Why BrightstarDB?

BrightstarDB is a unique and powerful data storage technology for the .NET platform. It combines flexibility, scalability and performance while allowing applications to be created using tools developers are familiar with.

An Associative Model

All databases adopt some fundamental world view about how data is stored. Relational databases use tables, and document stores use documents. BrightstarDB has adopted a very flexible, associative data model based on the W3C RDF data model.

BrightstarDB uses the powerful and simple RDF graph data model to represent all the different kinds of models that are to be stored. The model is based on a concept of a triple. Each triple is the assignment of a property to an identified resource. This simple structure can be used to describe and represent data of any shape. This flexibility means that evolving systems, or creating systems that merge data together is very simple.

Few existing NoSQL databases offer a data model that understands, and automatically manages relationships between data entities. Most NoSQL databases require the application developer to take care of updating ‘join’ documents, or adding redundant data into ‘document’ representations, or storing extra data in a key value store. This makes many NoSQL databases not particularly good at dealing with many real word data models, such as social networks, or any graph like data structure.

Schema-less Data Store

The associative model used in BrightstarDB means data can be inserted into a BrightstarDB database without the need to define a traditional database schema. This further enhances flexibility and supports solution evolution which is a critical feature of modern software solutions.

While the schema-less data store enables data of any shape to be imported and linked together, application developers often need to work with a specific shape of data. BrightstarDB is unique in allowing application developers to map multiple .NET typed domain models over any BrightstarDB data store.

A Semantic Data Model

While many NoSQL databases are schema-less, few are inherently able to automatically merge together information about the same logical entity. BrightstarDB implements the W3C RDF data model. This is a directed graph data model that supports the merging of data from different sources without requiring any application intervention. All entities are identified by a URI. This means that all properties assigned to that identifier can be seen to constitute a partial representation of that thing.

This unique property makes BrightstarDB ideal for building enterprise information integration solutions where there is a fundamental need to bring together data about a single entity from many different systems.

Automatic Data caching

Query results, and entity representations are cached to further improve performance for query intensive applications. Normally, data caching is done by applications but BrightstarDB provides this feature as a core capability.

Full Historical Capabilities

BrightstarDB uses a form of data storage that preserves full historical data at every transaction point. This allows applications to perform queries at any previous point in time, it ensures fully audit-able data and allows data stores to be returned to any previous state or snapshots taken at any point in time. This approach does increase the amount of disk space used, but BrightstarDB provides a feature to consolidate down to just the currently required data.

Developer Friendly Toolset

Most developers on .NET are accustomed to using objects and LINQ for building their applications. Database technologies that require a fundamental move away from this impose a large burden upon the developer. BrightstarDB provides a complete typed domain model interface to work with the data in the store. It adopts a unique position where the object model is an operational view onto the data. This means that many different object models can overlay the same semantic data model.

Native .NET Semantic Web Database

If you are working on .NET and want the power and flexibility of a semantic web data store. Then BrightstarDB is a great place to start. With support for the SPARQL query language and also the NTriples data format building semantic web based applications is simple and fun with BrightstarDB.

RDF is great for powering Object Oriented solutions

Objects are composed of properties, each property is either a literal value or a reference to another object. This creates a graph or related things with properties. ORM systems require that tables are organised in specific ways to facilitate storing object state. Changes to either the object model or the relational schema often require a reciprocal change. RDF on the other hand can ideally be used to store both literal properties and object relationships and if the object model needs to change then new property value can be added as there is no fixed schema. Similarly, if additional RDF data is added to the store the object model can either ignore or make use of this data. In this way the object model is an operational, read/write, view of the RDF data.
