Editing ADABAS (section)

==Non-relational==
In a 2015 white paper, IBM said: "applications that are written in a pre-relational database, such as Adabas, are no longer mainstream and do not follow accepted IT industry standards".<ref>{{cite web |title=Converting Adabas to IBM DB2 for z/OS |url=http://www.redbooks.ibm.com/redpapers/pdfs/redp5154.pdf}}</ref> However, an Adabas database can be designed in accordance with the relational model. While there are tools and services to facilitate converting Adabas to various relational databases,<ref>{{cite web |title=ADABAS Database Migration to IBM DB2, Oracle, Microsoft SQL Server

===Hardware zIIP boost===
IBM's [[zIIP]] (System z Integrated Information Processor) special purpose processors permit "direct, real-time SQL access to Adabas" (even though the data may still stored in a non-relational form).<ref>{{cite web |url=http://www.rocketsoftware.com/sites/default/files/resource_files/WP_Data_Adabas-Data-Virtualization.pdf |title=5 Ways to Simplify Access to Adabas & Natural with Data Virtualization |date=1990}}</ref>
