  1. 1. MAKINGDatabasesUsable Forusers<br />Ritu Khare . July 8 2010. <br />1<br />
  2. 2. Order of Presentation<br />Topics of Interest<br />Databases<br />Forms<br />Making Databases Usable<br />First Generation Applications<br />Second Generation Applications<br />Third Generation – my topic<br />Experiments<br />Future<br />2<br />
  3. 3. Topics of Interest - Databases <br />What <br />Why<br />What is a database? <br />An organized collection of information (data) which is arranged in individual records.<br />What are the primary uses of a databases?<br />Data collection and Data searching. <br />Used everywhere to manage individual items of importance<br />Grocery stores<br />Banks<br />Phone companies <br />School systems <br />Hospitals<br />3<br />
  4. 4. Topics of Interest - Databases <br />High School Database<br />How<br />Student<br />Any tools to design databases?<br />Microsoft Access, Oracle, <br />Knowledge/ Skills needed to design databases<br />Understanding needs of users<br />DB concepts<br />Data Modeling<br />Design guidelines<br />Database programming language<br />Course<br />StudentCourse<br />4<br />
  5. 5. Topics of Interest - Forms<br />Forms<br />Example<br />Globally used for data collection<br />All users(irrespective of their technical knowledge) are familiar<br />Scenarios:<br />Survey data collection<br />Craigslist ad posting<br />Gmail, yahoo, facebook account Sign Up<br />5<br />
  6. 6. Research Focus<br />To make DATABASES more useful for those USERS <br />who have no background in databases <br />who still want to use databases for DATA COLLECTION. <br />In this study, I explore how FORMs can be used to accomplish this. <br />6<br />
  7. 7. User-Database Equation First Generation<br />Examples:<br />MS Access<br />Patient<br />Accomplishment: Users can collect data into databases on their own. <br />Shortcoming: Users depend on the database expert to specify their data collection needs. <br />collect <br />data<br />Expert <br />Designed DB<br />design<br />design<br />Expert Designed Form (Front End)<br />Clinician<br />Data collection needs<br />DB Expert<br />7<br />
  8. 8. User-Database Equation Second Generation<br />Examples:<br />Google Forms<br />FormAssembly<br />Zohocreator<br />Patient<br />collect <br />data<br />Accomplishment: Users can design databases based on customized data collection needs without depending on the database experts. <br />Shortcoming: Unfit for dynamic /critical environments (like healthcare) – where data collection needs keep evolving and changing. <br />design<br />VitalSigns<br />Clinician<br />User-Designed Form (Front End)<br />User Designed DB<br />8<br />
  9. 9. User-Database Equation Third Generation (My Precise Topic)<br />Patient<br />How to merge a form to an existing database?<br />?<br />VitalSigns<br />design<br />How to integrate new needs with <br />existing ones such that the information represented in database in minimal.<br />Clinician<br />New User Designed Form<br />Form to Database Mapping<br />9<br />New Needs<br />Existing Database<br />Evolved Database<br />Why this is IMPORTANT? Solves healthcare issues:<br />Dependence on experts<br />Inconsistency between needs and databases<br />Inflexibility of systems<br />Why this is INTERESTING?<br />It uses forms and databases.<br />
  10. 10. Experiments (in healthcare domain)<br />B<br />Efficiency<br />Existing Database<br />Form to Database Mapping<br />New User Designed Form<br />C<br />A<br />Effectiveness: Is the evolved database of high quality w.r.t data collection needs of user ? Correctness, Completeness, Normalization, Minimalism.<br />Can clinians use system to specify their data collection needs in terms of forms? (Usability Study)<br />10<br />
  11. 11. Future<br />This Research helps…<br />Understand the Technical Details of Forms and Databases. <br />Understand the issues in healthcare; Interaction with users to understand their problems and design real-world solutions for them. <br />grow as a researcher<br />After my graduation I plan to …<br />work as a Researcher in a Laboratory (addressing the issues of healthcare and several other industries)<br />11<br />
