Agile Software Development is a methodology that emphasizes iterative development, customer collaboration, and flexible planning. It's based on the Agile Manifesto, which promotes values like individuals over processes, working software over comprehensive documentation, customer collaboration over contract negotiation, and responding to change over following a plan.
Adaptive maintenance refers to the process of modifying existing software to adapt to changes in its environment, technology, or user requirements. This type of maintenance is essential to ensure that software remains relevant, functional, and valuable over time.
Key aspects of adaptive maintenance:
Environmental changes: Adapting to changes in the operating system, hardware, or other external factors.
Acceptance Testing is the final stage of software testing before a product is released to the end-users. It ensures that the software meets the specified requirements and is ready for production.
Key points:
User perspective: Acceptance testing is conducted from the end-user's point of view.
ODS: Operational Data Store in Data Warehousing
ODS stands for Operational Data Store. It's a specialized database that captures and stores data from operational systems in a format suitable for analysis. Unlike a data warehouse, which focuses on historical data and analytical reporting, an ODS is primarily concerned with current and recent data.
In-Memory Databases: A High-Performance Solution
In-memory databases are a type of database management system (DBMS) that primarily store data in the computer's main memory (RAM) rather than on disk. This significantly reduces data access latency, making them ideal for applications that require extremely fast response times.
