Ans:all the above

30) What are differences between information design tool (IDT) and universe design tool (UDT)?
  • IDT is the new tool introduced in BI 4. Concept is same as UDT, but presentation is different.
  • IDT (New Universe Designer in Business Objects) = combination of Business View Manager + Universe design tool + Data Federator
  • IDT is the new tool introduced in BI 4. Concept is same as UDT, but presentation is different.
    • In IDT, they have Data foundation layer (instead of structure pane) and Business Layer (instead of Class n object pane). First of all, a project is created, then a relational or OLAP connection, then data foundation and then business layer. Then the universe is published as .unx
  • We have structure pane and class n object pane in UDT. 
    • UDT it is not possible.
  • They have introduced the concept of ‘views’ in Data Foundation Layer. If you have many tables to be used in the universe, it would be difficult to manage joins and structure. So you can create multiple windows.
    • For ex., one view or window would be related to client and all the related tables. Another window could be related to product and related tables, and another could be related to FACT and the main dimension tables. The master view would be the union of all these views.
  • In UDT, you can add a table any time and then can drag it to object pane to create objects automatically.
    • In IDT, automatic classes and objects are created only once when you create the Business Layer for the first time. After that, if you add any table, you have to create objects based on it manually.
  • Identifying loops and creating contexts is not as clean in IDT as in UDT.
31) What are differences between UNV & UNX?

- Supported by Webi ONLY
- Single Data source
- Supported by Webi, Dashboard, Crystal Enterprise & Explorer
- Connect to multiple data sources within ONE UNX

A. as users will rarely use it as selection attribute
B. cannot use it as attribute selection
C. Rarely will user use attribute as condition

Ans: don't know (but you can reject above options)

34) Adaptive Processing servers
Ans: It is used for refreshing a report

35) Operator is not a part of combined query in Web Intelligence 4.0 : Difference
36) Adaptive Job Server - To schedule a report
37) Scope of Analysis: Scope of Analysis determines the additional objects to be included in the query so that the data will be available in drill mode. Before you can drill, you must use Scope of Analysis to select the objects to be retrieved in addition to those that were placed in the Result Objects.

38) Calculation Mode of Rank Functions : Count, Percentage, Cumulative Sum, Cumulative Percentage.

a) Cardinality b) Joins c) All of the above.

Ans: All of the above.

53) Currently Universe is using a DB, if you want to connect to Sybase then what happens?
Ans:  Below could be a checklist for you:

1. Make sure all tables with all used columns (used in report) have been created in new database.
2. Referential Integrity is at place.
3. The database user used to create connection has same privileges which you had in old reporting database.
4. Once new reporting database is ready, refresh universe structure and check if there is any change?
5. You also need to make sure the syntax used in the universe is as per new reporting database. For example: If I am shifting my reporting database from Oracle to Teradata, I will have to replace nvl() function with coalease() function wherever I have used in object definitions.
6. Once done, run integrity check and check if all joins and columns are in place and everything is parsing correctly.

Cloud Computing - Mid Sem Solution

Note: We have tried solving the question paper in a very short time span as per our understanding and the study material we had. Feel free to contact us through comment box or through email if you have some descriptive answer.

Q1. Answer the following questions in brief                                   
A. What are the two ways by which public cloud helps the customers to reduce their IT costs?
  1. Flexible billing models enable customers to pay only for what they use.
  2. It reduces the capital expenditures required for setting up the infrastructure.
 Practice Question - What are the components of a cloud computing environment?
 Answer: client, application, platform, infrastructure, server

B. What are the two limitations of SKI Virtualization?
  1. It is not possible, for instance, to run different versions or even different patch levels of a particular operating system on the same machine. 
  2. Whatever versions exist in the host, that same software will be provided in the guest. SKI also sacrifices the security and reliability provided by other virtualization  methods. 
C. A company interested in cloud computing is looking for a service provider who offers a set of basic services such as virtual server provisioning and on-demand storage that can be combined into a platform for deploying and running customized applications. What type of cloud computing model fits these requirements?
Answer: Infrastructure as a Service.

D. How can a software development company leverage the PaaS cloud computing delivery model?

Q2. Answer the following questions appropriately.
A. What is 3 - 4 - 5 rule of cloud computing?
Answer: This 3 - 4 - 5 rule stands for:

3 cloud service models
4 deployment models
5 essential characteristics of cloud computing infrastructure

RULE 3 - Cloud service models:
IaaS (Infrastructure as a Service):
The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications.
The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls)

PaaS (Platform as a Service):
The capability provided to the consumer is to deploy onto the cloud infrastructure consumer created or acquired applications created using programming languages and tools supported by the provider.
The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations

SaaS(Software as a Service):
The capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., webbased email).
The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user specific application configuration settings

RULE 4 - Deployment models:
Private Cloud (Single Org)
The cloud infrastructure is operated solely for a single organization. It may be managed by the
organization or a third party, and may exist on-premises or off-premises, Also called as “Enterprise Cloud”

Community Cloud (Multiple Org)
The cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, or compliance considerations).
It may be managed by the organizations or a third party and may exist on-premises or off premises.

Public Cloud (For Public)
The cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services, Also called as “Internet Cloud”

Hybrid Cloud
The cloud infrastructure is a composition of two or more clouds (private, community, or public)
Leasing public cloud services when private cloud capacity is insufficient, Also called as “Mixed Cloud”

RULE 5 - Characteristics:
On-demand self-service:
Users can provision servers and networks with little human intervention.

Broad network access:
Any computing capabilities are available over the network. Many different devices are allowed access through standardized mechanisms.

Resource pooling:
Multiple users can access clouds that serve other consumers according to demand.
Cloud services need to share resources between users and clients in order to reduce costs.

Provisioning is rapid and scales out or in based on need.

Metered or measured service:
One of the compelling business use cases for cloud computing is the ability to "pay as you go“, where the consumer pays only for the resources that are actually used by his applications.
