POSLog: One data container to rule them all .. well at least for Retail.

By Justin Hewitt

The topic for today is "big retail" and how an industry standard data container (the ARTS POSLog) can tackle common integration issues with different retail systems and abstract the "Point of Sale" data collection layer from the backend processing layers.

Usually we blog about using data once you have aggregated it; but today lets go back a step and talk about the data collection/transmission management and setting up the plumbing that will ultimately make data aggregation much easier, which in turn will makes your retail BI data collection easier and faster to gain insights from.

POSLog (the data container) is an industry open standard retail schema developed by ARTS, a subgroup of the National Retailer Federation.  It has been around a while and is quite mature as a standard; but still not too many people have heard of it.

The primary goal of an industry defined schema like the ARTS POSLog, is to reduce costs through standards. That is, by setting a standard for data transmission and interchange that all POS vendors adhere too, you ensure consistency across platforms and this gives retailers more flexibility with their selection of software and hardware for the ‘point of sale’.

The POSLog is a standard that works internationally and reveals the similarities between POS practices country to country.  Japanese, American, Australia or Icelandic retailers (as a sample set) can all map their retail data into the POSLog schema. The POSLog can be used as an asynchronous data transmission container or synchronous request/reply type data exchanges where both directions are POSLog.

Retail Data Collection.

Just as a background, your typical retail data collection from a customer interaction, will document:

• POS Channel.
• Sales Items (SKU’s/Services sold)
• Methods of payment, e.g. cash, EFT, cheque, account, layby, prepaid, voucher
• Physical location of outlet/POS e.g. site ID, lat/long, department, floor region
• Operator identification
• Supplemental data e.g.  Item reference, customer personals, government requirements
• Control features, e.g.,  receipt number, date and time, etc.
• BLOB data e.g. images, encrypted data
• Money movements e.g cash out to HQ
• Operator logins/logouts & security changes
• Errors, surpluses, deficits etc.
  

Frequently Asked Questions About POSLog in Retail Systems

What is POSLog in retail systems?

POSLog is an industry-standard data format developed by ARTS to standardize how point-of-sale (POS) data is captured, stored, and transmitted. It helps retailers unify transaction data across different systems, making integration and analytics more efficient.

What is the purpose of POSLog in retail data integration?

The purpose of POSLog is to create a consistent data structure for retail transactions, reducing complexity when integrating multiple POS systems. It ensures data consistency across platforms, enabling easier reporting, analytics, and system interoperability.

How does POSLog improve retail data management?

POSLog improves retail data management by standardizing transaction data formats, which simplifies data collection, reduces errors, and enables faster data processing for analytics and reporting systems.

What types of data are included in POSLog?

POSLog includes detailed retail transaction data such as sales items (SKUs), payment methods, store location, operator details, timestamps, receipts, customer data, and other transactional or operational information.

How does POSLog help in integrating multiple POS systems?

POSLog acts as a common data layer that allows different POS systems to communicate using the same format. This reduces the need for custom integrations and simplifies data exchange between systems.

What is ARTS POSLog and who developed it?

ARTS POSLog is a retail data standard developed by the Association for Retail Technology Standards (ARTS), part of the National Retail Federation. It provides a unified schema for handling POS transaction data globally.

What are the benefits of using POSLog for retailers?

POSLog offers benefits such as reduced integration costs, improved data consistency, faster data processing, and greater flexibility in choosing POS software and hardware across different vendors.

Can POSLog be used for real-time data processing?

Yes, POSLog can support both real-time (synchronous) and delayed (asynchronous) data transmission, allowing retailers to process transactions instantly or in batches depending on system requirements.

How does POSLog support retail analytics and business intelligence?

By standardizing transaction data, POSLog makes it easier to aggregate and analyze data across multiple systems. This improves reporting accuracy and enables faster insights for business intelligence and decision-making.

Why is data standardization important in retail POS systems?

Data standardization ensures consistency across different systems, reduces integration complexity, and enables seamless data exchange. This is essential for accurate reporting, analytics, and scalable retail operations.
