Analysis of LoadRunner correlation and Web_reg_save_param methodFirst, what is the associationAssociation (correlation): During script playback, the client makes a request to make the correct request to the server by locating the left and right boundary values defined by the associated function (that is, association rules), finding the corresponding value in the contents of the server's response, and replac

associations and one-way associations. Bidirectional correlation: Two classes know that there is also a class of public properties and operations. One-Way Association: There is only one class that knows the public properties and operations of a second class. Most associations should be unidirectional, and one-way relationships easier to build and maintain, helping to find classes that can be taken. 5. Aggregation (Aggregation

I want to use simple template matching for image recognition.The pre-processed character picture is matched to a sample picture of A to J, respectively. The most significant results indicate that the character picture can be identified.In practice, I used the OpenCV matchtemplate () function, but I didn't get the effect I wanted.The function of Matchtemplate () is to search for the specified template in the image, if the template is intercepted from the image to be searched, it will have a good

classes, and dependencies are always one-way. A dependency represents a class that relies on the definition of another class. In the following example, class A relies on class B, C, and D.@interface A:nsobject-(b*) GETB: (c *) C:(d *) d {e *e = [e new];b *b = [B new];}@end3. Association:A reference relationship between objects, such as the relationship between a customer class and an Order class. This relationship is typically expressed using the properties of the class. The two classes involve

These three words are related. Correlation has three layers of meaning, but also Taobao search rankings of the three-layer filtering rules. The first layer is the search relevance, that is, only the title contains the search words of the baby is displayed, the oth

Content of this chapter: Apriori algorithm frequent itemsets Generate association rules to generate Association rules found in polls Finding hidden relationships between objects from a large-scale data set is called Association Analysis (Association analyst) or Association Rule Learning (Association rule Learning). Searching for different combinations of items is time consuming and computationally expensive, and brute force search does not solve this problem. Use the Apriori algorithm to solve t

relate to the World Cup scoring players in the club's performance, to the first form of association, first know Ronaldinho's ID number, and then find the corresponding club performance. Table 1, a row of data to the corresponding to the 1 columns of data in table 2, table 2 of the 1 columns of data to the corresponding table 1 of the 1 rows of data, in the two large tables in the million bar, this association cost is quite high. Although the two tables conform to the good paradigm, the

one row of data, As a result, data independence is maintained."Not good paradigm, associated design examples"If an incorrect paradigm, the associated design raises the cost of the association, for example, if the cost of both tables is large, there will be a significant cost problem in connection with the equivalent and not the equivalent. If the goal of the World Cup is linked to the player's performance in the club for a season, such as goals, fouls, steals, and so on, and the data is in a la

The view model is more like a table virtual table, and the view contains a series of column and row data with names. However, the view does not exist in the database as a stored set of data values. Row and column data is derived from the table referenced by the query that defines the view, and is generated dynamically when the view is referenced. The view acts like a filter for the underlying table referenced in it, which is what the thinkphp manual says.In fact, the view model is the MySQL mult

Here's a second way to implement a one-to-one correlation mapping, the unique Foreign Key association.Unique FOREIGN Key Association: A Foreign Key association, which is intended to be used for many-to-one configurations, but can also be used to represent an affinity relationship if a unique limit is added.A unique foreign Key association is also used in two ways, one-way and two-way. The object model is consistent with the single-direction associated
