? DVD Rental Database
A business on DVD Rental is a real life example of database application.
For instance the enterprise may track information about DVDs, employees,
customers and their phone numbers and the movies they offer along with details
such as their genre, addresses, ages...
Without the use of the database system the rental shop has to maintain scattered
DVD records and customer information. A centralized database will help to
provide general accessibility to this information as well as ensuring that the data
is preserved more securely.
The system may provide not only the features stated above and some other
features .

INT 1010 07-1.pdfLuis R Castellanos

This document discusses databases and their importance in information systems. It begins by defining data, information, and knowledge, explaining how data is transformed into useful information and knowledge through organization and context. It then describes different types of databases, focusing on flat file databases and relational databases. Flat file databases store all data in one file but have limitations around data duplication, searchability, and concurrent access. Relational databases break data into normalized tables with relationships between them, addressing those limitations through their structure and use of queries. The document provides examples to illustrate key differences between the two database types.

2 ddb architectureMr Patrick NIYISHAKA

This document discusses distributed database architecture. It describes the advantages as improved processing power through distributed processing across multiple machines, removal of single point of failure, and easier expandability. The disadvantages include increased complexity, costs, security challenges, and difficulties with integrity control and standardization. Different architectures are shared-nothing, shared-disk, and shared-memory. Distributed databases are well-suited for applications involving multiple sites like manufacturing, military systems, and airline reservations.

1 ddbMr Patrick NIYISHAKA

1. The document discusses types of distributed databases and distributed database architecture. It describes distributed databases as collections of shared data distributed over a computer network. Distributed databases can be either homogeneous, with all sites using the same DBMS, or heterogeneous, with different sites using different DBMSs. A distributed DBMS manages the distributed database and aims to make the distribution transparent to users.

2 countermeasuresMr Patrick NIYISHAKA

This document discusses various countermeasures for database security including authorization, authentication, backups, journalizing, encryption, RAID technology, user-defined procedures, and checkpoints. It also discusses responses to different types of database failures such as aborted transactions, incorrect data, system failures with the database intact, and total database destruction. The preferred and alternative recovery approaches are outlined for each failure scenario.

4 summaryMr Patrick NIYISHAKA

This document covers transaction processing concepts including: - Typical OLTP environments and how to recover from failures - The ACID properties of transactions including atomicity, consistency, isolation, and durability - Transaction states like active, aborted, and committed - Transactions as concurrency units and how they execute concurrently while maintaining serializability - Quizzes to test understanding of transaction processing, ACID properties, transaction states, and ensuring consistency through synchronization

3 summaryMr Patrick NIYISHAKA

This document discusses concurrency control techniques for managing concurrent execution of transactions. It provides an example of how concurrency control is needed when multiple passengers try to purchase the last remaining airline ticket. The document then covers topics like transaction serialization, pessimistic and optimistic concurrency control, locking techniques, and two-phase locking. It concludes with sample multiple choice questions about problems with concurrent transactions, methods for serialization, locking data items, and definitions of deadlock and concurrency control.

2 con controlMr Patrick NIYISHAKA

1 con exeMr Patrick NIYISHAKA

This document discusses concurrency control and methods to ensure serializability when transactions execute concurrently in a database. It begins by describing three problems that can occur with concurrent transaction execution: lost updates, unrepeatable reads, and dirty reads. It then explains two methods for achieving serializability: multi-version concurrency control and timestamp ordering. Timestamp ordering assigns timestamps to transactions and data items and uses the timestamps to determine when transactions can read and write data items to prevent conflicts. The document also briefly mentions using concurrency control protocols that employ locking to serialize transaction access.

1 basic conceptsMr Patrick NIYISHAKA

This document discusses transaction processing in online transaction processing (OLTP) environments. It covers typical OLTP environments like airline, banking, and trading systems. It also covers topics like transactions being atomic units of execution that must have ACID (atomicity, consistency, isolation, durability) properties and can be in different states during processing. Transactions are sequences of database operations that must generate a consistent database when applied to a consistent one.

2 recoveryMr Patrick NIYISHAKA

The document discusses database recovery from failures. It explains that a DBMS uses techniques like logging transactions, periodic backups, and mirroring databases to restore the system to a consistent state if a failure occurs. There are two types of recovery - from transaction failures, where the DBMS undoes uncommitted transactions, and from catastrophic failures like disk or system crashes, where the entire database must be restored from a backup and the log is used to replay committed transactions. Proper recovery is needed to ensure transactions are fully committed or have no effect, and that the database remains in a consistent state.

3 transactionMr Patrick NIYISHAKA

The document discusses the ACID properties that transactions should possess: 1. Atomicity - Transactions are atomic units that are fully completed or not completed at all. 2. Consistency - Transactions preserve consistency by ensuring the database only transitions between valid states. 3. Isolation - The execution of one transaction is isolated and not interfered with by other concurrent transactions. 4. Durability - Committed transaction changes persist in the database and survive failures through logging and recovery.

3 summaryMr Patrick NIYISHAKA

The document discusses query processing and optimization techniques. It provides an example of querying a database to find the name of the last member to borrow a book with the title "Zeus". There are several ways to structure the query, but some methods are more optimized than others. Query processing involves translating SQL queries into relational algebra operations, generating execution plans, and executing the queries. Query optimization examines multiple query plans to identify the most efficient plan to retrieve the required data.

1 query processingMr Patrick NIYISHAKA

2 optimizationMr Patrick NIYISHAKA

The document discusses query optimization techniques used by database systems. It describes how a database catalog is used to estimate query execution costs. Alternative execution plans are enumerated using heuristic rules and the lowest cost plan is selected. Examples are provided of applying translation rules to optimize a query tree by pushing down select and project operations, avoiding Cartesian products, and reordering joins and selections. Cost estimation considers factors like I/O, memory usage, and computation to select a suboptimal but efficient execution plan.

Developer Experience is Dead! Long Live Developer Experience! In this keynote-style session, we’ll take a detailed, granular look at the barriers to productivity developers face today and modern approaches for removing them. 10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’ Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method, we invent to deliver products, whether physical or virtual, we reinvent productivity philosophies to go alongside them. But which of these approaches works? DORA? SPACE? DevEx? What should we invest in and create urgency behind today so we don’t have the same discussion again in a decade?

Formal Methods: Whence and Whither? [Martin Fr?nzle Festkolloquium, 2025]Jonathan Bowen

Alan Turing arguably wrote the first paper on formal methods 75 years ago. Since then, there have been claims and counterclaims about formal methods. Tool development has been slow but aided by Moore’s Law with the increasing power of computers. Although formal methods are not widespread in practical usage at a heavyweight level, their influence as crept into software engineering practice to the extent that they are no longer necessarily called formal methods in their use. In addition, in areas where safety and security are important, with the increasing use of computers in such applications, formal methods are a viable way to improve the reliability of such software-based systems. Their use in hardware where a mistake can be very costly is also important. This talk explores the journey of formal methods to the present day and speculates on future directions.
