2) software reuse is supported. Any two filters can be connected as long as the data suitable for transmitting between two filters is provided;
3) Easy system maintenance and performance enhancement: new filters can be added to existing systems, or old filters can be replaced by improved filters;
4) supports parallel execution: each filter is completed as a separate task, so it can be para

Think I graduated only MATLAB, and then led by the leadership of two weeks to learn R, one months to learn python, their own in the amateur learning Java,hadoop and spark, but also step by step, do not want to eat into a big fat. 12. What's the future? I have doubled my salary from internship to 5 times times, how do you say. If you only go to the money, do the sales, if you like the pure number, to do research, if you like to find something interesting from the
Because of the need to completely delete some of the data, remember that some storage devices with such an option: Replication n times to completely erase the traces of the original information, but Windows have any good tools to do this job? Search the Internet, find a lot of "file Grinder" "Super File Grinder", software and miscellaneous, let a person at a loss.

Two data recovery software are introduced: TestDisk and PhotoRec. Among them, TestDisk is mainly used to restore damaged partitions and save unbootable disks, while PhotoRec is mainly used to restore damaged data files, including documents, images, and videos.
Both TestDisk and PhotoRec support execution on Windows, Linux, Unix, Mac OS, and other systems. TestDis

Stumbled, I walked all the way, fortunately, never lost the initial feeling, from the initial beginner fun, to the fun of development, and then to today with the team is still interesting, I feel that I am looking for the life of the control, and then a plunge in, in the program, about her out, ah, very fun!
What is in life, I am in the process of imitating what to do, this thing let me creative constantly, in fact, is life to my freedom.

The most important thing is the E-R diagram and the details of each table.
Here I use the yitu software.
In a true E-R diagram, there should be no many-to-many relationship, and a one-to-one relationship, such as between students and cards. As I mentioned before, some people think they must follow the three paradigm completely, however, for specific business analysis,
