Are sqlite user inputs dangerous?
SQLite user inputs can be dangerous if they are not properly sanitized or validated. If user inputs are directly used in SQL queries without any precautions, it can make the application vulnerable to SQL injection attacks. It is important to use parameterized queries or input validation to prevent malicious users from manipulating the database through user inputs. By implementing proper security measures, the risk of SQL injection attacks can be significantly reduced. **

What is the purpose of SQLite WAL and SHM?
The purpose of SQLite Write-Ahead Logging (WAL) is to improve concurrency and performance by allowing multiple readers to access the database at the same time as a writer. This is achieved by separating the write operations from the read operations, which reduces contention and improves overall throughput. The purpose of SQLite Shared Memory (SHM) is to allow multiple processes to share the same in-memory cache of the database, which can improve performance and reduce the need for redundant data storage. Together, WAL and SHM help to optimize the performance and concurrency of SQLite databases in multi-process environments. **
