Transcript

  • 1. STRUCTURED DATA WHAT IS STRUCTURED DATA? STRUCTURED DATA IS DATA THAT IS APPLIED TO A UNIVERSAL FORMAT MAKING IT EASILY RECOGNIZED, UNDERSTOOD AND DISPLAYED BY SEARCH ENGINES. • Representation: discrete (rows and column). • Storage/persistence: DBMS or File format (ex: VSAM ' Virtual Storage Access method ‘). • Metadata focus: syntax (ex. location and format). • Standards: SQL, ADO.NET, ODBC (Open Database Connectivity), RDMS support XML as another option.
  • 2. UNSTRUCTURED DATA • THE FOUNDATION OF TEXTUAL ANALYTICS IS THE ABILITY TO ACCESS AND ANALYZE UNSTRUCTURED DATA IN AN UNFETTERED MANNER • TO ACHIEVE THIS STATE, AN INFRASTRUCTURE SUITABLE FOR ANALYTICAL PROCESSING MUST BE CREATED. The heart of that environment is the unstructured database.
  • 3. UNSTRUCTURED DATA (CONT.) • REPRESENTATION: * BINARY LARGE OBJECTS: LESS-DEFINED BOUNDARIES, LESS EASY ADDRESSABLE. * SMALL DISCRETE OBJECTS: INFORMATION REPRESENTED FOR A VERY SPECIFIC PURPOSE. • STORAGE / PERSISTENCE: UNMANAGED. • METADATA FOCUS: SEMANTICS (DESCRIPTIVE AND OTHER MARKUP). • STANDARDS: OPEN XML, SMTP (SIMPLE MAIL TRANSFER PROTOCOL), SMS, CSV, INFORMATION AND CONTENT EXCHANGE.
  • 4. EXAMPLES OF STRUCTURED DATA - DATABASES - DATA WAREHOUSES - XML DATA - ENTERPRISE SYSTEMS (CRM, ERP, ETC.)
  • 5. EXAMPLES OF UNSTRUCTURED DATA - EXCEL SPREADSHEETS - WORD DOCUMENTS - EMAIL MESSAGES - VIDEO FILES - RSS FEEDS - AUDIO FILES
  • 6. SEMI-STRUCTURED DATA • IS A FORM OF STRUCTURED DATA THAT DOES NOT CONFORM WITH THE FORMAL STRUCTURE OF DATA MODELS ASSOCIATED WITH RELATIONAL DATABASES OR OTHER FORMS OF DATA TABLES. • ENTITIES BELONGING TO THE SAME CLASS MAY HAVE DIFFERENT ATTRIBUTES EVEN THOUGH THEY ARE GROUPED TOGETHER “THE ATTRIBUTE ORDER " IS NOT IMPORTANT.
  • 7. SEMI-STRUCTURED DATA (CONT.) • SEMI-STRUCTURED DATA IS INCREASINGLY OCCURRING SINCE THE ADVENT OF THE INTERNET WHERE FULL-TEXT DOCUMENTS • IN OBJECT-ORIENTED DATABASES, ONE OFTEN FINDS SEMI-STRUCTURED DATA.
  • 8. TYPES OF SEMI-STRUCTURED DATA • XM • EMAIL • OME (OBJECT EXCHANGE MODEL) • EDI (ELECTRONIC DATA INTERCHANGE)
