  2. Theme Features of corporate information and retrieval system designing based on ODBMS ODB-Jupiter 4.0

  3. Generalized requirements for information and retrieval systems • Storage of large volume semi-structured information. • Separation of user rights to an information. • Fast information search applying various parameters. • Addition, deleting and changing of storied information. • Information output in convenient view for users.

  4. Purpose of ODBMS ODB-Jupiter ODB-Jupiter is specialized ODBMS for designing complex information storage and retrieval systems. Possible adaptation: • Automation of documents circulation. • Designing of question-answering systems. • Designing of digital libraries. • Designing of specialized corporate data storage and retrieval systems. • Designing of automatic control system for enterprises.

  5. Example of automatic information system base on ODBMSODB-Jupiter

  6. Server structure of ODBMSODB-Jupiter

  7. Data schemaof ODBMS ODB-Jupiter Object identifier format: • 32-bitidentifier of storage (time of storage creation) • String type name • 32-bit short object identifier Data schema features: • Data schema modification do not require rebuilding of stored objects of DB. • Administrator canmodify types and construct type hierarchy. • Any type includes a set of field determined by Administrator.

  8. Structure of ODBMSODB-Jupiter storage subsystem

  9. GUI of remote-control utility for ODBMS ODB-Jupiter 4.0 • Remote ODBMS control • Database includes several storages • For each type can be assigned individual storage

  10. ODBMS ODB-Jupiter 4.0 remote-control utilityAutomatic database backup

  11. Object security descriptor (OSD): Owner identifier, discretionary permission lists for each access type, discretionary prohibition lists for each access type, security labels «read» and «write». User account record: User identifier, List of group identifies what include this user, security labels «read» and «write», «read modification base» and «write modification base». User access control

  13. Discretionary Access Control. Access permission conditions • Level 1: Access permission byOBJECT TYPE SECURITY DESCRIPTOR: • User or at least one of his groupspresent in access permission listof OBJECT TYPE SECURITY DESCRIPTOR, • User and all his groups absent in access prohibit list of OBJECT TYPE SECURITY DESCRIPTOR, • Level 1: Access permission byOBJECT SECURITY DESCRIPTOR: • User is owner of the object, • User is not owner of the objectand: • User or at least one of his groupspresent in access permission listof OBJECT SECURITY DESCRIPTOR, • User and all his groups absent in access prohibit list of OBJECT SECURITY DESCRIPTOR.

  14. Security levels – item of the ordered set {free access, secret, top secretetc.} A set of categories – unordered set for information separation by categories. A set of areas – unordered set. For example, a region separation of users. Mandatory Access ControlSecurity labels

  18. Data storage and retrieval system ODB-Text 4.0 ODB-Textis a tool for development of collective document processing means and conducting corporate document storages. ODB-Textincludes following components: • ODBMS ODB-Jupiter 4.0; • Storage server andORB-server; • ODBMS remote control utility. • Data schema editor; • Client software ODB-Text; • Web-queries translator.

  19. Main features of the system • Collective work with documents. • Information search. • Information guarding. • Analytical data processing. • Remote working. • Integration with MS Office applications.

  20. BaseDocument MainDocument BaseDocument RubricDocument BaseDocument <New rubric type> <New document type> MainDocument <New parent type> RubricDocument <New document type> <New rubric type> Object data model • Document and rubrics has a type with original name and a set of requisites

  22. Object data model Object format in ODB-Text 4.0: • Object identifier • System requisites: • Name. • Data/time of creation. • Data/time of modification. • Security descriptor. • User’s requisites • Data schema editor allows to define any requisites.

  23. Data schemaData schema editor.

  24. Tree Rubricator Documents are organized by tree of rubrics: • Rubrics can have additional requisites. • Rubricator refreshing in real-time. • Filtering of documents and rubrics accordingly to given by user parameters. • Sorting of documents and rubrics by system and user requisites e.g. creation/modification date, name.

  25. Tree Rubricator

  26. Search facilities • Search of documents and rubrics. • Search objects by one or more types. • Using of type inheritance (query by parent type finds all objects of it type and all objects of children types). • Qualifying search by found objects. • Using of keywords and key phrases in query forming dialog. • Using of thematic dictionaries. • Textual data queries in the strict language form (coincidence, logical operations between words, ending masks etc) and the natural language form. • Storing of queries as object for using at future. • Search in a rubric and all subrubrics.

  27. Search facilities • Search results can be presented in the convenient form • Sorting results by one ore more requisites. • Quick results viewing by portion adjusted by an user. • Document and rubric requisites viewing.

  28. Document editor Includes: • Requisites editor. It allows to editing not only simple types such as date, time, string but also graphical and relationship types. • Accessibility for development and using of own requisites editors. • Viewing of document entry points and hypertext links. • Search of referred documents. • Using Microsoft Word editor as text editor.

  29. Document editor

  30. Integration withMicrosoft Word ODB-Text 4.0uses Microsoft Word for viewing and editing of a document text: • Natural language search by the text. • Keywords highlight and jumps. • Definition entry points of the text. • Markingof hypertext links to other ODB-Text documents. • Using all facilities of the document editor.

  31. Integration withMicrosoft Word

  32. Reports ODB-Text 4.0 forms reports: • Forming reports by search results, rubric content or other object list. • Reports can be saved in the text, rtf or html format. • Saved reports can be used by other software for special processing.

  33. Viewing an informationby Web-browser Possibility of Web-browser access makes an information system all-sufficient. It has following properties: • «Thin» clients. • Designing of informational Web-sites. • Web-browser works at all platforms. • Fully safety access (users can not change data in the database).

  34. Access Control Each object has a security descriptor. User with SCO change-access or owner of the object can change it at discretion.

  35. Specialized information storage and retrieval systems At the current on the base of ODB-Text 4.0 are developed following systems: • «Mass media message-flow processor»; • «Digital Library Development System».

  36. Mass media message-flow processor(MMF Review) Purpose: • Data fetching from various informational sources. • In-line processing. • Selection and preparation of information for users. • Preparation of reports at stored data.
