We designed a new Data Warehouse end to end and I took part in thisproject as an Architect. We still continue to develop this new DWH using inhouseFinance Logical Data Modeling. We applied hybrid logical model:Inmon’s 3NF model for Foundation Layer, Kimbal’s model for Conformedand Datamart Layer. I worked as Scrum Master in my agile team. We buildthe data warehouse on Oracle Exadata platform using ODI for ETLdevelopment. I designed all Etl mapping naming conventions, tablestructures (partition, sequence, index), Knowledge Modules (codetemplate) for all table types (SurrogateKey, Lookup, Master, Relation,History-Type2, Datamart). I share all my knowledge with my colleague at thebeginning of the project. I support all my co-worker at my agile team and Iwas scrum master for 1 year. I joined Retirement committee due to tableretirement and db size shrink. I’m leading DataOps committee toidentify and automate all dataline life cycle. I guide all my colleagues toa solution when there is a problem. I control data quality, etlmaintenance, daily batches performance monitoring.
