How do clients look at the value of two of the top in-memory machines and database management systems in the market?

Oracle Exalytics and SAP HANA have certain similarities. Aside from being in-memory databases, both are modern applications and service analytic workloads.

Oracle Exalytics complements the existing Oracle Relational Data Base Management and Exadata database apparatus. It is a compilation of functional technologies integrated in the hardware.

It includes the Times Ten in-memory database, Essbase OLAP engine and Business Intelligence tools. It is a package put together by Oracle which offers light speed reporting through its BI solutions. It is primarily an aggregation mechanism where Business Intelligence inquiries can be made.

SAP HANA was developed as a complete transactional relational database management system (RDBMS). It complies with the properties of Atomicity, Consistency, Isolation and Durability. The system has immediate answers for hardware issues, data recovery (in case of disasters) and tolerance for errors. There is moderate scalability for massive volumes of workloads. At the same time, SAP HANA is capable of supporting Online Transaction Processing (OLTP) and Online Analytical Processing (OLAP) workloads. These are virtual faculties so you need not replicate data or maintain an independent reporting system. Once the data has been stored, it becomes available through other implements like Landscape Transformation, Data Services or Event Stream Processing. Reporting is done in real time because these are all meant for transactional purposes. 

What is the advantage of Exalytics?

It can make a call immediately if the hardware needs service repairs or parts replacement. The service engineer from Oracle responds right away to fix the problem even if the hardware is not supported by the corresponding software.

The other major advantage of Oracle is that it provides a complete product stack. This includes the hardware in the OS (operating system), applications server, and business intelligence tools.  Therefore, the configuration optimizes the software for a specific hardware configuration. For example, the primary release of Oracle Business Intelligence is part of the Exalytics software stack with performance optimization for one terabyte of Random Access Memory and 40 Central Processing Unit cores.

On the other hand, SAP has communicated clearly the evolution of its High Performance Analytic Appliance. SAP HANA is considered as having the most inventive database in the market. It has the capacity to combine and update huge volumes of data almost in real time.

The primary advantages of SAP HANA 

SAP HANA has in-memory technology which permits users to delve into and analyze data in real time practically from any source of data. The data access and integration services facilitate the access to and indexing of external data within the organization. Users can add them to current analytical models. Real-time analytical processing is conducted to assess business operations in making use of large volumes of comprehensive information in the midst of operations. Moreover, data can be amassed from multiple applications and different data sources without interfering in present business transactions.

The business information can be stored using the Persistent Data Repository and recovered in case a breakdown occurs. Replication Service may be employed to access and copy data from SAP Enterprise Resource Planning. There is rigid integration with SAP Business Objects and business intelligence solutions mainly for purposes of analytics.

More so, there are innovations lined up by SAP HANA for 2014.

Conclusion 

SAP HANA is progressing towards a provider of multi-layered platforms in three major areas. These are database programs, business intelligence analytics and the mobile field. Furthermore, there is compute power development and event streaming. These are expected to make more headway in the industry. For its part, Oracle projects a large data forecast for 2014. It is seen as a big year for Business Intelligence and Times Ten as well as the Oracle database. There will be fewer risks in using Exalytics as the in-memory storage platform while deriving more benefits from the massive memory.
