Massive data a problem… not really {2}

by Robert Q
This article titled “Storing Massive Data: Distributed Data and the no SQL Movement”, talks about the general programs that are available to handle the problem of massive data. The author points out that “big data” is just huge amounts of information that are collected from all parts of the internet. The author explains some of the available software that are there to improve the storage of these data. Some of the software that the author mentions are Hadoop, Cloudera and Hortonworks, there are many other software that the author mentions. The author noticed that businesses are trying to find better and better software to handle their demand of information. Companies are starting to as some vendors such as Amazon and Oracle to develop better software that can handle real-time analysis database. As information continues to grow the future for this industry would appear to continue in its positive growth. read more...

Google Drive Privacy {2}

by Ricardo C
This article talks about the new Google cloud service called Google Drive. Microsoft’s cloud service and DropBox have been the largest cloud storage services for many years and many people were expecting Google to come up with a cloud service. A lot of internet users have services from Google such as email, web based applications such as Google docs, Blogger, etc, and a cloud service would consolidate all of the essential internet services in one provider. However, people need to be aware of the terms and conditions of each provider. For instance, Microsoft and DropBox do not claim ownership of the files that one uploads to their cloud service and maintains them private, on the other hand, Google Drive explicitly says that “Your Content in our Services: When you upload or otherwise submit content to our Services, you give Google (and those we work with) a worldwide licence to use, host, store, reproduce, modify, create derivative works (such as those resulting from translations, adaptations or other changes that we make so that your content works better with our Services), communicate, publish, publicly perform, publicly display and distribute such content.
The rights that you grant in this licence are for the limited purpose of operating, promoting and improving our Services, and to develop new ones. This licence continues even if you stop using our Services (for example, for a business listing that you have added to Google Maps).” read more...

Devices To Store Data {7}

by Jamal A
Over the past decade, the world has changed a lot, but so does the technology. We have seen technology leap beyond our wildest dreams.   However, database is the main part of the technology. The article I read basically talks about the potential storage devices and technologies that can be used for database storage. Data is the greatest asset for all businesses whether it is big or small. Most companies are taking data storage very seriously.  It is really important to back up data frequently specially for sales companies. According to the article, “in a simple sales transaction, a primary use of data could be inventory control, where a report shows how much of a product has been sold and how much remains in storage”. Majority of companies use hard disk to store important data. “Hard disks are random-access storage mechanisms that relegate data to spinning platters coated with extremely sensitive magnetic media”. Advancement in technology has made hard disks the cheapest storage device for large volumes of data. However, Hard disks are electromechanical devices and their working life is limited. It does not matter if the hard disk is new or old, it can easily get damaged and cause issues when rendering the data from the drive. In order to solve that issue, disks are frequently organized into groups of disks usually called Redundant Arrays of Inexpensive Disks (RAID).  According to the article, the goal of RAID is to confirm data availability. There are different ways to configure RAID but the most common are; “RAID-0- In which “disk striping is used to improve storage performance, but there is no redundancy”. “In RAID-1 — disk mirroring offers disk-to-disk redundancy, but capacity is reduced and performance is only marginally enhanced”. In RAID-5 — parity information is spread throughout the disk group, improving read performance and allowing data for a failed drive to be reconstructed once the failed drive is replaced. In RAID-6 — multiple parity schemes are spread throughout the disk group, allowing data for up to two simultaneously failed drives to be reconstructed once the failed drive are replaced”. There are total seven layers of storage, the very first layer known as zero (0) layer and it goes up to six (6) layers, which is the last layer of storage. Majority of the companies uses the first lays because it is easier to sat up and also very reliable. read more...

Dropbox for Teams: Cloud Storage for Business {2}

by Daniel L
Many of us have either heard of or used Dropbox to move our files between computers and other devices.  Dropbox has grown to become a recognized internet based file hosting provider and go-to service for backing up files primarily for individual consumers.  Dropbox wants to change that by reaching out to business users as well.  There are a lot of businesses out there who have employees that like to share files and documents with their coworkers and clients, and have used the Dropbox services in the past.  To help provide more solutions for businesses, Dropbox has developed a business-oriented version of their service called Dropbox for Teams.  Typically, individuals who start a Dropbox account, have access to 2GB of storage at no cost, businesses  with a Dropbox for Teams service on the other hand, start with 1TB of storage that five users can share, with a price tag of $795 dollars a year.  It is important to note that if the users that are sharing the 1TB of space end up needing more storage, they can add as much as they need, upon Dropbox’s approval and quota.  At first, the price for the 5 user Dropbox for Teams service may sound quite expensive, but if you were to compare the individual plans with 100GB of storage at $239.88 a year, with the $159 per person price-tag of a Dropbox for Teams service with potentially unlimited storage, the Team option is the clear cut winner for business oriented cloud storage needs. read more...

Run out of Hard Drive Space? Get the Salt {2}

by Daniel L
Music libraries are growing, high definition content is everywhere, image quality is getting better and better, but what happens when there is not enough storage space to store these bits and pieces of data.  That is where researchers in Singapore took a break from increasing their sodium consumption levels, and devised a way of increasing hard drive platter data density by using everyday table salt.  The large capacity hard drives that are available today are capable of storing 4TBs (terabyte: 10^12); however, with this technological breakthrough, a single drive can hold 5.3 times the amount of data, amounting to more than 21TBs.  The process involves adding a sodium chloride solution to nano-sized circuitry in order to produce microscopic structures capable of carrying information in the form of bits.  Joel Yang, a scientist from MIT was the first to develop this method of closely packing these data structures together, which is referred to as nano-patterning.  Traditional storage technology uses tiny portions of packages composed of bits, around 7 to 8 nanometers in size, deposited on a hard drive platter in a cluster group.  Yang describes that the researchers were able to take the single bit of data stored in those groups of packaged clusters, and downsize it to a single structure. read more...
