CLASSFCTION OF SYSTEM

ON BASIS OF WRKNG/OUTPUT:DETERMNSTC/PROBABLISTCON BASIS OF INTRCTVE BEHAVIOUR: OPEN/CLOSEON BASIS OF DEGREE OF HUMAN INTERVENTION: MANUAL/AUTOMATEDON BASIS OF ELEMNT:ABSTRACT/PHYSCL

COMPONENTS OF CBIS

• PEOPLE(USERS, PROGRMMERS)• COMP SYSTEM(H/W & S/W)• DATA• PROCEDURES• N/W

STEPS OF DATA PROCESSNG FOLLOWED BY CBIS

• COLLCTION OF DATA• INPUT OFDATA INTO INFO SYSTEM• PRCSSNG OF DATA USNG DATA PRCSSNG

S/W(WHCH MAINTAINS BUSNSS LOGCS FOR DATA PROCSSNG)

• PROCESSED DATA IS EOTHR STORED IN STRGE DEVCE &/OR CMMNCTED TO USERS AS OUTPUTS

CHRCTRSTCS OF CBIS

• PRE DEFNED GOALS• INTER RELATED SUBSYSTEMS• INTEGRTD SYSTEMS• COMMON GOALS

MAIN AREAS OF COMP BASED APPLCTIONS:

• FINANCE & ACCOUNTNG APPLCTION• MARKETNG & SALES• PRODN N MNFCTRNG• INVNTRY N STORE MGMNT• HR MGMNT

TYPES OF IS

• OSS(OPERATIO SUPPRT SYSTEM):..TPS+PCS+ECS

• MSS(MIS+DSS+EIS)• OFFCE AUTMTION SYSTEM(TEXT PRCSSNG

SYSTM+ EDMS+ELCTRNC MSGNG SYSTEM+TELECNFRNCG & VIDEO CONFRNCNG SYSTEM)

TPS(TRNSCTION PROCESSNG SYSTEM)

• COMPONENTS: INPUT+PROCESSNG+STORAGE+OUTPUT• TO MAKE A DATA SUITABLE FOR PROCESSNG INPUTS IS A 2

STEP PROCESS: CLLCTION/RECRDNG & CLASSFCTION/CONVERSION

• STORAGE HOTI H IN MSTR FILE & TRNSCTION FILE• OUTPUT REPRTS FRM A/CNG TPS CAN B DIVIDED IN 2

CATEGORIES:FINANCIAL N OPERTIONAL REPRTS• FUNCTIONS OF TPS: PROCESS LARGE VOLUME OF DATA• AUTMTION OF BASC/ROUTINE OPERTIONS• SOURCE OF INPUT TO OTHR SYSTEMS• EASILY MEASURBLE BNFTS

MSS(MIS+DSS+EIS)

• MIS MTLAB 3 ELMNTS:• MNGMNT+INFORMTION+ SYSTEM• MNGMNT(PLANNING+ORGANSING+INITIATNG

+CONTRLLNG)• INFO(MEANINGFUL CNTXT TO MNGMNT FOR

MNGMNT FUNCTIONS)• SYSTEM(ACHIEVNG OUTPUT BY CNNCTNG SUB

SYSTEMS BY INFO EXCHNGE)

CHRCTRSTCS OF AN EFFCTVE MIS• MNGMNT ORIENTED• MNGMNT DRCTD• NEED BASED• EXCEPTION BASED• INTEGRATED• COMMN DATA FLOWS• LONG TERM PLANNING• MODULRTY(SUB SYSTEM CNCPTS)• COMMON DATA BASE• COMPTERSED

MISCNCPTIONS BOUT MIS

• YE KWAL COMP SE RELATED H• MORE DATA MATLAB MORE INFO• ACCURCY IN REPRTNG IS OF PRIME IMPRTNCE

PRE REQUISITES OF AN EFFCTVE MIS

• DATABASE• QUALIFIED SYSTEM N MNGMNT STAFF• SUPRT OF TOP MGMNT• CNTRL N MAINTENANCE OF MIS• EVALUATION OF MIS
