LLDH is a five-letter word that may seem intimidating to pronounce, but it is actually quite simple. In IPA phonetic transcription, it is spelled as /ɛldɛtʃ/. The first two letters, "EL," are pronounced like "ell." The "D" is pronounced like "dee," and the final two letters, "H," are pronounced like "hatch." When pronounced together, the word sounds like "el-dee-hatch." The spelling of this word may seem unusual, but it is an acronym used in the field of biochemistry to represent an enzyme.
LLDH stands for Low-Level Design Handbook. It refers to a comprehensive guide or manual that provides detailed information regarding the low-level design of a software system or application. This handbook outlines the specific features, functionalities, and technical aspects of the system, illustrating how it operates at a granular level.
The LLDH is typically created after the high-level design phase, where the overall system architecture and requirements have been established. It serves as a crucial resource for software developers, engineers, and other stakeholders involved in the software development lifecycle, providing them with a clear blueprint to implement the system's design accurately.
Within the LLDH, various components of the software system are described in detail, including their interactions, dependencies, data structures, algorithms, and interfaces. The handbook also covers the programming languages, frameworks, and technologies used in the implementation process. It may include class diagrams, flowcharts, sequence diagrams, data flow diagrams, and other visual representations to enhance understanding.
The purpose of the LLDH is to ensure consistency, maintainability, and efficiency in the development process. By providing a detailed plan for the low-level design, it helps developers understand how to translate the high-level design into actual code, ensuring that the system operates as intended. Moreover, the LLDH serves as a communication tool, facilitating collaboration among developers by establishing a common understanding of the system's design.
