A database is a collection of information or data which are organized in such a way that it can be easily accessed, managed and retrieved. Database is abbreviated ad DB. Different definitions of database. “a usually large collection of data organized especially for rapid search and retrieval (as by a computer) an online database” (merriam-webster) “a comprehensive collection of related data organized for convenient access, generally in a computer.” (dictionary) A database is an organized collection of data. (Wikipedia) What is data? It is used as both singular and plural form. It can be a quantity, symbol or character on which operations are performed. Data is information which are converted into digital form. Growth of Database Database was evolved in 1960's started with the hierarchical database. Relational database was invented by EF Codd in 1970s while object oriented database was invented in 1980s. In 1990s object oriented database rose with the growth of object oriented programming languages. Nowadays, databases with SQL and NoSQL are popular. Elements of Database Database elements are fields, rows, columns, tables. All these are building blocks of database.

  • The Neo Database – a Technology Introduction (2006­11­23)
    The Neo Database ± A Technology Introduction (2006-11-23) The Neo Database This document is an introduction to the Neo database, a next-generation database which we believe addresses some of the shortcomings of the data management systems on the market today. The target audience is a technologically inclined person with a background in software development. This document gives an overview of what Neo does and the benefits and drawbacks of using Neo in your application development. It will also try to give a glimpse of how Neo works and how developing with Neo is different from developing with a relational database. In a nut-shell, Neo is a robust, scalable, high-performance and embedded persistence engine for efficient management of semi-structured and network-oriented data. That©s a lot of buzzwords! Let©s have a closer look: • Neo is a database designed for network-oriented data. This is data that is ordered in complex networks or deep trees. Where the relational model is based on tables, columns and rows, Neo©s primitives are nodes, relationships and properties. Together, these form a large network of information that we call a node space. • Additionally, Neo shines at handling semi-structured data. Semi-structured data is a research term that is quickly gaining ground outside of academia. Simply put, semi-structured data typically has few mandatory but many optional attributes. As a consequence, it usually has a very dynamic structure, sometimes to the point where it varies even between every single element. Data with that degree of variance is difficult to fit in a relational database schema but can be easily represented in the Neo model.

  • Comparative Analysis of Legacy Database Systems P a G E | 1
    Comparative Analysis of Legacy Database Systems P a g e | 1 Legacy Database Systems What is a Database? Data is collection of facts and figures which can be processed to produce information whereas a database is the collection of correlated data. For Example, Name of a student, age, class and the subjects can be counted as data for recording purposes. And the names, telephone numbers, and addresses of the people which have been recorded in an indexed address book or stored on a portable hard drive using software such as Microsoft Access or Excel. This collection of related data having an absolute meaning is a database. Database Managеmеnt Systеm: Database Management System or DBMS refers to the mechanism of storing and reclaiming users’ data with uttermost efficiency along with the security attributes. This type of system allows its users to create their own databases which are apropos to the nature of work they desire. Such database systems are highly customizable and proffers bunch of options. The DBMS is therefore such a general purpose system software that facilitates the processes of defining, constructing, manipulating, and sharing of the databases among diverse users and applications. History of Database: The 1960s was the beginning of database management systems (DBMS) when vendors began marketing computerized logistics technologies for manufacturing and wider laboratory use. Intrusion detection system or IDS was one such archaic network databases that was developed by the computer division known as General Electric. Another database was IMS or Information Management System developed by IBM. This was a navigational database. It used the navigational approach in which the navigation method was used as an approach to find information about different various data.

    Vol-6 Issue-2 2020 IJARIIE-ISSN(O)-2395-4396 OVERVIEW OF DATABASE EVOLUTION AND ELEVATION Dr. A. R. Revathi1, R. Bhuvaneswaran2, K. Mohamed Arshath2, U. Hari Prakash2, M. Loga Aravinth2 1Associate Professor, Department of IT, SRM Valliammai Engineering College, Tamil Nadu, India. 2 Student, Department of IT, SRM Valliammai Engineering College, Tamil Nadu, India. ABSTRACT “INFORMATION IS THE OIL OF THE 21st CENTURY, AND ANALYTICS IS THE COMBUSTION ENGINE. “ -PETER SONDERGAARD Nowadays, databases and managing databases is essential because as most of the applications deals with an integral part of user related data. For an organization database must be very crucial. As it deals with user current or stored records either structurally or unstructurally in order to retrieve the required records. Thus the need for a database is to manipulate data, store and identify data and finally to organize data in two ways namely schema based and schema less. This paper illustrates the need of database technology and its properties along with a transition path towards the track to origin of database with advantages and disadvantages, development and step forward to view the upcoming database with New Structured Query Language. Keyword: Database, Structured and unstructured data, Schema, New Structured Query Language. 1. INTRODUCTION “A database is a self-describing collection of integrated records. A record is a representation of some physical or conceptual object. A database is self-describing in that it contains a description of its own structure. This description is called metadata - data about the data. The database is integrated in that it includes the relationships among data items, as well as including the data items themselves” [1].
