HBASE Vs. RDBMS Top Differences You can Unlock Now

Image
HBASE in the Big data context has a lot of benefits over RDBMS. The listed differences below make you understandable why HBASE is popular in Hadoop (or Bigdata) platform. Let us check one by one quickly. HBASE Vs. RDBMS Differences Random Accessing HBase handles a large amount of data that is store in a distributed manner in the column-oriented format while RDBMS is systematic storage of a database that cannot support a random manner for accessing the database. Database Rules RDBMS strictly follow Codd's 12 rules with fixed schemas and row-oriented manner of database and also follow ACID properties. HBase follows BASE properties and implement complex queries. Secondary indexes, complex inner and outer joins, count, sum, sort, group, and data of page and table can easily be accessible by RDBMS. Storage From small to medium storage application there is the use of RDBMS that provide the solution with MySQL and PostgreSQL whose size increase with concurrency and performance.  Codd'

6 Top Solidity Interview Questions

Solidity is the prime language to write the logic for smart contracts in the Ethereum blockchain. These are selected interview questions refresh before you take an interview. Solidity Interview Questions on Solidity 1. What is Solidity? A) Solidity is the main language that you can use to write programs in Blockchain, such as smart contracts. 2. Where the Solidity programs run in Ethereum? A). Those will run in EVM. You can also call it an Ethereum Virtual Machine. 3. What kind of logic a Smart Contract can contain? A contract in the sense of Solidity is a collection of code (its functions) and data (its state) that resides at a specific address on the Ethereum blockchain 4). Can the source code of smart contracts accessible to the outside world?  A). No, it is not possible to access the source code to the network. Also, there is limited access to one smart contract logic to the other smart contract logic. Eve, file systems, and other processes cannot access the source
