  • Characteristics Of Creating An Oracle Database

    will recover failures before even users detected that a problem has occurred. Going along with the error detection is recoverability and the fact that oracle software has a Fast Application Notification and Fast Connection Failover and will start a recovery as soon as the instance detects and failure in the cluster and will start it automatically as well. Lastly is the continuous operations and that the cluster servers will continue to remain open and work during any delay in service, this also means that the maintenance of these servers can be done in a systematic manner keeping the downtime to almost nothing. When talking about those major attributes for Real Application Clusters and how effective they can be then we can talk about the scalability and the cost effective workload that a cluster of servers can provide. Being able to scale the amount with how big your business is and what exactly your business needs it for as in more speed and better performance means that the scaling of this equipment is the best part about oracle databases. When it comes to Input/output (I/O) performance we have to look at the operations that are on hand. There are different means to change the performance of the reading of files on a database. Now if you were looking to store information on a database using hard disk drives or the more expensive but more powerful solid state drives that are about four times faster while using half the power draw solid state drives are by far the better…

  • Mapreduce Rendezvous Hasing Based Virtual Hierarchies: The Cassandra Nosql Case Study

    The gradual transformation in data quantity has resulted in emergence of the Big data and immense datasets that need to be stored. Traditional relational databases are facing many difficulties meeting the requirements of the volume and heterogeneity structure of big data. NoSQL databases are designed with a novel data management system that can handle and process huge volumes of data. NOSQL systems provide horizontal scalability by supporting horizontal data partitioning across heterogeneous…

  • Teradata Case Study

    Teradata is basically a database that is designed to handle queries. It is a relational database management system for the world's largest commercial databases. Other RDBMS takes enormous time to process and execute the data. But Teradata RDBMS handles massive amount of data with ease. The main attraction of Teradata is its scalability, parallel processing and high performance. It generates an optimal plan for the query within few seconds. Teradata can save upto Teradata bytes in size. The…

  • Analysis Of Food As A Medicine: A Symptom Of Poverty

    project aims to address hunger, and reduce waste, by distributing foods which would otherwise be cast-off to landfills. The ‘Food Recovery’ project with acquisition unused food for redistribution to strengthen the food security of households living in poverty. The program implements a system for fresh food delivery in Alameda County which addresses access issues which can limit households living in poverty from gaining access to nutritious foods. • Increase CalFresh Enrolment: This project aims…

  • Why Does Visser View Walmart As An Example As A Company Worthy Of Emulation

    It means seeing a call for help and wanting to do your part. “Responsibility is the counterbalance to rights. If we enjoy the right to freedom, it is because we accept our responsibility not to harm or harass others” (Visser, 2011. Pg.4). It is about doing to others what you want done to them. If we want people to be more sustainable and focused on the environmental needs of our world, we ourselves need to do the same. If we work together and each make a small change in the way we carry out our…

  • Amazon Company Reliability

    and solutions of building a highly available, scalable and reliable distributed system by the name Dynamo are addressed by the Author in the article. Reliability will be achieved by using the replication. Sloppy quorum and anti-entropy with Merkle trees will be used for management impermanent, permanent failures. Incremental scalability will be achieved by use of constant hashing to divide the keys. The article addresses the problem that is based on building a production level highly available…

  • Challenges Of Cloud Computing

    small companies and startups run only with op-ex i.e. operating costs in business terms instead of cap-ex i.e. capital expenditure which would mean access to analytics which previously was only a part of large companies. Cloud computing makes the cost of 1 computer being used for 1000 hours more or less equal to 1000 computers operating for one hour. This means a change in strategy for analysis & design of systems, as cloud computing changes the scope of scalability & reliability with access to…

  • The Moving Particles MPS) Method

    of the currently available computational resources, such as computer cluster, remains as a challenge. One of the critical points due to the large amount of particles is the searching of the neighbors of each particle. On the other hand, to ensure the incompressibility of the flow, a semi-implicit algorithm that requires the solution of Poisson Equation of pressure is adopted, leading to the numerical computation of a very large linear system in every time step. In addition to this, unlike the…

    direct impact on the whole supply chain and may result in greater cost and reduced efficiency. As a big fish in the market, they need to have a system which can pop up the cost for every decision option in an instantaneous manner. Transparent System is specifically important while all the products become commoditized. In 19th centuries pricing, brand appreciation, features will be enough to set any business unique and to competent in the market. But in the current scenario, supply chain plays…

  • Advantages And Disadvantages Of Storage Systems For Big Data

    Storage Systems for Big Data Internet age comes with the vast amount of data that requires efficient storage and processing capabilities. To alleviate this issue, we discuss data storage systems which are tailored to store and process big data effectively. While general-purpose RDBMSs are still viable option in handling and analyzing structural data, they suffer from a variety of problems including performance and scalability issues when it comes to big data. To increase the performance of DBMS…
