However, they tend to use one well none map and reduce pattern to solve these problems. There are many other class of problems that cannot fit into this closed box which may be handed using other set of programming model. This is where Apache Spark comes in to help solve these†¦show more content†¦Spark s RDDs function as a working set for distributed programs that offers a (deliberately) restricted form of distributed shared memory. [3] The availability of RDDs facilitates the implementation of both iterative algorithms that visit their dataset multiple times in a loop, and exploratory data analysis, which is the querying of data repeatedly. The latency of applications builds with spark compared to Hadoop, a MapReduce platform may be reduced by several orders of magnitude. [3] Another key aspect of apache spark is that it makes writing code easy and quickly. This is as a result of over 80 high level operators included in with spark library. This is evidence as spark comes with a REPL an interactive shell. The REPL can be used t0 test the outcome of each line of code without coding the entire job. As a result, ad-hoc data analysis is possible and code is made much shorter. Apache Spark is well complemented with set of high-level libraries that can be easily used in the same application. These include Spark SQL, Spark Streaming, MLlib and GraphX which we will explain in details in this paper. 2 Spark Core Spark core is at the base of the apache spark foundation. It provides distributed task dispatching, scheduling, and basic I/O capabilities which is exposed through a common API (JAVA, Scala, Python and R) centered on the RDD concept.

Government Initiatives For Health And Oral Care - 1242 Words

1) Government initiatives to improve health and oral care Although oral health has improved significantly in last decades there is still room for improvement. Organisations such as National Institute for Health and Care Excellence (NICE) or The Faculty of Dental Surgery at the Royal College of Surgeons try to urge government focused on the issues such as increasing rates of oral cancer, impact of sugar on oral health, promote water fluoridation schemes or commit to further research on the link between oral health and general health. Government levy extra tax on the soft drinks is lately discuss, hot topic. But why is so important to keep sugar intake low? 2) What is the dental caries? Dental caries is disease of the tooth tissue caused by specific types of bacteria such as Streptococcus mutans. Weak acids are produced by the bacteria as they digest food particles found in the plaque. Acids gradually destroys the tooth s enamel and dentine with disease progressing in the pulp and potentially causing pulp death and loss of tooth. 3) Why is healthy diet important? Healthy diet is important not only because its reducing possibility of obesity, high blood pressure, heart disease or type 2 diabetes in later life, but also helping keep teeth healthy. After each food or sugary drink teeth are under acid attack for up to one hour. This is because the bacteria found in plaque, feast on the sugar, and produce harmful acids as a result. So it is important to have sugary foods orShow MoreRelatedBenefits Of Indian Health Services1001 Words   |  5 Pagesthink when you hear health care providers and the services they provide?

Information Technology for Florida Aspire Case - myassignmenthelp

Question: Discuss about theInformation Technology for Florida Aspire Case. Answer: Installation and data conversion Florida Aspire Case Kind of production conversion strategy In the Florida Aspire Project, deployment and cutover strategy is used for replacement of their financial management system, cash management system and other financial systems. The cutover of production is transferring of Aspire project solutions from the project team to the state of activities (Laudon and Laudon 2016). The end of production cutover process is initiation of application support per go live and then ongoing support. Choice of selection It is a good choice for the project as this strategy has covered the cutover categories such as people, data, process of cutover as well as technology. The cutover plan provides the project tasks with respective timing along with sequencing of necessary go live. ICT policies and information security Privacy risks of turnitin and blackboards The privacy risks are that any third party person can get password and username of the students, staffs and curtin those have accounts. Using it, they can access to the submitted papers along with personal information into the database. When the submitted paper is in hand of any unauthorized user, then they can use it for negative intention or hamper the career of the student. If the same paper is uploaded into another students portal, then it will be a life risk of them. Encryption techniques should be used by the users to keep all the sensitive data secured (Safa et al. 2013). The password of the students blackboard should be shared with anyone.
