The primary data structures supported by Redis that are stored in the server's RAM are Strings, Hashes, Lists, Sets, and Sorted Sets. This makes reading and writing operations exceptionally fast.

Redis is an open source that is BSD licensed. BSD stands for Berkeley Source Distribution which is used for the distribution of many freeware, Shareware, and open-source software. It is a low-restriction and requirement license type.

Some disadvantages of using Redis are that it has no persistence where the data is only available while the server is running and there is no query language. Redis doesn't natively support secondary indexes and that limits data access and flexibility.

Support for transactions and public/subscribe messaging are some attractive features Redis has to be used as a database. Due to the in-memory storage, Redis also provides fast access to data and high performance.

Redis is not a document database, it is an open-source, in-memory data structure store, used as a database, cache, and message broker. It is often used for caching web pages and reducing the load on servers.

Every document field is indexed using primary and secondary in MongoDB. This reduces the time to search for data in the database and is considered one of the top features of MongoDB because it cuts down the time spent finding answers to queries.

NoSQL databases offer easy data distribution, simplified data models, and automated repair. Due to these advantages, NoSQL databases result in less expenses and are easier to maintain.

MongoDB is user-friendly because it is free of schema problems, is possible to store data in the NoSQL database without the need to use a predefined schema, which means that you can alter the model of data and format w/o affection applications.

Did you know that NoSQL stands for "not only SQL"??? Not "No SQL" that sounds like there's no SQL involved in the database. Yeah, I was pretty taken aback.

#databases @KhouryCollege

MongoDB is that its name is derived from the word "humongous," which roughly means “gigantic” reflecting its capability to handle large volumes of data.

Looking for an open-source, NoSQL database management system that is designed for scalability, flexibility, and performance? Try MongoDB! MongoDB uses a document-oriented data model, which stores data in flexible, JSON-like documents.

Bulk loading involves efficiently inserting a large number of entries into an index. One method is to create a temporary file with index entries, sort it based on the search key, and then insert the sorted entries into the index.

Apparently, JDBC was an abbreviation for Java Database Connectivity but the full form is no longer used. JDBC is a standard that defies an application program interface (API) that Java programs can use to connect to database servers.

Materialized views are views kept up-to-date to allow view relations to be stored. The process of keeping the materialized view up-to-date is called materialized view maintenance.

There are two ways to end a transaction in SQL statements. One is commit work which commits the current transaction that updates the performed are permanent in the database. When this happens a new transaction is automatically started.

In SQL, a combination of the left and right outer-join types is called the full outer join. It is the union of a left outer join and the corresponding right outer join.
