Abstract—The purpose of this paper is the discuss the working of a B+ Tree and understand why it is preferred over other types of structures in database systems.
Keywords—B+ Tree, B Tree , indexing.
I. INTRODUCTION
A database management system (DBMS) is a combination of programs that gives the ability for you to store, extract and modify information from a database. There exist many different types of database management systems, ranging from small systems that run on personal devices to large systems that run on mainframes.
Relational Database Management Systems (RDBMS) are the most popular database management systems used today. SQL (Sequential Query Language) is generally used to implement RDBMS. In RDMS, data is stored in tables and therefore the data is stored in rows and columns. RDBMS forms the base for all commercially used database management systems like Oracle, IBM DB2, MySQL etc.
II. Indexing
Data in a database are stored in ordered manner regardless of the structured being used. The data is stored in an ordered manner by using a primary key and unique identified value. This is known as indexing.
III. types data structures
Various types of data structures are used in a RDBMS. For example: Sequential Indexing, B Tree and B+ Tree.
A. Sequential
In this type of data structure, the records are ordered in a sequential manner. An index file keeps a track of the records by
Data objects can model relational data or advanced data types such as graphics, movies, and audio. Smalltalk, C++, Java, and others are objects used in object-oriented data. The object-relational is a combination of relational and object-oriented databases. Traditional and advanced data types can be used to construct database management systems. These systems can connect to a company’s website and update records as needed. Database Approach The main purpose of a database is data storage that can be stored and retrieved when needed. A popular common language called structured query language (SQL) is used to store and retrieve data in relational database. This language enables the systems to run a report or modify data or remove the data from the database. A database management system (DBMS) controls all aspects of a database, this is not limited to the creation, maintenance, and use of database. The DBMS ensures proper applications are able to access the database. An important purpose of a DBMS is to maintain the data definitions (data dictionary) for all the data elements in the database. It also enforces data integrity and security measures. Data Models Data models provide a contextual framework and graphical representation that aid in the definition of data elements. In a relational database, the data model lays the foundation for the database and identifies important entities,
A Relational Database Management System (RDBMS) is a type of database management system that stores data in the form of related tables. The system does not require many assumptions about how data is related t or how it is to be extracted from the database. The database can be viewed in several forms.
Database is defined as “the collection of information organized in such way that a computer program can quickly select the desired pieces of data.” (Haithcoat, n.d.). In today’s technological world most of the processes is automated where database plays an important role to manage the data across a system. A database can be considered as an electronic filing system. Traditional databases are organized by fields, records, and files. A field is a single element of information; a record is one complete set of elements; and a file is a collection of records. To manage these data across the database system, DBMS came into play and the basic role was to create the management of information across all the data. DBMS plays a critical and integral component of most successful GIS and used to store, manipulate and retrieve data from the database. Although the range of DBMS structures used in GIS includes inverted list, hierarchical, network and relation design.
A relational database is a database that consists of a collection of tables with columns showing entities, and rows showing data. This type of database uses a primary key and foreign key. The foreign key in another table will point to the primary key of a table, and this is how tables can relate to each other. This permits for one-to-one, one-to-many, and many-to-many relationship between the data. An advantage of relational databases includes the ease of adding or modifying new tables and entities without needing to change the structure of the database already in place. Relational database have many features, including indexing, setting data type, and setting validation tests, all these help to ensure data integrity.
The data structure represents the logical relationships between data elements. In addition the data also determines the organizational structure, access methods, and alternative processing assosiativitas level for information.
The database management system (DBMS) a group of programs used as interface between a database and application programs, or a database and the user. It is used to create and implement the right database system ensures that the database will support both business
Relational database contains data records that do not have a preset of relationships, permitting the user to define his or her relationship when accessing the data. Since users have much control over the data being accessed, relational databases can perform a variety of tasks. Such as defining the database; querying the database; adding, editing, and deleting data from the database; modifying the structure of the database; securing data from public access; communicating within the network; and exporting and importing data (Murthy, 2008).
A hierarchical data structure is implemented using multilinked lists that contain scalar items, vectors, and possibly, n-dimensional spaces.Stack is a conceptual model of a data structure that can be implemented as a vector or a linked
Since 1960 and beyond the need for an efficient data management and retrieval of data has always been an issue due to the growing need in business and academia. To resolve these issues a number of databases models have been created. Relational databases allow data storage, retrieval and manipulation using a standard Structured Query Language (SQL). Until now, relational databases were an optimal enterprise storage choice. However, with an increase in growth of stored and analyzed data, relational databases have displayed a variety of limitations. The limitations of scalability, storage and efficiency of queries due to the large volumes of data [1] [2].
Database system design can be extremely time-consuming as it takes sophisticated software to create and control it. The design process becomes less user-friendly as it takes a more extensive knowledge of how to use it. The standard of an excellent database is one, which is complete, integral, simple, understandable, flexible and
The idea of relational database was first introduced by E.F.Codd at IBM in 1970. It is a kind of computer database in which data is stored in Relations and is represented in the form of tables with rows and columns. Databases can vary in sizes, ranging from very small and simple to very large and complex ones. Database users can access the data practically in an unlimited number of ways. Relational databases help in finding the information in a quick and efficient manner that one is looking for.Today many popular databases use the model of relational database.
The application standard to use this kind of database is the structured query language (SQL).This statements are used for both communication with queries for information from a relational database this schema set of tables contain data built into predefined categories.

Database is any collection of data or information, that is specially organized for rapid search and retrieval by a computer. Databases are structured to facilitate the storage, retrieval, modification, and deletion of data in conjunction with various data-processing operations.
What is database management system? Database Management System is a database program. The DBMS manage incoming data, organize it, and provided ways for the data to be modified or extract by users or other programs. This cause, most database software comes with an Open Database Connectivity (ODBC) driver that allows the database to integrate with other databases. For example, common SQL statements such as SELECT and INSERT are translated from a program's proprietary syntax into a syntax other databases can understand. Some DBMS examples include PostgreSQL, MySQL, SQL Server, Microsoft Access, Oracle, FileMaker, RDBMS, dBASE, Clipper, and FoxPro. It is a software system that uses a standard method of retrieving, and running queries on data.
