Qualitative model to enhance quality of metadata for data warehouse

A metadata quality directly impact on the decision making. Therefore, the metadata is enhanced with semantics to improve quality of metadata but no formal representation is laid down. Here in this work, the formal representation of metadata is proposed to enhance the quality of information required for decision making. Therefore, in this paper three formal models are defined to properly manage metadata with different types of operation and to provide qualitative information to user. First is to define the metadata. Second is to describe metadata development process. Third model is used to formally describe the complete process of metadata management. All three models are used to properly representation and management of metadata. © 2018, Bharati Vidyapeeth's Institute of Computer Applications and Management.
