**What This Document Is**
These are lecture notes taken during the first exam review sessions for MISM 2301, Management Information Systems at Northeastern University, covering material from September and October 2015. The notes focus on the different types of software—system, general purpose, and application-specific—and the considerations companies make when selecting and implementing them. A significant portion also details the evolution of databases from flat files to relational databases, including key concepts like tables, records, primary keys, foreign keys, and metadata. Finally, the notes introduce data communication standards like EDI, XML, ETL, and RSS.
**Why This Document Matters**
This document is valuable for students enrolled in MISM 2301 preparing for Exam One. It provides a condensed review of core concepts discussed in lectures, offering a quick reference point for understanding the foundational elements of information systems and database management. It’s most useful when used *in conjunction with* course readings and full lecture recordings.
**Common Limitations or Challenges**
These notes are a *record* of lectures, not a replacement for them. They are not a comprehensive textbook and lack the detailed explanations and examples provided in class. The notes are also specific to the 2015 iteration of the course and may not reflect current examples or emphases. They do not include practice questions or exam solutions.
