UACA: Unified Access Control Approach For Heterogeneous Database Based-on Service Data Object

Abstract: The requirement for data interchange, access, and retrieval from diverse databases. This is getting more crucial. However, retrieving this a heterogeneous database necessitates juggling many kinds of query languages, models, structure. goal project to create unified access control approach (UACA), which will be managed by service object (SDO) technologies based on an agent mechanism application business To control, applications must submitted through UACA. prevent direct link the security threats, isolates Application systems submit request identity authentication system using protocol system. Data are finally transmitted after authentication, gathering, transmission. investigation led creation client-middle layer, also in charge transformation optimization, ensure uniform database. It manages communication TCP/IP guarantee accuracy reliability connection. SDO offers strong adaptability compatibility.
