The reason is that at the end of 2014, we saw Kingsoft's online malicious code analysis system "Fire eye" (https://fireeye.ijinshan.com /). I felt very fresh. I lost some samples I had collected, and the
row link in the database, row migration can severely affect the performance of the database. Therefore, we should try to eliminate the row link and row migration. Follow these steps to eliminate row and row links.
STEP1: Creating a data dictionary table chained_rows
The Data dictionary table chained_rows is used to receive analyze ... List CHAINED rows
: Orders created by the user are recorded (orders for goods purchased)
Order Schedule OrderDetail: The details of the order are recorded and information about the purchase of the goods
Product List items: Record the product information

location of the dictionary, and then each element in the buckets is a linked list. The element used to store the same hash, and then allocate storage space. So what we're faced with is that even if we create an empty dictionary, it comes with 2 arrays of length 3. So when the data processing is not long, it is prudent to use the dictionary as well, in many cases the use of arrays is also acceptable.2. Usag
will make all the elements in the previous set have the same originator as those in the later set, which will become the "sign" of these elements ". This idea is inspired by the female world, so women still play a role.This is called "parallel query", and "non-intersection. It can merge two sets and query whether two elements are in the same set. We have a very effective pruning: In recursion, we will turn all the generations that pass through the road into the sons of the root. Such a program
线性表中序号为i的数据元素为e返回原数据元素 public Object replace(int i,Object e)throws OutOfBoundaryException; //返回线性表中序号为i的数据元素 public Object get(int i) throws OutOfBoundaryException;}
Strategy configuration: (with the object type, there is a problem: int type and string type comparison)public interface Strategy { //判断两个数据元素是否相等 public boolean equal(Object obj1,Object obj2); //比较两个数据元素的大小 public int compare(Object obj1,Object obj2);}

You can take advantage of the version features of IBM Rational Focal point to generate snapshots for an element, including investment analysis data. When a new version is created, the current values of all properties are recorded. The Version property saves a list of all recorded versions.
Typically, the purpose of setting up a version property is to automatical

This is a more complex topic, generally divided into the primary, advanced, and specialized algorithm analysis three stages to learn, so we also need to be gradual.
