After a long period of research, development, test and trial, relational database management systems are at last being marketed in force. The feedback from early installations of these systems is overwhelmingly positive. The most frequent comment by users is that productivity has been increased by a significant factor (from 5 to 20 times what it was using previous approaches). Another comment is that, in many cases, end users can now handle their own problems by direct use of the system instead of using application programmers as mediators between them and the system. As the reputation of relational systems for ease of use and enhanced productivity has grown, there has been a strong temptation for vendors of other approaches to exploit the label "relational" somewhat indiscriminately. In some cases the label is being misapplied to a whole data system; in others it is being misapplied to an interface. It is therefore worth developing criteria which database management systems (DBMSs) should have in order to be called "relational". The Relational Task Group (RTG) of the American National Standards Institute (ANSI) undertook such an effort by developing a characterization of RDBMSs and analyzing fourteen DBMSs per this characterization. The result of this work is presented in this book. The conclusions of the RTG are in agreement with my view that a DBMS should not be called "relational" unless it satisfies at least the following conditions: 1. All information in the database is represented as values in tables.

As huge amount of data is increasing day by day and it cannot be managed easily by relational databases because of low scalability provided by the relational databases. The storage technology is still not capable enough for the performance and scalability that is needed to store data but after 2005 NoSQL databases have come in existence and start solving the problems that relational databases were facing before. NoSQL is a type of such databases that come under non-relational databases. There are four types of NoSQL databases and these types are { Key Value Store}, {Column Store} ,{ Document databases},{ Graph databases}, each one of these databases has different features. Now , the question arise is whether non-relational databases are the right choice to continue or to stay with the old relational databases for applications and web development and from where NoSQL came from, how they are represented and what are the types of relational and non-relational databases, these all questions are going to be explained in this thesis. The objectives of this thesis are to show that the why need of NoSQL databases became necessary with the time, second objective is to show the types and representation of various types of relational and non-relational databases, third objective is to focus about MongoDB which is a type of Document Databases under the category of NoSQL database that is a non-relational database and comparison of MySQL that is a relational database with MongoDB by how to represent these two databases and how to write answers for same query in MySQL and MongoDB, then a comparison analysis by calculating the time of selection, updating and deleting between MongoDB and MySQL .

Relational Databases explores the major advances in relational databases and provides a balanced analysis of the state of the art in relational databases. Topics covered include capture and analysis of data placement requirements; distributed relational database systems; data dependency manipulation in database schemata; and relational database support for computer graphics and computer aided design. This book is divided into three sections and begins with an overview of the theory and practice of distributed systems, using the example of INGRES from Relational Technology as illustration. The following chapters focus on whether relational and relational-like systems actually meet business needs; IBM's Structured Query Language/Data System (SQL/DS); tools for database design and programming; and Secondary Access Methods and the problem of secondary index selection. A number of quantitative models for assessing the performance of physical databases are also described. This text concludes by assessing some of the most conspicuous trends in relational database research and development. This monograph will be of interest to database designers.

This textbook offers a comprehensive introduction to relational (SQL) and non-relational (NoSQL) databases. The authors thoroughly review the current state of database tools and techniques and examine upcoming innovations. In the first five chapters, the authors analyze in detail the management, modeling, languages, security, and architecture of relational databases, graph databases, and document databases. Moreover, an overview of other SQL- and NoSQL-based database approaches is provided. In addition to classic concepts such as the entity and relationship model and its mapping in SQL database schemas, query languages or transaction management, other aspects for NoSQL databases such as non-relational data models, document and graph query languages (MQL, Cypher), the Map/Reduce procedure, distribution options (sharding, replication) or the CAP theorem (Consistency, Availability, Partition Tolerance) are explained. This 2nd English edition offers a new in-depth introduction to document databases with a method for modeling document structures, an overview of the document-oriented MongoDB query language MQL as well as security and architecture aspects. The topic of database security is newly introduced as a separate chapter and analyzed in detail with regard to data protection, integrity, and transactions. Texts on data management, database programming, and data warehousing and data lakes have been updated. In addition, the book now explains the concepts of JSON, JSON schema, BSON, index-free neighborhood, cloud databases, search engines and time series databases. The book includes more than 100 tables, examples and illustrations, and each chapter offers a list of resources for further reading. It conveys an in-depth comparison of relational and non-relational approaches and shows how to undertake development for big data applications. This way, it benefits students and practitioners working across the broad field of data science and applied information technology.

Structure Query Language (SQL) and Query By Example (QBE) are the most widely used query languages for Relational Database Management Systems (RDBMS's). However, both of them have problems concerning ease-of-use issues, especially in expressing universal quantification, specifying complex nested queries, and flexibility and consistency in specifying queries with respect to data retrieval. To alleviate these problems, a new query language called 'DataFlow Query Language' (DFQL) was proposed. This thesis investigates the relative strengths and weaknesses of these three languages. We divide queries into four categories: single-value, set-value, statistical result, and set-count value. In each category, a representative set of queries from each language is specified and compared. Some of the queries specified are logical extensions of the other (already defined) queries, which are used to analyze the query languages' flexibility and consistency in formulating logically related queries. We perform a simple experiment of asking NPS CS students to write a small set of queries in all three languages. Based on the analysis, we conclude that DFQL eliminates the problems of SQL and QBE mentioned above. The relative strengths of DFQL comes mainly from its strict adherence to relational algebra and dataflow-based visuality.
