Namespaces

actionETL

This is the main actionETL namespace.

actionETL.Adb

The Adb infrastructure (in actionETL.Adb and its child namespaces) is used in ETL applications for accessing databases via SQL, both on-premises, and in the cloud. This includes both relational SQL databases, NoSQL databases, and many other querying systems, accessible via dedicated providers or via the Adb ODBC Provider.

Adb consists of wrappers around the standard .NET database routines residing in System.Data and similar namespaces, adding ETL functionality such as:

  • Get tables and columns available
  • Support for provider-specific data types, which are very useful for avoiding conversion issues
  • Enhanced automated mapping between .NET CLR types and database types
  • Encapsulating database connections, to support both short-term connections that are opened and closed as needed inside a worker, and connections that are kept open until explicitly closed by the library user, e.g. for using a single transaction or temporary table across multiple workers
  • Execute predefined table commands, e.g. delete all rows, truncate, drop, exists
  • Provide additional information about the database, which assists with writing provider-independent code, so that a worker (such as AdbInsertTarget) can support all Adb database providers.
    • Note: This aspect is mainly used when developing your own custom Adb workers

Contains the adapter and extensions for the NLog library, which is the default implementation for actionETL.Logging.

Also see Logging.

Thread Safety

All public static members (methods, properties, fields, and events) in actionETL are thread-safe, while all instance members are not guaranteed to be thread-safe, unless the member documentation states otherwise.

Note that many instance members are in fact thread-safe. Some members also have further constraints, such as worker result members only being available after the worker has completed. See the documentation for details.
