CSCE5360 –Reading Assignment Number ___2____ Your Name: Mounika Pandhiri Paper title: Fast Serializable Multi-Version Concurrency Control for Main-Memory Database Systems You should understand what the problem(s) (or issue(s)) that the paper is addressing, and their solution(s), which must be described in the reading assignment by your own words. Please do not copy and paste from the assigned paper. 1. Clear statements of the problem(s) (or issue(s)) that the paper is addressing (upto 2 pages only): Providing Serializability is one of the most common feature of the present day databases. The most important transaction property among ACID properties of transactions is the Isolation. Isolation gives a misconception to each transaction that is independent of other transactions and is executed separately whereas in reality, the transactions are executed concurrently in background. In order to provide isolation, the concept of serialization is used by DBMS. But the actual problem lies in implementing the serializability efficiently. Many systems use Snapshot Isolation, which is an alternative for serializability. But it does not provide full serializability and in order to incorporate serializability in to existing snapshot isolation results in higher costs. The most common way to implement serializability is to use the technique of two-phase locking where the read and write locks are maintained for data items. Using this locks helps in executing theShow MoreRelatedTimetable Management System Using Java7535 Words   |  31 PagesBAM 752 Introduction to Softwares Computer Organization and Architecture Discrete Mathematics Business Communication Total Credits Semester – II S.No. Course Code Course Name 6 COMP  723   Operating  System   7 8 9 10 COMP 724 COMP 725 COMP 726 MAS 661 Data Structures using C++ Information System Analysis and Design Web Technologies 11 BAM 753 Essentials of Management Computer  based  Numerical  and  Statistical   Techniques   Total Credits Semester – III S.No. Course Code 12 13 14 15 16 17 COMPRead MoreObject Oriented Programming41739 Words   |  167 Pagestypes and they are: byte, short, int, long float, double boolean char 6)What is an Object and how do you allocate memory to it? Ans: Object is an instance of a class and it is a software unit that combines a structured set of data with a set of operations for inspecting and manipulating that data. When an object is created using new operator, memory is allocated to it. 7)What is the difference between constructor and method? Ans: Constructor will be automatically invoked
