Uniform interface access implementation method and equipment for relational database and medium

The invention relates to a unified interface access implementation method and device for a relational database and a medium, and the method comprises the steps: carrying out the effective packaging of each basic object component through employing an object-oriented programming technology, and providing a universal and standardized consistent development call interface (OCI); according to the standard language of the relational database, SQL standard statements are executed, an access data set is inquired or a database operation process is executed, and interface access is unified; according to the requirements of different operating systems, the method supports adaptive selection of Unix, Linux and Windows operating systems for compiling, and realizes an object-oriented interface cross-platform function; according to the requirements of different programming languages, a C + +/C language is used as a basis, and further packaging is performed to adapt to the programming requirements of different languages, so
