When and Why do we need to build a CUSTOM CUBE

Hello Experts, Could some please explain with a scenerio ..
"When and Why do we need to build a CUSTOM CUBE"
Thanks in advance
Bhalout

When and Why:
Custom cube should be think of when the constent cube is either not suitable nor available for a subject area.
If there is a content cube and but does not meet your reporting needs, then the better thing will be to adopt the content one and make changes.

When and Why Do We Need to Create 2 Diff iTunes Libraries?

Hi,
When and Why Do We Need to Create 2 Diff iTunes Libraries?
Thanks.
Ed

There's no fast rule sayng you must, and I suspect most people only use one.
You might want to set up a second library if your first one is so huge that it is slow to operate. Split your media. For example, I don't listen to classical and rock music at the same time and could restart iTunes ffrom a different library when the time came to switch.
I have a few extra libraries. One's for music I organized for a special occasion but don't really listen to myself and don't want it cluttering mine. I also have a special library for my mp3 player (not an Apple model) with its own set of files which match some in my main library but they are tagged differently to be compatible with the player's quirks.
I could also see having a different library for files on an external drive if you have some on your internal drive too. You might, for example, have a bunch of movie files on an external drive that you don't normally need to have plugged in all the time and don't want iTunes giving you a bunch of exclamation marks if are using it to play your music media on your internal drive.

When and why do we need the object 'dimension' created by OWB

Hi
When we generate code for a dimension along with the ddl for the table
a dimension object with a post fix of _DIM is being generated. Do we need to
deploy this. Why do we require this and What is its impotance.
May be this is a basic doubt but will be thanfull if someone can tell me its importance
Thanks
Nanda Kishore

Nanda,
A dimension object has built in definitions of a parent-child relationship between pairs of column sets ("levels" of the dimension hyerarchy). The optimizer uses these relationships with materialized views to perform query rewrite and thus makes the queries more efficient.
For more details, please refer to the Oracle data warehousing guide:

I have windows 7 and I can't sign into ITunes. Message says to turn off compatibility mode to use. How and why do I need to do this?

I have Windows 7. I was previously using Windows 98 when I set up ITunes and developed a library of music and movies. When I try to log in I keep getting a message stating that am using an older version of Windows and that I need to turn off "compatability mode to use ITunes. Where and why do I need to do this?

What are smart mailboxes and why do i need both smart and "normal" ones?

What are smart mailboxes and why do I need both smart and "normal" mailboxes?

Hi Kingoftypos,
Thanks for that clarification. So, now it appears that the ultimate purpose of a Smart Mailbox is to point to all emails that meet the criteria in a single place, so if they are spread among several mailboxes, you will be able to see them all together. Here is an article from Apple that describes it:
A Smart Mailbox displays in one location messages that are stored in other mailboxes, so you don’t have to move messages between mailboxes. The messages displayed by a Smart Mailbox are based on criteria you define, and are automatically updated to include new messages that match your criteria. For example, you might create a Smart Mailbox that displays all messages found in all mailboxes from a specific sender.
If you change a message in a Smart Mailbox, such as marking the message as read or unread, or moving or deleting the message, the change is reflected in the mailbox where the message is actually stored.
So, adam, I would think that, if you had mail going to a lot of different places, and wanted to be able to see a particular set of those in a single place, you would use a smart mailbox. Maybe use the rules to direct your mail to different places to start with, but a smart mailbox to bring a set of common ones all together into a single smart mailbox?
Maybe you have Rules move your Amazon mail to an Amazon folder and your Apple mail to an Apple folder, but then you have a Smart Mailbox that contains any mail that has the word "Receipt" in the Subject line?
Just a thought....
Cheers,
GB

What are Layers? And why do I need them?

WHAT ARE LAYERS? AND WHY DO I NEED THEM?
Layers are an essential part of Photoshop. With Layers you can separate pictures or design elements from each other, as if they are stacked on pieces of glass. With all elements separate, you can move or change them independent of each other.
Layers are used for many tasks, including improving your images' color or tone; merging two or more images in one Photoshop file; and creating Web designs and animations.

WORKING WITH LAYERS - VIDEO 11:16 min.
KEY CONCEPT: LAYER
PHOTOSHOP/ LAYERS BASICS - Reference Guide

After creating the mask and applying adjustment, you can also adjust and change layer mask using selection tools or, the most common way, using brush tools.
To have a more accurate preview of what are you doing, Alt + click on the layer mask thumbnail to show the mask in the image area.
At this point, you will have a layer mask on your screen in large view, so it is easy to fine tune it, but you wont see how that affects your image.
To seean instant preview how changes on layer mask affects the adjustments, use New Window for (name of your image) from Window > Arrange.
Here is a more detailed tutorial on the topic: New Window for.. Command in Adobe Photoshop.

Why is it a shared folder in the music app and why do i need internet to listen to it?

why is it a shared folder in the music app and why do i need internet to listen to it?

Try in order:
- Resetting the iPod:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Restore the iPod from backup via iTunes
- Restore the iPod to factory defaults/new iPod since you may have corruption that is now in your backup
Based on the info you provided it appears you did the restore from backup and sitll have problems. Thus, I would just restore the iPod to factory defaults/new iPod.

What is an Oracle Client and why is it needed

Hi,
I have an application that is using an Oracle database as data source. Application and database is located on two different servers. Now I will move application to a new server and to do this I need to install an Oracle client and install this on the new application server. From my understanding this Oracle client is needed to make it possible for the application server to communicate with the database server. I wonder if someone can tell me more about this Oracle client, functionality, role and why it is needed?
I have been recommended to install the Oracle client 10g version. Where can I download this together with instructions of installation process?
FYI - database used is Oracle 10g EE.

Third-party products (and Oracle's own too) need certain Oracle DLLs in order to connect to the database. This set of files is called the Oracle client. You may also want to learn about tnsnames.ora because you need to edit it in order to use Oracle client to Oracle database.

Query as Web Services!!! What are its uses and why do we need it?

What are its uses and why do we need it.. if other tools like Dashboard and crystal reports and Webi can connect to universe and create reports and Analytics...

Hello Rajsan Madhavarajan
Query as a Web Service (QaaWS) is a SAP Business Objects (BOBJ) client-side tool that allows users to create and publish Web Services that can be made available over the Web. Once these web services are created and published, they can be consumed like any other standard Web Service in software applications including Xcelsius and Crystal Reports. But first we have to understand what exactly is a Web Service.
Web Service
A Web Service is a software system that supports interoperable interaction over a network from one computer or machine to another but is more commonly defined as a client and a server communicating data over the Web using the HTTP Protocol. Using Web Services along with Business Objects allows a live connection of data to be used in applications such as Xcelsius and Crystal Reports through a semantic layer called a Universe.
Query as a Web Service (QaaWS)
The two main components in QaaWS are the Client Tool and the Server. The QaaWS Client Tool gives the end user an easy to use wizard that allows them to create Universe queries and publish them as Web Services. Once the QaaWS is published, any user can securely access the data that the Web Service contains as long as they have access to that server. Have a look on image below that shows the information flow to and from the server via the client.
Advantages to QaaWS:
Very easy to use and intuitive interface Familiar look and feel for people who have used Web Intelligence
Leverages existing Business Objects Universes Shares metadata with Web Intelligence, Desktop Intelligence and Crystal Reports
Maintains Business Objects Enterprise Security
Allows live data feeds to be incorporated into Xcelsius Dashboards and Crystal Reports

Vectors gone? When and why?

I have read in a couple of posts that Vectors are "legacy" and may not be around forever. Can anyone shed light on the when and why of this? I am relatively new to JAVA programming but I do have a bunch of applications out there that use Vectors. I personally found them very easy to work with.
Thoughts?

Wow! I can't wait for Java 2.0! (Please read heavy sarcasm.)
Speaking of rumors, let's not start spreading any rumors that the Java group at Sun has actually started to talk about -- let alone publicly announced -- that a 2.0 version is in the works; 1.5 sounds right to me.
I know that you can get almost the same functionality out of a List that is returned from the Collections.synchronizedList(List) method as you can out of a Vector, but Vector is by no means a deprecated class. (We should try to be careful about the casual use of meaning-laden words.) pengjuc is right that a lot of Swing (and non-Swing) classes such as JTable rely on Vector; the mere rewrite to replace all the Vectors with ArrayLists would probably require a Java release all on its own (and whose to say that ArrayLists are really all that, anyway?). Moreover, Vector is part of the public API of many classes and to deprecate it would throw a lot of developers into a tizzy because it would potentially break the ability of their applications to upgrade to a new version of Java. There is nothing inherently wrong with Vector -- it performs as advertised -- and pengjuc is right again that the performance differentials are minute over small object collections.
In response, again, to dubwai, there's a difference between using Vectors as a developer and having them included in the J2SDK. If you don't like them don't use them, and if you don't like them in other classes, rewrite those classes to your taste. Personally, I think you either have to take what you're given, do it yourself, or get involved in the process.
Good luck, All!
Shaun
