Since joining Ali began to contact these words, the first to listen to the boss what the strategy will be, our mission and vision is what. And so on, but always to the specific meaning of these words no concept, Ms these things away from me, with the passage of time, oneself also began to open strategy meeting, but some doubts always can not straighten out, until a soft was business-to-business acquisition,

First to see the background of the integration settings, some integration strategy can be used after
policy mode (strategy): It defines a series of algorithms, encapsulates each algorithm, and allows them to be replaced with each other. The policy pattern allows the algorithm to change without affecting the customer using the algorithm. (Original: The Strategy Pattern defines a family of algorithms,encapsulates each one,and makes them interchangeable. Strategy l
Strategy (Policy) Pattern is translated into a Policy mode. It is one of 23 modes in Gof's classic design mode. This article will reference the actual project scenario to use the policy mode to transform the actual project, to illustrate the purpose of the Policy mode.
The following uses Strategy instead of Strategy (Policy) Pattern.
The core of Strategy:Strategy
Definition of the policy pattern: Define a series of algorithms and then invoke them according to the actual situationAn episode: Recently in the process of the project took over a more complex requirements, because it is the old project with a new framework refactoring, so you can see the previous code, draw the essence of the previous code, reuse some of the code available, so that they write a half-day. Of course, this topic is the strategy mode, w
Some friends in my blog home that post the top article said the following message: "How to make a keyword strategy when the website is online, for example, what keywords should be formulated in the prophase, what key words should be formulated in the middle and later, and how to formulate the strategy of keyword optimization in different periods, to achieve a best optimization
Strategy Carding methodZhangStrategy is always in the "think" and "say" stage, people can not do strategy, can only implement strategy. The whole business process is the process of executing the strategy. The enterprise strategy can be made clear only if you think clearly. T
1, whether it is the choice of pessimistic locking strategy, or optimistic locking strategy. If an object is locked, the object will be controlled and affected by the lock. If the lock is an exclusive lock, then no other session can modify it.2, the choice of pessimistic locking strategy, or optimistic locking strategy
Overview
Define a series of algorithms, encapsulate them one by one, and make them replaceable. This mode allows algorithms to change independently of customers who use it.
Applicability
1. Many related classes only have different behaviors. "Policy" provides a method to configure a class with one of multiple actions. 2. Different variants of an algorithm are required. 3. algorithms use data that customers should not know. Policy modes can be used to avoid exposing complex algorithm-related data
This article describes the container and layout strategy for the UI interface. Mainly from the theoretical point of view of the principle and implementation of ideas, and contains a number of container sample map.
This article is written in February 2016, is published in the blog and share with you. The original text is the work need to do research, blog based on the original draft, and do a certain simplification.

Hibernate's search strategy is divided into three types1 class-level retrieval strategy, operating level in a single table, without implicating other tablesThe element's Lazy property is true or false, and the Get () method of the Session and the list () method of the Query always use the immediate retrieval policy at the class level if 21-to-many and many-to-many search strategies (in fact, the set tag of
The policy pattern defines a series of algorithms, encapsulates each algorithm, and allows them to be replaced with each other, and the policy pattern makes the algorithm independent of the customers who use it. The policy pattern enables these algorithms to change independently when the client calls them, which is a behavioral patternThere are three objects in the policy mode :
Environment Object (context): a reference to an interface or abstract class defined in an abstract policy is

Skilled use of the idea of inheritance: to find the application of the same, and not easy to change things, to extract them into the abstract class, let the subclass to inherit them, the idea of inheritance, but also convenient to build their own logic on the results of others. such as ImageField extends JTextField; skilled use of the idea of the interface: Find out where the application may need to change, separate them out, do not mix with the code that does not need to c
1. The concept of divide and conquer
Divide and conquer is an algorithm that uses recursion to solve problems, the main trick is to divide a large complex problem into multiple child problems, which can be used as termination conditions or solved in a recursive step, and the resolution of all the child problems together constitutes the solution to the original problem.
2. Advantages and disadvantages of divide and conquer
A divide-and-conquer algorithm usually includes the invocation of one o

The strategy pattern is very important in the design pattern and may be the most important pattern in the modern object-oriented design.It is used to create pluggable, replaceable, reusable components.For a complete and simple description of the policy pattern, the following code shows a very simple example.

MySQL allows the scheduling characteristics of the statement to be affected, which enables queries from several clients to collaborate better so that a single client is not locked out for too long. Changing the scheduling feature also ensures that specific queries are processed faster. Let's take a look at MySQL's default scheduling strategy, and then see what options are available to change this policy. For the purposes of the discussion, it is assum
