Abstract: Implementations of the present disclosure include receiving, by a parser, a view source file and an extension source file, the view source file defining a view on data stored in a database, the extension source file defining an extension to the view, parsing, by the parser, the view source file to provide a view abstract syntax tree (AST) and the extension source file to provide an extension AST, providing, by the parser, a merged AST based on the view AST and the extension AST, generating a mixed runtime data object using the merged AST, and providing the mixed runtime data object for consumption by at least one runtime component.

Abstract: The present disclosure involves systems, software, and computer implemented methods for ensuring seamless lifecycle stability for extensions to standard software products. One example method includes determining a requested change to a software feature of a software object. The software feature has been designated as an extensible software feature and is associated with a lifecycle stability contract that identifies aspects of the extensible software feature that are designated to remain stable across different releases of the software object. The lifecycle stability contract is used to perform a compatibility check for the requested change to determine whether the requested change complies with the lifecycle stability contract. The requested change is permitted in response to determining that the requested change complies with the lifecycle stability contract and the requested change is denied in response to determining that the requested change violates the lifecycle stability contract.

Abstract: Methods, systems, and computer-readable storage media for include receiving, by a parser, a view source file and an extension source file, the view source file defining a view on data stored in a database, the extension source file defining an extension to the view, parsing, by the parser, the view source file to provide a view abstract syntax tree (AST) and the extension source file to provide an extension AST, providing, by the parser, a merged AST based on the view AST and the extension AST, generating a mixed runtime data object using the merged AST, and providing the mixed runtime data object for consumption by at least one runtime component.

Abstract: The present disclosure involves systems, software, and computer implemented methods for enabling data source extensions for individual customers of a cloud platform. One example method includes receiving an extension request, from a particular customer, to extend a data source used to populate an application output. A selection is received of at least one field to be included in a data source extension that extends the data source. Extensibility metadata is stored, in association with the particular customer, that defines the data source extension. The extensibility metadata identifies the data source, the particular customer, and the selected at least one field. A data request is received, from a client device of a user of the customer, for a field included in the data source extension. The data source extension is used to retrieve a field value for the field and the field value is provided in response to the data request.
