Tutorials | Chinese topic: whole-part relations ?????????? Content?????????? V 1. Object Whole-part Relationship V 2. Combination/partial relationship V 3. Inclusive/content Relationships V 4. Set/Member Relationships 1. Object Whole-part Relationship Class inheritance (class inheritance) and object combination (objects composition) are two key tools for software reuse (reuse). Class inheritance is the relationship between the parent and subcategory, for example,,"students" can be divi

in column_y, which means that it thinks all values have the same frequency of occurrence. If that happens, it's not a big deal. However, if some values appear more frequently than others (for example, if ' value_z ' occurs 900,000 times, which takes up 90% of all rows), then the optimizer cannot take this into account, thus generating an access plan that is not optimal. and distribution statistics can fill this gap. Distribution statistics can provide information on the frequency and distributi

Example: A high-speed road has 10 entrances, each entrance can only enter 1 vehicles per second 1, please ask 1 seconds up to a few cars. Tps=10 2, how long each car needs to respond. Reponse time = 1 3, change to 20 cars, can enter several per second. How long is the response time for each car? TPS = 10,reponse time = 1 (10 are first-class, divided into two equal parts, the average TPS (10/1+10/2)/2=7.5

Note that you do not need to nest containers unless necessary. nested layers may have performance problems in large projects.Models and Stores If You Preview now, you will find that the grid is empty and has four columns headers -- String, Number, Date, and Boolean. this is because we didn't bind our grid to a d

necessary to the real Mercedes-Benz car has a very good abstraction (of course, Mercedes-Benz car has a lot of series, here is not dead). That means if you're going to build a Mercedes, you need to benzcar this class (the Mercedes-Benz is a instance in memory).Then the abstract class is the abstraction of the class.How do you understand it? That means there are a lot of car manufacturers to define a specification (car Class), said to build a car will need to have engines, tires, audio equipment

(examples are simple and may not conform to realistic logic) The semaphore (non-binary semaphore) is not guaranteed to
