This document discusses database system concepts and architecture. It covers several topics:
- Data models define database structure, operations, and constraints. Common categories are conceptual, physical, and implementation models.
- Schemas describe database structure and constraints, while instances represent actual stored data. The three-schema architecture separates conceptual, internal, and external schemas.
- Data independence allows changes to lower-level schemas without affecting higher levels.
- DBMS languages include DDL for definition and DML for manipulation. Interfaces provide access for users, programmers, and administrators.
- Database architectures range from centralized to client-server. Client-server divides processing between client machines and centralized database servers.
The document discusses database system concepts and architecture. It covers topics such as data models, schemas, instances, the three-schema architecture, data independence, DBMS languages, interfaces, utilities, centralized and client-server architectures, and classifications of DBMSs. The three-schema architecture defines schemas at the internal, conceptual, and external levels to support data independence. DBMS languages include data definition languages to define schemas and data manipulation languages to retrieve and update data. Client-server architectures distribute the database system across network tiers, with specialized database, application, and interface servers.
This document provides an overview of database system concepts and architecture. It discusses data models, schemas, instances, and states. It also describes the three-schema architecture, data independence, DBMS languages and interfaces, database system utilities and tools, and centralized and client-server architectures. Key classification of DBMSs are also covered.
This document discusses database system concepts and architecture. It covers topics such as data models and their categories, schemas and instances, the three-schema architecture, data independence, DBMS languages and interfaces, and centralized and client-server architectures. The three-schema architecture defines three levels of schemas - internal, conceptual, and external - to support program-data independence and multiple views of the data. Data independence allows changes to lower-level schemas without affecting higher-level schemas and applications. A variety of DBMS languages exist, including DDL for schema definition and DML for data manipulation.

Voxxed Days Trieste 2024 - Unleashing the Power of Vector Search and Semantic...Luigi Fugaro
Vector databases are redefining data handling, enabling semantic searches across text, images, and audio encoded as vectors.
Redis OM for Java simplifies this innovative approach, making it accessible even for those new to vector data.
This presentation explores the cutting-edge features of vector search and semantic caching in Java, highlighting the Redis OM library through a demonstration application.
Redis OM has evolved to embrace the transformative world of vector database technology, now supporting Redis vector search and seamless integration with OpenAI, Hugging Face, LangChain, and LlamaIndex. This talk highlights the latest advancements in Redis OM, focusing on how it simplifies the complex process of vector indexing, data modeling, and querying for AI-powered applications. We will explore the new capabilities of Redis OM, including intuitive vector search interfaces and semantic caching, which reduce the overhead of large language model (LLM) calls.
