Hitachi Creates Embedded Database for Devices

Continuing its commitment to innovating ways that let people search the way they think on converged and mobile devices, the Embedded Business Group (EBG) of Hitachi America, Ltd., a subsidiary of Hitachi, Ltd. (NYSE: HIT), released Entier 2.0. This new release, which adds to Entier’s already unique and powerful spatial search capabilities, is the first embedded relational database management system (RDBMS) to give developers of applications for converged and mobile devices the ability to incorporate the kind of high speed, advanced data management and sophisticated search capabilities that so far have been available only via massive computing environments such as online search engines.

Entier 2.0 builds off Hitachi’s original Entier, a small footprint RDBMS that allows mobile device application developers to easily and efficiently include sophisticated search functionality and reduce the amount of database access statements that need to be written by as much as 30-fold. Entier 2.0 adds two major new features – complex text search and alias search. Together, these features put the same search speed, power and accuracy end users have come to expect when using a search engine on their home computer into mobile devices such as GPS, PDAs and MP3 players.

“Music files, photos, video and all sorts of content are converging on many different devices, and developers of mobile applications need a way to distinguish their offerings when it comes to managing and finding content,” said Hiroshi Nakamura, vice president and general manager, Hitachi’s Embedded Business Group. “Entier 2.0 capitalizes on the advances in our original product, and takes search technology for mobile devices to the next level allowing end users to search the way they think on any converged or mobile device.”

Complex text search allows users to efficiently search for combinations of key words, using the common connectors “and,” “or” and “except” to include or exclude any number of keywords. For example, users no longer have to scroll or search through music by a specific artist or genre or timeframe looking for a song they want to hear and can’t exactly remember who sang it or what it was called. With Entier, users simply list some key words and instantly get a list of all songs on their device containing these words in any order or combination. Using alias search, users can not only search for a specific term, for example “U2,” but also words that describe that term – in this case, “Bono,” “The Edge,” “Adam Clayton,” “Larry Mullen,” “Irish rock,” “The Joshua Tree,” “Vertigo” and so on. Also new in Entier 2.0 are features including “Timeout,” and “Cancel” which give developers flexibility in programming their device.

“The amount of content that will be available for use on converged auto, mobile and home entertainment devices is growing at an unprecedented rate,” said Dr. Shiv Bakhshi, director of Mobile Technology and Trends/Devices at IDC. “Any methodology that helps users easily and efficiently search and retrieve the information they seek – whether a photo, a song or a location – is likely to find itself welcome in the emerging marketplace for mobile data.”

The new features in Entier 2.0 lay on top of the core search technologies that were announced with the original Entier in September 2006 – conceptual search that searches a variety of quantitative tags defined by content providers or the consumer, allowing users to find content that is similar to something else; and incremental text search, which progressively executes the search, narrowing down the results with each key stroke.

“Finding an efficient and intuitive way to manage digital content is a new challenge for all developers,” said Rich Schmitt, CTO, Blue Peach, which has incorporated Entier into its Blue Peach Digital Media Server. “This is no easy task, and requires a sophisticated, powerful solution that addresses data availability, reliability and scalability. The new features in Entier allow Blue Peach to make it even easier for consumers to manage and enjoy their digital content whenever they want.”

Like its predecessor, Hitachi Entier 2.0 is designed for small footprint consumer, commercial and mobile devices that require a fast, powerful, standards-based database manager. It enables the rapid delivery of innovative services on any platform, allowing developers to focus on tangible end-user benefits rather than invisible infrastructure, and reducing the amount of required application code by a factor up to 30-fold.

The database achieves rapid delivery by utilizing unique tagging and indexing features that require significantly less code (for example, two statements in Entier, vs. approximately 250 statements with a competitive embedded database product, including both application code and SQL statements) to conduct an incremental text search of a word like “Chicago.” This enables data to be located more quickly at execution time and applications to be developed more rapidly, providing benefit to both developers and end users. Entier is the first to combine a flexible runtime RDBMS and reliable file system with application-optimized spatial and incremental text search technology. Built on a foundation of total data reliability, Entier incorporates decades of database development expertise and is backed by Hitachi’s worldwide enterprise-class support.
