Granularity refers to the level of detail of the data stored fact tables in a data warehouse. High granularity refers to data that is at or near the transaction level. Data that is at the transaction level is usually referred to as atomic level data. Low granularity refers to data that is summarized or aggregated, usually from the atomic level data. Summarized data can be lightly summarized as in daily or weekly summaries or highly summarized data such as yearly averages and totals.

1) Input is when the data is entered into the computer: There are 3 stages involved when imputing data; they are collection, verification, and coding. Collection collects the data and assembles it. The verification checks whether the data being processed it exact and complete. Coding means translating the data, in order for it to be used into machine readable form. 2) Process - The data is processed and organised. 3) Output is when the data which had been processed is presented as a document etc. Answer:
Data processing can be likened to the manufacturing process. In manufacturing,raw materials are processed, or made into a finished product. The raw materials maybe considered "input" to the processing machine. The finished product is "output." Inthe electronic computer, data are the raw material or input to the computer. Thefinished product, or output, is usually a printed report or an updated file containing datathat have been processed or manipulated in some way. The three functions (or stages)of data processing are: input, process (or manipulation), and output. Input involvescapturing data and getting it into a farm understandable to the computer. Processingencompasses the various steps taken by the computer to manipulate the data andprovide information. Output makes the computed results of processing available for usein decision-making

The intention is: data in data warehouse is non updatable
But there exist some exceptions of the non-update rule which may be allowed by data warehouse organisation. Such cases may be:
- error correction of wrong data
- enhancement of missing data
- restructuring (parts of) data warehouse data(base) design
- ...
One leading idea beyond data warehousing resp. one purpose of data warehousing is to enable controller and other users to observe resp. monitor time variant data (e.g. revenue of a product during the last 24 months). It depends on the quality standards whether the above listed exceptions are allowed or not.

Knowing how to recover data is not so easy. Firstly You need to know the hard drive structure. These are some steps for data recovery format...
Hard drive divided in to 2 parts .
1. System Area
2. Data Area
System area further divide in to 4 parts :
1. Root
2. MBR ( Master Boot Records )
3. FAT 1 in case of FAT File System ( Contains Addresses of Data )
4. FAT 2 ( Copy of FAT 1 )
Data Stored In Data Area.
Now how can we recover data from hard drive?
Whenever we delete any file or images or anything which is stored in data area the address of FAT 1 is deleted from the corresponding data means reference is deleted form the FAT 1 but data still intact in Data Area.
When we install any data recovery tool like stellar phoenix to recover that data than this data recovery software recover only the reference from FAT 2 because FAT 2 is the copy of FAT 1 .
Address is deleted from FAT 1 not from FAT 2.
So data recovery software find that address from FAT 2 and your data is recovered ...

The broad field of study called data management is, in essence, the managing of data that is a valuable resource to any business or organization. The Data Management Association (DAMA) is one of the largest organizations that deal in specialization of the field, within which there are many varying topics. These topics include areas such as database administration, data modeling, data mining, data movement and data warehousing.
Data Modeling
Data modeling is a specialization of data management which involves organizing collected data via the use of a structure created specifically for this task. The data is organized in such a manner as to make it easily accessible so that it can be efficiently stored and subsequently retrieved for making analysis and reports.
Data Warehousing
The data management specialization called data warehousing involves the effective storage of data in a manner that makes it efficient to use and access. While different types of organizations use different means of data collection, many of these organizations still use their data in the same manner. They may use it for analysis purposes, to create reports, or to help them make sound business decisions. For large companies, data warehousing may be used to organize the data of each office or department individually. In smaller companies it may be used for creating a single database which encompasses all of the organization’s data in one place.
Data Movement
Surprisingly, the movement of data requires a great deal of somewhat complicated logistics. Data that is collected must then be accessible to the end user. This process involves making sure that all hardware and applications used in the collection and movement processes are synchronized and compatible.
Database Administration
The process of data management involves a very essential function called database management. Database administrators are employed by companies to manage every aspect of the database environment. They are endowed with the responsibility of ensuring that the system performs and functions properly. They develop and test any needed applications and maintain the security, availability and recoverability of the database.
Data Mining
Trends, patterns and relationships that are evidenced by a collection of data can be discovered through a process called data mining. When a business desires to create growth or profit, this type of data management is used to sift through large amounts of information to reveal specific information.
All of these areas of data management work in conjunction. They are used to collect, store and analyze information, and then format it so that specialists can have the opportunity to make informed decisions.
