Data Historian Comparison

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

  1. “Core Historian” – what are the various attributes associated with the core product that makes it a functional historian.“Calculation Platforms” – Once data is stored, is there the ability to perform calculations on the data.
  2. “Asset Hierarchy Integration” – Is there a facility to build a hierarchy of the facilities and equipment that can be used for calculations and reporting.
  3. “Programing Interfaces” – Are there interfaces available that will allow a client to code to pass data from the historian to other software products.
  4. “Client Tools” – Are there client tools available for reporting purposes.  For example, is there an Add-in for Microsoft Excel.
  5. “Vendor Technical Support” – Does technical support come with the historian? Is it 24/7 or dependent on a package purchased.
  6. “Training/Local Expertise” – What form of training is available and is there local expertise with knowledge of the historian.
  7. “Administration/System Complexity” – How complex is the system and how easy it is for the client to perform Administration functions with the historian.

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.  Give Streamline a call if you might be interested in seeing the results of this assessment.
