Improvements in NoSQL databases over last decade

NoSQL databases, also known as Non-Relational databases, have seen a dramatic improvement over the past few years. With the exponential growth of big data, the demand for flexible, scalable and high-performance data storage solutions has increased. This has driven the evolution of NoSQL databases, and as a result, they have become more sophisticated and feature-rich. In this article, we will explore some of the key improvements in NoSQL databases and how they have become a more viable option for organizations of all sizes.

Transactional Support

One of the major improvements in NoSQL databases is the increased support for transactions. Transactions are essential for ensuring data consistency and integrity in applications. In the past, NoSQL databases were known for their lack of transactional support, but now many NoSQL databases provide transactional support. This makes NoSQL databases a better option for use cases that require strong consistency, such as financial applications.

For example, MongoDB is a NoSQL database that supports transactions. With the introduction of multi-document transactions in MongoDB 4.0, developers can now ensure that their data is consistent even in the face of failures or errors. This makes MongoDB a better choice for use cases that require transactional support, such as e-commerce applications.

Data Modeling and Query Capabilities

Another improvement in NoSQL databases is the increased focus on data modeling and query capabilities. In the past, NoSQL databases were criticized for their lack of query capabilities, but now many NoSQL databases support sophisticated query languages and offer improved data modeling capabilities. This makes it easier for developers to manage and access data.

For example, Apache Cassandra is a NoSQL database that provides a flexible data model and sophisticated query capabilities. With Cassandra, developers can define data models that match the needs of their applications, and the database supports a rich set of query capabilities, including secondary indexes, materialized views, and more.

Performance

The performance of NoSQL databases has also improved significantly. With advancements in hardware and software, NoSQL databases can now handle big data and deliver fast, scalable performance. In addition, many NoSQL databases have added indexing and caching capabilities to improve query performance.

For example, Redis is a NoSQL database that is known for its fast performance. Redis uses an in-memory data store, which allows it to deliver fast performance even with large datasets. In addition, Redis supports a variety of data structures, including lists, sets, and hashes, making it a flexible solution for a wide range of use cases.

Flexibility in Deployment Options

NoSQL databases have also become more flexible in their deployment options. Many NoSQL databases can now be deployed on-premises, in the cloud or as a hybrid solution, providing organizations with the flexibility to choose the deployment model that best meets their needs.

For example, Amazon DynamoDB is a NoSQL database that can be deployed in the cloud. DynamoDB provides a scalable, highly available data store that can be used for a wide range of use cases. With DynamoDB, organizations can take advantage of the scalability and performance of the cloud, and pay only for the resources they use.

User-Friendliness

Finally, NoSQL databases have become more accessible and user-friendly. With the increased use of NoSQL databases, many vendors have added features and functionalities that make it easier for developers to use NoSQL databases and integrate them with other systems.

For example, CouchDB is a NoSQL database that is known for its user-friendliness. CouchDB provides a simple REST API that makes it easy for developers to access data, and the database supports a variety of programming languages, including Java, Python, and Ruby

भटकता जब मैं अपना पथ भूल जाता लगाकर मैं गोता, वापस मुझको लाने वाला काश ऐसा कोई तो होता। गिरकर, भटककर, खाकर चोट जब मैं मन ही मन रोता, मेरे दुखों को समझने वाला काश ऐसा कोई तो होता। सन्नाटे के धुंध में जब चुप चुप अकेले मैं सोता, मुझसे बातें करने वाला काश ऐसा कोई तो होता। अनगिनत जिम्मेदारियां अपनी होकर असहाय जब मैं ढोता, मुझको सहारा देने वाला काश ऐसा कोई तो होता। जीवन के संघर्षों से लड़कर जब मैं अपना मनोबल खोता, साहस मुझे बंधाने वाला काश ऐसा कोई तो होता। खाकर अपने पीठ पे खंजर जब मैं अपने जख्मों को धोता, मरहम मुझको करने वाला काश ऐसा कोई तो होता। -- शशिकांत * उपरोक्त पंक्तियाँ मेरी पुस्तक " आ तमाशा तू भी देख " का अंश हैं।

Coin Flipping Puzzle: Interview Question

Golu has 100 identical coins (with head side and tail side) which he wants to donate to someone. There are many people who are aiming to get this collection of 100 coins. So Golu created a puzzle using all 100 coins and declared that the one who will solve his puzzle will get all the coins. You desperately need money so solving the puzzle is only option you have. The Problem goes like this: All 100 coins are laying flat on a table. 80 of them are heads up and remaining 20 are tails up. You can’t feel, see or in any other way find out which side is up. Split the coins into two piles(sets) such that there are the same number of tails in each pile. [Baby Hint]: If number of coins in first pile is n then other pile will have 100-n coins. First try yourself before peeking into the solution below.

JSON vs YAML

JSON JSON(JavaScript Object Notation) is a human-readable data exchange format. JSON is built on two structures: A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array. An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence. JSON's basic data types are: Number : a signed decimal number that may contain a fractional part and may use exponential E notation, but cannot include non-numbers such as NaN. The format makes no distinction between integer and floating-point. JavaScript uses a double-precision floating-point format for all its numeric values, but other languages implementing JSON may encode numbers differently. String : a sequence of zero or more Unicode characters. Strings are delimited with double-quotation marks and support a backslash escaping syntax. Boolean : either of the values true or false Arra

[Fixed] Alexa can count only from 1 to 10

Note : At the time of writing this post, Alexa had this issue which has been resolved. Alexa can now count flawlessley even in reverse. Alexa is the smart virtual assistance by Amazon. It is beating google now and Siri on non-screen devices. Alexa is hailed for its intelligence but it seems that the Alexa knows to count only from 1 to 10. By 1 to 10, I mean exactly from 1 to 10; neither more nor less. Even asking Alexa to count from 1 to 5 or 3 to 10 or 3 to 5 results in an apology from Alexa. Watch the above video to see for yourself.
