3. Elasticsearch:
   Acts as the backend storage for indexed log data, enabling fast search and retrieval.
4. MongoDB:
   Stores configuration data, such as user settings, input definitions, and alert configurations.
5. Web Interface:
   Provides a graphical dashboard for querying logs, creating visualizations, and managing alerts.
6. Plug-and-Play Integrations:
   Support for numerous data sources and plugins ensures flexibility in deployment.

CasinoBeats Malta Digital is to reflect the crucial role that affiliates continue to play in the online casino industry by making the future of igaming affiliation one of the key themes of the agenda for the three-day virtual conference and exhibition.

The content will feature insights and ideas from some of the leading executives in the sector, while there will also be plenty of networking opportunities for affiliates and operator affiliate managers during the event, which takes place on 30 June – 2 July 2020.

Among the key sessions is the Affiliate Leaders Panel, sponsored by Intertops, which has a speaker line-up that includes Tobias Svensen (CEO, CasinoGrounds), Hamish Brown (VP casino, Catena Media), Jonathan Edelshaim (general manager, Natural Intelligence) and Marcos Oliveira (chief affiliate officer, Clever Advertising Group).

It will examine the challenges facing major igaming affiliates, the ways in which the changing regulatory climate is influencing how affiliates operate, and what opportunities are available to new entrants to the market. 

Another highlight is the Acquisition & Personalisation session, which will see a panel including Assaf Stieglitz (founder, Odds1x2.com) share their experiences of the most effective methods for the slots sector to acquire new players and optimise the lifetime value of customers. Panelists will also outline their thinking on how these techniques may evolve as the market continues to change.  

Delegates can also look forward to some practical advice during the Affiliates: Compliance Minefield session, as a panel that includes Ian Sims (founder, Rightlander) details how  igaming affiliates can stay simultaneously onside with advertising guidelines, operator policy and regulatory requirements. 

In addition to the marketing-focused sessions, there will be panels on other topics of interest to affiliates, such as developments in the Japanese and Swedish markets, and the long-term outlook for live casino, online poker and bingo.   

Away from the conference rooms, operator affiliate managers and delegates from affiliates will have lots of opportunities to connect during CasinoBeats Malta Digital. The event has a virtual networking lounge, a virtual bar and one-to-one chat functionality, along with a selection of themed networking hours designed to bring together stakeholders interested in specific market sectors. The schedule will include a dedicated affiliate session. 

Stewart Darkin, managing director of CasinoBeats, said: “We’ve chosen to make affiliate marketing a central theme for the event in recognition of the fact that igaming affiliates remain an important part of the online casino ecosystem. 

“The strategies affiliates use to achieve results for operators are constantly evolving, and delegates attending the conference sessions will discover plenty of new perspectives on the coming trends and long-term future of the sector. 

“The event will also provide a relaxed setting for operators to connect and talk business with both market-leading super affiliates and innovative new affiliates.” 

CasinoBeats Malta Digital will see 3,000 industry delegates, including more than 1,200 representatives of major casino, slots and poker operators, gather for a five-track conference, interactive exhibition featuring 40 leading suppliers, and selection of virtual networking events.

Business intelligence (BI) is nothing new to enterprises that have been relying on data processing and analysis to deliver insightful reports that reflect business performance.

These tools are a great match for enterprises that value the data their operations generate.

BI software and programs work together to turn data into actionable insights that can drive better business decisions and market strategies and, ultimately, drive revenue as a result.

Combined with the masses of external data amassing every second – whether that’s customers’ feedback and experience, competitor intelligence, seasonal buying habits, or otherwise – businesses can have a huge amount of data at their disposal.

While BI systems draw specific data from pre-defined sources to turn them into insights, big data technologies capture data from a variety of sources in real-time, regardless of their formats or structure.

Unlike BI, big data doesn’t answer critical questions that enterprises have, but rather, it provides them with new information that can prompt new questions that enterprises haven’t thought of asking.

Once enterprises have a better idea of what they want to find out, they can turn to BI tools to deliver the insights, and even make predictions.

Business impact

Since big data came into the picture, BI becomes just that much more conducive.

Through big data, BI can now deliver insights that enable businesses to better understand their customers, improve marketing techniques, make personalization possible and identify issues and opportunities that emerge in real-time.

Marketing strategies no longer have to a shot in the dark. With data varying from customer feedback to their journey records, enterprises can market products with a clear understanding of what customers want and need.

Enterprises can then leverage data alongside real-time market analysis data to develop and deliver new and improved products and services.

Big data technologies can help businesses augment their operations. Data doesn’t have to be externally sourced, it can come from internal systems and programs as well.

Siloes between teams and hiccups in workflows can be detected in real-time, allowing enterprises to redesign their processes effectively.
