Source Database .SDB File Format


The Source Database (SDB) file format is Source's binary file format for storing time series data and associated metadata. SDB files support querying and searching, providing an efficient means of extracting individual time series from large data stores. The SDB supports the metadata listed in the table below. Some of the metadata fields are only relevant if the SDB file has been created from Results Manager based the results of a Source simulation.

Using the SDB File Format

The SDB file format can be created and imported, using Save As and Open options, in the same way as all other time series formats in Source - as found in Data Sources and Results Manager. However, the query filter whereby only certain fields are loaded, is only available through Results Manager
