In this article, we will review stored procedures and functions needed to maintain a tree structure in a database. In this case, we have used Microsoft SQL Server 2008 as our DBMS. We will see how to List, Add, Edit, Delete, Move and Copy nodes in the tree with SQL and how to mai...
In addition, the querying process in image/video DBMSs is expected to be iterative with progressively more refined queries being issued during the later stages. Thus the indexing structure should be able to efficiently support both vague queries ( retrieving a large number of approximate matches) ...
The advent of MMDB requires a reconsideration of data structures and algorithms of traditional DBMS. The index structure is one of the most important aspects that need be redesigned since it can affect the overall system performance heavily. Even though the T-tree index, which was proposed for ...

B+ Tree Structure (2) Each path from the ROOT to any leaf has the same length. Length is the number of nodes in a path. Supports equality and range-searches efficiently. B+ Tree Equality Search Search begins at root, and key comparisons direct it to a leaf. ...

However, the B -tree structure, which is a representative index scheme of current relational DBMSs, produces excessive I10 operations in random order when its node structures are updated. Therefore, the conventional B+-tree structure is unfavorable for use in SSDs. In this paper, we propose ...
MB+-Tree: An Index Structure for Content-Based Retrieval Though standard database management systems(DBMSs) dealing mainly with alphanumeric or spatial data have reached a high level of maturity, the techniques employed there cannot be effectively applied to the management of other multimedia ... ...
Decision tree has a tree structure built top-down that has a root node, branches, and leaf nodes. In some applications of Oracle Machine Learning for SQL, the reason for predicting one outcome or another may not be important in evaluating the overall quality of a model. In others, the ...
