What is a system design interview? A system design interview is conducted to allow candidates—like programmers, designers, developers and software engineers—sufficient opportunity to prove expertise in the field through the tangible application of knowledge to solve a real problem that a company might be facing. 1) Architectural design: To describes the views, models, behaviour, and structure of the system. 2) Logical design: To represent the data flow, inputs and outputs of the system. Example: ER Diagrams (Entity Relationship Diagrams). ... b) How the data is modelled and stored within the system. Tanya Sanchez

What do you mean by formally managing information?What kind of information do you want to manage?There are many different fields in managing information. For project management, you can use software like FreedCamp and Trello.If you are more of a developer, then perhaps you need a tool to draw class diagrams, sequence diagrams, or an entity-relationship diagram for your database. Consider tools such as StarUML and Visual Paradigm.Perhaps your boss wants you to find out the true cost of a business process, or maybe reengineer a business process. In that case, it would be useful to draw out and simulate them with tools such as Business Process Simulator or again, Visual Paradigm (yep it’s quite a good tool).For people that are into analytics, you might want to start off by visualising data with MicroStrategy or Tableau.Currently, I am learning about simulation. There are problems in the world that is very difficult to explain with a few formulas or statistics. Sometimes, it is clearer to simulate the situation and tinker with the parameters. In that case, you might be interested in NetLogo.For people who likes to do spatial visualisation, QGIS might be the tool you need.Alternatively, you might want to use RStudio. With a little bit of knowledge in programming, you can turn data into a web application. Check out one of my project here. RStudio is also commonly used by mathematician and economists.You might want to also explore using cloud infrastructure such as Amazon Web Service (AWS) or Google Cloud or SAP Cloud Platform. Many systems now are moving towards using cloud infrastructure. In many cases, it makes more business sense as the cost are lower, the system becomes scalable (not restricting business growth) and you can make use of awesome technologies provided such as machine learning, natural language processing, and dynamic databases.For each aspect I mentioned, there are tons of other software out there for you to try. And of course, I did not mention a lot of other systems to manage other kind of information.For example, there are accounting systems out there for small businesses. SAP also provide enterprise resource planning systems (ERP) for large businesses to manage the operation of a business on a large scale (think inventory, ordering, production, HR, accounting etc). Microsoft also provides lots of infrastructure and software to help businesses collaborate and document their work.My knowledge is limited. I hope I gave you a flavor of what you are asking for. Sorry if I did not understand your question too well.
