Study Notes
SQL and Databases
- SQL is primarily used for managing and manipulating structured data within relational databases.
- Structured data in SQL is organized into tables, which consist of rows and columns, allowing for efficient querying and relationships between data entities.
- An example of unstructured data includes text files, images, videos, or social media posts, which do not follow a predefined data model.
Purpose of a Database
- The primary purpose of a database is to store, retrieve, and manage data efficiently, providing a systematic way to keep and access information.
RDBMS
- RDBMS stands for Relational Database Management System, which utilizes a relational model to manage data.
Prefabrication in Construction
- The primary purpose of prefabrication is to improve efficiency and reduce construction times by manufacturing components off-site before assembly at the final location.
- Examples of prefabricated units include walls, floors, and complete bathroom modules that can be installed quickly on-site.
History of Prefabrication
- The modern sense of prefabrication dates back to the early 20th century, where industrialization began influencing construction methods.
Pre-fab vs. Traditional Construction
- Pre-fab construction differs from traditional construction in that building components are manufactured in a factory setting, allowing for greater control and quality assurance before they are assembled on-site.
- Prefab constructions are faster to complete than traditional construction methods due to streamlined production processes and reduced on-site labor time, leading to quicker project turnaround.
