what is the difference between transactional and relational databases?

Relational - it means data is organized in tables and there are several mechanisms recognized like primary key, foreign key, uniqueness, data normalization. ... Transactional database is database able to manipulate data within transactions.

NoSQL databases have a dynamic schema for document type or unstructured data whereas SQL Databases have a well-designed pre-defined schema. SQL databases are vertically scalable whereas NoSQL databases are horizontally scalable. You can scale the SQL databases by expanding the strength of its hardware.

The basic difference between E-R Model and Relational Model is that E-R model specifically deals with entities and their relations. On the other hand, the Relational Model deals with Tables and relation between the data of those tables. An E-R Model describes the data with entity set, relationship set and attributes.

The main difference between relational and hierarchical database is that the relational database follows the relational model and stores data in tables while the hierarchical database follows hierarchical model and stores data in tree-like structure. A database is a collection of related data.

Relational databases are the most common database systems. They include databases like SQL Server, Oracle Database, Sybase, Informix, and MySQL. The relational database management systems (RDMS) feature much better performance for managing data over desktop database programs.

Relational databases are harder to scale(*) because they have features NoSQLs do not have, and these very features actually are harder to scale. First of all, from RDBMS you expect constraints and ACID transactions which are not present in NoSQL.

The basic difference between Relational Algebra and Relational Calculus is that Relational Algebra is a Procedural language whereas, the Relational Calculus is a Non-Procedural, instead it is a Declarative language. ... Relational Algebra specifies the sequence in which operations have to be performed in the query.

The key difference is that RDBMS (relational database management system) applications store data in a tabular form, while DBMS applications store data as files. ... The relationships between these data values will be stored in the form of a table as well. Every value stored in the relational database is accessible.

A transaction history differs from a bank statement in that it is a record of all transactions for a set period. Unlike a bank statement, a transaction history allows you to choose the period you want reflected. ... Transaction histories also tend to be more recent.
