Embedded Database Entier (Hitachi Data Systems)
High performance, small footprint RDBMS with advanced search capabilities
Entier is a high performance, small footprint RDBMS with advanced search capabilities. It is designed to solve the data management needs of applications running in devices with a relatively slow CPU and constrained memory footprint. Entier offers standard relational data access plus the ability to efficiently search text and spatial data. Developers choose Entier to reduce time to market, reduce development costs, and to provide a reliable data framework for device-level applications.
Entier was designed with the limitations of small devices in mind. Configurable to as small as 300K, Entier is based on a reliable file system that guarantees data integrity, even after a power failure.
- Incremental Text Search
Only Entier offers incremental text search. With each letter entered, Entier returns the number of possible hits and the possible next letters. Developers can use this information to create a guided interaction that leads users to the entry they are looking for.
- Efficient 3-D Search
With GPS-enabled devices becoming more common, and with mobile phone location available using other technologies, developers of many device applications are faced with the problem of locating data in space. Entier offers highly efficient R-Tree
