Well, Hyperion is a database that allows the user to access data very quickly compared to the rest of the databases. This company was actually bought by Oracle in the year 2007 and then has made significant improvements to the product.
For Hyperion, we have a fancy name as well which is nothing but Business Intelligence, usually called BI. The primary use of this is to support and provide value-add services for businesses while taking decisions.
So most of the time the BI system is actually classified as Decision Support System (DSS). So this aids the organization-level process improvement and efficiencies. All the data is gathered and based on the suggestions the organization will be in a good position to make decisions.
Hyperion Planning is nothing but a budgeting and forecasting platform where it was previously owned by Hyperion Solutions Corporation. But all of this is executed under Oracle as they have bought this company in the year 2007. So Hyperion Planning actually uses an Essbase ( Essbase is nothing but an s multidimensional database product sold by Hyperion) and calculation engine, repository for harvesting business logic.
Further to access all of these services, they have provided a web-based user interface.
With the help of this software, the user will be able to add planning and forecast-related data to the actuals. With the use of Web forms, the users will be able to play around with the data by using Excel SmartView Tool.

Ans:-The HFM stands for Oracle Hyperion Financial Management. As the name itself states that it is a financial management-related tool. It is a web-based tool that helps the users to deliver financial consolidation at the global level and on top of it provides analysis and reporting abilities as well.

This tool can be easily and quickly installed without another hassle and it is integrated directly into the Oracle and non-Oracle-based transaction systems. They provide top-notch reporting needs where the organization's top tier can enjoy the tailored information easily.

1. Application log
The attribute is nothing but a group of members that are based on the associated attributes. Using these attributes you will be able to perform calculations and also use calculation functions. A dimension is nothing but a classification of the member.
For example: Let’s consider a sample database where the product dimensions are nothing but attributes where they have information like size, package type, flavor, etc. So adding up these attributes together to the dimensions will help them to retrieve the information something like this below:
Diet Coke with 10 Oz with bottles. This type of information is used for generating reports.

The report performance is impacted by Attribute dim, as follows:
1. The report performance is at high risk because all the attributes are calculated dynamically as per their reference. If we have a very large number of attributes then the report performance could go down drastically.
2. The report performance will be compromised if the data is loaded in this fashion. While loading the data if the selection criteria and rejection criteria are applied for the same record. During this scenario, the file will be rejected.

Within the Hyperion Essa database, we cannot use both ASO and BSO databases for a single application. While creating an application the user has to select either ASO database or BSO database.
So based on the selection only the users will be able to create the database. Also, the classification is at the application level and not at the database level.

The acronym ASO stands for Aggregate Storage Option. The use of ASO is as follows:
1. This is used only if we have a large number of dimensions
2. Out of the dimensions, most of them are limited
3. Also, we cannot write back into the ASO database
The acronym BSO stands for Block Storage Option. The use of BSO is as follows:
1. Within this database, the dimensions are less and dense.
2. We can write information back to the BSO database, that’s the reason they are used for planning applications
No, you cannot build dimensions directly from the data sources without using rule files
So, we use build rule files to automate the entire dimension creation process with thousands of members involved.
The top 3 methods that are primarily used for building dimensions are as follows:
1. Generation references
2. Level references
3. Parent-child references
UDA is not at all related to the database size, it doesn’t have any impact on the database size because UDA doesn’t require any additional storage space.
The Attribute dimensions provide a flexible approach when compared to UDA’s.
In Attribute calculations dimensions include Five members, they have defaulted to the following names.
1. Names sum
These dimensions are automatically created and are calculated dynamically.
The UDA values are not at all displayed in the reports and they don’t have any impact on report performance.
The extensions are listed as follows:
The primary role of providing services is mainly to communicate between Essbase and the Microsoft Office tools.
Well, once the application is created in Unicode mode it will be left as it is for its life. We cannot change the application from Unicode mode to non-Unicode mode. This option is not possible.
Well, if we have a single processor then we will be using a serial calculation. But, if we have a parallel calculation then we will have multiple processors. All the multiple processors are actually divided into tasks and then finally into threads and finally execute on different processors.
