Concurrency Control

The simultaneous occurrence of two or more operations is called concurrence and the situation is called concurrency. In concurrency, the function of one operation can affect the function of the other and put data integrity at risk. Hence, management for the control of concurrency is required. The management or controlling system in the Database Management System (DBMS) that coordinates concurrent access is called the concurrency control system.

Computer Science A system call in an operating system is typically a function call that traps to the kernel. However, there are also library calls that are functions that do not directly trap into the kernel, but may invoke system calls that do. In MINIX, there is a corresponding library call read that always invokes the system call. In UNIX, there are also several other library calls---getc, fgetc, getchar, for example---that also input data. Describe the difference between the MINIX read library call and these functions. How do you think these functions (getc, fgetc, getchar) perform data input? Do they always need to ultimately trap to the kernel? Why or why not?
