ORACLE DATA SHEET ORACLE BERKELEY DB XML OVERVIEW Oracle Berkeley DB XML is a high-performance embeddable database engine for developers of mission critical XML applications. It runs directly in the application that uses it, so no separate server is required, and no human administration is needed. Berkeley DB • Embeddable XML database engine • Support for XQuery and XPath XML manages XML documents using XQuery and offers advanced data management services, including concurrent access, transactions and replication for high availability and fault tolerance. • Flexible indexing for optimizing search and retrieval • Flexible storage control – nodes or whole documents Embedded XML Data Management Oracle Berkeley DB XML offers software developers a fast, reliable and scalable • Partial document updates XQuery engine with sophisticated XML content storage in a packaged that can be • Schema support, including embedded inside an application. Berkeley DB XML is equally at home managing validation • Runs in process with the application • Concurrent access by multiple content at nodes within a Service-Oriented Architecture (SOA), storing data for a PHP Web application, and managing massive volume of genomic or geographic data requiring complex query analysis. threads or processes • Full ACID transactions XML is a widely used format for publishing and exchanging data among systems, in • Replication for high availability particular for Web Services and SOAs. As the volume of XML data increases, it has • Zero administration become increasingly critical that applications and SOA components be able to store, manage, and retrieve XML without the overhead of translating it into other formats. Berkeley DB XML allows developers to do just that quickly and easily within their applications, without resorting to an external storage system or expensive and time consuming setup and administration. Berkeley DB XML runs directly inside the application that uses it, so no separate database server is required. Berkeley DB XML stores XML documents in XML, and supports the XQuery standard for querying data. Enterprise-class Storage Because it is built on top of the proven and mature Oracle Berkeley DB storage engine, Berkeley DB XML inherits all the features, performance, reliability and scalability that Berkeley DB delivers. Berkeley DB XML can store terabytes of data in a single document repository. The database can survive power outages, software errors and hardware failures without losing data. It supports simultaneous access to the document store by large numbers of users. Designed for Networked Applications One of the most common uses of Berkeley DB XML is for storing documents in network-based applications. Content management systems, which store and publish XML documents over the Internet, may use Berkeley DB XML as their repository. High-performance networking devices like switches, routers and gateways use 1

ORACLE DATA SHEET BERKELEY DB XML – Berkeley DB XML to manage control information and the data that flows through EMBEDDED XML them. BERKELEY DB XML DELIVERS ENTERPRISEGRADE STORAGE SERVICES FOR XMLBASED APPLICATIONS. A common requirement of these systems is a fast, local, persistent store for XML data. Low latency and high throughput are crucial. Berkeley DB XML eliminates runtime overhead by operating within the embedding application thereby providing direct memory access, rather than client/server based access, to XML content. This eliminates the round trip to and from the server during runtime,...
