What Are Service Data Objects?

Service Data Objects (SDO) is a specification for a programming model that unifies data programming across data source types. Provides robust support for common application modules. Applications, tools, frameworks, etc. make it easier to add, delete, check, modify, constrain, and update data. SDO aims to create a unified and standardized data access layer and use a "easy to use" approach to integrate heterogeneous data sources into toolsets and frameworks. In short, SDO is designed to provide such a data object: Like plasticine, it can determine its actual performance based on the actual data source. It is not necessary to consider its actual type and construction method during use. ^[1]
