📚 I-SQL Antipatterns (Inguqulo ka-2025–2026) iyincwadi yesilabhasi enemininingwane ephelele eklanyelwe izitshudeni ze-BSCS, BSIT, Software Engineering, kanye neSayensi Yedatha, kanye nabafundi abazifundelayo abahlose ukuba umpetha womklamo wesizindalwazi ophumelelayo nezindlela zokubuza imibuzo. Lolu hlobo luhlanganisa ama-MCQ, kanye nemibuzo yokusiza abafundi bagweme izingibe ezivamile ngenkathi bakha amasistimu esizindalwazi aqinile futhi angalawuleki.

Ngesilabhasi ehlelekile, le ncwadi ihlonza imininingwane egciniwe avame kakhulu kanye namaphutha e-SQL, ichaza ukuthi kungani enzeka, futhi inikeza izindlela ezingcono kakhulu zokuwashintsha. Ihlanganisa ithiyori ngokufunda ngezandla ukuze kulungiselelwe abafundi izivivinyo, amaphrojekthi, kanye nezicelo zobungcweti.
