REXX (Restructured Extended Executor) is a programming language developed by IBM in the late 1970s, designed to be a scripting language particularly suited for mainframe operating systems like OS/390 and VM/CMS. It is a human-oriented (rather than machine-oriented) language, designed to be both simple to use and highly accessible to a non-technical user base. This approachability, combined with its wide-ranging use in various forms of data processing, has made it an enduring presence in the IT sector.

Data analysis, meanwhile, is the process of inspecting, cleansing, transforming, and modeling data with the goal of obtaining beneficial information, informing conclusions, and supporting decision-making. It aids in interpreting raw data in a significant manner, providing concise insights about the data, which increases the speed and efficiency of the decision-making process.

Role of REXX in data analysis

Given its human-oriented nature and its application versatility, REXX has naturally found a home in the area of data analysis. It is frequently used in extract, transform, load (ETL) operations, where raw data are taken from a source, transformed into a more useful format, and then loaded into a data warehouse or similar data storage system.

Its inherent simplicity means that complex tasks can often be handled with comparatively simple scripts. This, in turn, makes it easier for data analysts and other non-programming professionals to engage with the data directly, without having to rely on middlemen to translate their needs into functional code.

Implementation of ChatGPT-4 in data analysis with REXX

More recently, there has been significant interest in the potential application of artificial intelligence (AI) technologies in the realm of data analysis. One of these AI technologies is GPT-4, the fourth iteration of the OpenAI generative pre-training transformer model. GPT-4 uses machine learning to write human-like text, and this can be used to interpret and present data analysis results in a concise, easily understandable format.

With ChatGPT-4, it is possible to perform detailed data analysis tasks using REXX and present these insights in a way that is easily understandable even to individuals who may not be adept with understanding typical data visualization and raw data. Instead of needing to interpret charts, tables, or coded language, the results of a ChatGPT-4 data analysis can be presented in plain English (or whatever language is most appropriate for the end-users).

Conclusion

REXX, due to its simple nature and high accessibility, has proven itself to be highly effective in data analysis tasks. Incorporating ChatGPT-4 can enable presenting complex data analysis in an easily understandable format. This convergence of old and new technologies can result in better data visibility and more informed decision making, drastically improving business efficiency.

Ultimately, the combination of REXX's flexibility and the AI-driven power of ChatGPT-4 offers a powerful data analysis tool with an invaluable trait: accessibility. Every decision-maker, regardless of their level of technical knowledge, can access and understand the insights provided by these analyses, which can only lead to better, more informed decisions across the board.
