Url lookup is a bit more complex. It is used to find the "url" of the database to be connected. For example, if you want to search Baidu in a browser, you also need to provide a url. The url of mysql is as follows:
Jdbc: mysql: // localhost: 3306/mydb1
JDBC requires that the url format consists of three parts, separated by commas.
The first part is jdbc, which is fixed. The second part is the database

We classify the processed data into two types for feature extraction. One is the Primary Set, which is used to represent the original data; the second type is the Secondary dataset, which is used to represent the statistical data obtained from the original data analysis.
The experiment shares 258 feature attributes, including 180 feature attributes in the master dataset and 72 feature attributes in the secondary dataset.4.1 Primary Features Mismanagement Features: these five data Fe

The JDBC drivers for each type of DBMS are different. The same DBMS also has several JDBC drivers, such as Microsoft SQL Server's JDBC drivers, the JDBC driver officially provided by Microsoft and the non-open source JDBC Driver (jtds) are recommended, with few bugs and completely open source code. Currently, jtds only supports Microsoft SQL Server and Sybase.
Since DBMS and JDBC drivers are different, the
