In　contemporary　community　management,　digital　community　management　systems　are　of　great　importance.　A　database　system　for　community　management　maintains　the　generated　data　and　provides　efficient　and　organized　services　to　the　residents.　In　this　paper,　a　SQL-based　community　information　management　database　system　is　developed,　and　the　design　and　implementation　of　this　community　information　management　database　are　studied.　The　database　stores　and　manages　information　about　buildings,　apartments,　residents,　parking　lots,　cars,　equipment,　resident　feedback,　etc.　in　the　community.　At　the　same　time,　this　paper　has　also　designed　a　relational　model　between　entities,　so　that　this　paper　can　sort　out　the　attribute　relationships　between　entities,　and　then　design　SQL　statements　to　query　the　data　of　the　entered　entities,　to　achieve　an　efficient　data　search.　In　addition,　the　paper　also　performs　some　manipulations　of　the　developed　database　using　SQL　language　which　helps　the　residents　and　management　people　to　maintain　the　community.　To　sum　up,　the　database　designed　in　this　article　can　effectively　store　community　data　and　play　an　important　role　in　the　normal　operation　of　the　community.　©　2022　IEEE.
