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 byShow MoreRelatedRelational Database Management System ( Rdbms )996 Words   |  4 Pagesevaluation of how Relational Database Management System (RDBMS) can be applied to improve organization and business effectiveness.

However, these databases are facing several challenges with the requirements of many organizations like high scalability and availability. They cannot deal with huge amount of data and requests efficiently. As a result, famous organizations such as Google and Amazon shift from RDBMS to NoSQL databases. NoSQL databases have several features that overcome issues.

Ans) The things that we consider before recommending SQL, NoSQL or BigData are: Scalability: NoSQL databases are designed to expand transparently and horizontally to take advantage of new nodes, and designed with low-cost hardware. SQL have problems in Scalability. Data Capability: RDBMS are intolerable for large data volumes. NoSQL distributed databases, allow data toRead MoreDatabase Analysis : Database Management System Essay1337 Words   |  6 PagesDatabases are fundamentally containers for data. When data for any organization needs to be stored, databases can be used. For example, let’s say a public library stores books, we could say that the library is a database of books. But specifically, databases are computer structures that save, organize, safeguard and produce and/or deliver data. A database platform is essentially a database management system (DBMS) which is a computer software application that interacts with the user, other applicationsRead MoreBig Data And Its Opportunities1514 Words   |  7 Pagesissue called Information Explosion. Information Explosion is defined as the rate of growth of volume of data. Initially Scalable database systems (DBMS) were used to recover structured data from many sources. The most famous DBMS type is RDBM S (Relational Database Management Systems). In RDBMS data is stored in tables. As the data increases, time taken to query it from RDBMS becomes large and the cost of querying also increases. They have an exponential relationship. When data increases, time to queryRead MoreMicrosoft Sql Database Management System872 Words   |  4 PagesMethodology Microsoft SQL Database Administrator Database plays a major role in any organization.
