Outline Materi Data Resource Key Principles In Managing Data Categories of Information Processing Asset Management Functions Data Ownership Data Administration Tools for Managing Data Infrastructure Management

THE DATA RESOURCE DATA A MAJOR ORGANIZATIONAL RESOURCE MANAGE DATA & KNOWLEDGE AS STRATEGIC RESOURCE DATA ASSET ONLY IF AVAILABLE WHEN NEEDED RESPONSIBILITY OF EVERY USER- MANAGER *

KEY PRINCIPLES IN MANAGING DATA 1.NEED TO MANAGE DATA IS PERMANENT 2.DATA MAY EXIST AT SEVERAL LEVELS 3.KEEP APPLICATION SOFTWARE SEPARATE FROM DATABASE *

KEY PRINCIPLES IN MANAGING DATA 4.APPLICATION SOFTWARE CLASSIFIED AS TO HOW THEY TREAT DATA: Data capture, data transfer, data analysis & presentation 5.APPLICATION SOFTWARE CONSIDERED DISPOSABLE 6.DATA SHOULD BE CAPTURED ONCE 7.SET STRICT DATA STANDARDS *

DATA PYRAMID MANAGERIAL CAPTURE SYSTEMS TRANSFER SYSTEMS ANALYSIS & PRESENTATION STRATEGIC DATABASES OPERATIONAL TRANSACTION DATA

CATEGORIES OF INFORMATION PROCESSING RAW DATA CAPTURED/RECEIVED INSPECTED FOR QUALITY DATA USED IN AUTHORIZED INFORMATION PRODUCT DATA RETRIEVED WHEN NEEDED OBSOLETE DATA REPLACED SECURE & UNCONTAMINATED *

TYPES OF DATA STANDARDS IDENTIFIER: Unique value for each business entity NAMING: Unique name or label for each type of data DEFINITION: Unambiguous description for each type of data INTEGRITY RULE: Specify legitimate values for a data type USAGE RIGHTS: Security clearances for a data type *

ASSET MANAGEMENT FUNCTIONS PLAN SOURCE ACQUIRE & MAINTAIN DEFINE/DESCRIBE & INVENTORY ORGANIZE & MAKE ACCESSIBLE CONTROL QUALITY & INTEGRITY *

ASSET MANAGEMENT FUNCTIONS PROTECT & SECURE ACCOUNT FOR USE RECOVER/RESTORE & UPGRADE DETERMINE RETENTION & DISPOSAL TRAIN & CONSULT FOR EFFECTIVE USE *

STATISTICAL TOOLS OTHER TOO LS DATA WAREHOUSE NEW APPLICATIONS SYSTEMS LEGACY APPLICATIONS SYSTEMS OPERATIONAL STORE DATA WAREHOUS E DATA CAPTURING & PROCESSING DATA CLEANSING; SECURITY ISSUES SINGLE ENTERPRISE DATA REPOSITORY; ORGANIZED FOR ANALYSIS DATA ANALYSIS & PRESENTATION

DATA OWNERSHIP NEED TO PROTECT PERSONAL PRIVACY NEED TO PROTECT TRADE SECRETS REQUIREMENT TO ALLOW ONLY THOSE WITH ‘NEED TO KNOW’ ACCESS TO SENSITIVE MATERIAL *

DATA OWNERSHIP DESIRE TO PROMOTE INTERNAL COMPETITION, JUSTIFY USE OF SCARCE RESOURCES DESIRE TO SHOW COMMITMENT TO DATA OWNERSHIP DESIRE TO USE INFORMATION AS POWER FOR POLITICAL GAIN *

TRANSBORDER DATA FLOWS ELECTRONIC DATA MOVEMENT ACROSS NATIONAL BOUNDARIES CONTROLLED BY LEGISLATION: PREVENT ECONOMIC/CULTURAL IMPERIALISM PROTECT DOMESTIC INDUSTRY PROTECT INDIVIDUAL PRIVACY FOSTER INTERNATIONAL TRADE *

DATA ADMINISTRATION PROMOTE & CONTROL DATA SHARING ANALYZE IMPACT ON APPLICATIONS OF CHANGES IN DATA DEFINITIONS MAINTAIN DATA DICTIONARY: Consistent encyclopedia of data names, definitions, uses *

DATA ADMINISTRATION REDUCE REDUNDANT DATA & PROCESSING REDUCE SYSTEM MAINTENANCE COSTS, IMPROVE PRODUCTIVITY IMPROVE QUALITY & SECURITY OF DATA INSURE DATA INTEGRITY *

DATABASE ADMINISTRATION (DBA) TUNE DATABASE MANAGEMENT SYSTEMS SELECT & EVALUATE DATABASE TRAINING CONTROL PHYSICAL DATABASE DESIGN DESIGN METHODS TO RECOVER FROM DATABASE DAMAGE *

DATABASE ADMINISTRATION (DBA) SUPERVISE PLACEMENT OF DATABASES ON COMPUTERS & STORAGE DEVICES MANAGE INTERFACE OF DATABASES WITH TELECOMMUNICATIONS & OTHER TECHNOLOGY *

DATA STEWARD ESTABLISHES PROCEDURES GOVERNING DATA ELEMENTS ESTABLISHES ACCESS AUTHORIZATION PROCEDURES DETERMINES & EVALUATES MOST RELIABLE SOURCES OF DATA MAKES DATA DICTIONARY UNDERSTANDABLE TO USERS ENSURES THAT ONLY NEEDED VERSIONS OF EACH DATA ELEMENT EXIST *

DATA STEWARD ENSURES DATA USED IS MOST APPROPRIATE VERSION ASSIGNS RESPONSIBILITIES FOR DATA INTEGRITY RESOLVES CONFLICTS CONCERNING SHARABLE DATA CONSULTS WITH USERS ON USE OF ELECTRONIC DATA *

TOOLS FOR MANAGING DATA 1.DATA MODELING: –ENTERPRISE MODELING –VIEW INTEGRATION 2.DATABASE MANAGEMENT SYSTEMS: –RELATIONAL DBMS: Allows user to filter data with specific properties –STRUCTURED QUERY LANGUAGE 3.DATA DICTIONARY/DIRECTORY: A database about data, provides standard names, characteristics, uses *

INFRASTRUCTURE MANAGEMENT ISSUES 1.LOCATION 2.THE WORKSTATION 3.SUPPORTING OPERATING SYSTEMS 4.REDUNDANCY 5.SUPPORTING COMMUNICATIONS PROTOCOLS *

INFRASTRUCTURE MANAGEMENT ISSUES 6.BANDWIDTH 7.RESPONSE TIME ON NETWORK 8.SECURITY vs EASE OF ACCESS 9.BREADTH OF NETWORK ACCESS 10. ACCESS TO EXTERNAL DATA SERVICES *

APPLICATIONS PORTFOLIO MANAGEMENT ISSUES 1. ASSUMED USER: Skills? Interfaces? Needed software? 2.APPLICATION LOCATION: Centralized shareable resource, or stand-alone? 3.PROCESS-DRIVEN OR DATA-DRIVEN DESIGN 4.EVALUATION CRITERIA FOR NEW APPLICATIONS SYSTEMS *

ROLE OF USER-MANAGER 1. MAKE POSITION CLEAR ON CRITICAL INFRASTRUCTURAL MANAGEMENT ISSUES 2. TAKE ACTIVE ROLE IN DATA STEWARDSHIP 3. TAKE RESPONSIBILITY FOR FOLLOWING POLICIES 4. DEMAND QUALITY IS ASSET MANAGEMENT *
