Temporal database has been one of the special kinds in the field of database. According to the concept of time, stamping various models has emerged and temporal models namely; McKenzie, BenZvi’s, and non-temporal models namely; Colby, Deshpande and Larson’s model has grabbed unique attention towards in this area of temporal database. Reliable and Enhanced stratum middleware management capabilities enable the temporal queries for ease in transactions. Richness in point based and maximum timestamp approaches provide high indexing mechanisms, which make efficient storage of data in tree structure format. The proposed prototype model uses Temporal Relational Algebra and TSQL2 declarative language, which display the past, present and future related data. The inclusion of T4SQL instead of TSQL2, Temporal Multi-Secure Database and spatio-temporal database model can make this model stronger than present and make it work more efficiently.
