The digital transformation sets new requirements to all classes of enterprise systems in companies. ERP systems in particular, which represent the dominant class of enterprise systems, are struggling to meet the new requirements at all levels of the architecture. Therefore, there is an urgent need to reconsider the overall architecture of the systems and address the root of the related issues. Given that many restrictions ERP pose on their adaptability are related to the standardization of data, the database layer of ERP systems is addressed. Since database serve as the foundation for data storage and retrieval, they limit the flexibility of enterprise systems and the chance to adapt to new requirements accordingly. So far, relational databases are widely used. Using a systematic literature approach, recent requirements for ERP systems were identified. Prominent database approaches were assessed against the 23 requirements identified. The results reveal the strengths and weaknesses of recent database approaches. To this end, the results highlight the demand to combine multiple database approaches to fulfill recent business requirements. From a conceptual point of view, this paper supports the idea of federated databases which are interoperable to fulfill future requirements and support business operation. This research forms the basis for renewal of the current generation of ERP systems and proposes to ERP vendors to use different database concepts in the future.

数字化转型对公司的各类企业系统提出了新的要求。特别是 ERP 系统，它代表了企业系统的主导类别，正在努力满足架构各个级别的新要求。因此，迫切需要重新考虑系统的整体架构并解决相关问题的根源。鉴于 ERP 对其适应性的许多限制与数据的标准化有关，因此解决了 ERP 系统的数据库层。由于数据库是数据存储和检索的基础，因此它们限制了企业系统的灵活性以及相应地适应新需求的机会。到目前为止，关系数据库被广泛使用。使用系统的文献方法，确定了最近对 ERP 系统的要求。针对已确定的 23 项要求评估了突出的数据库方法。结果揭示了最近数据库方法的优点和缺点。为此，结果强调了结合多种数据库方法来满足近期业务需求的需求。从概念的角度来看，本文支持联邦数据库的想法，这些数据库可以互操作以满足未来的需求并支持业务运营。这项研究构成了更新当前一代 ERP 系统的基础，并建议 ERP 供应商在未来使用不同的数据库概念。结果强调了结合多种数据库方法以满足近期业务需求的需求。从概念的角度来看，本文支持联邦数据库的想法，这些数据库可以互操作以满足未来的需求并支持业务运营。这项研究构成了更新当前一代 ERP 系统的基础，并建议 ERP 供应商在未来使用不同的数据库概念。结果强调了结合多种数据库方法以满足近期业务需求的需求。从概念的角度来看，本文支持联邦数据库的想法，这些数据库可以互操作以满足未来的需求并支持业务运营。这项研究构成了更新当前一代 ERP 系统的基础，并建议 ERP 供应商在未来使用不同的数据库概念。
