How To Become a Database Administrator?

How To Become a Database Administrator?

 How To Become a Database Administrator?

Becoming a database administrator (DBA) typically involves a combination of education, experience, and specific skills. Here’s a general roadmap to becoming a DBA.

1. Education

Start with a relevant bachelor’s degree in Computer Science, Information Technology, or a related field. Some employers may prefer candidates with a master’s degree for senior positions.

2. Gain Technical Skills

Database Systems: Develop proficiency in popular database management systems (DBMS) such as MySQL, PostgreSQL, Oracle, SQL Server, MongoDB, etc.

3. SQL

Master SQL (Structured Query Language) for querying and managing data in databases.

4. Data Modeling 

Understand data modeling techniques to design efficient database schemas.

5. Backup and Recovery

Learn about database backup, recovery, and disaster recovery procedures.

6. Performance Tuning

Gain skills in optimizing database performance through indexing, query optimization, etc.

6. Gain Experience

Start with entry-level roles like database developer or data analyst to gain hands-on experience with databases.

Progress to roles that involve more database administration responsibilities as you gain experience.

7. Certification

Consider obtaining certifications from database vendors (e.g., Oracle Certified Professional, Microsoft Certified Solutions Expert) to validate your skills and knowledge.

8. Soft Skills

Develop good communication skills, problem-solving abilities, and the ability to work under pressure, as DBAs often need to handle critical database issues.

9. Stay Updated

Keep up with industry trends and new technologies in database management.

10. Networking

Build a professional network through industry events, forums, and online communities to stay connected and learn from others in the field.

What is time, exactly? Physicists define time as the progression of events from the past to the present into the future. Basically, if a system is unchanging, it is timeless. Time can be considered to be the fourth dimension of reality, used to describe events in three-dimensional space. It is not something we can see, touch, or taste, but we can measure its passage.

What is jQuery?

 What is jQuery?

jQuery is a classic JavaScript library that’s fast, light-weight, and feature-rich. It was built in 2006 by John Resig at BarCamp NYC. jQuery is free and open-source software with a license from MIT.

It makes things simpler for HTML document manipulation and traversal, animation, event handling, and Ajax.

According to W3Techs, 77.6% of all sites use jQuery (as of 23rd February 2021).

Features/Benefits:

It has an easy-to-use, minimalistic API.

It uses CSS3 selectors in manipulating style properties and finding elements.

jQuery is lightweight, taking just 30 kb to gzip and minify, and supports an AMD module.

As its syntax is quite similar to that of CSS, it is easy for beginners to learn.

Extendable with plugins.

Versatility with an API that supports multiple browsers, including Chrome and Firefox.

Use cases:

DOM manipulation with CSS selectors that use certain criteria to select a node in the 

DOM. These criteria include element names and their attributes (like class and id).

Element selection in DOM using Sizzle (an open-source, multi-browser selector engine).

Creating effects, events, and animations.

JSON parsing.

Ajax application development.

Feature detection.

Control of asynchronous processing with Promise and Deferred objects.

What Are JavaScript Libraries?

What Are JavaScript Libraries?

 What Are JavaScript Libraries?

JavaScript libraries contain various functions, methods, or objects to perform practical tasks on a webpage or JS-based application. You can even build a WordPress site with them.

Think of them as a book library where you revisit to read your favorite books. You may be an author and enjoy other authors’ books, get a new perspective or idea, and utilize the same in your life.

Similarly, a JavaScript library has codes or functions that developers can reuse and repurpose. A developer writes these codes, and other developers reuse the same code to perform a certain task, like preparing a slideshow, instead of writing it from scratch. It saves them significant time and effort.

They are precisely the motive behind creating JavaScript libraries, which is why you can find dozens of them for multiple use cases. They not only save you time but also bring simplicity to the entire development process.
