Due to rapid increase in the use of location based services applications, large amount of location data of moving object is recorded. Because of that efficient indexing techniques are required to manage these large amounts of trajectory data. All index structures are focused on either indexing past, current and future locations. Every indexing structure or techniques discussed in this paper will make simpler indexing or it will increase the overall query processing performance. . Goals:. Store large files. Support multiple search keys. Support efficient insert, delete, and range queries. 2. Files and Indexing. Entry sequenced file. : Order records by time of insertion.. Search with sequential search.
