Need this in a couple hours. Also, cannot increase price. Make three improvements to the attached program related to (see below). One of these improvements should be related to the use of thread. Also, ensure atomic operations for the threads occur concurrency ie., one thread cannot start until the other thread ends. The code needs to be readable with the new thread info, and ensure that the database closes after thread operations complete to prevent corruption, especially with thread operations.

Paper For Above instruction

In software development, especially in programs involving database operations and multithreading, ensuring data integrity, proper synchronization, and resource management are critical for reliable performance. The provided task highlights the necessity for three targeted improvements to an existing program, emphasizing thread management, atomic execution, and database handling. This essay discusses each of these enhancements in detail, illustrating how they can be effectively implemented to meet the specified requirements.

Implementation of Thread-Based Improvements

The first improvement involves incorporating multithreading into the program to enhance performance or responsiveness. Introducing threads allows parallel execution of tasks, which can be beneficial when dealing with time-consuming database operations or computations. However, the challenge is to manage thread synchronization properly so that one thread does not interfere with or precede the completion of another, thereby maintaining data consistency and program stability.

To achieve this, the program can employ thread synchronization mechanisms such as thread joins or mutex locks. Using a thread join ensures that the main process waits for the thread to complete before proceeding, making the execution atomic from the perspective of the overall program flow. Alternatively, mutex locks can prevent concurrent access to shared resources like database connections, ensuring that only one thread manipulates the database at any given time.

Ensuring Atomic Operations

The second improvement focuses on guaranteeing atomicity during thread execution and database interactions. Atomic operations are indivisible, ensuring that a series of actions are completed entirely or not at all, preventing partial updates that could corrupt data. Implementing atomicity can involve wrapping database transactions within transaction blocks, which either fully commit if all operations succeed or rollback if any fail.

In the context of multithreading, atomicity can also be achieved by making sure thread activities do not begin until critical sections are free, implemented through synchronization primitives. For example, using synchronized blocks in Java or atomic variables in C++ ensures that no two threads can perform conflicting operations simultaneously, thus maintaining data integrity and consistency.

Proper Closing of Database Connections

The third improvement emphasizes the importance of resource management, specifically closing the database after thread operations complete. Proper closure of database connections is essential to prevent corruption, resource leaks, or locking issues that may arise if the database is left open or improperly closed while threads are still executing.

This can be accomplished by placing the database-close logic after all thread activities have finalized, typically by joining threads in the main process before closing the connection. Moreover, employing a try-finally block or a context manager ensures that the database connection is properly closed even if an error occurs during thread execution.

Practical Implementation Example

Suppose the program is written in Java, with database operations using JDBC. The improvements might include:

1. Using Thread.join() to synchronize thread completion, making operations atomic from the program's perspective.
2. Encapsulating database updates within a transaction block to ensure atomicity, with commit() and rollback() appropriately called based on success or errors.
3. Closing the database connection only after confirming all threads have completed, which is achieved by calling join() on each thread before invoking connection.close().

This approach guarantees safe, readable, and efficient execution while fulfilling the task's requirements within the specified timeframe.

Conclusion

Through careful implementation of thread synchronization, transaction management for atomicity, and proper resource cleanup, the program's robustness can be significantly improved. These enhancements ensure that thread operations do not overlap improperly, data remains consistent, and the database resource is responsibly managed, thus preventing corruption and ensuring reliable performance. Adopting these best practices in multithreaded database applications is essential for producing stable and maintainable software systems.
