This document discusses database management systems (DBMS) and database design. It provides definitions of key concepts including:
- A DBMS allows for easy collection, retrieval, and updating of stored data across an organization.
- The database design process involves understanding real-world entities and relationships, creating entity-relationship diagrams, normalizing data tables, and refining the design if needed.
- Entity-relationship modeling defines entities, attributes, keys, and relationship types such as one-to-one, one-to-many, and many-to-many.
- The database design process results in a logical data model that represents the structure for an organization's database.
Database management system
A database is an organized collection of data that models aspects of reality. Database management systems (DBMS) allow users and applications to define, create, query, update, and administer databases. Well-known DBMS include MySQL, PostgreSQL, Microsoft SQL Server, Oracle, SAP, and IBM DB2. A DBMS includes components for data definition (DDL), data manipulation (DML), optimization and execution, data security and integrity, data recovery and concurrency, and a data dictionary. The DBMS architecture has three levels - an external level for users, a conceptual level representing the database contents, and an internal level for low-level storage.

Database system architecture
Centralized systems run on a single computer system and do not interact with other systems. Client-server systems divide database functionality between a back-end that manages data and a front-end for user interaction. Parallel and distributed systems use multiple interconnected computers to improve performance and availability.
What is difference between dbms and rdbms
DBMS stores data as files while RDBMS stores data in tabular form with relationships between tables. DBMS is meant for small organizations and single users, does not support normalization, and lacks security features. RDBMS supports large data, multiple users, normalization, security, distributed databases, and examples include MySQL, PostgreSQL, and Oracle. The key difference is that RDBMS represents data in tables with relationships while DBMS stores data as files without relationships.

Ism normalization pine valley 2012
The document discusses database normalization concepts including first normal form (1NF), second normal form (2NF), and third normal form (3NF). 1NF requires removing duplicate columns, 2NF removes redundant data by separating subsets of data that apply to multiple rows into new tables, and 3NF removes columns that are not dependent on the primary key. The document also provides examples of normalization exercises and applying normalization rules to sample data.
Normlaization
The document discusses database normalization through three forms:
1) First normal form (1NF) involves eliminating repeating groups and defining primary keys so that each attribute depends on the full primary key.
2) Second normal form (2NF) builds on 1NF and removes partial dependencies by splitting tables where attributes depend on only part of a composite primary key.
3) Third normal form (3NF) builds on 2NF and removes transitive dependencies by splitting tables where a non-key attribute depends on another non-key attribute rather than the primary key. The goal is to isolate each functional dependency and minimize data anomalies.

Safelyio Toolbox Talk Softwate & App (How To Digitize Safety Meetings)
Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices.
These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions.
Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site.
The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages.
Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information.
This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/
Measures in SQL (SIGMOD 2024, Santiago, Chile)
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.
