database design - Need help modeling a fact table -

-

I'm taking my first step to datawirehousing.

I am Kimball & amp; Has bought the excellent book "Data Warehouse Toolkit - Third Edition"; Ross, who explained to me how to understand the fundamental concepts.
Today I have started preparing my second data mart, but I'm already struggling with a (maybe stupid) problem, suppose I'm modeling a simple selling event: a small fact sheet Will be: 

  DATE_ID | CUSTOMER_ID | PRODUCT_ID | QUANTITY   
 Each dimension has many relationships with others, as explained on the book and the web. Next 
 I want to add some more dimension, like the carrier:  
  DATE_ID | CUSTOMER_ID | PRODUCT_ID | CARRIER_ID | Quantity   
 Dimensions are still in many-to-many relationships. 
 Now, I have been asked to add detailed information about the delivery (maybe a dozen or more), a bunch of dates, the number of routing, boxes and palettes, different flags etc., so I have the delivery dimension table Was thinking about. My first attempt was:  
  DATE_ID | CUSTOMER_ID | PRODUCT_ID | CARRIER_ID | DELIVERY_ID | Quantity   
 But ... surprisingly, the fact sheet is not in many relationships now, so I thought: "Well, I can reapply it, because now Other dimensions are actual properties of distribution ", but this will be  
  DELIVERY_ID | PRODUCT_ID | Quantity   
 And my fact table will now have 2 dimensions. 
 Now, in other situations I will treat delivery as a dinerett dimension, but since I have to add a lot to it with the attributes, which route I do not follow:  < Ul> 
  •  To create a delivery dimension and create a fact table refactor?  
  •  Throw them into the facts table?  
  •  Create a delivery dimension and putting DELIVERY_ID in the fact table shows that it is only a thin dimension?   
     Perhaps it is not so easy to choose between dimensions and facts   
     
     
     As you describe it,  Distribution  is a  Sale . Therefore delivery should be a separate fact sheet.  
     Of course you always have a "project" (to say this) in one dimension, if you do not need additional complexity, for example, say that you only know some simple facts about delivery Needed: For example the carrier and delivery date. So you can use DELIVERY_ID in sales and you can register these information in the delivery dimension.  
     But if you have to register the complete complication of delivery (two or more delivery related to a sale can be done, and two or more sales relative to a distribution) you need two fact tables.

    python - Receiving "KeyError" after decoding json result from url -

    -
    I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

    .net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

    -
    "itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
