Most companies, that have some sort of facility that generates a large volume of timestamped data consisting of a tag name, time stamp and a value, will at some point have to decide how they will store this data. Reasons for this vary, but for most industries there are usually government regulations stating that this data must be kept for a specific period of time; whether that period is 5, 7, 10 years or more. Along with being able to store this data to comply with government requirements, Engineers and Management within a company will use the data to make decisions to do with the process or plant.
The need to store this large volume of data in an efficient manner so it takes up minimal space is one reason for looking at data historians. Another and more important reason is the ease and speed at which this data can be retrieved. A data historian is specially designed to store and report on timestamped data. That being said, there are many data historians on the market therefore comparisons must be done.
In an attempt to compare these data historians a company must look at each one using the same criteria. Criteria such as
These and other criteria are used to compare one historian with another; the result being is that a company selects a data historian. In the past year, Streamline Control Solutions has completed an assessment of 7 different data historians using the various criteria mentioned above.
