1. OBJECTIVE
TO STUDY THE RELEVANCE OF FIVE LAWS OF
LIBRARY SCIENCE IN MODERN DIGITAL ERA
TO INTRODUCE LIBRARY PROFESSIONALS
WITH SOME OF THE DATABASE
TECHNOLOGIES EFFICIENTLY USED IN
LIBRARY AND INFORMATION CENTRES

2. INTRODUCTION
INROADS BY COMPUTER AND OTHER
COMPONENTS OF ICT
INFORMATION SOCIETY, INFORMATION NEEDS : VARIED & ON THE RISE
LIBRARIES FROM STATIC TO LIVE ENTITIES, DOORSTEP OF THE USER, 24x7 FUNCTIONAL
WITHOUT BARRIERS OF BRICKS/WALLS and TIME
QUICK, EFFICINET, PERTINENT
POSSIBLE BECAUSE OF ICT and DATABASE TECHNOLOGIES

3. DATA, INFORMATION, DATABASE & DATABASE MANAGEMENT SYSTEM(DBMS)
• DATA : RAW FACTS WHICH CAN BE PROCESSED INTO ACCURATE & RELEVANT INFORMATION
• INFORMATION : DATA THAT HAS BEEN PROCESSED OR OPERATED ON BY COMPUTATION especially by a device like computer
• DATABASE : A COLLECTION OF DATA OR FILES SERVING AS A DATA RESOURCE FOR COMPUTER BASED INFORMATION SYSTEM
• DATABASE MANAGEMENT SYSTEM : A COLLECTION OF INTERRELATED DATA AND A SET OF PROGRAM TO ACCESS THE DATABASE
Data and information are closely related in the sense that information is processed, organised or summarised data.

4.FIVE LAWS AND DIGITAL ERA
• Law 1) Books are for use
• Law 2) Every reader his/her book
• Law 3) Every book its reader
• Law 4) Saves the time of the reader
• Law 5) A library is a growing organism
• 1. Online resources are available when and where needed,
• 2. Effective use of E resources prove that wherever the relevant material is available in the network that can be accessed.
• 3. WWW, Networking, Sharing and library Consortia ,
• 4. Multidimensional key word searching options,
• 5. No boundary and barrier of time/anytime anywhere

5.EMERGING DATABASE TECHNOLOGIES
• WHY ?• EFFICIENT MANAGEMENT OF INFORMATION
• FILTERATION
• EXTRACTION BY ACTING AS A REPOSITORY OF INFORMATION WITHIN ORGANISATION’S INFORMATION SYSTEM
• COLLECTION,PROCESSING,STORING,ANALYSIS : DISSEMINATION
7
5.1 INTERNET DATABASES
• INTERNET IS AN SELF REGULATED NETWORK OF COMPUTER NETWORKS CONNECTING MILLIONS OF INFORMATION CENTRES, BUSINESSES, INDIVIDUALS, GOVT. AGENCIES, EDUCATIONAL INSTITUTIONS AND OTHER ORGANISATIONS ALL OVER THE GLOBE.
• RESULTED IN THE EMERGENCE OF WWW WHICH ALLOWED THE USER TO HAVE DIRECT ACCESS TO DATABASES
• VAST WEB OF ELECTRONIC NETWORKS : INFORMATION SUPERHIGHWAY
……… contd.

INTERNET APPLICATIONS
9
• DISCOVERY : BROWSING,INF. RETREIVAL, DOWNLOADS
• COMMUNICATION : INF. TRANSFER, E MAIL, CHAT & DISCUSSION GROUPS
• COLLABORATION : B/W INDIVIDUALS, GROUPS, ORGANISATIONS (teleconferencing, resource sharing,
screen sharing..)
5.2 WEB DATABASES
• WWW or W3– the WEB is Not a synonym of internet but an APPLICATION OF INTERNET
• Internet acts as a transport mechanism
• MOST POWERFUL COLLABORATIVE NETWORKED INFORMATION DATABASE
• HANDLES ALL TYPES OF DIGITALINFORMATION : text, hypermedia, graphics, sounds
• STORES,RETREIVES,FORMATS and DISPLAYS INFORMATION
… contd. 10
WEB DATABASES
IT IS THE SYSTEM OF INTERLINKED HYPERTEXT MULTIMEDIA DOCUMENTS
WEB 1.0 : BASED ON FTP AND WAS A READ ONLY WEB
WEB 2.0 : READ & WRITE WEB WITH USER COMMUNICATION/ INTERACTION
WEB3.0 : SEMANTIC WEB, COLLABORATION OF CONTENTS. MORE LINKAGES & TAGGING
WEB 4.0 : FACILITATED USE OF RICH NEDIA
11
MOST WIDELY USED
WEB BROWSERS
INTERNET EXPLORER
NETSCAPE NAVIGATOR
MOZILA
5.3 DIGITAL LIBRARIES
• WHAT ?WHEN THE INFORMATION IS STORED ON
COMPUTERS AND WHICH IS ACCESSIBLE ONLY THROUGH AND ON COMPUTERS
INFORMATION IS STORED IN DIGITAL FORMATS AND RETRIEVED OVER NETWORKS
ARCHIVES AND REPOSITORIES ARE ORGANISED DIGITAL LIBRARIES FOR A LONG TERM PRESERVATION
…. contd.
12
DIGITAL LIBRARY
• NEED : SPACE CRUNCH
LIBRARY A GROWING ORGANISM
DIRECT AND MULTI LEVEL ACCESS
LONGEVITY
LOW COST COMPUTING TECHNOLOGIES
ELECTRONIC STORAGE CAPACITY
CONGREGATION OF RICH MEDIA
HIGH SPEED BROWSING
NETWORKING 13
5.4 MULTIMEDIA DATABASESIMAGES( pictures, photographs…)
VIDEO CLIPS(movies,news..) AUDIO CLIPS(speeches..)
TEXTUAL(books,jls.)
CONTENT BASED RETRIEVAL , LOCATING A PARTICULAR VIDEO OR AUDIO, IMAGE SEARCHING(MOST PREVELANT DATABASES)
APPLICATIONS : REPOSITORY APPLICATIONS, PRESENTATIONS, EDUCATION & TRAINING, INTERACTIVE KNOWLEDGE DISSEMINATION…….
14
DATA STORAGE
5.5 MOBILE DATABASES
i. WIRELESS TECHNOLOGY
ii. 3G & 4G MOBILE TECHNOLOGY
iii. SATTELITE PHONES FITTED WITH WITH LATEST SOFTWARES FACILITATES ACCESS FROM REMOTE LOCATIONS
iv. SMS/MMS, GPRS, INTERNET
v. Eg., Sybase’, SQL Anywhere, EVERYPLACE 7, IBM DB2, WINDOWS CE EDITION, Oracle 9i LIVE
15
5.6 SPATIAL AND GEOGRAPHICAL DATABASES
• DATA BASED ON SPATIAL LOCATIONS
• USEFUL FOR INDEXING & QUERYING DATA ON THE BASIS OF SPATIAL LOCATIONS
• HELPFUL IN DISASTER MANAGEMENT PINPOINTING EXACT LOCATION
• Eg., ROADMAPS, LANDUSE MAPS, TOPOGRAPHICAL MAPS
• IBM Spatial Extender, Oracle Spatial are COMMONLY USED DATABASES
16
5.7 ACADEMIC DATABASES AND DEARCH ENGINES
