At the beginning of the scoping article, we talked about data and information are very important in education, business or even politics. But, how able to store the vast amount of these data and information? Therefore, we need a hardware device that can store these data and information. That called as Safe-keeping Device. Now, we know the importance of data, so we have to maintain and back up these data and information as well. For these purposes, we use storage area device. Because a few of storage space devices are a nonvolatile medium that is data is retained even though the storage area device is not linked to electrical power. In addition, storage device must be allowing long lasting store these data and information for a particular company such as Airline Company. Airline Company must store customer's information for later use even although customer who is consumes only one time. Storage space devices come in various varieties and use different materials, each with talents and weaknesses. But, how to evaluate each storage area devices? The next four points signify what is that needs to be considered when assessing safe-keeping devices.
Cost, that exactly is refers to how much we buy the storage device.
Capacity is the quantity of data or information that the safe-keeping device can hold.
Access acceleration is the amount of data or information that can be stored or retrieved per time device.
Access setting is identifies the business of data or home elevators the storage space device, either arbitrary or sequential.
Thus, storage area devices differ in the technology they use to keep data and in their physical structure. So, first we will introduce types of storage devices.
When we talk about storage space devices, there are many types and different types of these storage space devices. Quite simply, we divided two types of storage area devices. Among storage area device is the primary storage; a different one of storage is the supplementary storage.
The first one we discussed is the principal storage device. The principal storage can also called as main storage or internal recollection. The primary storage space just holds ram for short durations of times when the principal storage area device is connected to electrical energy, which called as volatile medium. Kind of the volatile medium is erasable. That mean is data or information just stored in the principal storage when the power of primary storage area device is on. But, when the power is switched off will leads the items of data or information in the recollection get erased. Such as for example random access storage (RAM) and cache, they are simply two examples of the primary storage space device. But, the Memory also can vary types as a version for the RAM is the NV RAM. This is of NV identifies the nonvolatile memory space. This sort of the ram will discuss in the following part.
Next, we mentioned a different one of storage area is the supplementary storage. The secondary storage also can called as auxiliary safe-keeping or external memory. The secondary storage space that is clearly a nonvolatile medium. The supplementary storage can store data or information entirely in the storage device. Which means that is the articles of data or information even can be found even if the power of secondary storage space device is should go off, or even though there's a power failing and the contents of data or information also continue to be intact. Therefore, the secondary storage device can carry data or information permanently until it is overwritten or removed regardless if the storage space device has ability. The secondary storage area devices are usually refer as follows: hard disk drive, floppy drive drive or etc. Although principal storage is reached faster than extra storage, however the secondary safe-keeping has more features than the principal storage. An eHow contributor say there are four types of functions of the extra storage.
Data or information backup
External hard drive
Network attached storage
For travel and easy transport
Data or information back up: The primary of function of the secondary are being used for a very simple job that is backing up data or information. The data or information such as statement, music, training video and other components of value. Thus, backing up data is actually prevent when hard drive crashed but the data even are present.
External hard drive: other function of the secondary storage space is to serve as an exterior hard dive. That may be help to increase memory to store more data and information while internal hard drive gets full because that simplifies the process of changing more storage just need to with a USB slot then can be use the exterior hard drive such as pen-drive.
Network attached storage space: Using network attached safe-keeping can be easier to share any data files for each team when the department's extra storage device hook up to the network.
For travel and easy move: These years the supplementary storage devices have become more lightweight as the technology is enhancing a lot. Another common use of extra safe-keeping device is to transport data or information. Whatever you will need to bring documents to your friends or even though just want run an application to them, the extra storage device can do the secret.
So, this is the reason why the secondary storage device is more popular than the principal storage space device.
Now, we choose a job which is Airlines Company, and discuss why data storage area devices are essential to them.
Previously, we selected Airline Company to be our concentrate on in this subject. So, the next section we will target in data storage devices of Flight Company. Airline Company is a profession which is high investment, high risk and high income.
So, Air travel Company attaches great importance to any subject, they could be include technology, services, system, or even hardware. Among the hardware is data storage devices also attaches great importance in Flight Company. As the Airline Company is an international company, so they need to have to store the mass amount of data or information such as customer's information, data of aircraft come from each country, marketing research, each department's data and etc. Could anyone consider if the Air travel Company is not to support properly storage space devices? Then, the Air travel Company can't record anything from customers, uncertain the aircraft is come from which country, not yet determined the going on of market, department's operation. That assumption shows if the Airline Company never to support properly safe-keeping devices then will lead any data or information to be perplexed. So, the Air travel Company must be having data storage devices that are high quality, powerful and high stability. Then, the Flight Company is able to solve these problems.
For other example, due to the Airline Company's areas are rely upon each other, therefore the Airline Company may use storage area network (SAN) that is a network fully devoted to copy and storage of data or information between machines and storage area devices from each sectors. Storage space network not only support to transfer and storage data, it also can back up much bigger levels of data at a time. In addition, when broadband of data copy is important, such as with online business deals of the Air travel Company that involve a large number of details in a stored data source. A lot of users can gain access to data without delays at exactly the same time. Storage space network (SAN) can solve these problems as storage area network (SAN) is highly scalable that are being used by organizations that do business on the net and require high volume level transaction processing. Thus, storage space network (SAN) is essential for the Airline Company. An excellent and perfect of data storage space device not only maintain operation of the Airline Company that also can gain competitive edge. We will discuss how to help the Airline Company used data safe-keeping devices to get competitive advantages in the next section.
Now, we realize data storage area devices are important in the Air travel Company. The Air travel Company use data safe-keeping devices in multiple goal and gain the competitive advantages at the same time. Therefore, we will describe some of the data storage space devices they used in the Flight Company and help the Air travel Company to get competitive advantages in this section.
First of all, we will provide successful example in the real world. That is North american Airlines, the world's largest carrier. They also need to increase earnings by reducing fraudulent ticket processing. That mean is they have to discover a way to quickly and effectively query their data warehouse. John Hagen, he's mature system analyst and job manager in North american Airlines. He says:" Just what a technology can do for the company's customer is the ultimate important thing. Sybase IQ has plainly had a substantial, positive impact. It includes turned out to be a win-win for all of us and our customers. " To put it simply, the North american Airlines needs a data warehouse it could be detect deceptive ticket-processing and keep tabs on these tickets deal properly and ensure proper income is flowing in to the American Airlines. That mean the Sybase can do just fine. A result symbolizes the Sybase can helps American Airlines to save about $5 million in five years as fast random inquiries helped expose deceptive ticketing and saving about $250, 000 in development costs. The Sybase can also be significantly reduces the space required to store data when data is increase daily. So, the Sybase is undeniable that can gain competitive advantages for the American Airlines.
For another example, a CNET contributor say Hainan Airline used a data storage area which is easy, easy to manage, with high flexibility, high stability and scalability. That called as NetApp. The NetApp can help Hainan Airline to help ease the pressure on the data surge and helps to achieve the centralized storage space of data. The NetApp also helps Hainan Airline to achieve storage area loan consolidation and the provisioning of NetApp upgraded utilization of storage area capacity therefore the NetApp can reduce safe-keeping costs and gain competitive advantages at exactly the same time.
Finally, we realize data storage area devices are refer to primary storage and secondary safe-keeping. The primary storage space is a volatile medium that can only just used when the power has on. As the secondary storage space is a nonvolatile medium you can use even if the energy goes off. In addition, we know the importance of data storage space devices and storage space network (SAN) is important in Airline Company. We also find out about North american Airlines used the Sybase to trail solution sales properly and ensure proper earnings is flowing to their company. Another one is Hainan Airlines used the NetApp to accomplish storage loan consolidation and the provisioning help to improve capacity of storage space.
Both of them are being used data storage space devices to get competitive advantages. Thus, in this section we know about types of data storage area devices, the value of data storage devices or even using these data storage space devices to gain competitive advantages.
