On June 23 2016, the people of the United Kingdom voted to leave the European Union. This unexpected referendum result – commonly referred to as Brexit – came as a surprise to many observers across the Channel. Thankfully, the decision not to support SAP Business Explorer (BEx) in SAP BW/4HANA —let’s call it the SAP Business Explorer it strategy!—didn’t come as such a surprise to long-time SAP Business Warehouse (BW) users.

Every March, the world’s largest IT event CeBIT showcases the latest technology innovations. The SAP “chancellor demo” has become almost a tradition, and 2017 was no exception. With Japan, one of the world’s largest and most innovative economies, being the official partner country of the event, our demo was not only presented to Germany’s Chancellor Merkel, but also to Japan’s Prime Minister Abe – and it was powered by SAP HANA.
The demo this year focused on how data can help anticipate natural events and take necessary action where needed. It showed how the risk of landslides can be predicted: With publicly available geo data (e.g. from the European Space Agency) analyzed with the SAP HANA Earth Observation Analysis Service running on the SAP HANA platform, areas of risk can be identified and assessed. The results can help governing authorities and local emergency services to optimize rescue planning and even take preventive measures.

A good understanding or a good description of a problem is a prerequisite to finding a solution. In this blog, I want to introduce just such a problem description for a data platform that is used for analytic purposes. Traditionally, this is called a data warehouse (DW), but labels, such as data mart, big data platform, and data hub  are also used in this context. I’ve named this problem description the Data Warehousing Quadrant. (An initial version has been shown in this blog.)
Since then, I’ve used it in many meetings with customers, partners, analysts, colleagues and students. It has the nice effect that it makes people think about their own data platform (problem) as they try to locate where they are and where they want to go. This is extremely helpful as it triggers the…

Big Data and Fast Data are solving IT challenges long thought to be unreachable. Think of Big Data as an amount of data so large and complex that traditional database management tools are useless. Fast Data, on the other hand, is when that data is put into motion to quickly gather and mine structured and unstructured data so that action can be taken.

Together, Big Data and Fast Data are opening up exciting opportunities. At the same time, this "Big and Fast" wave is pushing the boundaries of the technologies and frameworks we've tended to use for awhile.

In case you didn’t hear,
There’s no way to overstate the importance of this technology. For nearly any use case you can think of, hierarchies are required to know where everything is. SAP Vora enables that organization.
For this reason, SAP Vora was groundbreaking when we first announced it. But this latest version is a critical milestone in the development of the SAP distributed computing platform. Initial SAP Vora versions were primarily SQL on Hadoop, but the vision was to develop a multi-data type and multi-language data processing engine on Hadoop.  Although Hadoop is highly scalable, it is a challenging infrastructure to manage, as…

LINQ has many benefits over SQL, but at what cost?

Benchmark Results

Let’s get straight to the results!

Method | Median | StdDev | ------------------ |------------ |---------- | QueryLinq | 175.8261 us | 9.9202 us | QuerySql | 62.2791 us | 5.4908 us | QueryLinqCompiled | 57.9274 us | 3.1307 us |

Code is at github.com/ptupitsyn/IgniteNetBenchmarks.

This is a comparison of equivalent queries via SQL, LINQ and Compiled LINQ. Query is very simple (select Age from SqlPerson where (SqlPerson.Id < ?)), data set is very small (40 items, 20 returned): this exposes LINQ overhead better.

We can see right away that LINQ is a lot slower than raw SQL, but compiled LINQ is a bit faster. Note that results are in microseconds: real-world queries may take tens or even hundreds of milliseconds, so LINQ overhead will…
