SteveConcurrent control is a type of control mechanism that focuses on managing activities as they happen in real time. It involves monitoring ongoing processes to ensure that they are progressing according to plan and taking corrective actions immediately if any deviations or issues are detected. By implementing concurrent control, organizations can improve efficiency, identify problems early, and prevent them from escalating into larger issues.

Why are semaphores used?
In computer science, a semaphore is a protected variable or abstract data type which constitutes the classic method for restricting access to shared resources such as shared memory in a multiprogramming environment. Hence as a security feature it is largely used Kushal P. Bathija
What is concurrent schedule in dbms?
A concurrent schedule in DBMS refers to multiple transactions running concurrently without interfering with each other. This allows for improved performance and efficiency in handling multiple operations simultaneously. However, it requires careful management to ensure data consistency and avoid conflicts such as race conditions.
What is View Serializable in DBMS?
View Serializable is a correctness criterion in database management systems that ensures that the final result of executing concurrent transactions is the same as if they were executed one after the other. This property helps maintain data consistency and ensures that the database remains in a consistent state despite concurrent transaction execution. Transactions are said to be view serializable if their interleaved execution produces the same results as if they were executed sequentially.
How database provide informatiom to multiple users?
Databases allow multiple users to access information simultaneously through features such as user permissions and concurrent access control. Each user is granted specific levels of access to the data, ensuring data integrity and security while allowing for collaboration and sharing of information. Additionally, databases can handle multiple queries and transactions at the same time, allowing various users to interact with the data concurrently.
What is the scientific name of pesticide?
If you know the name a search on the web will tell you the active ingredient. That's hard to answer without knowing which one you are referring to. There are many different active ingredients currently in use.Pesticides may also be broken down into many different categories:Algicides or algaecides for the control of algaeAvicides for the control of birdsBactericides for the control of bacteriaFungicides for the control of fungi and oomycetes is a very badHerbicides (e.g. glyphosate) for the control of weedsInsecticides (e.g. organochlorines, organophosphates, carbamates, and pyrethroids) for the control of insects - these can be ovicides (substances that kill eggs), larvicides (substances that kill larvae) or adulticides (substances that kill adults)Miticides or acaricides for the control of mitesMolluscicides for the control of slugs and snailsNematicides for the control of nematodesRodenticides for the control of rodentsVirucides for the control of viruses
