Many LANs are powerful (high speed) and has low error rates, many applications do not need the data integrity provided by OSI. Hence this can make project quality management hard to implement during the project management life cycle. There are times when the team ignores necessary quality parameters such as consistency, reliability and standardization. Success depends on the extremely high technical skills of the developers. This method cannot be a success if the team is not sufficiently motivated and nor is unable to work cohesively together. This method may not be useful for large, unique or highly complex projects. Shared Lock, users can view the data in a read only format, users are unable to change or update the data, an example of a shared lock, could be a SELECT statement. This ensures that the data can only be modified by one user at a time, avoiding multiple changes. There are two different locks that can be applied: Exclusive, while the user has access to the data, the row will become locked - allowing the user to insert, update or delete records. Advantages and Disadvantages of.Ĭoncurrency will allow simultaneous access of the same data, which can be accessed by different users. Incremental Model is a process of software. Incremental Methodology is a process of software engineering development. Since concurrent engineering practices decrease the time spent in the design and development. Even a CPU with a pipeline may be said to be executing several instructions concurrently.Ĭoncurrent engineering. Multiple processes or threads executing on different processors may be said to be 'truly concurrent,' since they can be running instructions at the same time (without the need of a CPU scheduler).

Multiple processes or threads executing on the same processor are said to be running concurrently. This is a very loosely defined term and may refer to multiple things. Concurrency, in computing, refers to when multiple path of execution (threads or processes) are running at the same time.
