...Mobile database A mobile database is either a stationary database that can be connected to by a mobile computing device ( eg smartphone and PDA) over a mobile network OR A database, which is actually stored by the mobile device this could be list of contacts, price information distance travelled or any other information Many applications require the ability to download information from an information repository and operate on this information even when out of range or disconnected. An EXAMPLE of this is your contacts and calendar on the phone. In this scenario a user would require access to update information from files in the home directories on a server or customer records from a database. This type of access and work load generated by such users is different from the traditional workloads seen in client-server system of today CONSIDERATION • Mobile users must be able to work without a network connection due to poor or non existent connections. A cache could be maintained to hold recently accessed data and transactions so that they are not lost due to connection failure. Users might not require access to truly live data, only recently modified data, and uploading of changing might be deferred until reconnected • Bandwidth must be conserved (a common requirement on wireless networks that charge per megabyte or data transferred) • Mobile computing devices tend to have slower CPU and limited battery life • Users with multiple device (eg. Smartphone and tablet) need...

...LEGO - EMBRACING CHANGE BY COMBINING BUSINESS INTELLIGENCE WITH A FLEXIBLE INFORMATION SYSTEM History of LEGO Company The LEGO Group was founded in 1932 by Ole Kirk Kristiansen. The company has passed from father to son and is now owned by Kjeld Kirk Kristiansen, a grandchild of the founder. It has come a long way over the past almost 80 years - from a small carpenter’s workshop to a modern, to a global enterprise that is now, in terms of sales, the world’s fourth-largest manufacturer of toys. The name 'LEGO' is an abbreviation of the two Danish words "leg godt", meaning "play well". The original Lego toys started with a wooden duck. But the first LEGO automatic binding brick is their most important product. The products have undergone extensive development over the years – but the foundation remains the traditional LEGO brick. The Lego Group began in the carpentry workshop of Ole Kirk Christiansen, in Billund, Denmark in 1916. In 1961, Lego wished to expand sales to North America, but did not have the logistical capabilities to do so. Lego made an arrangement allowing Samsonite to begin producing and selling Lego products in the United States and Canada. On 7 June 1968, the first Legoland Park was opened in Billund. This theme park featured elaborate models of miniature towns built entirely from Lego bricks. The three acre (12,000 m²) park attracted 625,000 visitors in its first year alone. During the next 20 years, the park grew to more than eight times...

...Case Questions 1. A decently overseen database may help the healing center accomplish its mission by the following points: * Cost of the each treatment in similar hospital is stored in the database to compare rate with other hospital. * Physicians can gather the relevant information quickly by providing the electronic medical record for each patient. * To find which programs and methods are best, create a historical record of the treatments. * Track the important measure to provide the data and information for example, normal length of patient wait, price for each day for a patient. 3. Hospital should carefully manage some of the cost and risk of using database because in a job market, there is short supply of skills such as database designer and database administrator. Without the specific faculty, it creates a risk to manage the database. The installation and administration expenses include updating software and installing of database and hardware. The translation cost includes the converting cost of older application into database environment. Instead of converting the hospital can choose new system. There is a need for the backup and recovery because the framework expenses are connected with those strategies. A hospital must predict the data administration cost and other activities cost related to data definition, ownership and maintenance. 6. Mountain View Hospital could use web based applications in a few ways. * Internet hospital personnel uses...

Software provide description to your computer’s hardware. Your PC or Mac would become useless if without it. There including three main types of software, that is application software, system software and programming software. , The most important type of software for computer users is application software, because it can used to achieve many of the tasks so that we can turn to our computers in the first place, such as Web browsing, word processing, and data crunching. Application software applies the power of system software. This is why when downloading software, you have to find a version that fits with your running operating system (OS). That software draws on the OS to create a spreadsheet, PowerPoint presentation or Word document in essence. The software that it worked like in your house pipes run behind the scenes to keep things invisible is programming software, or middleware. System software includes all components of the computer's operating system (OS), including configuration files, other key system components and device drivers. This software provides a basis for the system and tell the computer’s hardware what to do. Analysis There have been debates...

...Internet and mobile access components When designing a unified, single system intended for total company-wide access, it is important to allow for maximum access. If employees cannot access the system, data cannot be added, and the master databases will not reflect the latest data. On this same note, executives who cannot access the system will not be up to date on current numbers, which may affect current decisions and future plans. Riordan’s unified data system will be accessible through the internet via Virtual Private Network (VPN) channels. The system will not have a mobile application, though the internet portal will be accessible through smartphones and tablets. Riordan’s unified system will be hosted at the company headquarters, but employees will access the system through the internet. This is for several reasons. First, it provides a single point of access for all employees, whether they work at the company headquarters, at one of the Riordan’s outstations, or while they are at home or on travel. A single point of access means a single point of failure, which will help the IT department resolve access issues quickly. Additionally, an online access point keeps users from directly accessing the main system database, which could result in data loss or errors created by users poking around in the main system. To sign into the system at work, users will access a link on the company intranet. There is no need for additional login, because the users are already...

...Big Data [Name of Writer] [Name of Institution] Introduction The term Big Data is gaining more followers and popularity. However, despite this trend, not all organizations are clear about how to face the challenge to store, organize, display and analyze large volumes of data. The term Big Data is gaining more followers and popularity. However, despite this trend so evident, not all organizations are clear about how to face the challenge to store, organize, display and analyze large volumes of data. There are multiple techniques in terms of huge database storing approaches that can store petabytes, exabytes and may be zetabytes data. These options are Cassendara, Mongodb and HBase. We will discuss about them one by one and in a proper research method and will compare them in order to contrast their difference and efficiency. Research Background One problem in understanding the phenomenon is that the size of these data sets the volume greatly exceeds the Data warehouse. A plane collects 10 terabytes of information from sensors every 30 minutes flight, while the Stock Exchange of New York collects structured information 1 TB per day. In the context of Big Data, volumes are reaching peta bytes, exa bytes and then soon to zeta bytes. For instance, Apple has just announced that 7 trillion send daily notifications to iOS devices. The explosion of information in social networks, blogs, and emails is characterized the presence of data key...
