Railway Lines Video Data Acquisition System could not only acquire and compress railway lines video data in real time but also form index data that could be used for searching and positioning frame in latter playing video.

This paper proposes a neural network based incremental data indexing method.

In order to realize data storage and search, various biotechniques were touched on, such as selecting DNA carrier and receptor cell, creating data index, etc.

To solve the problem that MDS cannot effectively be used for incremental data index, the paper proposes a neural network based incremental data indexing approach.

An organization approach of massive terrain dataset based rectangular bintree and nonpointer data index is put forward for organization and management of massive terrain dataset.

There are many kinds of database index,such as B + -tree,AVL tree and SB-tree,which are built now,but through which we could not to search data on many keys.

After discussing the five theory models and six automatic indexing ways, the paper emphasizes on the mechanisms of the two essential objects: full text indexing and database indexing.

Design and Implement of Search Engine Index Database in a Internet;

In a full-text search system,the setting-up of the index database of full text is a systematic foundation.
