Statements that work well with smaller datasets can behave differently when table sizes increase or multiple operations occur simultaneously.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eLearners may understand query syntax but find it difficult to explain why certain queries require more processing time than others.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eAnother challenge involves understanding how indexes influence data retrieval, how database engines evaluate query
