  8. 8. DISADVANTAGES OF E- RESOURCES  Technical barriers to use  need computers, network connection, software, etc  Infrastructural problems  bandwidth and telecommunications issues  unreliable electricity supplies, etc  Skills and training requirements  Costs can be high: technology and content  Variable quality of information
  9. 9. WHAT IS DATABASE?  A database is an organized collection of data. The data are typically organized to model relevant aspects of reality in a way that supports processes requiring this information.
