**How classified:**

- **C (Create)**: Methods `addSOD` and `tsuikabunAddSOD` insert records into `KK_T_ODR_HAKKO_JOKEN` (Order Issuance Option Detail) with various `ODR_NAIYO_CD` codes (101-254). The `addSOD` method specifically creates SOD (Service Order Data) documents with the specified content code.
- **R (Read)**: Methods with names starting with `callEKK*`, `get*`, or similar read patterns query service agreement data from the database. The SC codes (e.g., EKK0351A010SC) follow the pattern `EKK<NNNN><ABC>SC` where the numeric portion corresponds to specific service component tables.
