Database Management System (DBMS Notes) is semester 5 subject of final year of computer engineering in Mumbai University. Prerequisite for studying this subject are Basic knowledge of Data structure.

Course objectives for subject Database Management System Learn and practice data modelling using the entity-relationship and developing database designs. Understand the use of Structured Query Language (SQL) and learn SQL syntax. Apply normalization techniques to normalize the database. Understand the needs of database processing and learn techniques for controlling the consequences of concurrent data access. Course outcomes for subject Database Management System On successful completion of course learner will be able to: Understand the fundamentals of a database systems. Design and draw ER and EER diagram for the real life problem. Convert conceptual model to relational model and formulate relational algebra queries.Design and querying database using SQL. Analyze and apply concepts of normalization to relational database design. Understand the concept of transaction, concurrency and recovery.

A database is an organized collection of data, generally stored and accessed electronically from a computer system. Where databases are more complex they are often developed using formal design and modeling techniques. The database management system (DBMS) is the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS software additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a “database system”. Often the term “database” is also used to loosely refer to any of the DBMS, the database system or an application associated with the database. Computer scientists may classify database-management systems according to the database models that they support. Relational databases became dominant in the 1980s. These model data as rows and columns in a series of tables, and the vast majority use SQL for writing and querying data. In the 2000s, non-relational databases became popular, referred to as NoSQL because they use different query languages.
