​“Similar to the well-known knowledge management system Wikipedia, OOCL has its own internal wiki for knowledge sharing. It is a important platform for hosting and sharing information and knowledge about OOCL and our industry. During the summer, what I have completed is the implementation of online backup of OOCL wiki database, which can improve the data integrity and avoid data loss. Initially, I have zero knowledge of database administration, but finally I succeed. It is a kind of miracles for me and I have really learnt a lot! Lots of thanks to my colleagues who teach me, guide me and help me.” Edmund Mui, student of Computer Science in CUHK.
