Abstract
A Spatial Database is a database that offers spatial data types, a query language with spatial predicates, spatial indexing techniques, and efficient processing of spatial queries. All these fields have attracted the focus of researchers over the past 25 years. The main reason for studying spatial databases has been applications that emerged during this period, such as Geographical Information Systems, Computer-Aided Design, Very Large Scale Integration design, Multimedia Information Systems, and so forth. In parallel, the field of temporal databases, databases that deal with the management of timevarying data, attracted the research community since numerous database applications (i.e., Banking, Personnel Management, Transportation Scheduling) involve the notion of time.

Towards the Integration of Trajectory Information Sources for Semantic Conflicts Detection Purpose: A Trajectory Ontology Based Approach
Trajectory is the record of a time-varying spatial phenomenon. Trajectory consists in the description of the movement of some moving objects at specific moment’s time. In reality, trajectory has to be built from a set of sample points which correspond to moving object positions.

Tragedy and Trajectories of Human Trafficking: A Biblical Perspective for Sub-Saharan Africa
Trajectory comes from the Latin trajectoria , which means “throw across.” The prefix tra- is short for trans-, which means “across” and the ject comes from jacere , which means “throw” and is also the root of the word jet. If you wanted to describe the path of a jet through the sky, you could refer to the jet's trajectory. However, within the context of this research, it is used to mean a connected series of events or actions or developments and/or the increasing continuation of such occurrence(s).
