Mayelana nalolu hlelo lokusebenza

📘Amasistimu Wesizindalwazi (2025–2026 Edition)

📚I-Database Systems iyincwadi yesilabhasi ebanzi eyenzelwe i-BSCS, i-BSSE, i-BSIT, izitshudeni ze-Data Science, kanye nabafundi abazifundelayo abahlose ukuba ingcweti kwezimiso eziyinhloko kanye nokusetshenziswa okungokoqobo kokuklama nokuphathwa kwesizindalwazi.
Lolu hlobo luhlanganisa ama-MCQ kanye nemibuzo yokuqinisa ukuqonda komqondo nokuhlinzeka ngolwazi olusebenzayo lwesizindalwazi kusetshenziswa izinkundla ze-SQL ne-RDBMS.

Incwadi ithatha abafundi ukusuka kumamodeli edatha ayisisekelo kanye nokwenza kube jwayelekile ezihlokweni ezithuthukile njengokuphathwa kokwenziwe, imininingwane egciniwe esabalalisiwe, nezinhlelo ze-NoSQL.
Igcizelela kokubili ithiyori nokusebenza, inika abafundi amakhono okuklama, ukubuza, ukuvikela, nokuthuthukisa imininingwane yolwazi ngempumelelo.
