Overview of Oracle Certification
Since the beginning of the computing era, we have gathered information and data, always seeking more data from databases and analyzing it. The majority of the significant cloud suppliers currently offer managed RDBMS, for example, Amazon RDS, Google Cloud SQL, and Azure Database for Postgre SQL.
We as a IT Services and Consulting Company India, explore why there is a demand for oracle SQL certification these days by explaining the features of SQL but before that, we must understand what SQL truly is. Structured Query Language (SQL) is an ANSI and ISO common computer language for creating, operating, and manipulating databases.
SQL allows an individual to create, update, delete, and retrieve data from a database. SQL is very simple to learn. SQL works along with database programs such as DB2, Oracle, MS Access, Sybase, and MS SQL Server, for example. SQL is generally famous because of its advantages:
- It helps in describing the data.
- SQL helps you in accessing the data in RDBMS.
- It gives you the ability to manipulate the data in the database.
- It enables you to build and drop tables and databases.
- You can et permissions on tables and views with SQL.
- With the use of SQL modules and libraries, SQL enables you to embed the components within other languages.
The characteristics of SQL give advantages to a wide range of clients, including application developers, database managers, and administrators., SQL is an information sublanguage. The concept behind SQL is to give an interface to a relational database, like Oracle Database.
Check out the following features of SQL that made the Oracle SQL certification successful:
1. Vendor Independence:
Throughout the last decade, no database product has been thoroughly effective without SQL support. A SQL based database can be transferred from one DBMS to another efficiently. Vendor independence subsequently offered by SQL was an exceptional feature which helped its early prominence, and still remains vital today.
2. Portability Across Computer Systems:
SQL based databases can run on computer frameworks extending from midrange frameworks to PCs, workstations, and even handheld devices. They perform functions on stand-alone frameworks and in enterprise-wide or Internet-wide networks. SQL based applications that begin on a single user or departmental server systems can be moved to larger server systems as they grow.
3. Relational Foundation:
SQL, being the language for relational databases, has become prominent in recent years. The SQL language is simple to understand because users find the row/column structure of the relational database to be interactive. The strong hypothetical establishment of the relational model additionally, has guided the implementation of relational databases.
4. English – Like Structure:
Since statements of SQL appear just like English sentences, SQL is quite easy to learn and understand. SQL statements, to some extent, describe the information to be recovered, instead of determining how to search for the information. Consequently, SQL statements “state what they signify” and can be read as clear sentences.

5. Highly Interactive:
Since SQL is an intuitive query language, it provides users ad hoc access to store information. By utilizing SQL intuitively, a user can also find solutions to complicate queries in minutes as oppose to the days or weeks that it would take for a programmer to compose a custom report program. SQL’s ad hoc query feature makes information more accessible than before and enables an organization to make informe decisions.
6. Programmatic Database:
SQL is utilize by developers to compose applications that access a database. The parts of a program can be test before being embedded using the same SQL statements for both interactive and programmatic access. On the other hand, old databases use to provide one set of tools for programmatic access and a different facility for ad hoc requests, with no synergy between both.
7. Enterprise Application Support:
Big-enterprise applications that provide support to an organization’s day to day operations utilize SQL base databases to store and arrange information and data. Information about business transactions, like orders, sales, client information, stocks, and so forth usually, have organize records and field layouts which can be convert effectively into the row/column format of SQL.
