Handling of Large Binary Objects (LBO)

The digitization of continuous analogue signals produces digital streams of considerable duration and a significant number of large size binary files in the framework of a projects database. As the capacities of storage devices recently developed from medium size in the GigaByte range into mid TeraByte volumes, more and more attention has to be focussed on the management and structuring of large binary objects. Data access, search and retrieval, as well as consistent update strategies have to be organised along new challenging circumstances. Although recent developments in computer technology have accelerated the re-organization and migration of large data bases considerably, new and elaborated concepts of data management still face urgent demands.

From practical experience, essence needs metadata – and ones metadata is the others essence – however both have to be coordinated thoroughly. New methods of automatic created content related annotations of signals have been introduced in the last years to meet the new requirements of handling excessive large data volumes and their content.

Disk and File Volume Management

The table below shows the maximum record length in 24h-days to be stored on a 1 TByte hard disk in dependence of the sampling frequency (first row in kHz, wordlength 16 bit) and the number of channels (first column). The usual file size under Windows is 2 GByte, STx accepts file sizes up to 8 GByte.  Values  with (*) have not been tested up to now. For multi-channel recording a STx macro language script is available, contact the STx software team.
