PR Summary

• Deprecated methods Earlier in the software design, multiple methods have been phased out as they are now replaced with better functioning equivalents. The outdated methods include AbstractSchema::normalizeRowKeyCase(), SchemaInterface::getRawTableName(), SchemaInterface::isReadQuery(), DbStringHelper::baseName(), and DbStringHelper::isReadQuery().

• Added methods to improve functionality New methods have been introduced to improve on the deficiencies of the deprecated ones. They are Quoter::getRawTableName(), DbStringHelper::isReadQuery(), and AbstractPdoConnection::setTablePrefix(). These methods bring with them enhanced functionality ensuring better, efficient results.

• Method enhancements Certain existing methods have seen changes to improve their performance or to fix the potential problems they could encounter. Amendments have been made in the Quoter::getRawTableName(), Quoter::$tablePrefix, and AbstractConnection::$tablePrefix property has also been fixed to prevent any issues.

• Simpler syntax A redundant symbol has been removed from the rtrim() function inside the DbStringHelper::baseName() method. This small change leads to simpler, cleaner code.

Please note, these above steps were taken to enhance our software by making it more efficient and simpler to use.
