As the new types of databases are still created (e.g. NewSQL) and the number of information, which needs to be managed or retrieved increases in a geometry rate, some of the companies decided to create brand new role: Database Developer. Don’t confuse it with Database Administrator, whose responsibilities are a bit different. Developer designs and develops new features or programs that will cooperate with databases, as well as improves their performance. Where to look for those professionals? Take a look at our presentation!

3. Database? What’s that?
Organized collection of data
Excel spreadsheet or our trackers are also some kind of databases
One of the first DBMS - IMS (Information Management System) was
launched in 1966 by IBM for Apollo program
DBMS (Database Management System) is a software that helps
with storing, managing and retrieving information in the database

4. Maintenance for multiple users is much easier
Perform complex calculations and reports
Update records in bulk
Offers better security of the data
Why Not Spreadsheets?

5. Relational (SQL) database - data are
table-structured and linked to each other;
managed by SQL (Structured Query Language)
Object database - data are represented in the
form of objects (as in object-oriented
programming in Ruby or Scala)
NoSQL database - non relational; models of NoSQL
databases are: column, document, graph, key-value;
often used for Big Data and real-time apps
NewSQL database - new approach combining
RDBMS with NoSQL scalability; used for online
transaction processing
