Examples: Oracle, SQL, sysbase,DB2 etc..


Next we should know about SDLC IN THE PART OF IT BASICS:

SDLC: It stands for Software Development Life Cycle.  It is used to develop software products.

The Life Cycle will be as Follows:

• Requirement Analysis
• Software Design
• Implementation
• Coding
• Deployment
• Maintenance

SDLC Methods:

SDLC methods are Agile method, Waterfall method,spiral method etc..


Next thing we should have knowledge on the software Architect or Design:

Software Architecture:

This is used to designing the product using Technical standards and software tools.

Testing Types:

1) Manual Testing
2) Automation Testing

Software Deployment:

After Testing the software we need to Deploy(install) software. That means make software Active or De Active. Finally you must release the software into the market

 Software Support and Maintenance:

In this we provide support for the product to improve the performance of the product. At the same time it increasing the software maintainability and also reliability to prevent problems in feature.
