What is Adabas?

Adabas (adaptable database system) is a database management system that helps users handle large volumes of almost any type of data. Some of Adabas’ benefits include:

  • High availability: It has been designed to operate continuously for extended periods of time, which can make it an excellent choice for running mission-critical applications.

  • Storage space optimization: It optimizes storage space and ensures efficient system performance by storing data in a compressed form.

  • Fault tolerance: It can quickly recover after a system malfunction. It also features backup components that automatically replace failed ones to avoid system disruptions. 

Adabas also allows users to choose the data model that best suits their needs. Because it supports relational, entity, hierarchical, geographical, and text data models, Adabas combines elements from both relational and non-relational databases. Like relational databases, Adabas can store data in tables and link files by a common field. And, like non-relational databases, Adabas can also store multiple data relationships in the same table. This approach allows for greater flexibility and makes it easier to manage and retrieve data.Footnote 1

How does Adabas work?

Adabas uses a programming language called Natural to create, modify, read, and protect data. Natural was developed by Software AG as a more simple and user-friendly alternative to legacy mainframe languages such as COBOL. It’s a fourth-generation programming language, which means its syntax is closer to human language than numbers-based machine language.Footnote 2

While Adabas and Natural are often viewed as legacy technologies, there are many businesses whose IT operations will depend on them for years to come. To ensure its platform remains relevant and useful for clients, Software AG has recently integrated new features that will make Adabas and Natural suitable for mobile development, DevOps, and big data environments.Footnote 3
