Design, validate, and structure XML documents using standard modeling approaches
This course enables participants to acquire the skills needed to master the syntax of the XML language, the W3C standard, and the associated modeling rules. Exercises and case studies will guide the learning of creating and structuring XML documents, as well as related concepts such as XSL schemas and namespaces.

Prerequisites
Basic knowledge of XML technologies and data modeling
What You'll Walk Away With
- ✓ Understand XML document structure, well-formedness, and validation rules
- ✓ Design XML data models using DTD, XML Schema, and related schema languages
- ✓ Manage namespaces to combine and organize multiple XML vocabularies
- ✓ Define simple and complex types, constraints, and uniqueness rules in XML Schema
- ✓ Apply modeling best practices to create extensible and reusable schemas
Training content
1 Review of XML and associated technologies:
- Structure of an XML document, element tree.
- Components of an XML document : declarations, processor instructions, comments, entities, elements, attributes.
- Well-formed and valid document.
- Rules for well-formed documents, logical structure of an XML document.
- Structured and semi-structured data.
- Different types of XML parsers and their roles.
- The galaxy of XML technologies.
2 XML and document composition:
- Objectives of structuring languages: DTD, XML Schema, Schematron, and Relax NG.
- Why a schema is necessary.
- How to use schemas.
- Main characteristics and parts of schemas.
- How schemas work.
- Different modeling languages.
- EBNF syntax for DTD (Data Type Definition).
- Document validation.
- Different types of entities and their use.
- Multiple root DTD.
- Extensibility and reuse of model components.
- Language limitations.
3 Namespaces:
- Description of namespaces
- Use of namespaces
- Namespaces and the combination of multiple vocabularies
- Combination of languages: XHTML, Xforms, and SVG
- Mistakes to avoid
- Study of the scope of a namespace
- Definition of a URI.
4 XML Schema language:
- Language syntax.
- Definition of a vocabulary (elements, attributes, etc.) and grammar.
- Document validation.
- Testing element and attribute values.
- Study of simple and complex data types.

5 XML modeling techniques:
- Design patterns.
- Unique schemas applicable to different types of documents.
- Reusable generic models (list, grid, etc.).
- Documents using multiple schemas.
- Creation of extensible schemas and control of extensibility.
6 XML and object design:
- Review of object-oriented concepts.
- Object concepts of the XML Schema language.
- Types, class, derivation, polymorphism.
- UML/XML representation.
- Schema inclusion.
- Schema import.
- Schema redefinition.
7 Best modeling practices:
- Composition and inheritance.
- Construction types: “Russian dolls”, “Salami slices”, and “Venetian blinds”.
- Adaptation schemas.
- Definition of containers and elements.
- Design pattern catalogs.
- Localization or exposure of namespaces.
- Homogeneous and heterogeneous documents.
- Global or local definition of components.
- Working with elements or types.
