Information technology certifications are highly respected testaments to a professional’s training and expertise in Information Technology. Whether you’re changing careers, branching into another facet of IT, or completely new to the IT sector, pursuing certification is a fast track to recognizable and transferable skills attractive to many employers. For example, studies show that certified professionals are able to handle over a third more tech support cases than non-certified employees.
Pursuing IT certifications used to be both expensive and inconvenient. New online courses enable you to jumpstart a new career through straightforward and highly accessible online training. Brenner Spear, a content developer at OpenSesame, a company that offers online training courses, talks about the top three IT certifications and how you can get them.
Oracle Certified Professional Java SE 6 Programmer
Time Commitment: 21 hours of course material + 2.5 hour exam
Financial Commitment: $80 course + $300 exam fees
The median starting salary for an individual with an OCPJP certification is $50,800, which usually grows by $11,000 within the first 4 years of certification. There are currently 130+ jobs on Freelancer.com that require a Java programmer.
To become an OCP Java Programmer, there’s only one exam you have to take: the Java SE 6 Programmer Certified Professional Exam. OpenSesame.com offers 1Z0-851 Study Exam Material, a comprehensive 21-hour interactive course covering the seven sections of the exam. These are a few of the topics covered in each section of the exam:
Section 1: introduces classes, methods, objects and arrays as variables, and how to declare an interface.
Section 2: covers if & switch statements, for loops, for-each loops & while loops, and exceptions & exception handling (try, catch, finally).
Section 3: teaches how to navigate file systems using FileReader and FileWriter, as well as integrate data from other code using APIs.
Section 4: explains the different states in which a thread can exist.
Section 5: describes the effect of modifiers on inheritance.
Section 6: explains the process of determining which collection of classes would be best for different designs, as well as the different versions of the collections API.
Section 7: introduces the garbage collection system, and how to recognize when objects are ready for garbage collection.
Alternatively, you may purchase a self-study CD set for $660 from Oracle themselves. When you have completed the study process, you can take the certification exam at an Oracle Testing Center or through Pearson VUE. Register for either through Oracle. This is probably the fastest way to get a credible certification stating you’re a “professional.”
Oracle Database Administrator Certified Associate
Time Commitment: 31 hours of course material + two 1.5-2 hour exams
Financial Commitment: two $80 courses + $320 (total) exam fees
OCA Database administrators earn a median of $40,000 annually, which usually grows by $23,000 within the first 4 years. To become an OCA Database Administrator, you must complete two required exams, the 1Z0-051: Database SQL Fundamentals & the 1Z0-052: Database SQL Administration. Mindleaders, a seller in the OpenSesame marketplace, offers material for both.
The Oracle 1Z0-051 Exam Study Material presents 12 hours of material cut into seven sections which cover the basics of SQL database management. No experience is needed to take this course. Some of the topics in each section include:
Section 1: introduces the SELECT statement and how to limit/sort the rows retrieved.
Section 2: introduces and explains the four main functions: SELECT, INPUT, DELETE & UPDATE.
Section 3: covers group functions, and how to use GROUP BY & HAVING.
Section 4: explains how to use JOIN commands, as well as what subqueries are.
Section 5: describes, in depth, DML (data manipulation language) and DML statements.
Section 6: teaches how to create tables and add constraints during their creation.
Section 7: describes simple & complex views, and the differences between them. Explains sequences & indexes, as well as public & private synonyms.
Section 1: explains memory structures and storage structures, and how to use all the tools for administering an Oracle database.
Section 2: teaches how to create a database with the DBCA (Database configuration Assistant) and set it up the way you want/need it.
Section 3: shows how to manage database storage structures and schema objects, as well as how to correctly use temporary tables.
Section 4: covers network architecture and how to configure an Oracle Network Environment correctly.
Section 5: explains how to keep an Oracle database secure by controlling accounts and privileges, as well as standard database auditing.
Section 6: teaches how to recognize PL/SQL objects, and how to use undo and undo data.
Section 7: covers an array of helpful tools, such as: automatic memory management, AWR (automatic workload repository), advisory framework, and memory advisors.
Section 8: explains the concepts of backup and recovery, and how to make automated routine incremental backups.
Section 9: covers the types of failures Oracle databases can experience and how to recover from them.
Section 10: teaches how to import and export data using the Oracle data pump, as well as manage any patches released.
Both courses include three full-length practice exams to test your grasp of the material. When it comes to exam day, only a 60% and 66%, respectively, are required to pass. If you have some database experience, passing the 051 with no studying is probably possible, but it won’t help your overall understanding of Oracle-specific topics, which could be a hindrance when taking the 052 course and exam.
Interested? Register for both exams with Oracle - the 1Z0-051 exam is even available online. Oracle also offers on-demand prep-seminars (videos) for both the 1Z0-051 and the 1Z0-052, for $650 a piece.
