• Concept of temporal data retrieval: Undefined value management by Michal Kvet, Štefan Toth, and Emil Kršák discusses the complexity of the temporal data retrieval process in the temporal environment, focusing on undefined value management: https://onlinelibrary.wiley.com/doi/epdf/10.1002/cpe.5399

• The Complexity of the Data Retrieval Process Using the Proposed Index Extension by Michal Kvet and Jozef Papán deals with an index extension to ensure the performance of the select statement. The performance optimization techniques are based on limiting migration rows, post-indexing, data pointer reflectors, and priority management by introducing architecture enhancements. It is published in the IEEE Access journal and is open-access: https://ieeexplore.ieee.org/document/9763539
