Required courses:

CDS 120 Introduction to Programming with PythonThis course introduces the fundamentals of computer programming using the Python programming language. Topics include: variables, types, and assignment; iteration and conditional execution; functions, modules, and structured design; complex types and data structures. 3 credits. |

CDS 121 DataAn introduction to the principles, techniques, and tools used in the creation, organization, and manipulation of data in a modern computing environment. Topics will include: computer memory organization and binary data formats; files and file systems; relational databases; modern "noSQL" datastores. Students will be introduced to some elementary programming in a language like Python. Prerequisite or Corequisite: CDS 120 3 credits. |

CDS 241 Programming IIA continuation of CDS 142, students will extend and deepen their understanding of programming using Java. The course will cover three main topics: Object-oriented software organization; design and implementation of elementary data structures and algorithms; the mathematical tools and techniques required for complexity analysis. Prerequisite: CDS 120, or by permission of the instructor. 3 credits. |

CDS 242 Algorithms and Data StructuresA study of the design, analysis, and application of data structures and algorithms. Trees, graphs, heaps, hash tables, and other structures will be considered. Several mathematical techniques (e.g., complexity analysis, recurrence relations, and induction) will be studied and applied to understanding these algorithms and structures. The impact of modern computer hardware, especially caches and parallelism on the design and performance of data structures and algorithms will be considered. Prerequisite: CDS 241; MAS 111 or MAS 161. 3 credits. |

CDS 343 Data Analysis and VisualizationThis course will explore how to design and create data visualizations based on the data available and the tasks to be achieved. This process includes data modeling, data processing (such as aggregation, filtering, and cleaning), mapping data attributes to graphical attributes, and strategic visual encoding based on known properties of visual perception as well as the task(s) at hand. Students will also learn to evaluate the effectiveness of visualization designs and conduct exploratory data analysis using visualization. Prerequisite: CDS 121 and CDS 242. 3 credits. |

CDS 362 Distributed SystemsThis course examines the design of modern, distributed software applications. Client/Server models (from RPC designs to modern REST-based architectures) will be the focus, though other distribution models will be considered. Scalability, security, and other fundamental issues will be addressed. Students will design and implement a service and a mobile front end to that service as a semester-long team project. Prerequisite: CDS 242 and MAS 112. 3 credits. |
