Data architecture In information technology, data architecture is composed of models, policies, rules or standards that govern which data is collected, and how it is stored, arranged, integrated, and put to use in data systems and in organizations.[1] Data is usually one of several architecture domains that form the pillars of an enterprise architecture or solution architecture.[2] Overview[edit] A data architecture should[neutrality is disputed] set data standards for all its data systems as a vision or a model of the eventual interactions between those data systems. Essential to realizing the target state, Data Architecture describes how data is processed, stored, and utilized in an information system. The Data Architect is typically responsible for defining the target state, aligning during development and then following up to ensure enhancements are done in the spirit of the original blueprint.

Enterprise architecture planning Levels of Enterprise Architecture Planning.[1] Enterprise Architecture Planning (EAP) in Enterprise Architecture is the planning process of defining architectures for the use of information in support of the business and the plan for implementing those architectures.[2] Overview[edit] One of the earlier professional practitioners in the field of system architecture Steven H. This hierarchy of activity is represented in the figure above, in which the layers are implemented in order, from top to bottom. EAP topics[edit] Zachman framework[edit] EAP defines the blueprint for subsequent design and implementation and it places the planning/defining stages into a framework. EAP is planning that focuses on the development of matrixes for comparing and analyzing data, applications, and technology. EAP components[edit] Enterprise Architecture Planning model consists of four levels: EAP methodology[edit] Applications[edit] See also[edit] References[edit] Further reading[edit] Steven Spewak with Steven C.
Modelo em cascata Origem: Wikipédia, a enciclopédia livre. O modelo em cascata é um modelo de desenvolvimento de software seqüencial no qual o desenvolvimento é visto como um fluir constante para frente (como uma cascata) através das fases de análise de requisitos, projeto, implementação, testes (validação), integração, e manutenção de software. A origem do termo cascata é frequentemente citado como sendo um artigo publicado em 1970 por W. W. Royce; ironicamente, Royce defendia um abordagem iterativa para o desenvolvimento de software e nem mesmo usou o termo cascata. Royce originalmente descreve o que é hoje conhecido como o modelo em cascata como um exemplo de um método que ele argumentava ser um risco e um convite para falhas. História do modelo em cascata[editar | editar código-fonte] Em 1970 Royce propôs o que é agora popularmente designado no modelo em cascata como um conceito inicial, um modelo no qual ele argumentava ser defeituoso.

Processo de desenvolvimento de software Origem: Wikipédia, a enciclopédia livre. Um processo de desenvolvimento de software é um conjunto de atividades, parcialmente ordenadas, com a finalidade de obter um produto de software. É estudado dentro da área de Engenharia de Software, sendo considerado um dos principais mecanismos para se obter software de qualidade e cumprir corretamente os contratos de desenvolvimento, sendo uma das respostas técnicas adequadas para resolver a Crise do software.

» Enterprise Agility – Patterns - People10 I had written a blog earlier on ‘how agile are you : an assessment”? It created some debates on various types of agility across the enterprise.. ‘Agile for me’ is not the same as ‘agile for you’. Thanks to Rakesh, I have this nice illustration with which I can share with you the evolution of agile across different types of IT application scenarios. Enterprise agile patterns ( Idea & Illustration : Rakesh Dahiya) As you can see here, the degree of agility (ability to deliver early value to business ) goes up as you move up the chain. I will explain the legends here a bit so that you can easily read the diagram. At the bottom of the stack, you can see the waterfall, that does not need any explanation Just note when you are realizing the earliest business value in this model (orange dot)! Above the waterfall, you see the pattern for Enterprise packaged software like ERP systems and enterprise data Warehouses. Next we move up to the classic requirements of ‘Custom Application development’.
Portfolio management tools draw roadmap for business transformation The enterprise architect’s world today is in constant flux. The corporate landscape is shifting. As it now exists, it is very much built on mergers and acquisitions. Each merger brings with it software legacy. Most acquisitions bring along a hope to transform the original businesses. portfolio management tools are being used to move newly complex organizations forward. However, portfolio management is not a slam dunk. “We are still waiting for the emergence of a more unified set of tools and approaches,” he says. Portfolio management or application portfolio management (APM) did not grow directly from project portfolio management, but it was highly influenced by project management methods. “Speaking as someone who has implemented IT service management tools, in my view the enterprise architects tend to have their boxes and lines and want to draw capability maps and document system interactions,” he says.

Is your software app portfolio out of control? While they may be the last to admit to it, many organizations have an app problem. They may not think so, but it's true. The fact is, as many large companies grow, merge and acquire other organizations, they end up accumulating an excessive number of applications. Like a hoarder who won't throw anything away, large corporations often find themselves in possession of more software than they need and paying licensing costs for software they don't use. And the problem isn't just financial; compatibility issues often emerge on the desktop, as legacy software clutters up the app portfolio. Are you thinking that your organization might be suffering from software overload? How many apps does your enterprise have in its portfolio? If your organization is getting ready to squabble over the budget for yet another "wish list" of applications, it's time to take a step back and rethink the approach. Timely advice from Gartner How do you decide what must go and what should stay?

Introduction TOGAF is a framework - a detailed method and a set of supporting tools - for developing an enterprise architecture. It may be used freely by any organization wishing to develop an enterprise architecture for use within that organization (see 4.5.1 Conditions of Use). TOGAF is developed and maintained by members of The Open Group, working within the Architecture Forum (refer to www.opengroup.org/architecture). Starting from this sound foundation, the members of The Open Group Architecture Forum have developed successive versions of TOGAF and published each one on The Open Group public web site. If you are new to the field of enterprise architecture and/or TOGAF, you are recommended to read the Executive Overview (refer to 1.2 Executive Overview), where you will find answers to questions such as: What is an enterprise? 1.1 Structure of the TOGAF Document Figure 1-1: Structure of the TOGAF Document There are seven parts to the TOGAF document: 1.2 Executive Overview What is an enterprise?
An Enterprise Architecture framework definition - Enterprise Architecture Matters Continuing one of my own recent posts: "the question is for us if we do need an EA framework... We do because the framework embodies, in a structured manner, the long experience of the many of us and our companies... The framework saves a lot of effort and costs since it leaves the architect focus on own Enterprise issues. But can we talk about Enterprise Architecture frameworks without defining them? A popular opinion is that we don't even need an EA framework. I begin with the critique of existing "frameworks" to explain why we need to move on. Zachman's is called a framework but some say it is an ontology; in truth it is mainly a method of analytic thinking used more for scoping and selling EA than anything else.TOGAF is a process (ADM), buried under plenty of additional and often disjoint information, hard to read and use.FEA is a US federal program, a process (FSAM) and a set of a few common EA views that should bind together the EAs developments in each government agency. 2. 3.
