2. Database Bugs
The term “database bugs” might refer to issues or problems that can arise in database systems.
Common challenges or bugs related to databases include:
- Data Integrity Issues: Inconsistencies or inaccuracies in the data due to various reasons, such as incorrect updates or deletions.
- Performance Problems: Slow query execution, inefficient indexing, or poorly optimized database schema can lead to performance issues.
- Security Vulnerabilities: Improperly configured permissions, lack of encryption, or other security oversights can make a database vulnerable to unauthorized access.
- Concurrency Issues: Problems arising from multiple users trying to access or modify the same data simultaneously, leading to conflicts.
- Backup and Recovery Challenges: Difficulties in creating reliable backups or restoring data in case of failures.
- SQL Injection: A security vulnerability where malicious SQL code is inserted into a query, potentially leading to unauthorized access or data manipulation.
- Transaction Failures: Issues related to the proper execution of transactions, which may fail to commit or roll back correctly.
- Indexing Problems: Incorrectly designed or missing indexes can impact query performance.
