Transcript of The Process of analysing

Analyzing is the information process that Transforms data into information.transforming data into information is a central aim of all information systems. they all collect data transform it into information this information
Searching/Selecting data
Most software applications search and select data based on criteria. In many software applications the user can directly initiate a search to find particular data. In many software applications searching take place as an integral part of larger process in fact many analyzing processes include various simple and complex searches for example to create a pie chart requires data to be grouped according to various categories.


Sorting
Analyzing information processes involves sorting data either sorting into alphabetical or numerical order or even sorting different categories. When data is sorted it is easy to understand. Sorting transforms data into information. All digital data of media types is represented as binary numbers therefore sorting digital data is performed numerically.

Modeling/simulations
A model is used to represent word system
therefore modeling is the process or act of creating a model for example the plans for building a house in this case a scale drawing with various specifications detailing the materials and method of construction. A simulation alters various parameters of a model often including time to produce imitations of a systems operation. Computer modeling and simulation are analyzing tasks that utilize computer resources to represent something mathematically and to produce meaningful information.

The Process of analyzing
Analyzing is the information process that transforms data into information. Transforming data into information is a central aim of all information systems. They all collect data and transform it into information is this information is then used to increase knowledge of the systems user.
Software features for Analyzing
All software performs analyzing tasks. There are a variety of different analysis features which are present in numerous software applications. The efficiency of analyzing processes is determined by the organization of the data such as:
Software requirements
Non-Computer procedures in analyzing
Digital data that has been organized improves the efficiency and accuracy
of most analyzing tasks however there are still many information systems that use or don't use computers for example a manual filing system used in a library.
Searching manual filing systems
To search for particular data within a manual filing system is time consuming even when the files are sorted based on the field being searched. Files can be viewed by a single person at one time and after use has to be returned to its correct position. If files are not sorted on the field being searched the time take to perform the search is increased. Many business and organizations continue to use manual filing systems.
Some reasons include:
Cost- hardware, software and data entry and training costs must be met upfront when implementing a new computer based information systems.
Volume of data- most business start up with small amount of data as a consequence time taken to manually analyze this data is not significant
Training- to use a computer based filing system requires knowledge and understanding of the hardware and software.
Nature of the data- Most computerized info systems require data to be organized in structure. If additional field are needed the structure of the entire system must be altered

Hardware requirements
Hard Disk
In terms of the analyzing process the best measure of secondary performance would be one that records the time taken for the actual data required by a particular analyzing process to be read and successfully placed into RAM.
RAM (Random Access Memory)
RAM is a form of computer data storage. A random-access device allows stored data to be accessed directly in any random order. In contrast, other data storage media such as hard disks, CDs, DVDs and magnetic tape.
CPU (Central Processing Unit)
CPU is the number of bits that can be processed simultaneously. different CPU designs are suited to different types of processes A computer can have more than one CPU this is called multiprocessing. Some integrated circuits can contain multiple CPU's on a single chip those are called multi-core processors.
social and ethical issues
unauthorized analysis of data
Organizations that hold data on individuals are required to disclose how such data will be used.such disclosure must contain a clear indication of h ow an individual can choose to be excluded from the process

data incorrectly analyzed
There may be errors with the process e.g. a query may exclude records that should actually have formed part of the data. the result will end up being incorrect.
linking databases for analyzing
linking together multiple databases so they can used to formulate new information that was not present in any of the individual source database .this is also known as "data mining". data mining is usually applied to large databases in attempt to find new patterns
