All engineering problems in the field of software development are ultimately derived from one problem: What if the code size is large?For CSS, the core issue caused by the increase in code size is naming conflicts.The methodology of resolving naming conflicts is modular, which evolves various modular schemes around this methodology.First, the naming of the modularThe basic idea is to ensure that the global space under the domain name does not conflict

adjustment, and whether it works, depends on how well you know the CBO and the execution plan.I used to mention in 20#: "Method 1: Reduce the resource consumption of the target SQL statement" to shorten the execution time, which is the most commonly used SQL optimization method. The core of this approach is either to reduce the resource consumption of the target SQL statement by overwriting the SQL without changing the business logic, or to reduce the resource consumption of the target SQL stat

The most widely used software engineering methodologies are traditional methodologies and object-oriented methodologies. The traditional methodology is not only traditional but also not suitable for the contemporary place, then whether it has the application value in the present age?Traditional methodologies are also known as life-cycle methodologies or structured generics. It uses structured technology (structured analysis, structured design, and str

We said that, unlike heavy-duty methods, which focus on planning, processes, and intermediate products, agile methods focus more on people and communication. People and communication are always the first, and planning, processes, and intermediate products are just a means to ensure communication and achieve goals. This does not mean that the Plan, process, and intermediate product are not important, but they cannot put the cart before the horse.Note: We define intermediate products as documents,

SQL Server Performance Tuning methodology and common tools, SQL Server Tuning In earlier articles, we mentioned the DETECT methodology in Performance Tuning. Here we will briefly review the DETECT methodology. Discover the problem: found the problem Lead e the conditions: Explore causes Track down possible approaches: provides possible solutions Execute the most

brings potential risks to the successful implementation of the project. What causes this problem? Is there a feasible solution to this problem? A complete project management system is inseparable from the enterprise's industry background and business fields. The root cause of the above problems lies in the intersection of project management and business processes, the project management process is complicated and uncontrollable, which is the root cause why a set of methods cannot be applied to

Author: LuckEmail: webmaster@chinaspx.comWhen designing JSP projects, the current methodology provides more limits rather than help. According to Mr. Kochmer, the key to successfully running a JSP project is project management rather than design..Contrary to the general idea, the best design methodology is not the formal one when running a project. Most design methodologies are bloated and impractical. If a

ITIL: Full name: (Information Technology Infrastructure Library ). What is it? It is a methodology and best practice for improving IT services, helping it service providers provide high-quality services that meet requirements at appropriate costs. But in fact, this methodology is not only used for IT services, but can be used for reference by other service providers. I. Core and essence of itil. The core

Label: Use sp bs user Method software simple nbsp InternetZhou Hongyi, my Internet methodology.I recently read the Internet methodology book of Lao Zhou. I feel that the book is well written, and the style is not like a normal book, such as a biography or a record. After reading this, I feel that Zhou Hongyi and 360 are really not ordinary today.1. Internet thinkingFocus on focus, fast iteration, small-step jogging, continuous release of new features

Program Development Methodology Program Development is a technical activity. Only by accumulating experience and reflecting on the past can we gain income on an occasional basis, so as to improve our development methods and work efficiency. Writing programs is not physical activity. Generally, there is a problem with writing a program because the preparation is not enough. In fact, writing a program has a rumor: thick accumulation. If you have a clear

society. The trajectory of human society in time and space is" History". If a role is also a dimension, then we combine the time latitude and scenario dimensions. This is a methodology for analyzing things. If we use this methodology to analyze the business, that is, business analysis three-dimensional (role + scenario + time) theory.

1. Industry Data Mining methodology2, in the work, we carry out the guidance method of data mining implementation:Eight-Step application modeling: Business understanding, indicator design, data extraction, data exploration, algorithm selection, model evaluation, model release, model optimizationStep One: Business understandingCommon misunderstanding: Many people think that there is no need to identify problems and goals beforehand, as long as the data using data mining technology, and then the a

Barbara Minto's "pyramid Principle" is a controversial book, a lot of people scoff at this book, there are many people to this book greatly praised. people who scoff at the idea, is not the middle school argumentative writing method, "total-the total", make such a divine knife, so complex, and a simple reason to write too obscure, wordy, read very laborious. The Grand prize people think that "pyramid principle" is a very good tool, pyramid principle seems nonsense, but it is really a great princ

Modern microprocessorsThen there is the methodology of learning:How do you learn these two courses? What books do you read? here I'm going to tell you a general way to the A

Team design is an important practice in Agile Methodology. The team we are talking about here is not a plural person. A group of people is a group and cannot form a team. To become a team, you have to do a lot of work.The reason why we consider architecture design on a team basis is that software development is not a personal task, especially architecture design. A single individual's thinking cannot be considered properly, and his or her knowledge ca

Creating good products requires a conceptual framework for more general needs. If the product manager just put some ideas, processes, prototypes, concepts to stir, it is not to appear that our work is very simple, even some low? In fact, this is the initial/final impression that most product managers give to the team. Remember the words in the book IA: Good research is to ask the right question, choosing the right question needs to build a conceptual architecture for the broader environment. Thi

Label:The first step in the optimization methodology is to find out at the instance level what type of wait is taking up most of the wait time, which can be queried by the dynamic management diagram (dmv,dynamic management view) sys.dm_os_wait_stats Running the query will return the wait information in your system and sort by type. SELECT wait_type, waiting_tasks_count, Wait_time_ms, Max_wait_time_ms, Signal_wait_time

Label:I recommend an optimization theory that uses top-down. This approach begins by analyzing the instance-level wait time, which is continuously refined through a series of steps to find out which processes/components are causing a lot of waiting in the system. Once you find these annoying processes, you can focus on optimizing them, which is not the main step of this methodology: 1. Parsing instance-level waits 2. Associating waits and Queues 3. Id
