Are you curious to know why the Oracle database is the most preferred and popular in the industry? Let us check what makes Oracle so popular and the features it offers. The database is a structural system designed to store data in an organized manner.
By definition, data in simple terms is any information that you use and can store to be used for later perusal. A Database stores information very similar to a table drawn on a paper, with columns and rows to store data.
There are way too many kinds of databases available in the market today,
Oracle DB is the known most popular database and known to have more than 50% of the market share in the field of databases. It is now available on the cloud as well as on-premise platforms. The most recent version of oracle database is 19c was released in the first half of 2019. Oracle database is an enterprise database, whereas MySQL is an open-source database.
Evolution of data storage
The concept of data storage for various purposes is not a new concept at all. The history goes way back in time. Prehistoric man-made natural written tiles of clay or leaves can be called the very first data storage. History shows many kinds of papers and wooden logs preserved to save the information stored during ancient times.
Punch cards and punch tapes were very famous around 1700-1900s.
Then the evolution began and came to the era of cassettes, magnetic storage and floppy discs.
The hard memory drives, the compact discs and DVDs rocked the late 1900s until the tiny pen also called flash drives came into existence. This evolution has never stopped, the cloud storage became a big buzz in early 2014-2015s, and now the development instead has reached up to the sky, and the future of data storage is considered to be the world’s most micro-objects including human DNAs, bacterias or carbon crystals such as sand grains.
DBMS: Database Management System is a concept introduced to organize and manage multiple datasets and store data in a more meaningful way. A real-life example can be a file cabinet in an office where each drawer has a significant category assigned, and each file relevant to each type is stored in that particular drawer. In a similar way, a software that enables to store, modify, manipulate and extract data along with data related to the data from the database is called DBMS.
Data security and access authorization are also prime duties of a DBMS system.
RDBMS: a relational database management system is simply a DBMS based on relational models.
DDL – Data Definition Language. It stores data related to the model and the tables created in the relational database. Data entry governance is taken care of by DDL and RDBMS enforces the governance rules.
DML – Data Manipulation Language. It allows the user to Insert, Update or Delete the data from tables along with many other kinds of data manipulation activities.
Data extraction – extracting data from a database. Complex queries with multiple joins tend to slow down the query performance.
In addition to these RDMS administrates and defines the User accounts along with their user access roles.
In the late 1990s, the oracle software written in assembly language was published. Around 1982-83 the oracle version 3.0 and ORacle corporation was launched. Since then, the database has been going through drastic upgrades and changes to deliver high-end services to customers and organizations. A straightforward form of data is represented in the below format, where there are multiple dataset tables are stored, organized based on categories along with the data related to these data tables, and when a query is sent to a database based on indexes a search is executed to locate and retrieve the required output. SQL is an ANSI standard language and the most commonly .used language for querying
Features Of Oracle Database:
- ACID compliance is the main feature as it ensures security and integrity, which is of prime importance to companies.
- Oracle DB uses logical data structures to store data; hence the physical location of the data can be easily located.
- It is easy to network and interact with other services and databases with Oracle DB in place using its networking stack.
- It is a cross-platform service; hence it supports multiple hardware and various operating systems.
- Oracle’s data dictionary enables easy administration and maintenance.
- Oracle’s partitioning and memory caching are two main features that developers love.
- Companies love the RMAN tool for backing up and easy recovery.
- Clustering is also offered by Oracle DB.
