Introduction Tamino XML Server is a high performance data management platform based on XML standards built by Software AG to :  Efficiently store XML documents natively, that is in their original format.  Expose information residing in various external XML or non-XML sources (legacy data) or applications to the outside world in XML format, and  To search effectively on the information Tamino has access to.

Why is Tamino based on XML? Over the past years, XML has become the most important technology for Web-enabled infrastructures. XML's world wide acceptance comes from two important roles it plays for the Internet: It’s "MOM" capabilities (Messaging Oriented Middleware) based on XML's inherent extensibility and robustness. XML's MOM features allow for easy adaptation to changing business needs and flexible exchange of information between diverse IT systems.

Why is Tamino based on XML (2)? XML's "POP" capabilities (Presentation Oriented Publishing) content is separated from presentation. Thus, XML is ideally suited for creating and maintaining information only once, yet presenting it dynamically in a multiplicity of output formats and on a variety of display devices. Tamino XML Server is the first commercial server providing these highly efficient native XML storage capabilities.

Why Use Native XML Storage? Storing XML data natively has an enormous advantage over relational database management systems (RDBMSs) because:  No extra data conversion is required.  The document structure is kept intact.  The table-based data model of the RDBMS does not suit the hierarchical and interconnected nature of XML objects.  A query against XML-RDBMS database would result in a lot of relational retrieval and join operations, requiring high processing power to overcome a considerable degradation of performance.

Why Use Native XML Storage (2)? Native XML storage is the essential method to avoid these performance limitations that are a crucial factor in the evolving mission-critical high-speed world of e-business

General Architecture

General Architecture (2) The Native XML Data Store plus XML-Engine (XML Parser+ Object Processor) The central and most powerful components in the Tamino XML Server architecture. They provide:  Highly efficient storage  Native XML data store  Querying and retrieval of XML documents  Tamino X-Query  W3C-conform XQuery  and full-text retrieval functionality X-Machine

General Architecture (3)

General Architecture (4) XML Parser XML objects to be stored by the X-Machine are described by their schema stored in Tamino's Data Map. The XML-Engine's internal XML parser checks syntactical correctness of the schemas and ensures that incoming XML objects are well-formed.

General Architecture (4) Object Processor The Object Processor is used when storing objects in the native-XML store. Support of external data sources is provided by the Tamino X- Node and X-Tension.

General Architecture (5) Query Interpreter The Query Interpreter consists of the Query Compiler and the Query Executor. It optimizes the query along the given schema for resolving requests and checks whether indexes are available to accelerate query execution. It interacts with the Object Composer to retrieve XML objects according to the schemas stored in the Data Map.

General Architecture (5) Object Composer Using the storage and retrieval rules defined in the Data Map, the Object Composer constructs the information objects and returns them as XML documents. The simplest case will be retrieving an object stored natively as XML. In more complex cases, communication with X-Node and X-Tension is required to compose an XML object from non-XML data sources.

General Architecture (7) Data Map The Data Map contains the information required for the following functions:  Validation against logical schema  Storage and indexing of XML objects within Tamino  Mapping of data to different data structures (for example, relational databases) to enable the integration of existing data  Executing user-defined application logic

General Architecture (8) Data Map

General Architecture (9) Data Map Tamino is very flexible in its handling of XML documents and supports the storage of both well-formed XML (without an explicit schema definition) and valid XML (adhering to a schema).

General Architecture (10) The X-Node The X-Node is Tamino's integration component with external data storage systems:

General Architecture (11) The X-Node The X-Node feature enables client communication from the Tamino X-Machine to external databases via ODBC  For Windows systems: ODBC is part of the operating system and there is no requirement to install any additional ODBC support for Tamino.  For UNIX systems: ODBC support in Tamino is provided by the third party product SequeLink from DataDirect Technologies SequeLink 5.1 ODBC Client

General Architecture (12) The X-Tension Tamino's X-Tension component allows calls to user-defined functions, so-called Server Extensions

General Architecture (13) The X-Tension Server extensions allow for access to various external applications and for writing custom functionality enabling Tamino XML Server in meeting application specific needs. Tamino X-Tension provides a built-in XML-enabled interface for access to legacy processes and data sources.

General Architecture (14) The Tamino Manager The Tamino Manager is Tamino's administration tool

General Architecture (14) The Tamino Manager It is implemented as a client-server application and is integrated into the System Management Hub it is Tamino XML Server's point of central administration Tamino Manager allows the Tamino administrator to manage the entire system over the Web:  Create database  Start/stop server  Back up  Restore  Load, etc. Tamino Manager allows for the installation of Tamino X-Tension server extensions for greater flexibility.

Tamino Product Components There are several runtime and development components for ease of use and for application development with Tamino Tamino Schema Editor The Tamino Schema Editor supports you in creating Tamino schemas. Making schema creation much faster and less error-prone. Schema constructs required by the XML Schema standard are added automatically to ensure that valid schemas are generated.

Tamino Product Components Tamino Interactive Interface The Tamino Interactive Interface is a basic browser-based interface to Tamino XML Server. It allows you :  define collections within a schema  load XML instances of a schema into a database  query a database with the emerging standard W3C query language XQuery and the Tamino query language X-Query  delete XML instances, schemas and collections from a database.

Tamino Product Components Tamino X-Plorer The Tamino X-Plorer conveniently displays the contents of Tamino XML Server databases in a navigation tree, thus allowing you to explore and manipulate its contents. With Tamino X-Plorer's features you can:  Explore a Tamino XML Server's database  Query a Tamino XML Server's database  Maintain the structure and contents of a Tamino XML Server  Display, create and edit objects in a Tamino XML Server  Invoke tools which support you in developing Tamino applications (such as Tamino X-Application Generator)  View externally maintained data such as security data, server extensions, or WebDAV enabled collections

Tamino Product Components Tamino WebDAV Server WebDAV (Web-based Distributed Authoring and Versioning) is a set of extensions to the HTTP protocol which allows users to collaboratively edit and manage files on remote web servers

Tamino Product Components Application Programming Interfaces  Tamino API for Dot NET  Tamino API for Java (DOM, SAX, JDOM…) Tamino API for Java (DOM, SAX, JDOM…)  HTTP Client API for ActiveX (Windows )  HTTP Client API  HTTP Client API for JScript (Windows only)

Tamino Product Components Tamino X-Application Tamino X-Application allows you to access data which is stored in a Tamino XML Server using a standard browser interface thus providing a framework for Tamino application development. Tamino X-Application connects Web pages to Tamino without programming. It provides JavaServer Pages (JSP) tags to embed database access into HTML pages. With the JSP tags, common functionality is available to query, browse and maintain documents stored in Tamino.

Tamino XML Schema A schema is necessary for a lot of Tamino's functionality because in many situations Tamino just needs to know where or how data are stored to perform its tasks in an optimal manner.

Tamino XML Schema A schema is defined to Tamino in order to:  Validate XML instances to be stored in Tamino with respect to structural and data type aspects.  Define document types ("doctypes") belonging to a given collection with their respective names, access options and whether they allow to store XML or non-XML documents.

Tamino XML Schema  Associate indexing with elements and attributes defined in the schema. These are especially important for performance and sorting issues.  Associate mapping information with elements and attributes which controls whether they are stored natively in Tamino or in an external data store (via X-Node), e.g. Adabas or any SQL database At query time, these elements and attributes are again retrieved from the external database.

Tamino XML Schema In Tamino, we define a schema by the following two-step procedure: 1.Specify the structural information of the schema (Schema name, Collection name, namespaces). This is done by using the logical part of the Tamino Schema Definition Language (TSD). 2. Specify physical storage information (for mapping and indexing) This is done by using the physical part of the Tamino Schema Definition Language.

Indexing and Storing XML Data In the case of indexed data you need to specify at least a tsd:index element with either :  A tsd:text element (for the creation of a full-text index) or  A tsd:standard element (for normal indexing) As child element according to the type of index that you require.

Indexing and Storing XML Data

External Mapping Any mapping of parts of XML documents to externally stored data (Adabas, an SQL database or using a Tamino Server Extension) is specified using the tsd:map element

External Mapping

Mapping to SQL Tables and Columns The Tamino schema provides constructs that allow you to store data in SQL tables and/or retrieve data from an SQL table. Tamino either supplies an internal SQL store, or you can connect to external SQL databases via the X-Node.

Mapping to SQL Tables and Columns The mapping is implemented using the tsd:subTreeSQL and the tsd:nodeSQL child elements of the tsd:map element. The typical case is that subtrees of documents within a doctype but also entire documents may be mapped to SQL.

SQL-Mapping Specific Elements and Attributes

Example of Mapping to SQL The SQL table for the patient's personal details looks as follows:

In the TSD4, this can be defined in the following way:

Example (DEMO) This is step by step example showing how to :  Set up a database (Tamino Manager)  Define XML Schema (Tamino Schema Editor)  Insert/Load XML Doc (Interactive Interface)  Query database (Tamino Interactive Interface or X-Plorer)
