MANAGING THE DATA Sasaran Pembelajaran Mata kuliah : CSM-211 , Management Support System Tahun Akademik : 2012/2013 MANAGING THE DATA Sasaran Pembelajaran The student can making the diagram / schema data/information display of EIS 12-1

Objectives The data management challenge : Other Development - Data Development - Data Management Issue - Data Warehouse Other Development 12-2

DATA MANAGEMENT Data / Database is the primarly important of EIS. Source Data : Internal and external (hard-data and soft-information) Source Internal Data from database organization to extraction (transformation) tobe database EIS Source Soft information from external (news, opinition, prediction, forecasting 12-3

Example data source 12-4

DATA DEVELOPMENT To echance EIS have shapening the focus, following questions of data development : What portions of what reports are of interest How is it used Is other information related to it What are the correlations Would a different summary or format be better ? Is the level of detail appropriate Is the update frequency sufficient What is the confidence placed in is accuracy Is it timely Is it complete 12-5

SOURCE DATA Internal : organization database, needs exstraction (transformation) example : Oracle, Excell spreadsheet External : Needed software /program to filtering and relation by internal data internal to consolidate display example : data stock market, news service, competitor, Key customer, statistics 12-6

DATA INTEGRATION Data integration is combining source data to development with technical and business challenges. The technical, develop new technical to additional new display of EIS. And Data from source can combining to be one information comprehensive by user perspective 12-7

LINK TO OTHER APPLICATION EIS can link to other application program to getting result by potentialy better approach Example : Combining DSS Application, use information by email, group support software 12-8

DATA MANAGEMENT ISSUES Integrity Ownership and sharing Security Storage 12-9

Data Management Issues Integrity : 12-10

Ownership and Sharing Getting data EIS, procedure can include the following : Discussing the purpose of data and how it is to be used in EIS Reviewing the initial screen using data prior to placing online to executve users Jointly developing data extraction processes to minimize disruption to database or processes Notifying data suppliers of any abnormal values obtained Providing data supplier with hardcopy of EIS screen that use data ( if there are not online to EIS) 12-11

DATA WAREHOUSES Need of Data Warehouse Benefit of Data Warehouse Bulding data warehouse 12-12

Data Warehouse 12-13

SOFT INFORMATION Hard information : All data that getting from convensional method Example : financial report, sales order, inventory control. The Information reporting by schedulling, as user requirement. The Information produce by management database, and needed to lower management 12-14

Characterics Information 12-15

Perbedaan Hard dan Soft-informasi -------------------------------------------------- 12-16

The collection soft information Method The Question to collection soft Information : What the soft information of EIS ? How to entry-data ? What information provide to the User What soft information that not provide in EIS ? What reason ? What application to use by soft information ? What decision that influence soft information? How soft information influence value of EIS ? What the Factor that influence soft information ? In the future, what soft information that needed ? 12-17

LEGEND Rumors, gossip, hearsay 9,4 % Opinion, feelings, idea 15,6 % Prediction, speculations, forecasts, estimates 78,1 % Explanation, Justification, Assessments, interpretations 65,6% Schedules, Formal Plans 50,0 % News reports, industry trends, external survey data 62,5 % 12-18

Category of Soft Information 12-19

The Reason needed soft information Executive need soft information Organization culture impact needed soft information of EIS Executive do not commitmen to provide soft information of EIS Soft information can increasing attention from critical issue Soft information can increasing organization development Soft information can give additional industries variation Soft information provide competitive data to increasing value added Soft information donot always in the EIS 12-20

The Reason needed soft information Value soft information depend on timing Additional Quality and Quantity soft information can increasing supporting of Staff Soft information can increasing value of EIS Organization can increasing Quantity and Quality soft information Identification source, increasing value of soft information Provide soft information by EIS defend of technologies Prediction, Forecasting, estimation can provide enter to soft information 12-21

Technologies Process Soft Information 1. Text based document - new stories - e-mail - letter - report 2. Commercial database Robotic, monitoring the data source. The robot can give signal and information to send for soft information, if there are modify and change significanly.. ============ thanks 4 your attention =========== 12-22
