Provides the database schema encapsulation.
Package SpecificationThe classes in this package provide a database independent abstraction of database access for a variety of catalogs.
To provide an alternative implementation for an existing catalog, you need to:
Currently, several concrete catalogs are implemented in Chimera:

| Advanced.java | Interface | This common schema interface defines advanced search interfaces for VDC. |
| Annotation.java | Interface | This common schema interface defines the schemas in which the
abstraction layers access the metadata associated with VDC elements.
This layer is independent of the implementing database, and does so
by going via the database driver class API.

| AnnotationSchema.java | Class | This class provides basic functionalities to interact with the
backend database, such as insertion, deletion, and search.
While the main database layout for storing definitions is derived
from the "chunk" schema with minor improvements, the database
layout of the annotations is shown in the following figure:
The central five elements that can receive annotations, all depend on the same sequence generator for their primary key. |
| Catalog.java | Interface | This interface groups different but related catalog subinterfaces.
The interface will require implementing classes to provide a constructor that takes one String as only argument. |
| ChunkSchema.java | Class | This class provides basic functionalities to interact with the
backend database, such as insertion, deletion, and search of
entities in the VDC.
author: Jens-S. |
| DatabaseSchema.java | Class | This common schema interface defines the schemas in which the abstraction layers access any given database. |
| InMemorySchema.java | Class | This is a class that falls back not on a real database backend, but rather on an existing Definitions data structure in main memory. |
| InvocationSchema.java | Class | This class provides basic functionalities to interact with the
backend database for invocation records, such as insertion, deletion,
and search.

| MyCallbackHandler.java | Class | This class adds a given Definition from the parser's callback into the fresh in-memory storage. |
| NXDInvSchema.java | Class | This class provides basic functionalities to interact with the
backend database for invocation records, such as insertion, deletion,
and search.
author: Jens-S. |
| NXDSchema.java | Class | This class provides basic functionalities to interact with the
backend database, such as insertion, deletion, and search of
entities in the VDC.

| PTC.java | Interface | This interface defines a common base for all database schemas that supports the handling of the provenance tracking catalog. |
| SingleFileSchema.java | Class | This is a class that falls back not on a real database backend, but
rather on an existing Definitions data structure that are read from
file during construction (or rather, during open), and pushed back
into file at destruction (or rather, during close). While schemas in general should fall back onto drivers to perform actions, it is rather difficult to create a JDBC interface to file operations. |
| VDC.java | Interface | This common schema interface defines the schemas in which the abstraction layers access the VDC. |
| WF.java | Interface | This common schema interface defines the schemas in which the abstraction layers access the WF database. |
| WorkflowSchema.java | Class | This class provides basic functionalities to interact with the backend database for workflow records. |
| XDC.java | Interface | This common schema interface defines advanced search interfaces for VDC. |
