Problem Definition

• Why research and develop XML Databases?

4
Problem Definition - Definitions

• What are XML Databases?
• Searching for XML and Database on Yahoo.com
  yields approximately 2,000,000 results.
• Definition 1 (XMLDB mailing list members)
• Stores XML documents.
• Storage of XML documents is its fundamental unit
  of storage.
• No requirements for underlying physical storage.
• Definition 2 (Bourret)
• Designed to store XML documents
• Support features like transactions, security,
  multi-user access, programmatic APIs, query
  languages, and so on.
• Their internal model is based on XML and not
  something else, such as the relational model.

5
Problem Definition - Definitions (continued)

• What is meant by Native XML Databases?
• Native Merriam- Websters definition
• a constituting the original substance or source
  b found in nature especially in an
  unadulterated form ltmining native silvergt
• A text-based native XML database is one that
  stores XML as text.
• A model-based native XML databases build an
  internal object model from the document and store
  this model.

6
Problem Definition - Definitions (continued)

• How do I define Native XML Databases?
• Like Bourret, but
• Native XML databases are databases designed
  especially to store XML documents.

7
Background

• Why are XML Databases important?
• What has been done and by whom?

8
Background - Importance of Native XML Databases

• Related product categories
• Middleware
• XML-Enabled Databases
• Native XML Databases
• XML Servers
• Content Management Systems
• XML Query Engines
• XML Data Binding
• Discontinued products

9
Background - Advantages of Native XML Databases

• Convenience of XML document order format
• No cross-reference tables except for indexes.
• No order of appearance logic.
• Suggests enhanced searchability.
• May be operating system/RDBMS independent.

Detailed Plan

• What are the deliverables and time frame for
  completion?

12
Detailed Plan - Research Vision Mission (690)

• A System design and demonstration project.
• Versus a technology comparison project.
• Derive at least one reasonable Native XML
  Database interface and system architecture.
• User Requirements
• Functional Requirements
• Design and Architecture

13
Detailed Plan - Definition of Success

• SE 690
• Create a feasible system and interface
  architecture as a native XML database.
• Interface requirements and design.
• System requirements and design.
• SE 696
• Partially develop a software solution proving the
  proposed architecture.
• Implementation.
• Comparison to current implementations.
