Recommended: List and describe the different types of databases

In the world of database technology, there are two main types of databases: SQL and NoSQL—or, relational databases and non-relational databases. The difference speaks to how they’re built, the type of information they store, and how they store it. Relational databases are structured, like phone books that store phone numbers and addresses.
Non-relational databases [7] are distributed and are document-oriented just like file folders hold everything from a person’s address and phone number to their tweets online surfing preferences, in the similar manner non-relational databases keep tracks of all documents.

First, let’s take a look at one of the main features that separates these two systems: the …show more content…

In an SQL database like MySQL, or Oracle, it executes queries, retrieves or updates data, and even deletes or creates new records. SQL is a lightweight language that is declarative and does a lot of heavy lifting for the relational database, thus it may act like a server side script but only database version of it.
POPULAR SQL DATABASES AND RDBMS’S

Enter non-relational databases, which provide much greater flexibility than their traditional counterparts. Suppose non-relational databases as file folders, arranging correlated information of all kinds. Every file of WordPress could carry data for a blog post like social likes, images, text, metrics, link and much more by using NoSQL database.
Sensor data, social networking, personal settings, photos, information based on location, online activity, metric usage, etc., can be included in unstructured data from the web. The attempt to store, process, and analyze this entire unstructured data became the cause of development of schema-less alternatives to SQL. Considered together, these alternatives are referred to as NoSQL, denoting “not only SQL”. Whereas, the term NoSQL surrounds a large range of alternatives to relational databases, and the feature that they have in common is that they enable you to treat data more

Then again, a record framework is a more unstructured information store for putting away discretionary, presumably disconnected information. The record framework is more broad, and databases are based on top of the general information stockpiling administrations gave by document frameworks. There are additionally contrasts in the normal level of administration gave by document frameworks and databases. While databases must act naturally reliable at any moment in time (consider banks following cash!), give confined exchanges and sturdy composes, a document framework gives much looser

Moreover, DBAs should know the database management systems (DBMS) that include the knowledge of Oracle, IBM DB2, and Microsoft SQL server (“Database Administrator,” 2010). Oracle is one of the most important platforms that DBA must know and have experience with.

With the modern era of databases not everyone sees the advantages of using relational databases. NoSQL, was first developed in the twenty first century (MongoDB, para 19) to address the issues that the SQL language could not handle. NoSQL cannot handle pure relational database models, it can use any of five different kinds of models, including relational to solve problems. With the variety of models, designers are wondering if there is a future for the strictly relational language SQL, and it’s other disadvantages compared to that of NoSQL.

    In the past, most of the databases were centralized, protected, and kept in a one location using a complicated database system known as centralized database. Nowadays, with the new technology of personal computers and cell phones, a new sort of database has appeared, and it seems that majority of people are pleasant with it, even if their private data is split everywhere. Many enterprises had changed their databases from the centralized databases, into the distributed database system, since it meets the demand of accessing and processing the data in the organization. Distributed database technology is considered as one of the most remarkable developments in this century (Ozsu, 1991; Rahimi & Haug, 2010; Cain, 2012). Distributed databases are basically a collection of databases that are divided on multiple computers which are connected logically but located in different physical locations, and each site manages its own local data. In contrast, centralized database is a database that is located in a one location and it is considered as a big single database (Connolly & Begg, 2010).
