disciplines, computer software design is still in its infancy and is constantly changing, such as newer methods, better algorithm analysis, and significant evolution of understanding. The methodology of software design has only appeared for more than 30 years. It still lacks depth, adaptability, and quantitative nature. It is usually more associated with classical engineering design disciplines. Even so, today's software technology already exists, de
Programmer A has met programmer B. "Scrum is terrible," said programmer. "Why? I heard that SCRUM is good. Our company is also preparing to implement scrum ." Programmer B answers. "Never, you will regret it ." "Are you implementing real scrum ?" "Of course, we have three roles, four meetings, and three products in scrum ."

Iii. New journey of Project Management
Preparing for the PMP exam and learning the PMBOK guide is just a process of consolidating basic project management knowledge. After you pass the test, you may not be able to immediately improve your work. Just as after reading a book about many ingredients, you don't have to make delicious food right away. After a large number of ingredients, to make food, you also need to "processing technology ". Such a processing technique is what
you want them to perform, instead of asking questions about the object status, and then you decide what actions you want to perform. This principle helps to match responsibilities and avoid close coupling between classes.
4. You don't need it (yagni)The yagni principle means that you only need to include the functions required by the application, rather than trying to add any other functions that you think may be needed. Test-driven development (TDD) is a design
structure rationality of the system.The structured design method is based on top-down, gradual refinement, modular as a base point, with modularity, abstraction, decomposition-by-layer refinement, information concealment localization and keeping the module independent of the design software data architecture and module architecture methodology.Structured methods are divided into software lifecycles, structured analysis (SA), structured Design (SD), and structured implementation (SP). It should
concise and easier to maintain. This example is very simple, in fact, the project may have more complex situations, in short, should be as dry as possible, to extract the duplication of things.
3. Writing order
This writing order refers to the writing order of each style, and the following is the recommended CSS writing order
(1) Position attributes (position, top, right, z-index, display, float, etc.)
(2) Size (width, height, padding, margin)
(3) Text series (font, Line-height, letter-spacing,

Three elements: methods, tools, processes 2. The traditional method features: the traditional methodology divides the whole process of software life cycle into several stages, then sequentially

Why discard: DBCC Repair requires the database to be in emergency mode, and it will try to use the existing log to restore the database to consistency (consistent recover ). If there is a problem with the log, it will recreate the log (I think this is what repair allow data loss means ). for a database larger than 100 GB, rebuild log may take several hours. Considering the recovery time object (RTO) and SLA (service level agreement ), database downtime is not allowed for a long time (refl

implementations to tailored ones. But for the CRM project, the metaphor may still be a rush, and it could give us a dangerous technical illusion. No matter how smooth the implementation, the performer's skill is not a substitute for the enterprise's own learning and adaptation process. And this process is doomed to slow, including a lot of repeated, as the enterprise understanding of CRM gradually in-depth, many business needs will gradually sprout or a dramatic change. All these, all decided t
October 2005, Bob Iger has become the company's new CEO, and he has turned the company into a "drink of cold Water" profit machine: In three years, Disney's revenue from the end of 2005 from 31.3 billion U.S. dollars to 37.8 billion, profits from 2.5 billion to 4.4 billion. This growth in the media industry as a whole is inferior to Google's one. The deep change is that Bob Iger the profits by nearly doubling, without doubling the company's line of business. In fact, he has been shortening the

Bottom-up approach (bottom-up approach): For database design, a design methodology that starts with identifying each design build and then aggregates the components into a large unit. In database design, you can start the underlying design from the presentation property and then combine those attributes together to form a table representing entities and relationships.

A qualified software engineer, is a true understanding of the nature of software products and software product development of the idea of the essence of people (personal views, welcome to explore).

Why to give up: DBCC Repair requires the database to be in emergency mode, and it will attempt to restore the database to consistency (consistent recover) using the existing log. If the log has a problem, it rebuilds the log (which is personally thought to be the meaning of repair allow data loss). For a database of more than GB, rebuild log can take hours, given the recovery time object ( RTO) and SLAs (Service level agreement) do not allow the database to downtime for a long
