Few things you need to know about COBOL-arrays. Arrays have multiple benefits. While reading an i/p file, in batch process, the only way you can store data internally is in arrays. So, the data can be used for processing within the program.
COBOL Arrays
Important points are:
Point1:
01 Array-example
02 Table-1 occurs n times
03 Field-1 pic x(2)
03 Field-2 pic x(3)
Here the ‘n’ times is any value from ‘1’ to ‘32767’
Point 2:
We know arrays are fixed length, variable length. While working with DB2, the array must handle BLOB and CLOB (Binary large object and Char Large object)

Modern applications often allow users to upload files—documents, invoices, images, or datasets. But a production-grade upload pipeline must be secure, scalable, and well-organized. In this article, we will build a complete end-to-end architecture where: We will implement this using Amazon API Gateway, AWS Lambda, PostgreSQL, and Amazon S3. This architecture is widely used in cloud-native…
AI agents are revolutionizing data engineering by automating tasks such as monitoring pipelines, generating SQL queries, and ensuring data quality. They enhance productivity, speed up troubleshooting, and improve data accessibility for users. While offering significant advantages, AI agents also face challenges in security, accuracy, and integration with existing systems.
Artificial Intelligence tools are on the rise, from writing assistants to coding helpers and automation platforms. However, many professionals struggle to compare these tools effectively. This is where the AI Stack becomes important. Modern AI tools like ChatGPT, NotebookLM, and Antigravity serve different purposes, and understanding their roles helps in: Layer 1: Conversational AI (Thinking…
