* Detailed Description of Fees

  • 1. Difference in billing method: BA method is billed per application server. DA method is billed per DB server vCPU.
  • 2. Difference of encryption method:
    • DA method includes query editing by inserting an encryption/decryption API into the DB server to perform the final encryption/decryption.
    • The BA method includes source editing by inserting the API into the application server terminal to send encrypted/decrypted data to the DB server.
  • 3. Difference of restrictions in client environment:
    • The DA method operates as partially dependent on DBMS and requires query editing.
    • The BA method, which operates independently with DBMS, may have limitations depending on the language, and requires source editing.
  • 4. An environment that cannot be accessed by DA or Cloud DB and No SQL DB may be proposed as BA (API).
Component Name
MeaningEncryption MethodComponent DescriptionBilling Policy
APIa. An API method that performs encryption in application without any effect on DBMS.
b. BA-JPF is an API optimized for the Java Framework Platform.
c. If many clients share 1 DBMS, encryption is possible with the BA method only.
d. Source editing of the client web server is required (by developer).
  • Monthly billing of the license, cost based on 1 application server unit.
  • The installation cost is applied per application server.
  • Quotes can vary depending on the number of application servers.
DADBMS ApplicationDB[MS] APIa. Method of encryption by providing lightweight functions using DB[MS] API method.
b. User defined functions are provided within the DBMS.
c. Method of editing all queries that include the column subject to encryption.
(A part of editing development may need to be performed by the customer.)
  • Monthly billing of license cost based on 1 DB server unit (default 4 vCPUs)
  • Installation cost is applied per DB server.
