Time series compression algorithms osisoft
WebI know in the beginning the concepts of exception and compression were clearly centered on only storing meaningful data to conserve data storage in a time when a 124 MB hard drive was considered ridiculously big. As memory got cheaper and cheaper the importance of exception and compression on the storage side became "old fashioned".
