ddn.odf.database

ODF database package model.

Provides preservation-first access to .odb database packages.

Database packages are complex ODF containers with embedded database files, forms, reports, queries, scripts, and connection metadata.

Database constructs

  • OdfDatabaseBody wraps the database body content
  • DatabaseConnection describes the connection type, URL, and settings
  • databaseBody() composing builder for constructing database bodies
  • Package contents preserved: forms, reports, queries, table definitions

Limitations:

  • No live database connectivity is provided
  • SQL queries and table data are preserved as raw XML
  • Form and report definitions are not parsed into typed structures

fn databaseBody dbConnection dbQuery dbTable emptyDatabaseBody

Types 4

structDatabaseConnection

Describes a database connection.

Fields
string driver

Methods
bool isEmpty() const @safe pure nothrowReturns `true` when no connection details are set.
structDatabaseTable

Describes a database table descriptor.

Fields
string name
string schemaName

structOdfDatabaseBody

Top-level model for ODF database package content.

Stores connection metadata, table/query descriptors, and preservation-first references to embedded resources.

Fields

Methods
bool isEmpty() const @safe pure nothrowReturns `true` when the body has no connection info.
