Praticamos os conceitos apresentados neste capítulo no Apêndiceonde ilustramos o documento de arquitetura do SASF.

Dificuldades da documentação

Apesar dos benefícios proporcionados pela documentação daarquitetura, documentá-la não é fácil. A dificuldade de documentar a arquiteturareside, principalmente, em três características que descrevemos a seguir:

  • o documento reflete o tamanho da solução;
  • o documento reflete a complexidade do design da solução;
  • é custoso manter o documento consistente com o designatual ao longo do ciclo de vida do software.

O tamanho do documento

Projetos de grandes sistemas de software são os quemais se beneficiam com o design e com a documentação da arquitetura.Isto ocorre porque o design e a documentação proporcionam orientaçãona implementação dos requisitos de qualidade, ajuda no controleintelectual sobre a complexidade da solução e servem de ferramentaque promove a integridade conceitual entre os stakeholders.

No entanto, um grande sistema de software implicanuma grande solução de design, que deve conter muitas decisõesarquiteturais e que devem ser apresentadas a muitos stakeholders, que demandamvisões diferentes. A consequência disso é que a arquitetura de umgrande sistema deverá ser apresentada em um documento extenso.

Documentos muito extensos podem ser fonte de algunsproblemas durante o processo de desenvolvimento. Entre estes problemas,podemos citar que eles levam muito tempo para serem construídos eque, em geral, geram uma certa resistência para serem lidos ouatualizados durante o desenvolvimento. Se o documento não é lido ou nãoé atualizado durante o desenvolvimento (e isso pode ocorrer porque a arquiteturapode evoluir ao longo do tempo, seja a evolução planejada ou não),ele corre o risco de ficar inconsistente com a realidade do software, tornando-seuma fonte de informação inútil e, portanto, deixando de proporcionaras vantagens de se projetar e documentar a arquitetura.

A complexidade do documento

Tanto o tamanho do documento quanto a complexidadedo design influenciam na complexidade do documento da arquitetura. Umdocumento muito complexo, que usa muitas visões e diferentes linguagenspara descrever diferentes aspectos do software, é difícil de se construire de se manter consistente em caso de mudanças durante a evoluçãoda arquitetura.

Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world
