Dimension table is associated with N number of fact tables

Salvation by the Expert,

In the case of a fact table star schema is associated with the N dimension tables, it is possible to join a table of size N with the number of tables of facts... Please let my know your suggestion...

Thank you to

Harish

Hello

Yes, it's quite possible. A dimension can join the many fact table. For ex: temporal dimension and w_employee_d are classic examples of this behavior.

Kind regards

Problem with populating a table of facts, of dimension tables

My goal is there are 5 dimensional tables created

Student-> primary key s_id, upn(unique pupil no), name
Rank-> key primary g_id, grade, exam_level, values
Object-> key primary sb_id, subjectid, subname
School-> key primary sc_id, schoolno, school_name
year-> y_id primary key, year (like 2008)

S_ID g_id sb_id, sc_id, y_id are sequences

select * from student;
S_ID UPN FNAME COMMONNAME GENDER DOB
==============================
9062 1027 MELISSA ANNE       f  13-OCT-81

It's basically the dimensional point of view

According to the given specifications, now need to create a table of facts like facts_table that contains all the primary keys of tables IMG as foreign keys in it.

The problem is when I say, I'll look at an example of smaller that the reality of dimension tables 5 let say there are 2 student dim tables, rank with s_id, g_id as the p key.

create materialized view facts_table(s_id,g_id)
as
select  s.s_id,g.g_id
from   (select distinct s_id from student)s
,         (select distinct g_id from grade)g

The result is a massive duplication as there is no join between two tables. But basically there is no common things between the two tables to join, how to solve?

Think of it as when I do for 5 tables the amount of duplication being involved, why there is not enough tablespace.

I was hoping that if there is no other way then don't create a fact table with just a column at the start

create materialized view facts_table(s_id)
as
select s_id
from student;

then

alter materialized view facts_table add column g_id number;

Then fill this column g_id fetching all the grade table g_id values using some sort of loop, although we shouldn't use pl/sql, I don't know if it works?

All of the suggestions.

Concerning

HP LaserJet M425dn MFP 400: This product number is not associated with the supplied serial number.

I'm checking the the warranty status of my M425dn.

The warranty registration page, I enter my serial number and click on submit. Website "this product can be identified by the serial number only. Please enter a product number below or change the serial number above. »

I then enter the number of related product as shown on the back label of the device: CF286A. I click send again. Now the page returns "this product number is not associated with the supplied serial number. Please check your records and make any necessary changes. »

I have triple checked my serial number and product number. I so need to know the status of the guarantee of this device. What should I do?

Yes, I am aware of the presentation of the printer and where are product information stickers. In fact, I have pictures of the thumbnails so that I can refer to them without having to look at the back of the unit whenever I need something.

(In most circumstances, I could use web interface of the device to get information. "(But for some reason, the number of product is not included in the page of information of the device web interface... or any other page)."

My unit sticker clearly shows CF286A without extra character.

However, I now know why I have a problem. After stop HP 800-474-6836 support (moved to 800-334-5144) and passing through the quick second support 75 (don't fall for the trick of being told to go online - wait around 10 seconds of silence for the next part of the guest and eventually you will get to the point ask the bot to phone the model information), I was able to speak to a representative very nice who understood that my camera was a replacement warranty and the warranty replacement serial number has never been activated. She finds my serial number with the original purchase of a previous file number, activated the serial number of replacement and after a brief support is now send me another replacement aircraft, from one day to the next day, free of charge.

It is regrettable that this model has been nothing else into trouble, but it's good to know that the warranty service is not too difficult.

In the face of "the device associated with this extension or the dial number is not valid" when you use DX80 telepresense phones

Hi team,

We have EX and DX series telepresence as endpoints agent. But DX series phones are facing issue "the device associated with this extension or the dial number is not valid" when checking in the agent. EX works very well. Both phones are properly recorded in CUCM.

Can you please help me out here to solve the problem.

Thanks in advance,

Sisi.

In my case, we tried to do a few different modifications here and there on the DX650 but never managed to do work. Randomly, I was able to connect to the fineness with the DX650 as my camera, then my colleague could not connect to the Finesse with his 9971 as his camera - (keep in mind this was in an environment of model and it was just her and me as agents). Since I saw this strange behavior and doesn't do not sense, we rebooted the server CCX. Once she is back to the top, we were also well able to connect successfully and had not had the problem since.

Thank you

You can; Simply enclose it quotation marks name whenever you use it.

For example:

CREATE TABLE '3-26.
(
'name 1' VARCHAR2 (10)
);

INSERT INTO '3-26' ('1 St Name') VALUES ('FUBAR');

SELECT '1 name '.
"3-26;

Remember, what inside quotes is case-sensitive, so you can't refer to that column as "1st NAME.

Using quotation marks (and capitalizing exactly as expected) is such a pain that most people don't bother.

How to update the table with the number management

Hello

I need as there is a loc_tab of the created table as below,

CREATE TABLE loc_tab
(
Country_ID NUMBER,
country_code VARCHAR2 (3),
country_name VARCHAR2 (50).
State_ID NUMBER,
state_code VARCHAR2 (3),
state_name VARCHAR2 (50).
city_id NUMBER,
city_code VARCHAR2 (3),
city_name VARCHAR2 (50)
);

I inserted records like below,

COUNTRY_ID     COUNTRY_CODE     COUNTRY_NAME     STATE_ID     STATE_CODE     STATE_NAME     CITY_ID     CITY_CODE     CITY_NAME

          IND          INDIA                    TN          TAMIL NADU          CHN          CHENNAI

          AUS          AUSTRALIA               TAS          TASMANIA          BUR          BURNIE

Now, I wanted to update the table such that all ID columns are updated with running number.

Each ID columns should get incremented so that, for Country_ID column corresponding to "India" If country_id is 1, that there must be one for all the lines with the name as "India". Likewise for "Australia".

In the case of State, she also has the same logic with numbers repeated until the very name of the State comes.

For the city, it of course will hold separate ID only because the name of the city will not get duplicated.

This update must be done in the normal way using simple SQL such as no PLSQL don't like looping, etc... is involved.

Here are the contents of the table, and that's how the table should be updated,

COUNTRY_ID     COUNTRY_CODE     COUNTRY_NAME     STATE_ID     STATE_CODE     STATE_NAME     CITY_ID     CITY_CODE     CITY_NAME

I cannot select table jump extensions associated with lost data files?
Hi ~.
I need your help to recover my database.

I use oracle 9.2.0.8 to Fedora 3 with mode-archive.
and I have no backup.

Last night, I have experienced hard drive failure.
I tried the recovery at the level of the BONE, but I lost some data from the tablespace files.

in any case, I wanted to recover my database without the data of lost data files.

then, I published 'drop alter database datafile offline' and
Start the oracle instance.

But, data files were not eliminated from dba_data_files view and
extensions associated with lost data files were not removed from dba_extents view!

Query a selection table containing extensions associated with lost data files.
I have "ORA-00376: file xxx cannot be interpreted at this time" message.

So, my question is that...
HOW CAN I SELECT TABLE WITHOUT EXTENSIONS RELATED TO THE LOSS OF DATA SCANNING FILES?

Thank you.
Hello
Without being in archivelog and without backup, can't make any sort of recovery. This is why the backups and archivelog are so important.

The offline data file command never actually drops the data file. It simply tells the control file now the tablespace of the said is also abandoned. It refreshes not any notice that the files are not supposed to be used or shown more than you.

What documentation is the recovery of the database in the mode NoARch.
http://download.Oracle.com/docs/CD/B19306_01/backup.102/b14191/osrecov.htm#i1007937

Do you need a backup in order to recover the tables being played. Oracle is not have all the features that can currently out / skip missing extensions for you and you can read the data without them.

Performance problem with SQL for recovering data in FACT and Dimension Table

Hello

We have a query that performs very slow when extracting data in FACT and the DIMENSION Table.

SQL and Plan are in the attachment.

Please suggest how this can be improved.

The version of DB is 11.2.0.4

Kind regards

Slow is a very relative term, for about 1 hour is slow for some 1s is slow. So please always quantify your settings.

The first thing caught my eye is done 4 times ia_oasis_tot_prov_cur_d access. Try to isolate which and change it like this and see if it returns the same result.

select case when a.clm_capitn_ia_bil_prov_edw_sk = b.prov_edw_sk then b.prov_id end ben_billing_prov
     , case when a.clm_capitn_attnd_prov_edw_sk  = b.prov_edw_sk then b.prov_id end ben_attending_prov
     , case when a.clm_capitn_ia_pcp_edw_sk      = b.prov_edw_sk then b.prov_id end ben_pcp_number
     , case when a.clm_capitn_ia_ipa_prov_edw_sk = b.prov_edw_sk then b.prov_id end ben_ipa_number
  from edw.clm_capitn_f partition (jan2015) a
  left join
       edw.ia_oasis_tot_prov_cur_d b
    on (
           a.clm_capitn_ia_bil_prov_edw_sk = b.prov_edw_sk
        or a.clm_capitn_attnd_prov_edw_sk  = b.prov_edw_sk
        or a.clm_capitn_ia_pcp_edw_sk      = b.prov_edw_sk
        or a.clm_capitn_ia_ipa_prov_edw_sk = b.prov_edw_sk
       )

If it works this means allows you to reduce certain I/O.

Problem creating hierarchy based on 2 physical dimension tables
I'm having a problem create 1 dimension logic with a hierarchy of exploration, based on two separate physical dimension tables. The errors I get when navigating in the exploring hierarchy is:
"Cannot find coverage source logical table to the columns of the logical" &
"Missing join between the logical tables.

I use OBIEE 10.1.3.4
Here are the details of what I have set up as:

Physical layer:
Table DIM_ORG with the dimension columns:
-dimension_key
-org_total_code
-org_total_description
-org_detail_code
-org_detail_description

Dimension table DIM_DEPT with columns:
-dimension_key
-dept_total_code
-dept_total_description
-dept_detail_code
-dept_detail_description

FACT_SALES table with columns of facts:
-fk_org
-fk_dept
-sum_sales

Physical joins:
FACT_SALES.fk_org = DIM_ORG_dimension_key
FACT_SALES.fl_dept = DIM_DEPT.dimension_key

Business model and the mapping of layer:
I created a logical dimension ORG_DEPT. It contains two sources of logic table (DIM_ORG & DIM_DEPT) and the following logical columns:
-All departments (mapped to dept_total_code)
-Organization (mapped to org_detail_description)
-Organisation number (mapped to org_detail_code)
-Department (mapped to dept_detail_description)
-Department Code (mapped to dept_detail_code)
The logical key of the company is based on the combination of number of organization & Department Code

The hierarchy, I need is: all departments-> organization-> Department so I created the following hierarchy for ORG_DEPT:
-Total level containing: all departments
-Organization level containing: company (defined as logical level key) number & Organisation (als defined the key level drill)
/ Department detail level containing: Department (defined as logical level key) Code and the Department (defined as key level drill).

In the LTS of the ORG_DEPT dimension, I've set levels of content for sources:
DIM_ORG: Level of organization
DIM_DEPT: Level of detail Department
The LTS non - joins inner - came against the associated physical tables.

I created a logical fact table (based on the physical fact table) SALES and joined him on the ORG_DEPT logical dimension table.
In the LTS, level of content for ORG_DEPT is part of the level of retail service. Non - joins inner were aded against related physical tables.

When I create a report in response to test the hierarchy and select only "all departments' I get the value of the returned correct size. When I try to break through to the next level, I get the following ODBC error:
"Could not find coverage source logical table for logical columns: [all of them]." "Please check more detailed level keys are correctly mapped.

When I create a report in responses and select "Every department" and "Sales", I get the correct result. When I try to break through to the next level, I get a different ODBC error:
"Lack of join between the logical tables DIM_DEPT and DIM_DEPT: there must be at least a physical link to join between the underlying physical tables.

All suggestions are welcome!

Thank you!
You have no relationship defined between the Department and org.

You can either:
a. create a table of physical dimension with a composite key of org_id & dept_id if there is a relationship defined somewhere, then to obiee model as you have already done, but in the physical layer on the composite key join
b. model your exisitng as two-dimensional and two hierarchies tables and set up a path of forest favorite between them according to your needs.

Kind regards

Need help with Images associated with berries

`
I'm not sure if this is possible, as I am not a common programmer, but I have a question.
I have a table that generates a random word in a text box, then a second table that generates another word at random in a different text box. What I want is for when a certain word off number one table is generated, a certain image is displayed with it. Here is the code:
var FirstChoice:Array = ['this', 'Do'];
var SecondOption:Array = ["during this operation', 'while doing this'];
generate_btn.addEventListener (MouseEvent.CLICK, getTask);
function getTask(event:MouseEvent):void {}
var randomChoice:Number = Math.floor (Math.random () * firstChoice.length);
var randomTask:Number = Math.floor (Math.random () * secondOption.length);
First_Thing.text = exerciseChoice [randomChoice];
Second_Thing.text = homeTask [randomTask];
}
For example, when I click the button and the first table generates "Do this", I want a chart specific to appear with him. Similarly, if 'this' generates, I want a different graphic to appear specifically associated with this variable.

I hope that this is possible :/ I'm puzzled! I asked for help on StackOverflow; However, their advice did not work. Of course, I only got a response, so I hope that people here can help me out!

var FirstChoice:Array = ['this', 'Do'];

var SecondOption:Array = ["during this operation', 'while doing this'];

var imageA:Array = (mc1, mc2);

var currentImage:MovieClip

function getTask(event:MouseEvent):void {}

var randomChoice:Number = Math.floor (Math.random () * firstChoice.length);

var randomTask:Number = Math.floor (Math.random () * secondOption.length);

First_Thing.text = exerciseChoice [randomChoice];

Second_Thing.text = homeTask [randomTask];

{if (currentImage)}

currentImage.visible = false;

}

currentImage = UIImage [randomChoice];

currentImage.visible = true;

}

Attributes of the update/load (nonkey elements) Dimension table
Hello

Is there a configuration change in DAC or Informatica where I choose to load all dimension during a load tables, regardless of a transaction in the fact table? I have observed that for all these accounts with no corresponding transactions are extracted, but fell to the time they reach the actual dimension table. So in the end goal of DWH, only these unique accounts are presented which have an associated transaction.

I know that we can create a mapping to the in order to include some sort of a flag to DAC thing assuming that the corresponding made base table has also changed and then carry on the dimension data. But is there a simple alternative?

For example, in the GL, we have an account dimension, which has a line details associated with the transaction for each account in the fact table. I just changed the name of the account from A to B. Any changes or updates to the entrance of the line in the FACT table. Now, I run an incremental load. Will be change (new account name) has recognized and more? OR it will bring only when associated with line changes too?

Usually when the dollar amounts do not change, nobody cares, but in our case the customer wants. I googled widely understand incremental loading but cud not get a clear answer to this question. SCD2 plays a role any in this?

Thank you
Dan
If you want to capture the story on a field that is NOT before now, you can activate the Type 2 SCD and then add that field to the ETL in TYPE2 COL DIFF indicator that is used to add the entries of SCD Type 2 during the ETL. If the dimension is activated in Type 2, most of the work is done, it is not too difficult. However, be aware that this can lead to many more recordings volume performance and data to keep in mind that do you this.

Dimension table is associated with N number of fact tables
