SQL (Structured Query Language) has been capacitating even IT novices to query relational databases extensively and descriptively since long. The PostgreSQL, an open source version, is weighing heavy on costly software counterparts released by Microsoft, Sybase, Oracle, and IBM. The software is maintained professionally and facilitates execution of complex data-driven applications with relative ease.The awareness of PostgreSQL techniques is suddenly attracting spotlight because its understanding is seen as an essential qualification for any aspiring Data Scientist. After all, a Data Scientist’s job has been declared as ‘The Sexiest Job of the 21
st Century’ by Harvard Business Review. Knowing how to query complex databases using PostgreSQL would certainly offer you an edge in recruitment for lucrative data science positions in the industry. With PostgreSQL training, you come to know how to leverage the functionalities of this software by getting hands-on exposure to projects in real time.
Why Should I Learn PostgreSQL?
The incentives for undertaking a course in PostgreSQL are many. The software is gradually becoming the industry standard for querying databases and building dynamic applications interacting with large sets of data. For having PostgreSQL as an academic accomplishment on your resume, the following persuasive facts about the program may prove motivating.
1. PostgreSQL is Open-Source
Yes, it is free to use forever. Software enthusiasts are adding more functional superiority to its source through rapid upgrades frequently. The documentation is comprehensive and detailed, which makes referencing its features easier. You would never have to pay a license renewal fee or feel intellectually throttled with limited functionalities of a demo version.
2. Database Features Are Advanced
PostgreSQL database system is exhaustive and sophisticated. It offers numerous features which are either available only in paid counterparts or are innovative in nature. The capability of the software can be understood from the fact that the documentation runs to nearly 3500 pages.
3. New SQL Functions Are Available
For querying database more powerfully, you can avail of newer functions like OVER-clause (Windowing analytics), WITH RECURSIVE, WITHIN GROUP (Ordered sets and Hypothetical aggregate), table sampling, FILTER clause, etc.
4. Countless Performance Boosters
PostgreSQL allows you to perform optimally with features like partitioned tables, queries optimized on advanced cost-driven consideration, COMMIT (both synchronous and asynchronous), tablespaces, sophisticated locking functionalities, and a variety of indices like gist, hash, bloom, btree, etc.
5. Replication Becomes Easier
You can replicate data tables easily with functions like quorum commits, physical, and logical replication, Create Publication command driven partial replication, Point in Time recovery, Patroni based auto-failover and high-availability, as well as asynchronous and synchronous replications.
6. Strong Security Features
PostgreSQL fully supports secured socket layer (SSL) mechanism, and single sign-on powered by AD (ActiveDirectory, Radius etc.). A database can be encrypted completely via PostgreSQL_fde. Authentication for users, roles, and others is robust.
7. Stored Procedures Supported
PostgreSQL supports custom aggregates and stored procedures (in different languages). It comes bundled with many useful professional triggers.
8. Professional Replication Available
You get to enjoy all the functionality needed to seamlessly work with database of all complexity levels. Replication has been integrated as a core feature. As such, you need to acquire a license for operating add-ons. A number of features are available which external tools also support.The aforementioned features along with many other advantages have rendered PostgreSQL as one of the most powerful and agile object-relational DBMS today. This enterprise-class system has been deployed for handling significantly huge workloads for renowned organizations worldwide.
