Abstract: A method for storing data in a table of a database system is disclosed. The table comprises a first column and a second column. The first column is configured for comprising first type data. The second column is configured for comprising second type data, wherein the second type data has a maximum size higher than a maximum size of the first type data. The method comprises: receiving a query to store a record in the table. It may be determined whether the record comprises a value of the second column. In case the record comprises the value of the second column, the value may be stored in a version control system and a reference token representing the value may be stored in the second column of the table. In case the record does not comprise the value of the second column, the record may be stored in the table.

Abstract: The present disclosure relates to a method for executing a query against a table of a database system, the table being configured to comprise records. The record comprises values of a set of columns, wherein one or more changes are being applied to the table in order to be synchronized with a corresponding table. The method comprises: receiving a query against the table, the query referencing one or more columns of the set of columns. It may be determined whether the application of one or more changes involving the one or more columns is completed. In response to determining that said one or more changes are applied, the query may be executed.

Abstract: The present disclosure relates to a method for execution of an application comprising a sequence of components. The first component is configured to store output data in an unused buffer and each subsequent component is configured to use a buffer comprising an output provided by the component preceding said subsequent component. The method comprises: providing a set of buffer states representing different contents of the buffer respectively, the set of buffer states comprising an initial state representing a content of the unused buffer and subsequent states representing the outputs of the sequence of components respectively. The buffer states may be sorted, wherein the sorting is circular so that a final state is followed by the initial state. During execution of the application a current state of a buffer may be changed to a subsequent state in case the current application component using the buffer finishes.
