Why do we need Social Media Analytics?

Social Media Analytics transforms raw data from social media platforms into insight, which in turn leads to new business value.

What will your learn in this sessions?

Once you dive into Social Media Analytics, how do you bring it to the next level? Social data can offer powerful insights right away. In this session, you will learn how to build a mature social data program from that foundation and strategies for scaling a social data programme, as well as how to connect directly to your social media data with a web data connector; considerations for building scalable data sources; and tips for using metadata and calculations for more sophisticated analysis.

Data Operations: Daten für die Analyse optimal vorbereiten

#dataops: Folgen Sie der Diskussion auf Twitter
#dataops: Folgen Sie der Diskussion auf Twitter

Kürzlich habe ich einige Blog-Posts zum Thema Datenstrategie veröffentlicht. Für viele Unternehmen geht die Entwicklung und Einführung einer Datenstrategie nicht tief genug. Häufig habe ich ähnliches gehört: “So weit ist unser Unternehmen noch gar nicht. Wir haben noch viel operativ vorzubereiten, bevor wir eine Datenstrategie voll umfänglich etablieren können.”

Ich habe in diesen Gesprächen nachgehakt, wo diese grundlegenden Lücken in den Unternehmen bestehen, und entschlossen eine neue Blog-Post-Serie aufzusetzen, um zum Thema Data Operations (#dataops) konkrete und einfach umsetzbare Vorschläge zu geben.

Daten für die Analyse vorbereiten

Eine der wesentlichen Fragen, die sich Datenanalysten immer wieder stellen, lautet: “Gibt es eine Möglichkeit meine Daten für die Verwendung mit Analysewerkzeugen, wie Tableau, optimal vorzubereiten?”

Daten können auf unterschiedliche Arten strukturiert sein. Die meisten neuen Tableau-Anwender erliegen der Versuchung, Tableau mit einem bereits formatierten und voraggregierten Excel-Bericht (siehe Abbildung 1.1) zu verbinden und diesen in Tableau zu visualisieren. Heißt es nicht mit Tableau können Daten jeder Art einfach und intuitiv verwenden werden? Sehr schnell stellt man fest, dass ein solches Vorgehen nicht funktioniert, wie erwartet und sich so auch keine Visualisierungen erstellen lassen.

Dieses Szenario, dem viele Einsteiger begegnen, ist nicht ungewöhnlich und tatsächlich ein häufiger Stolperstein bei der Einarbeitung in Tableau, der die Analyse Ihrer Daten erschweren kann.

Die folgenden Punkte zeigen Ihnen Vorschläge zur sauberen Vorbereitung Ihrer Daten anhand des Beispielberichts:

  • Verzichten Sie auf den einleitenden Text (“Temperaturmessung zum Monatsbeginn”).
  • Überführen Sie hierarchische Überschriften (“Frankfurt”, “Berlin”) auf eine Spalteninformation (neue Spalte “Ort”).
  • Pivotisieren Sie Daten von einer “weiten” Kreuztabelle mit Variablen in Spalten (“Früh”, “Mittag”, “Abend”) in eine “lange” Tabelle, die die Variablen stets in den Zeilen trägt (in diesem Beispiel die Uhrzeit).
  • Nutzen Sie vollständige Datums- und ggf. Zeitformate (“01.04.2018 06:00”) anstatt z.B. nur den Monatsnamen (“April”).
  • Überprüfen Sie, dass Zahlen im Zahlenformat und nicht im Textformat gespeichert sind.
  • Verzichten Sie voraggregierte Daten (“Durchschnitt”, “Gesamtdurchschnitt”).
  • Entfernen Sie leere Zeilen.
  • Achten Sie darauf, dass jede Spate eine aussagekräftige Spaltenüberschrift trägt.

Haben Sie diese Vorschläge befolgt, ist aus Ihrer “weiten” Kreuztabelle nun eine “lange” Zeilen-basierte Tabelle geworden, und damit die perfekte Basis zur umfangreichen Datenanalyse (siehe Abbildung 1.2).

Leadership: Stagnation Kills Your Business, 3 Times

Your business has been thriving, and the pipeline is well filled with work? Don’t get comfortable too soon. Stagnation kicks in fast nowadays, and kills your business’ innovation, its growth, and its people.

1. Innovation 

The speed of transformation that we are currently witnessing is challenging all of us to think differently. Every industry can be disrupted, there is no safe habour. So we need to deliver our products and services in a way that is relevant today, not yesterday.

Minor product iterations do not work forever. We need to prepare product revolutions, not just iterations on what we were selling since ten years. Establishing an innovation lab engages our employees to think in innovative ways and lift our business to new heights.

2. Growth

We need to adjust our business development plan to drive business growth. This should not be a static document. Customer and market definition are changing fast and we need to adopt this in our sales strategy and in our product development.

This does not work without data. Therefore we need to implement a data strategy. Our data strategy guides our entire business how to collect and analyze data, and how to generate the insights that we use for our decisions. If we do not take advantage of data, our competition will do.

3. People

Sushi Google DoodleIt is essential for leaders to recognize that you cannot possibly manage everything. We need to employ great people. But recruiting is not the end. We need to keep your talents, empower them, and motivate them to take initiative in their roles. Stagnation will rotate employees out of the company.

Offering free sushi and laundry service might impress our new hires from university. Experienced and independent employees will be more interested in career perspectives. We should establish personal development plans for everyone, not just for the designated managers.

Although it is important for leaders to set such a career framework, we should not forget to invest in your employees’ training. Both, hard skills (technical) and soft skills (non-technical), are mandatory because they each play very important roles in the development of our employees.

In Summary

Yesterday’s innovations are tomorrow’s commodities. We need to invest in innovations, otherwise we will face disruptive competition. Creating insights from data is important for the iterative adjustments on our business development plan. Offering personal development plans and proper training avoids stagnation for your employees, which is causing brain drain.

5 Takeaways from Tableau’s Hybrid Transactional/Analytical Processing

What makes Hyper so fast?
The Future of Enterprise Analytics: Hyper can handle both OLTP and OLAP simultaneously. In the future it will address NoSQL and graph workloads.

1. What is Hyper’s key benefit?

Hyper is a Hybrid transactional/analytical processing (HTAP) database system and replaces Tableau Data Extracts (TDE). The change will be mostly transparent for end users, other than everything being faster. Hyper significantly improves extract refresh times, query times and overall performance.

2. What is Hybrid transactional/analytical processing?

As defined by Gartner:

Hybrid transaction/analytical processing (HTAP) is an emerging application architecture that “breaks the wall” between transaction processing and analytics. It enables more informed and “in business real time” decision making.

The two areas of online transaction processing (OLTP) and online analytical processing (OLAP) present different challenges for database architectures. Currently, customers with high rates of mission-critical transactions have split their data into two separate systems, one database for OLTP and one so-called data warehouse for OLAP. While allowing for decent transaction rates, this separation has many disadvantages including data freshness issues due to the delay caused by only periodically initiating the Extract Transform Load (ETL) data staging and excessive resource consumption due to maintaining two separate information systems.

3. Does Hyper satisfy the ACID properties?

Hyper, initially developed at the Technical University of Munich and acquired by Tableau in 2016, can handle both OLTP and OLAP simultaneously. Hyper possesses the rare quality of being able to handle data updates and insertions at the same time as queries by using hardware-assisted replication mechanisms to maintain consistent snapshots of the transactional data. Hyper is an in-memory database that guarantees the ACID properties (Atomicity, Consistency, Isolation, Durability) of OLTP transactions and executes OLAP query sessions (multiple queries) on the same, arbitrarily current and consistent snapshot.

4. What makes Hyper so fast?

The utilization of the processor-inherent support for virtual memory management (address translation, caching, copy on update) yields both at the same time: unprecedentedly high transaction rates as high as 100,000 per second and very fast OLAP query response times on a single system executing both workloads in parallel. This would support real-time streaming of data in future releases of Tableau. These performance increases come from the nature of the Hyper data structures, but also from smart use of contemporary hardware technology, and particularly nvRam memory. Additional cores provide a linear increment in performance.

5. What does this mean for Tableau?

With Hyper now powering the Tableau platform, your organization will see faster extract creation and better query performance for large data sets. Since Hyper is designed to handle exceptionally large data sets, you can choose to extract your data based on what you need, not data volume limitations. Hyper improves performance for common computationally-intensive queries, like count distinct, calculated fields, and text field manipulations. This performance boost will improve your entire Enterprise Analytics workflow.
