    • Topics of Interest - Databases
      What
      Why
      What is a database?
      An organized collection of information (data) which is arranged in individual records.
      What are the primary uses of a databases?
      Data collection and Data searching.
      Used everywhere to manage individual items of importance
      Grocery stores
      Banks
      Phone companies
      School systems
      Hospitals

    • Topics of Interest - Databases
      High School Database
      How
      Student
      Any tools to design databases?
      Microsoft Access, Oracle,
      Knowledge/ Skills needed to design databases
      Understanding needs of users
      DB concepts
      Data Modeling
      Design guidelines
      Database programming language

    • Topics of Interest - Forms
      Forms
      Example
      Globally used for data collection
      All users(irrespective of their technical knowledge) are familiar
      Scenarios:
      Survey data collection
      Craigslist ad posting
      Gmail, yahoo, facebook account Sign Up
      5
    • Research Focus
      To make DATABASES more useful for those USERS
      who have no background in databases
      who still want to use databases for DATA COLLECTION.
      In this study, I explore how FORMs can be used to accomplish this.

    • User-Database Equation First Generation
      Examples:
      MS Access
      Patient
      Accomplishment: Users can collect data into databases on their own.
      Shortcoming: Users depend on the database expert to specify their data collection needs.

    • User-Database Equation Second Generation
      Examples:
      Google Forms
      FormAssembly
      Zohocreator
      Patient
      collect
      data
      Accomplishment: Users can design databases based on customized data collection needs without depending on the database experts.
      Shortcoming: Unfit for dynamic /critical environments (like healthcare) – where data collection needs keep evolving and changing.

    • User-Database Equation Third Generation (My Precise Topic)
      Patient
      How to merge a form to an existing database?
      ?
      VitalSigns
      design
      How to integrate new needs with
      existing ones such that the information represented in database in minimal.
      Clinician
      New User Designed Form
      Form to Database Mapping
      9
      New Needs
      Existing Database
      Evolved Database
      Why this is IMPORTANT? Solves healthcare issues:
      Dependence on experts
      Inconsistency between needs and databases
      Inflexibility of systems
      Why this is INTERESTING?
      It uses forms and databases.
    • Experiments (in healthcare domain)
      B
      Efficiency
      Existing Database
      Form to Database Mapping
      New User Designed Form
      C
      A
      Effectiveness: Is the evolved database of high quality w.r.t data collection needs of user ? Correctness, Completeness, Normalization, Minimalism.
      Can clinians use system to specify their data collection needs in terms of forms? (Usability Study)

    • Future
      This Research helps…
      Understand the Technical Details of Forms and Databases.
      Understand the issues in healthcare; Interaction with users to understand their problems and design real-world solutions for them.
      grow as a researcher
      After my graduation I plan to …
      work as a Researcher in a Laboratory (addressing the issues of healthcare and several other industries)
