Last position:
ERP Program Manager at Fiserv
The customer is undergoing a comprehensive transformation. All SAP ECC landscapes worldwide are being migrated to SAP S/4HANA, with the goal of introducing a standard template worldwide.
The program also includes the “RISE with SAP” migration and modernization program, which may involve migrating the landscapes of selected country installations to the SAP Private Cloud.
On the stakeholder side, the program reporting line extends to the company’s executive board and that of the implementation partner.
Fiserv Germany’s ERP landscape currently includes several non-standard SAP tools and applications that extend the functionality of the ECC environment and can often be integrated into downstream systems. As part of the transition to SAP S/4HANA, it is essential to assess the core functionality, integration points and future viability of these applications in order to determine their alignment with the target architecture.
The focus of the work is on providing expert advice and assessment to define the scope, strategy and roadmap for transitioning Fiserv Germany’s SAP ECC system to SAP S/4HANA.
The recommended best practices from SAP are followed and a structured approach is used to ensure a smooth transition with minimal disruption while maximizing business value.
This assessment forms the basis for a successful SAP S/4HANA transformation and ensures alignment with industry best practices, regulatory compliance and future scalability.
Migration Strategy Definition – assessment of available transition approaches based on business objectives, technical feasibility and SAP Best Practices.
Technical Readiness Assessment – conducting a system analysis to assess compatibility, custom code impact, data volume management, integration points and infrastructure readiness for SAP S/4HANA.
Business Process Impact Analysis – reviewing the latest business process documentation to define the scope and effort required to implement the necessary functions in SAP S/4HANA and to identify opportunities for process optimization.
Roadmap for Non-SAP Systems and Applications – assessment of third-party and legacy applications regarding their integration with SAP S/4HANA and recommendation of consolidation, migration or replacement strategies.
Deployment & Implementation Planning – defining a phased approach for implementation, including project schedules, risk mitigation strategies and key milestones aligned with business priorities.
This transformation takes place in phases: the Discovery phase leads to the Explore phase, which is followed by the Design phase and finally implementation.

About the technology
What ODBC does
ODBC, short for Open Database Connectivity, is a standard interface for connecting applications to relational databases. It separates application logic from database-specific access through drivers, allowing software to work with systems such as Microsoft SQL Server, PostgreSQL, MySQL, Oracle Database and many other data sources. Companies use it for reporting, integrations, migrations and operational tools.
Drivers and components
An ODBC connection typically includes an application, the ODBC Driver Manager, a vendor driver and a data source configuration. Specialists work with DSNs, connection strings, driver versions, authentication methods, TLS settings and connection pooling. They also distinguish between user and system data sources and account for differences between Windows and Unix-like environments.
Common delivery work
- Configure secure connections between applications and SQL databases
- Replace outdated drivers or migrate DSN-based setups to managed configuration
- Improve queries, transaction handling and connection pooling
- Build reporting and export workflows across multiple data sources
- Diagnose failures in batch jobs, integrations and desktop applications
ODBC often appears in finance, manufacturing, logistics, retail and public-sector systems where established applications still depend on stable database access. In Germany, specialists may support regulated or operational environments through remote collaboration, on-site workshops or a combination of both.
When expertise helps
Companies bring in freelance ODBC expertise when a connection works on one machine but fails elsewhere, a database migration disrupts reporting, or a legacy application must remain reliable while its surrounding systems change. External specialists can trace errors across the application, driver and database layers instead of treating every failure as a query problem. They can also document configuration that has become difficult to maintain.
Adjacent skills
Useful experience extends beyond the interface itself. Strong professionals understand SQL, relational data modelling, database permissions, query plans, ETL processes, scripting and application logging. They may also work with JDBC, ADO.NET, Python database libraries, Power BI, Excel, SSIS or cloud-hosted databases when ODBC is part of a wider integration landscape.
Signs of quality
- Tests driver compatibility across target operating systems and database versions
- Uses parameterized queries and least-privilege credentials
- Measures connection, query and transfer behaviour before changing configuration
- Separates application errors from driver, network and database errors
- Leaves repeatable setup steps, monitoring guidance and clear documentation
The best specialists explain trade-offs in plain language and validate changes with representative workloads. They treat reliability, security and maintainability as part of the deliverable, not as optional cleanup after a connection has been established.
Frequently asked questions
Need clarity? These are the questions we hear most often about ODBC.
ODBC connects applications to relational databases through a common interface and database-specific drivers. Companies use it for reporting, data exports, integrations, desktop tools, batch processing and access to legacy systems.
ODBC is language- and vendor-neutral, which makes it useful when one application must access different database systems. JDBC is designed for Java applications, while native drivers may expose more vendor-specific features but can create tighter coupling.
A strong ODBC specialist usually brings SQL, relational database, authentication and troubleshooting skills. Experience with connection pooling, ETL tools, scripting, logging, Windows and Linux configuration is also valuable, depending on the application.
The right level depends on the assignment. A simple DSN or driver configuration needs less background than a migration involving legacy applications, high-volume transfers, security controls and several database vendors. Ask for examples of comparable environments and documented problem-solving.
ODBC work is often suitable for remote collaboration because configuration, logs, connection tests and documentation can be reviewed securely online. On-site sessions may still help when systems are isolated, access is restricted or teams need workshops in Germany.
Typical ODBC failures come from mismatched driver architecture, incorrect DSNs, unsupported authentication, expired credentials, network restrictions or incompatible settings. A careful specialist checks each layer separately and reproduces the issue with the same account and environment.
Good ODBC work includes tested configuration, secure credentials, clear error handling and documentation that another professional can follow. Review whether the specialist measures performance, explains driver choices and tests failure scenarios rather than only demonstrating a successful connection.
ODBC remains useful when established applications, reporting tools or third-party systems need access to existing databases. Modernization may replace some connections with APIs or newer libraries, but a specialist can determine which interfaces should change and which should remain stable.
The average hourly rate of freelancers in Germany who have used ODBC in their recent projects is 91 €, which corresponds to a daily rate of about 727 € based on an 8-hour working day.
Of the freelancers in Germany who have used ODBC in their recent projects, 81% hold at least a Bachelor's degree, 44% hold at least a Master's degree, and 4% hold a doctorate.
