The so-called non-relational database refers to a database that does not use the SQL language for data manipulation. Such a database does not have a fixed pattern for storing data, it does not support data table join operations, and can be easily scaled ou

Many people may feel familiar with the use cases in UML. If you ask a question about the use case, many answers are an elliptic in the use case diagram. Is the use case just an elliptic in the example diagram? Of course not. What is the nature of the

tests code constructs (White-box testing), tests code functionality (Black-box testing), maintains code integrity (regression testing), and static analysis (programming standard execution and metric metrics). Without complex settings, Jtest can immediately use and point out problems. If you use "design by contract" techniques to include descriptive information in your code, jtest can automatically establis

Usually we can use the robot framework to write interface automation use cases, but some sites do not do the front-end separation, the iterative process has a lot of repetitive test work, there is no interface to call validation, there are automated test requirements, how to do? At this point, the Web UI Automation of the deep pit is imperative. Robot is just an

represented by the variable K. According to the characteristics provided by the data, each data point is assigned to one of the groups in the K group by an iterative operation. In the figure below, K = 2, so that two clusters can be identified from the original data set.10 Interesting use cases of the K-means algorithm Executes the K-means algorithm on a data set whose output is: 1.K Center point: Each cen

A use case is a contract that represents the behavior of the system in relation to the people involved in the project. The use case describes the response of the system to requests from a project's personnel under different conditions. Depending on the conditions involved in the request and request made by the performer, the system executes a different sequence of behaviors, each of which is called a scene,

Although the size of the community is a less precise issue, at least 3,000 companies are using Cassandra in the production process. Over the past few months, we have learned more about applications that use Cassandra, and have come up with an attractive pattern in which more than 80% use cases can be grouped into these five types of applications. 1.
