The hierarchical naming system for computers, known as the Domain Name System (DNS), in any source linked to the Internet or private network. This system connects diverse information with domain names assigned to each of the participants. More importantly, it communicates the domain names that humans understand into numerical (binary) identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide. An analogy used often to explain the Domain Name System is that it is like a phone book for the Internet. It translates language a human can understand to computer hostnames into IP addresses. For instance, changes to DNS known also as a distributed database that offers mapping between IP addresses and Host names. Using the Domain Name System it is likely to assign domain names to sets of Internet users in an important way, free of each user's actual physical location. Since this is possible, World Wide Web (WWW) hyperlinks and Internet contact information will stay dependable and unbroken even if the existing Internet routing arrangements become altered or change, or the participant uses a mobile device. Internet domain names are easier to remember than IP addresses such as (IPv4) or 2001:db8::1f70:6e8 (IPv6). Individuals take use this advantage when they talk about meaningful URLs and e-mail addresses without needing to understand how the computer will actually locate them. The Domain Name System allocates the accountability of assigning domain names and mapping those names to IP addresses by designating authoritative name servers for each domain. Authoritative name servers are set to be responsible for their specific domains, and in turn can assign other authoritative name servers for their sub-domains. This mechanism has made the DNS distributed and fault tolerant and has helped avoid the need for a single central register to be continually
Company Alpha already has an existing DNS namespace. Different locations or organizations can be named with different subdomains such as or to ease administration. Make Active directory child domain immediately subordinate to their parent domain in the DNS name space. You can choose to create subdomains for organizations with in your company or location for example These are a few things this company needs.
Company Alpha as all companies in my opinion should use a redundant DNS infrastructure. This will help with back up of the information in the system. With this being the age of information the ability to keep it safe and available is very important.

Integrating Domain Specific Needs

...Integrating Domain Specific Needs The creation of domain-specific modeling is a widely accepted tool to prepare for integration of domain-specific needs within an organization. Modeling is an accepted tool in software development and considered essential in the successful development and implementation of technology projects. These models use domain-specific language extensions to help expose attributes of the domain used by an organization. Domain-specific models offer input for the creation and mapping of the integration of computer requirements within the system. Decisions occur and are driven by the domain-specific modeling that reveals the specific needs of requirements (Center for Domain Specific Computing, 2009). Many computer languages are domain-specific and not written for general purpose. A domain-specific language (DSL) offers application-oriented and specialized purpose tailored to the needs of the domain and the applications required. There is no approach widely accepted as the best tool for developing domain-specific languages as each domain has its specific needs based on the organization. A DSL offers tailored solutions to domain specific problems. Often DSL’s provide increased productivity, reduce programming expertise requirements, and reduce maintenance costs. Though DSL development can be costly the benefits can often outweigh the risks and reduce costs. Language development applications and toolkits offer assistance in creating DSLs (Mernik, Heering,......

...will no longer exist. Implementation Plan A well-designed Active Directory structure is critical to the successful deployment of a essential system, implementing an Active Directory environment, the benefits of doing so far outweigh the negatives. To get started there are three models to choose from when laying out an Active Directory structure: 1. Single forest, single domain 2. Single forest, multiple domain 3. Multiple forest, multiple domain Choosing the Right Model is an important step, some features to consider is simplicity, high security, high reliability and low cost of operation all of these were the primary objectives considered when choosing the right Active Directory structure. The structure that would meet these objectives is a "single domain" model. In this model, all information is organized within a single Windows Domain. Within that Domain, logical containers - called "Organizational Units" - will be created for each Department within the corporation. Each department will have complete control over its own Organizational Unit - Administrators within each department will have the ability to manage their own users, groups, servers and services as necessary.

...AI semantic networks, ontologies are becoming an essential component of many modern systems. An ontology is a set of specifications, relationships and constraints that describe a certain domain. These specifications capture the concepts pertaining to the domain. Research in this domain is now witnessing intensive efforts due to the growth and success of distributed computing systems in real world applications such as eCommerce, eHealth, eLearning and other eServices. Though at the core of modern distributed technologies, such as multi-agent systems, the ontology issue has sometimes been considered secondary and related issues are underestimated. In this paper, we attempt to address the ontology issue in modern distributed services, and the various problems to be investigated, with special emphasis on eCommerce systems. Our paper illustrates how the semantic-web initiative integrates with ontology. It critically appraises existing solutions, and offers ideas for tackling major ontological issues in eServices. 1. Introduction Distributed systems is the future computing model. This fact is proved by the success of the client-server model and the recent extensions to that model. Maturity of cheap PC, networking and communication technologies contributed to the wide spread adoption of this model. The advent of Internet and the services developed for it gave solid successful examples of distributed systems, even when the underlying network is a hybrid network like the internet.......

...What are a domain, forest, and namespace? Domain – The logical directory components created to manage an organization; acts as a container for organizational units. Forest – The top-level container within the active directory environment; acts as a collection of domain controllers within an organization Namespace – Defines the scope of the AD and then breaks off into a forest of names. For example, a namespace could be with branches going to and Why are contiguous namespaces important when designing a domain structure or model? A contiguous namespace is important when designing a domain structure or model because it helps to define the exact structure of how everything is laid out.

This article the importance of the Revised Bloom’s Taxonomy to nursing education and how to design a lesson plan focusing on transferring knowledge (Osisek & Su, 2011). In 1956, a committee under the direction of Dr. Benjamin Bloom, produced the initial Bloom’s Taxonomy to stimulate advanced methods of rational in education. As opposed to remembering facts, it focuses on analyzing and evaluating. There are six key reasoning categories that range from modest to complex. The types are knowledge, comprehension, application, analysis, synthesis, and evaluation. The cognitive domain knowledge, involves the capacity to remember details and explicit information that serve in the development of intellectual capabilities and skills. Comprehension entails the ability to understand the meaning of theories. Application requires the student to apply the skill learned into circumstances at work. Analysis requires the ability to separate information into facts and implications so it may be understood. Synthesis involves putting thoughts and perceptions together to formulate a new meaning. Evaluation requires the ability to judge the effectiveness of an idea or product (Osisek & Su, 2011). In the mid-nineties, a former...

Uml Term Papaer on Domain Analysis

...LOVELY PROFESSIONAL UNIVERSITY TERM PAPER ON Extending UML to Support Domain Analysis SUBMITTED TO:- SUBMITTED BY:- Mr. SANDEEP SINGH AKANSHU KUMAR Reg No:-11112286 ROLL No:- A21 SECTION:- K1107 Abstract:- The process of modelling and developing commonality and variability for system families should be supported by suitable methods and notations. The object-oriented methods and their notations, which are used at present, focus on the development of a single system at a time. In this paper we analyse feature models as a representation of the common parts and variants contained in a system family, and propose using a feature diagram as a basic representation of commonality, variability and dependencies. We examine various approaches to customizing the standard modelling language UML to model system families and propose how to extend the UML for the purposes of modelling variants in object-oriented analysis and design techniques. We recommend the use of UML standard lightweight extensibility mechanisms (stereotypes combined with tagged values) without changing the UML metamodel. This enables us to join the advantages of feature models with UML and provides the traceability of a concept throughout......

...responsibilities and methods. Before I go into detail about the responsibilities and methods, it’s important to first understand that the focus of object design is to: * Identify classes and objects. * Decide what methods belong. * Where and how these objects should interact. See, responsibilities are assigned to classes during object design. There are two types of responsibilities, the “doing” and the “knowing.” The “doing” is known for doing something itself; it initiates the action in other objects and controls/coordinates the activities in other objects. The “knowing” is more about the related objects, private encapsulated data and things it can derive/calculate. Responsibilities related to “knowing” often are inferable from the Domain Model because of the attributes and associations it illustrates. That being said, a responsibility is not the same thing as a method, even though methods are applied to satisfy responsibilities. Methods are branded to either act alone or join forces with other methods and objects. Ensuing in the slides, we find refactoring. Refactoring is a well-ordered technique for restructuring an existing body of code,...

... the affective domain of learning is used to develop interpersonal competence, self-awareness, and self-reflection. The teaching technique used is an experiential exercise that asks students to create group mandalas using art materials on circular pieces of butcher-block paper. The mandala concept is derived from the Buddhist tradition and means “circle” or “center” in Sanskrit. Carl Jung introduced this technique to the United States and incorporated it into his therapy. As a creative, active learning strategy, the mandalas helped the faculty meet the clinical objectives for the course and the learning needs of a new generation of students. They also helped students learn about Eastern philosophy, group process, self-awareness, and Jungian therapy.
