SIERRA: A Spatial Data System for Neuronal Data

Neuroinformatics requires the manipulation and querying of data in a spatial, visual, and relational milieu. SIERRA is a system for storing and querying neuronal data within a relational data framework, and hybridizes proven technologies (RDBMS, octrees) to meet stringent real-time visualization requirements in a simple yet elegant way. 1 Introduction We present SIERRA 1 , a spatial database system in which normalized spatial representations of objects can be efficiently stored, and the spatial relations of these objects graphically displayed, using a hybrid of octrees, RDBMS and 3-D visualization technology. SIERRA was developed in support of NEUROSYS 2 , a tool used to explore the functional relationships and connectivity patterns between small and large ensembles of neurons. In this paper, we will discuss how data are stored and queried in SIERRA, the role of SIERRA as a component of NEUROSYS, and future directions for research. The first test-version of SIERRA was implemented ..
