With Talend, everything ran perfectly from day one.

Landesbank Berlin AG (LBB) is a universal bank that can trace its roots back to 1818 when its affiliate, the Berliner Sparkasse savings bank, was founded. From the very outset, Berliner Sparkasse has been committed to serving the public interest. It is the market leader in Berlin, renowned for its strong customer ties, fair conditions, secure business base and modern approach to banking. The LBB’s business model is built on four pillars: private banking, corporate banking, commercial real-estate financing and selective capital market activities. Berliner Sparkasse serves around two million retail customers and approximately 69,000 corporate customers from over 200 branch offices in Berlin. Ever-rising account data volumes In order to cope with ever-rising data volumes, LBB wanted to modernize its existing core banking system. Implementing a new system, however, is the equivalent of open heart surgery for a bank. It requires thorough preparation long in advance. And the changeover must run without a hitch – if not, it can bring the entire bank to a standstill. In 2011, LBB successfully completed this challenging migration project. The Tools & Methods Framework (TMF) team and integration technology from Talend were key success factors. LBB is a member of Germany’s national savings banks group, an organization that comprises savings banks and state-owned banks (Landesbanken) as well as insurers and other companies. As such, it has access to the services offered by the organization’s central IT provider Finanz Informatik (FI). FI offers its own modern core banking system known as OSPlus and LBB was keen to switch to this solution. Because the central system supports all banking- related processes and transactions, any switch to a new system has far-reaching implications for the entire system landscape. FI offers OSPlus as a hosted solution as part of an all-round service package. In order to integrate its own banking applications for customer, address, revenue and account data, LBB needed to create an entirely new interface landscape parallel to OSPlus rollout. The bank wanted to use a standardized solution capable of converting a wide range of data formats. In OSPlus, for example, around two terabytes of data are generated every day and stored in a DB/2 database. LBB either stores this data or loads it to various applications, the majority of which are built on Oracle databases. “Our job is to provide colleagues in different departments with information. And we have to ensure that it comes in the right format for the target system,” explains Aliekber Akkoyun, head of the development team at LBB. “The data is transferred from database to database, or from a database to a file system – or vice versa. We also load data to web services and queues. Our previous integration platform was not up to the task of handling big data – it was just too much for it to handle,” recalls Jan Penné, systems architect at LBB responsible for the new integration platform. Why Talend? LBB needed a data integration platform that could meet all of these challenges. LBB’s team started evaluating solutions available on the market and came across Talend’s open-source platform in 2009. “We had been successfully using the SOA platform developed by Sopera before the migration project, and so we knew that Sopera and Talend collaborate closely. In fact, our decision to go with Talend proved an even smarter move for the bank when Talend acquired Sopera in the fall of 2010. It means that we now have a uniform
