thing. Can some tell me some tip or solution please. Thank a lot
I've been looking at foreign keys and things because I have an assignment coming up so I'm trying to get a grasp on everything so I'm ready. I was looking at Linking ID from one table to data in another table and the answer mentions a way to do it in a many-to-many relationship but I can't see it anywhere, so I'd like to know how to do this.
When looking at the linked question, an example I'd like would be many ContactPerson could work for many Company.
I'm not sure if asking a question in this format is correct, but I thought it easier to link to the existing question rather than rewriting it.
Thanks in advance for any help.
You'll want a many-to-many relationship, which consists of 3 tables:
Company
ContactPerson
Company2ContactPerson
Example here:

Just to answer my own question, there's an in-depth explanation and examples which can be found here: http://www.singingeels.com/Articles/Understanding_SQL_Many_to_Many_Relationships.aspx
Tim roadley has similar answers but dint picture a mere of my questions.
Apple made amazing tutorial. In this sample you can know how to use Core Data with UITableView. Once I used it like introduction in Core Data.
Hope it was helpful.
I am building an application in which i am getting data from xml and data can grow dynamic,i am displaying location name on first view, and each location have multisubviews and sub views have multi hotels name, hotel image and hotel description and each hotel has further photo gallery, so at this condition i am facing problem how to store data on array i mean what will be smart logic to handle this and arrays should use as minimus as possible, Someone can help me???
Core Data has a good size learning curve, but a lot of boiler plate code is provided for you and the Apple documentation is pretty good. It's definitely worth learning, especially for things like this. For a starter, so you will understand it in perspective, your hotel will be your entity.
i've been asked to generate some demographic reports (crime rates, birth/deaths, etc) based on state and cities for the USA. I have all the demographic data (provided by our client) but can't seem to find any places which have the boundaries (read: LAT/LONG's) of the USA States and their cities.
Our data are Lat/Long points of data (eg. a crime, a birth, etc) and we want to get some mapped reports and also datamine using Sql server (we're using MS Sql 2008, but that shouldn't impact this question).
So .. can anyone direct me to where there are some state and city boundary sources? I know our government has all this information available for free at the US Census Bureau, but i can't seem to understand where it's found and how to digest this info.
I'm assuming that this info will be in the form of lat/long polygons (eg. a shapefile, etc) which i can then import into the DB and mine away.
Can anyone help, please?
A bit late, but in case anyone stumbles across this like I did:
To get the city boundary layers you navigate to "Download Shapefiles" for the year you're interested in and drop down to the city boundary layer, which is called "Places". (which is not an intuitive enough name for me...)
http://www.census.gov/cgi-bin/geo/shapefiles2011/main
That's the link for 2011's shapefiles.
I can suggest the post http://adventuresdotnet.blogspot.com/2009/06/sql-server-2008-importing-tigerline.html
Here's a link to the 2008 TIGER/Line shapefiles, and it sounds like looking at the TIGER/Line Shapefiles FAQ would probably be helpful -- other info at the main page for the 2008 data set.
I know the census is difficult to navigate at times. Try going to the National Atlas at nationalatlas.gov also the National map at http://nationalmap.gov/viewer.html
I think you are looking for GIS data. For example, I found US Census Bureau TIGER/Line 2007FE Shapefiles Mississippi, United States although I am not sure what you get with the download nor how to exploit the information...
HTH.
Was not able to use the tiger.. something web site. pain in the rear. Just download the file at the location below and may be trim according to your necessity.
