Dimensions and facts related to all BI Apps Financials Star Schemas

I am kind of new to BI Apps and was wondering whether there is a list of tables/dimension names/ facts that constitute each star schema in Financial Analytics?
I know there are star schemas like AP Aging, AR Aging, AP Transactions, AR Transactions and so on.
How do I get the OBAW dimension and fact table names that are in each of these star schemas?
Oracle BI Apps presentations take me only to the business name of the dimensions and does not give me the original dimension name used in OBAW.
Thanks in advance!

Hi Sid
I am in Data Model Reference that you have mentioned. All the star schemas over here are pictures and are not searchable. Also, the ppt that Oracle gave us just says AP Aging as the fact name and I dont know how I can find the fact table corresponding to that.
If someone can point me for that piece of work, I will go though the star schema pictures in the documentation and find relevant dimensions and facts.
Is there any naming convention that we can use like W_APAging_F table or something like that??
Thanks in advance !

Foreign keys in SCD2 dimensions and fact tables in data warehouse

Hello.
I have datawarehouse in snowflake schema. All dimensions are SCD2, the columns are like that:
ID (PK) SID NAME ... START_DATE END_DATE IS_ACTUAL
1 1 XXX 01.01.2000 01.01.2002 0
2 1 YYX 02.01.2002 01.01.2004 1
3 2 SYX 02.01.2002 1
4 3 AYX 02.01.2002 01.01.2004 0
5 3 YYZ 02.01.2004 1
On this table there are relations from other dimension and fact table.
Need I create foreign keys for relation?
And if I do, on what columns? SID (serial ID) is not unique. If I create on ID, I have to get SID and actual row in any query.

Are you still designing your system? Why did you choose NOT to use a Star schema? Star schema's are simpler and have some performance benefits over snowflakes. Although there may be some data redundancy that is usually not an issue for data warehouse systems since any DML is usually well-managed and normalization is often sacrificed for better performance.
Only YOU can determine what foreign keys you need. Generally you will create foreign keys between any child table and its parent table and those need to be created on a primary key or unique key value.

I have no idea what that means. There isn't any way to tell from just the DDL for one dimension table that you provided.
It is not clear if you are saying that your fact table will have a direct relationship to the star-flake dimension tables or only link to them through the top-level dimensions.
Some types of snowflakes do nothing more than normalize a dimension table to eliminate redundancy. For those types the dimension table is, in a sense, a 'mini' fact table and the other normalized tables become its children. The fact table only has a relation to the main dimension table; any data needed from the dimensions 'child' tables is obtained by joining them to their 'parent'.
Other snowflake types have the main fact table having relations to one or more of the dimensions 'child' tables. That complicates the maintenance of the fact table since any change to the dimension 'child' table impacts the fact table also. It is not recommended to use that type of snowflake.
See the 'Snowflake Schemas' section of the Data Warehousing Guide
http://docs.oracle.com/cd/B28359_01/server.111/b28313/schemas.htm

Snowflake Schemas
The snowflake schema is a more complex data warehouse model than a star schema, and is a type of star schema. It is called a snowflake schema because the diagram of the schema resembles a snowflake.
Snowflake schemas normalize dimensions to eliminate redundancy. That is, the dimension data has been grouped into multiple tables instead of one large table. For example, a product dimension table in a star schema might be normalized into a products table, a product_category table, and a product_manufacturer table in a snowflake schema. While this saves space, it increases the number of dimension tables and requires more foreign key joins. The result is more complex queries and reduced query performance. Figure 19-3 presents a graphical representation of a snowflake schema.

Improve Performance of Dimension and Fact table

Hi All,
Can any one explain me the steps how to improve performance of Dimension and Fact table.
Thanks in advace....
redd

Hi!
There is much to be said about performance in general, but I will try to answer your specific question regarding fact and dimension tables.
First of all try to compress as many requests as possible in the fact table and do that regularily.
Partition your compressed fact table physically based on for example 0CALMONTH. In the infocube maintenance, in the Extras menu, choose partitioning.
Partition your cube logically into several smaller cubes based on for example 0CALYEAR. Combine the cubes with a multiprovider.
Use constants on infocube level (Extras->Structure Specific Infoobject properties) and/or restrictions on specific cubes in your multiprovider queries if needed.
Create aggregates of subsets of your characteristics based on your query design. Use the debug option in RSRT to investigate which objects you need to include.
To investigate the size of the dimension tables, first use the test in transaction RSRV (Database Information about InfoProvider Tables). It will tell you the relative sizes of your dimensions in comparison to your fact table. Then go to transaction DB02 and conduct a detailed analysis on the large dimension tables. You can choose "table columns" in the detailed analysis screen to see the number of distinct values in each column (characteristic). You also need to understand the "business logic" behind these objects. The ones that have low cardinality, that is relate to each other shoule be located together. With this information at hand you can understand which objects contribute the most to the size of the dimension and separate the dimension.
Use line item dimension where applicable, but use the "high cardinality" option with extreme care.
Generate database statistics regularily using process chains or (if you use Oracle) schedule BRCONNECT runs using transaction DB13.
Good luck!
Kind Regards
Andreas

I have upgraded my iTunes for Windows and I have lost all my apps and music

I have upgraded my iTunes for Windows and I have lost all my apps and music.
Although i signed in with my iTunes account, i can see only 5 apps (that i downloaded in the last 2-3 days), although on my iPad and iPhone i have more than 100 apps.
If i connect my devices to iTunes, the syncronisation will be made the other way, from iTunes to iPhone/iPad, so i will lose everything.
1. How can i restore these apps from the iCloud back-ups from my devices to my iTunes? Or any other method possible?
2. If you can also give me a suggestion about how to find my music playlists, that would save me from a lot of useless work on creating them again.
Thank you!

Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
In the unlikely event that all the media has been inexplicably and permanently removed from your computer, see Recover your iTunes library from your iPod or iOS device.
When you get it all working make a backup!

Add Audit Columns to the Dimension and Fact tables (Created & modified date Time)

Hi All,
I am new to SSIS , I have to Add Audit Columns to the Dimension and Fact tables (Created & modified date Time) of the package.
Please let me know the best and easy way through which I can implement the same.
If possible suggest some real time example or link where I can find the same
Regards,
Vipin jha
Thankx & regards, Vipin jha MCP

You can simply use ALTER TABLE ADD.. syntax to add the columns if the tables already exist.
You can generate a single script for all tables using INFORMATION_SCHEMA.TABLES view
You can make then of NOT NULL type and set the default value to GETDATE()
In addition you can also have a Audit Trail trigger for UPDATE to make sure Modified date gets updated correctly on each update if not passed explicitly.

How to load data to dimensions and fact table is it simialr to sql server

How to load data to dimensions and fact table in a data ware house environment, is it simialr to sql server, oracle?
Never migrated or loaded data to datawarehouse server.
I have an interview and am really confused if they ask anything related to the dataware house side elements.
Coudl you please if you don't mind provide me some steps and dimension and fact table info, an example only.
Atleast for my knowledge.
Thank you very much for the helpful info.

Loading dimensions and facts (Please verify the design is correct)

Hi,
I am very new to OWB and Datawarehousing, please find the following approach and let me know if its correct or not.
I have the following source tables,
1. Sales -->store_id,Product_id,Sales_date_Time,Unit_sales,Amount_sales
2. Product--> Product_id,Product_name,Product_category_id
3. Product_Category --> pc_id , pc_name
4. Stores -->store_id,store_name,city_id
5 City --> city_id , state
The above tables are normalized,
Now i have created Dimensions , and Fact (Please check whether its correct or not)
1 . Product_Dimension ->Product_key, product_id,product_name,pc_id,pc_name
2. Time_Dimension --> Time_key, ...Can be loaded from the Excel sheet provided (This is what people do here in my company)
3. Stores_Dimension --> Store_key,store_id,store_name,city_id,state
4. Sales_fact -->Product_key,time_key,store_key,Unit_sales,Amount_sales,sales_date
If the above design is correct, then i will create the following mappings
1. Map_Product --> loading product and product_Category from source
2. Map_Time --> loading thru SQLLDR directly
3. Map_Stores --> loading stores and city from source
Once the above mappings completed ( loading all the dimensions)
map_sales_fact --> loading from map_product, map_time, map_stores...
But if here if you closely observe Sales_Fact table, it has columns like unit_sales,amount_sales and sales_date. How do i load these as i dont have them in any dimensions,
Please help , please reply me if you need any clarifications.

Hi,
first of all, there is no need for the column sales_date in your fact table. Use the time_id for date reference.
In your dimensions, use surrogate keys that are generated in your dwh. Do not use ids from your source as surrogate keys!
You may use the ids from the source as business keys, if the names are not unique.
Load your fact table from source table sales. Join all dimensions to get the surrogate keys of product, store and time.
Write the surrogate dim keys into the fact table along with unit_sales and amount_sales.

Carsten.

Hello i just came back from the apple store and they had to restore my phone and i just downloaded all my apps and music back but my photos that are on icloud i only got 80 out of 768 back. what do i do to get all of them back?

hello i just came back from the apple store and they had to restore my phone and i just downloaded all my apps and music back but my photos that are on icloud i only got 80 out of 768 back. what do i do to get all of them back?

If you tried to restore to your iCloud backup and your photos didn't fully restore, first go to Settings>iCloud>Storage & Backup and make sure it isn't still in the process of restoring.
If the restore is complete and all your photos weren't restored, all you can do is try restoring the backup again. You might try the solution posted by ezjules in this discussion: https://discussions.apple.com/message/19518589#19518589. This involves opening the photos app after the phone restarts and you provide the passwords for your Apple IDs, then leaving it open for the remainder of the restore process.

I recently bought an ipad 2 and wanted to use all the apps on my iphone4 on my ipad but have been charged when I use my apple id. What should I have done to share the apps?

I recently bought an ipad 2 and wanted to use all the apps on my iphone4 on my ipad but have been charged for the first app I downloaded when I use the same apple id. What should I have done to share the apps and should I have been charged? 2 months ago when I got a new iphone, i was told in order to get all my apps back as I hadn't backed up my files, if I used the same apple id I would 'purchase' the app, but then would not be charged as apple would recognise that I have already purchased the app. That worked, but when I did the same thing on my ipad 2 using the same apple Id, I was charged... what should I have done and is this right as I thought the whole point of having multiple apple devices was I could share apps between devices. please help! thanks.

Using the same Apple id and Password you should be able to download purchased apps without being charged again.
I download to an iPad/iPad2/iPhone3 & iPhone4 with no problem.

All of my apps are in iTunes AND on my iPod Touch. in iTunes it the checkbox next to sync apps is UNchecked. should i check the box and have to reorganize all my apps or leave it "un-synced"?

all of my apps are in iTunes AND on my iPod Touch. in iTunes, under my iPod, the checkbox next to 'sync apps' (in the Apps page under my iPod) is Unchecked. if I check it, all my apps will be all over the place and I will waste hours trying to get it back to the way it was. I don't really have a reason to check the box but I don't know. should I check the box and have to reorganize all my apps or leave it "un-synced"?
by "un-synced" I mean how it is on my iPod and iTunes at the same time but its not synced

You should ALWAYS make sure that everything is on your computer and backed up, most especially before any update. The iphone is designed to be synced to your computer regularly.
If you have failed to do this, then you need to redownload:

PES 2012 is no longer available in the US App Store and only on the British App Store currently.

That (an app no longer available) happens sometimes.
Your only way is if you have the appt on your computer such as in the recycle bin/trash or in a computer file backup. In that case move it to your iTunes library and sync.

1. Close all inactive apps in the Task Bar. Double-click the Home button and hold apps down for a second or two and tap the minus sign to close app.
2. Try a reset. Hold the Sleep and Home button down for about 10 seconds until you see the Apple Logo

When an iPhone updates, it wipes the whole device clean and then reinstalls the software and then the backup. Obviously you didn't create/couldn't create a backup either via iCloud or iTunes. You can get your apps back when you go to App Store>Updates>Purchased and download the apps you want.

Many to Many relationship betwee dimension and fact tanle

Hello Gurus,
I have a little question about many to many realtionship between fact and dimension table. The situation is as follows.
Consider there is a fact table F1 and two dimension tables D1 and D2. D1 is joined to F1 with 1 to many relationship. D1 is joined to D2 with again one to many relationship ( Note: D1:D2 = 1:N and D1:F1 = 1:N). I am able to model this by merging D1 and D2 into one dimension table in BMM layer by adding them as logical table sources and creating logical table source join. I have built simple reports and the data returnned is fine. However, I would just like to know what could be the drawbacks of such a model.
We have many other dimesions joined to the fact table and users have access to the answers that means they would could what ever report they feel like. Hence, would just like to know in what cases this model could break which means reports would give wrong data because of a many to many relationship between one of the fact and dimension table.
Thanks in advance.

Hello Copter,
Even I had modeled it by reading this link before. In the situation explained by me dimension D1 is doing the job of table Rules ( as explained in link). The model is fine.
However, my point is to undersatnd in which scenerios this model will break. As already explained, the fact table is joined to various other dimensions, there could be situations in which users select columns from various dimensions and facts randomly.
Hence, which are the scenerios where I might get erroneous counts of meassures. Further, if someone feels this model is correct and would not break in any scenerio then please reply.

Dimension and Fact out of Daily Extract File

Hi Folks,
We have a third party vendor which provides us with a daily extract of data in an excel file with about 40 columns. Some of the columns are a typical detail info like "State Name", "Payer
Name" etc. and some are numerical columns like "Billing rate", "Amount Paid" etc.
Now for long term reporting I want to setup a proper datawarehouse with Dimension and Fact Tables. The issue is that the third party vendor is not giving us access to the database source of these excel extracts. So, If I want to design a Dimension
like Dim_Payer, I have only those Payer which are available in the daily excel extract file.
I was thinking of doing a reverse ETL process to load Dimension and Fact Table. So I read the daily excel extract file for unique Payer names and then load the Dimension table with unique keys for Payer. Going forward I only add new Payers. I then load the
Fact tables with these keys.
Let me know if my approach has any issues.
Thanks!

The approach looks fine.
What you could do is to have a SSIS package using data flow task. In it use a excel source and have a set of lookup tasks to see if payer, state etc exists and link the no match output to OLEDB destinations to insert missing values to the table. Finally
have a data flow task to insert data to fact table after having lookups with relevant dimensions to get the reference ids.
