Structure Query Language (SQL) is a database query language used for storing and managing data in Relational DBMS. SQL is a standard language for accessing and manipulating databases where, you can insert records, update records, and delete records. You can also create new database objects such as databases and tables and you can drop (delete) them. Some of the advanced features in SQL includes creating stored procedures (self contained scripts), views (pre-made queries).

Oracle Certification and Path

The Oracle Certified Associate (OCA) credential is the first step toward gaining an Oracle Certified Professional certification. This certification makes sure that a candidate is well-equipped with fundamental skills.

Organizations are handling more data than ever, and a prominent aspect of big data is database management. The OCA certification has a good market value. It substantiates your proficiency to install, troubleshoot and maintain Oracle database architecture. It is framed for database admins, IT managers, software engineers, software developers and any professional who works intimately with Oracle’s database software. The OCA DBA is provided in three tracks comprising 11g, 12c and SQL.

The Oracle Certified Professional (OCP) credential is based on the fundamental skills shown by the OCA. This professional has command over a specific field of Oracle technology and has an excellent level of knowledge and skills. IT managers commonly use the OCP credential to evaluate the qualifications of employees and job aspirants.

The Oracle Certified Master (OCM) credential recognizes the highest level of proven skills and knowledge. OCMs are well-versed with the most difficult questions and solve the most complex issues. The OCM validates the aspiring candidate’s abilities through profound performance-based exams. The certification typically works on the fundamental skills of the OCA and the more advanced skills of the OCP.

The Oracle Certified Expert (OCE) credentials recognize proficiency in specific, niche-based technologies and architectures. The candidate should have a great understanding of both foundational skills and advanced technologies here. The Oracle Certified Specialist (OCS) credentials are typically implementation-based certifications that are framed on focused products or skill sets and provides a good analysis of a candidate’s level of competency in a particular domain.
