A Review of Databasteknik by Thomas Padron-McCarthy and Tore Risch
Databasteknik is a book about database technology written by Thomas Padron-McCarthy and Tore Risch, published by Studentlitteratur in 2005. It is based on a web course on databases that the authors have taught in various courses. The book covers topics such as data models, relational algebra, SQL, database design, transactions, concurrency control, recovery, security, and distributed databases. It also includes exercises and code examples in different languages such as ODBC, ESQL, and JDBC.
The book is intended for students and practitioners who want to learn the fundamentals of database technology and how to use it in practice. It assumes some basic knowledge of programming and mathematics, but does not require any prior experience with databases. The book is written in a clear and pedagogical style, with many examples and illustrations. The book also has a website where readers can find answers to exercises, code examples, errata, and additional material.

Databasteknik is a comprehensive and up-to-date introduction to database technology that covers both theory and practice. It is suitable for anyone who wants to learn more about databases and how they work. The book is available for purchase online or directly from Studentlitteratur.In addition to the topics covered in the book, there are some emerging trends and challenges in database technology that are worth paying attention to in 2022. Some of these trends include:
Cloud-based DBMS: More and more organizations are moving their data and applications to the cloud, which requires a DBMS that can handle different data formats, scalability, availability, and security. Cloud-based DBMSs offer advantages such as lower costs, faster deployment, and easier maintenance. However, they also pose challenges such as data migration, integration, governance, and compliance. Some of the popular cloud-based DBMSs are Amazon RDS, Google Cloud SQL, Microsoft Azure SQL Database, and Oracle Cloud Database[^1^].
Automation and DBMS: As the volume and complexity of data increase, so does the need for automation in data management. Automation can help reduce human errors, improve efficiency, and optimize performance. Automation can be applied to various aspects of DBMSs, such as data ingestion, cleansing, transformation, analysis, backup, recovery, and tuning. Some of the tools and techniques that enable automation in DBMSs are artificial intelligence (AI), machine learning (ML), natural language processing (NLP), robotic process automation (RPA), and self-driving databases[^1^].
Augmented DBMS: Augmented DBMS is a term coined by Gartner to describe a DBMS that uses AI and ML to enhance its capabilities and user experience. Augmented DBMS can provide features such as natural language query (NLQ), natural language generation (NLG), data discovery, data visualization, data quality assessment, data lineage tracking, data security analysis, and data recommendation[^1^]. Augmented DBMS can help users interact with data more easily and intuitively, as well as gain deeper insights and make better decisions.
Increased security: Data security is a paramount concern for any organization that deals with sensitive or confidential data. Data breaches can result in financial losses, reputational damage, legal liabilities, and regulatory penalties. Therefore, DBMSs need to provide robust security mechanisms to protect data from unauthorized access, modification, or deletion. Some of the security features that DBMSs should offer are encryption, authentication, authorization, auditing, masking, anonymization, tokenization, and firewall[^1^].
