SAP HANA Vora is a Newly introduced SAP solution for analyzing large data in memory on the Hadoop platform which is running on an in-memory computing engine. SAP HANA Vora is an interactive big data analysis engine from SAP that connects to the Apache Spark and Hadoop system to improve accessibility and usability of big data from Hadoop. In the final analysis, companies can use data analytics, KPI, Service to improve their results.
Introduction for SAP HANA Vora
Data scientists and analysts use data analytics tools and companies use them in their decisions making. Data analysis will assist businesses in better understanding their client’s business & areas of improvement, evaluating their advertising campaigns, personalize content for marketing, develop content strategies, and develop new products. Hence Big Data analytics showcases several insights to grow and to provide an edge over their competitors.
SAP Vora supports a wide range of data types including graph data, relational data and JSON, time series, A specialized engine manages each type of data with internal data structures and algorithms that can natively support and efficiently process it.
We can load relation information into the main memory and then quickly access the code using query processing. There are various engines processed remaing data for subsequent analysis .
- The relational disk engine handles large data sets that cannot be fit into the main memory.
- The time series engine can compress time series data using different compression techniques. It also provides algorithms such as cross-correlation or histogram computation for the compressed data.
- Graph engine allows you to perform common operations on graph data. It is particularly well-suited for complex read-only queries on large graphs. The document store supports rich query processing of JSON data
Before we start a deep drive on HANA Vora, We need to understand the concepts Big data, HADOOP & Apache Spark
What is Big Data
Mobile sensing, air (remote sensing), cameras, microphones, RFID readers and networks of wireless sensors, social media, and archived data. Enterprise data is usually stored in costly hardware, and large data in the less expensive distributed commodity hardware is stored.
What is HADOOP
Distributed computing open-source software. HADOOP does the following when you want to save huge volumes of data in a distributed landscape. HADOOP supports you in creating a distributed environment through the combination of multiple landscape systems. HADOOP assists in distributing data and load processing to various scenarios. HADOOP works only on one layer above Operating System, using Hadoop Distributed File System. Distributed computing (HDFS). H
HADOOP, therefore, handles files for the data. In most cases, when it is stored in an unstructured file format, data can not be processed easily. So to structure data we need some software. We always organize data files using software like MySQL, ORACLE, DB2, and so on in our traditional systems. In the same way, we need some software to structure HDFS files,
HANA VORA helps resolve both problems and bridges the corporate big data gap. Corporate data is data from current business transactions like orders for sale, purchase orders, etc.
What is Apache Spark
In layman language, it’s in-memory data processing & its very quick data processing capacities. Its support Multiprogramming languages like Scala, Python, and Java support the Apache Spark and Vora system. As the Scala language used in Apache Spark is currently the most common. Vora will expand Apache Spark by providing additional business features and the best possible integration with SAP HANA, enabling cross-consumption reporting and advanced analysis, using the live corporate data from an organization.
Spark offers further advanced feasibility for the machine learning algorithms related to Spark Streaming and Machine Learning (MLlib).
Challenges in data analysis.
- Major challenges we have faced as soon as we must have BIG data
- Distributed data is stored in a complicated analysis environment in which the query results are not good every time
- It will be very demanding for the reports requiring the combination of business and big data because of the different landscape of both data.
What is HANA VORA
HANA Vora uses the in-memory database of HANA that can be processed in real-time and then adds a layer in the analysis to handle Hadoop data. This allows Vora to collect huge amounts of data stored in Hadoop so that developers and data analysts can immediately access the aggregated data and make context-aware decisions.
To handle specific business scenarios for the digital enterprise, SAP developed SAP Vora from SAP HANA. In September 2015, SAP HANA Vora was released on on-premises and in the cloud. Hadoop offers less cost storage for vast amounts of data, but acceptance lagged in the company initially because the data in a data lake is unstructured and difficult to handle.
To enable OLAP-style memory analysis of the combined data via the Apache Spark structured query language (SQL) interface, SAP HANA Vora builds structured data hierarchies for the Hadoop datasets and integrates them with HANA data.
Why HANA VORA
For example, by rapidly detecting transaction and Client History Anomalies, a financial institution may reduce risk and frauds by better-analyzing network traffic patterns to prevent bottlenecks and improve service quality (QoS), or a financial institution might be allowed to mitigate fraud; By analyzing materials bill (BOM), manufacturing data and sensor data, the manufacture could improve its product recall process.
SAP HANA Vora is a memory query engine that connects to the execution framework of Apache Spark to provide enhanced Hadoop interactive analysis.
SAP Vora Engine Architecture
SAP Vora supported various data types, including relation data, graph data, JSON document collections, and time series. A specialized engine manages each data type with tailored internal data and algorithms to support this data type natively and efficiently.
HANA Vora allows to load of relational data into main memory for quick access via query processing, code generation using different compression techniques while providing algorithms such as cross-correlation or histogram on the compressed data. Graphical operations on the data and is especially suitable to handle very large charts for complex read-only analytical queries
SAP Vora can load data from externally distributed stores, such as SAP BW, ERP & Non SAP Source like IoT, Social Media, log & Remote sensors. Data is either stored in the memory or indexed and stored on the hard discs. Allow batch data processing, Analyzing & transformation complex logic prepare data before query execution & Represent in a visual format
