Something More About Concurrency Control

Time flies. 14 weeks have passed. Two weeks ago, Pro Koo hoped that we could use large amount of data to clarify concurrency control in a deeper level.Firstly, we should know some basic knowledge about concurrency control. In information technology and computer science, especially in the fields of computer programming, operating systems, and databases, concurrency control ensures that correct results for concurrent operations are generated, while getting those results as quickly as…See More

And I want to make a simple review of their lecture.They mainly divided “Transaction” into several parts: ACID properties, serializability, lock and lock-based protocols, Insert and delete operations, transaction and cloud computing.(picture1)…See More

A review of “Algebra of System: A Metalanguage for Model Synthesis and Evaluation”

When I first saw the paper’s title, I thought it might be useful not only for those scientists, but also for our daily work. I got to know that it shows us systems models as algebraic entities and formulates model transformation activities as algebraic operations, which are academically called “Algebra of Systems” (AoS) as a sort of modeling framework. The paper is divided into seven parts. And here I’d like to summarize it into four main parts as are shown below. …See More

About Cooperation

These days, all of us have been preparing the mid-term exams and mid-term presentation, during this period, I’m aware of something I seldom noticed before. It is called cooperation. In the past, I also know the word ”Cooperation”, we’ve done a lot of teamwork, we’ve finished various projects and so on. But on the current point of view, I must admit that the previous cooperation we’ve achieved can be only called “Division of teamwork”. We are in a team, but we do different work, and only our own…See More

review of Chen's paper

When I started to read this famous piece of work three days after class, I had already heard from classmates all kinds of complaints saying that they felt it a tough job to really grasp the general idea of the paper, let alone to raise personal view points. I, however, felt it smooth and enjoyable to read this renowned paper following the author’s train of thought and immersing myself in the storyline, and, with careful calculation and divergent thinking, not only develop an overview of the…See More
