PRACTICAL 4: Drawing Engineering Diagram Using Dia

Dia is free and open source general-purpose diagramming software, developed originally by Alexander Larsson. Dia uses a controlled single document interface (SDI) similar to GIMP and Inkscape.
Dia has a modular design with several shape packages available for different needs: flowchart, network diagrams, circuit diagrams, and more. It does not restrict symbols and connectors from various categories from being placed together.
Dia has special objects to help draw entity-relationship models (obsoleted tedia2sql or newer parsediasql can be used to create the SQL DDL), Unified Modeling Language (UML) diagrams, flowcharts, network diagrams, and simple electrical circuits. It is also possible to add support for new shapes by writing simple XML files, using a subset of Scalable Vector Graphics (SVG) to draw the shape.
Dia loads and saves diagrams in a custom XML format which is, by default, gzipped to save space. It can print large diagrams spanning multiple pages and can also be scripted using the Python programming language.
Dia can export diagrams to various formats including PNG, VDX, EPS.

 Dia can be downloaded from http://dia-installer.de/

Question 1 - What is Apache spark? why spark has come into existence? brief architecture of Apache                              Spark Answer 1 -  Apache Spark is a lightning-fast cluster computing technology, designed for fast computation. It is based on Hadoop MapReduce and it extends the MapReduce model to efficiently use it for more types of computations, which includes interactive queries and stream processing. The main feature of Spark is its  in-memory cluster computing  that increases the processing speed of an application. Major issues with  Apache Hadoop . 1. Issue with Small Files 2. It has Slow Processing Speed 3. Only support for Batch Processing only 4. There is no support for Real-time Data Processing To overcome all these issues, Apache Spark comes into the picture . one more reason behind Evolution of Apache Spark is that there were many general purpose computin...
