exadata architecture

Overview:If the design is flawed at the architectural level, the solution is either farfetched or incomprehensible. It is difficult for a solution to apply DDD if it is built with a solution that relies on the inability to match the schema diagram and introduces too many dependencies. Architecture is a high-level design, if the design and understanding is wrong, will inevitably bring a variety of problems in the implementation. The

I have set up a dial-up access platform in CERNET, developed it on the front-end platform of the load search engine in yahoo3721, and upgraded the architecture of large-scale community sows, at the same time, I have worked with and developed many large and medium-sized website modules. Therefore, I have accumulated some experience in large websites to cope with high-load and concurrent solutions. I can discuss this with you. A small website, such as

Transferred from: http://kb.cnblogs.com/page/539838/In the previous article, we discussed what a schema is. In fact, these basic concepts are very important for architecture, and most people think they are aware of the concepts they are accustomed to every day, but in fact they are subconscious and not active. For example, "What is a table?" "When I do training, I often take this example to ask you, answer all sorts of strange things." This actually l

1, three-tier architecture The three-tier architecture of the three-tier architecture (3-tier application) is to divide the entire business application into the presentation layer (UI), the Business Logic layer (BLL), the data Access Layer (DAL). The purpose of distinguishing hierarchy is to think of "high cohesion, low coupling". 1, the performance layer (UI): P

in the Agile development , we did find a framework that would enable domain experts, architects, to work together to design an adaptable ROA architecture. But I think we should think of it from another angle. ...even domain experts and architects can work together in a team, but after all, domain experts and architects are people, not gods. So, in the end, how much of the future needs change can be predicted from the current version ? This is really
