A reminder to all GMS students. Start learning to use relevant technologies I mentioned in class today. You will need them every day. More specifically, the earlier you can set up your infrastructure, the faster you will be able to get into a proper learning mode.

As we discussed today, the "Challenge" will be conducted by students next week as a group exercise.

Given an image of my choice, and choose an object in the image, how to move that object to another place in the image? How to stretch and shrink it?

Those problems can be well solved by Affine transformations.Making it more concrete, my job is to rotate an object of my choice 30 degrees counterclockwise, translate by a distance, and scale of 0.5.

Firstly, load an image and show it in a window. Choose a rectangle area as ROI by mouse clicking. Then do…

With the continuous expansion of a system，the reliability of a system becomes more and more  important. There is one thing that must be taken into consideration --- concurrency control. Using our project as an example, there may be multiple administrators trying to write to the database. That is to say, we have to run transactions concurrently to meet their performance requirements. Thus, without concurrency control our plugin can neither provide correct results nor maintain their databases…

As recommended by Professor Koo, <beautiful data> was chosen as the sample of well written document for our final reports.

O'Reilly Media, the author of this book said that, “In this insightful book, you'll learn from the best data practitioners in the field just how wide ranging and beautiful working with data can be. Join 39 contributors as they explain how they developed simple and elegant solutions on projects ranging from the Mars lander to a Radiohead…

It is time to summarize what I have learnt in database course in this semester. Frankly speaking, this is one of the courses which have exerted most stress on me. However, it is also the most unique and irreplaceable course I have ever taken, because I have acquired not only basic knowledge concerning database, but also study skills and creative ideas in various…

Summary Of This Semester

        A busy but meaningful semester has come to the end as well as the database course. During this course, I not only learnt the database knowledge and skill…

The following SQL codes are used to select personal information that is inquired. The student ID and the inquired time of participation are typed in by users. The information of time, total score and score of each type of sport earned by the student during the month is returned.

I have written a blog on the original data model design of our plug-in, but more improvement has been made later. I’d like to summarize the improvement here.

Improved E-R Model and Normalization

This semester is finally over. After several tough final exams, I can have a rest and make some conclusions of this semester. I have to say that the database course is the most impressive course in this semester and I learned a lot in this course other than the knowledge itself.

First of all, database course shows us a new way of learning. Instead of the teacher-student mode, we learn knowledge by a book-student-student mode. From my stand point, this study mode has both its advantage…

At the end of the semester, I feel it necessary to review what I have learned during the whole course. I am improved a lot in three aspects, i.e. concepts, techniques and view. Then I will talk about each of them in terms of what exactly do they indicate and how I feel improved in them.

  “Concepts” is really a big concept. In the semester, I have met with countless new things never…

I just wandered whether there is a method of combining the computing power of a high-level language like C/C++ and the database manipulation capabilities of SQL a few days ago. But now I find the answer, embedded SQL. We can use embedded SQL to execute any SQL statement from an application.

The first technique for sending SQL statements to the DBMS is embedded SQL. Because SQL does not use variables and control-of-flow statements, it is often used as a database sublanguage…

         Everything has its end and so is the database course. But the final lecture for the reports of our plug-ins doesn’t mean the end of learning database – data are everywhere in life and what the most important is that we should know how to use things we learned from the course after class and even till our life.

         Though the number of blog entries is enough before the final-exam weeks comes, it is still necessary for me to make an additional blog at the end of the term…
