ABAP vs. C# vs. NoSQL vs. XML Comparison Chart

ABAP (Advanced Business Application Programming) is SAP’s proprietary fourth‑generation programming language, purpose‑built for mass data processing in SAP business applications. Utilized within SAP NetWeaver, it enables companies running SAP ERP and S/4 HANA to tailor systems precisely to their needs. ABAP is a multi‑paradigm language that supports procedural, object‑oriented, and other programming styles. It can seamlessly interoperate with languages such as Java, JavaScript, and SAPUI5. ABAP embraced object orientation with release 4.6C (2000) and saw even greater efficiency gains in ABAP 7.4/7.5, cutting code length by up to 50% via richer syntax, enhanced Open SQL, ABAP Managed Database Procedures, and Core Data Services (CDS) Views. The arrival of SAP HANA in 2011 shifted much processing into the in‑memory database layer, enabling real‑time operations and unlocking powerful new programming possibilities.

NoSQL is a domain-specific programming language used for accessing, managing, and manipulating non-tabular databases. A NoSQL (originally referring to "non-SQL" or "non-relational") database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases. Such databases have existed since the late 1960s, but the name "NoSQL" was only coined in the early 21st century, triggered by the needs of Web 2.0 companies. NoSQL databases are increasingly used in big data and real-time web applications.NoSQL systems are also sometimes called Not only SQL to emphasize that they may support SQL-like query languages or sit alongside SQL databases in polyglot-persistent architectures. Many NoSQL stores compromise consistency (in the sense of the CAP theorem) in favor of availability, partition tolerance, and speed. Barriers to the greater adoption of NoSQL stores include the use of low-level query languages.
