of the database, consistency, do you like to use triggers or self-writing business logic? Why?A: A trigger is a special type of stored procedure that is triggered primarily by an event to be invoked automatically by the execution of the trigger. The stored procedure can be called by the name of the stored procedure.As far as possible with constraints (including check, primary key, unique key, foreign key, non-null field) implementation, the efficiency of the best; second, with the trigger, this

The basis of probability theory Suppose X and y are random variables defined on a finite set of x and Y respectively. Joint probability P (xi,yi) p (x_i,y_i) is the probability of X=xi,y=yi x=x_i and y=y_i. Conditional probability P (xi|yi) p (x_i \vert y_i) is the probability of Y=yi y=y_i when X=xi x=x_i. If there are P (x,y) =p (x) p (Y) p (x, y) = P (x) p (y) in any x∈x,y∈y x \in x, y \in y, then the random variable x and y are statistically inde

computationally complex, they can still measure other algorithms as a criterion for optimal decision making. Bayes Law In machine learning, we are usually interested in determining the best assumptions in the hypothetical space H given the training data d. The so-called best hypothesis, one approach is to define it as a priori probability in the given dataset D and h of the different assumptions of the knowledge offending possible (most probable) hypothesis. Bayesian

the nonlinear correlation coefficient based on the measurement criterion of mutual information.Consider a random variable X with n possible results whose probability distribution is P (x=xi) =pi,i=12,..., N. Then its information entropy is defined as H (X) =−∑i=1npilogpi.Suppose that this joint probability of the stochastic variables (x,y) is Pij, the two-dimensional entropy of (x,y) isH (x,y) =−∑i=1n∑j=1mpijlogpijSuppose that the marginal distribution of X and Y repectively are pi and Pj˙, the

1. Does the user benefit from the same appearance? Not so. Most users use only a single browser, so they view the site in just one way. They don't care what the site looks like in other browsers. 2, the same appearance can better maintain the company's brand image? Not The company's brand is established through style, color, trademarks and logos used and representations. 3. Sites encoded using WEB standards can be browsed in old browsers and new browsers. Just in old browsers, sites don't look

launched the "Industrial design" of the "design" of the word, leaving more tactfully smooth, let a person slightly a smile moved. Are you "designing" "framing"? "User-centric" thinking has been advocated for a long time, to meet the needs of users, become the paramount goal and motivation. But will the needs of users be satisfied? Not just the budget for business-design operations, but the need to consider users as the same as US: are all the needs really to be met? The demand

Common to the online blog has the wrong theory, including many friends around have agreed that "accessibility (accessibility) is for people with disabilities," the view. In fact, in the field of Internet technology is far more than that simple, summed up there are three aspects: Coping with the normal browsing requirements in extreme environments; Structure, performance, behavior across the terminal Cross-platform compatible support; Ensu

They took out n stones and put them in a column. The game, each time only from the left a row of stones at the beginning, take one or two stones, the goddess let Xiao Xin take first. When the last one is finished, there is no stone even if he wins the

more high-level code on the call stack needs to process the interrupt after the irrevocable task ends. Listing 6 shows a method that waits for a blocking queue until an available item appears in the queue, regardless of whether it is interrupted or not. For the convenience of others, it restores the interrupt state in a finally block after it has ended, lest it deprive the caller of the interrupt request of the right. (It cannot restore the interrupt state at an earlier time, because that will

In life and work, we often lock a focus on words "innovation" Often hear people talking about the importance of innovation, how to innovate. In order to innovate we are also in the design process to brainstorm, thinking about how to get more dazzling, cooler and more unexpected design, so as to achieve innovative purposes. At the same time, we also feel that such innovation depends more on personal inspiration, inspiration is the idea of a flood of ideas, out of the way, the inspiration is gone

What can a space do in website optimization? It is often defined as a "separator" concept, used in headings, keyword tags, and description tags to make it easier for search engines to match split keywords. But what else can "space" do? Here binary is to say: "Space" can do hot keyword optimization, do you believe it? It is not difficult to discard the long tail theory and simplify the keyword, and make other popular word optimization. Below, we will m

Recently in the chapter on the graph theory of discrete mathematics, here is my classification and summary of some important concepts of the graph. Describe the concept of relationships Association--used to describe the relationship between a point and an edge, which simply means that the edge is made up of those points and is associated with those points. The correlation matrix is a matrix that records the number of points in the Edge Association.
