Topic 8: Database Design

A well-designed database will provide users with accurate, timely and relevant information. It centralises data and reduces data redundancy and inconsistency as compared to traditional ways of organising data (Several master files by various departments in an organisation). We will focus on the recent developments of database design, notably cloud databases and open source databases.

In other words, people can type a database query in normal human languages and they will be able to get an answer to their query from a database. Salesforce achieved this technology by collecting information from Wikipedia and used this information to generate possible SQL queries, from which human questions were developed. The data set of questions is currently the largest of its kind.

17. What is a graph database? A better way to store connected data?

Link: https://www.infoworld.com/article/3263764/database/what-is-a-graph-database-a-better-way-to-store-connected-data.html

Unlike the traditional relational or SQL database in which relationships are implemented with foreign keys and queried by joining tables. Graph database stores the relationships along with the data, as related nodes are physically linked in the database. This allows graph database to work best when the data is highly connected or when it contains “many-to-many” relationships between entities (E.g. Social Media). Moreover, it can also find patterns of connection within the graph data to detect an abnormality in the case of Fraud detection system.

22. Get The Basics On NoSQL Databases: Wide Column Store Databases

Link: https://www.forbes.com/sites/metabrown/2018/03/31/get-the-basics-on-nosql-databases-wide-column-store-databases/2/#1d0b64ee6a01

Wide column stores databases are database management systems that organise related facts into columns. Groups of these columns, called “column families”, have content and function similar to tables in relational databases. A wide column store database is superior to a relational database as one single column in a wide column store database can include information that would take up many rows in a conventional relational database. Wide column store databases are useful in managing large amounts of data that has to be stored on multiple computers. Column-oriented databases can reduce query time by reducing the amount of data traversed to find the information required. However, whether the advantage can be harnessed depend on the type of query.

25. 3 Essential DBA Career Priorities For 2018

Link: https://www.forbes.com/sites/oracle/2018/01/15/3-essential-dba-career-priorities-for-2018/#f6fbaa613bc5

Many database administrators (DBAs) will go into 2018 wondering if “self-driving” databases (introduced by Oracle in October 2017) will weaken their career prospects. The self-driving database has the ability to automatically and continuously patch, tune, back up and upgrade itself without manual intervention, all while the system is running. Similar to the crunch of human labour due to automation technologies, it is no different for database managers. Therefore, they have to continually upgrade themselves and stay ahead of the developing trends before they become a thing of the past.

27. Why University Networks Are So Tempting to Foreign Hackers

Link: https://slate.com/technology/2018/03/why-foreign-hackers-target-university-networks.html

Iranians were apprehended for stealing information from databases through email phishing and infiltration. They mainly targeted databases belonging to universities in the US, obtaining access to journals, research papers and textbooks. University networks are vulnerable as the very design that was made for individuals within the campus to share and collaborate, also allowed hackers to gain unauthorised access. The abovementioned hackers would then sell the information such as account credentials to students that desire this information.

 

28. I downloaded the information that Facebook has on me. Yikes!

Link: https://www.nytimes.com/2018/04/11/technology/personaltech/i-downloaded-the-information-that-facebook-has-on-me-yikes.html

Following the recent Facebook privacy scandal, people have endeavoured to download their own files in order to catch a glimpse of exactly what information Facebook has on them. While we are all aware of how ads and cookies are saved on our accounts, the truth is far more appalling. Facebook actually retains far more than we think. To name a few: your detailed contact list linked from Messenger, the obscure locations of every single time you logged into your account, and a record of all the users you unfriended. Not only that, but the Advertisement industry tapping on Facebook to market itself also holds your information hostage.

 

29. How DNA could store all the world’s data

Link: https://www.ft.com/content/45ea22b0-cec2-11e7-947e-f1ea5435bcc7

Researchers have recently managed to store, decode and playback music recordings on DNA, without any loss of quality. DNA storage is a serious prospect for the future as data grows big and will require huge spaces of storage. Using current data storage systems will result in huge servers. DNA can provide that huge amount of data storage in a small space. DNA storage involves translating the binary code which makes up digital data into the chemical rungs that form DNA spirals. A DNA strand will be built from the sequence and it is run through a sequencer to be decoded.

 

30. New job: Data Storytellers

Link: https://www.youtube.com/watch?v=IIMHicxQ0LY

For thousands of years, storytelling has been an integral part of our humanity. Modern-day storytelling is often associated with the popular TED talks series and its slogan of “Ideas Worth Spreading.” Analysis of the most popular 500 TED Talk presentations found that stories made up at least 65% of their content. Throughout time, storytelling has proven to be a powerful delivery mechanism for sharing insights and ideas in a way that is memorable, persuasive, and engaging. However, many of the heavily-recruited individuals with advanced degrees in economics, mathematics, or statistics struggle with communicating and telling the story of their numbers. They may believe the revealed insights alone should influence the right decisions and drive their audience to act.

32. An Indian State Is Building a Massive, Blockchain-Based DNA Database

Link: https://gizmodo.com/an-indian-state-is-building-a-massive-blockchain-based-1825182830

India’s eighth largest state is seeking to build a blockchain-based DNA database of all 50 million of its citizens.  With it, the state’s government will be able to aid in the discovery of a person’s chances of cancer as well as even leading to cures for genetic disease.  Joining the database will be optional, and researchers and governments will be allowed to buy or access anonymous raw genomic data stored on the blockchain in the cloud. Of course, with this comes all the security and privacy concerns that come with the storing of the Indian citizens’ private information, much like India’s massive, nationwide biometric data collection programs under scrutiny.
