How is the co citation frequency of a scientific paper determined?
The co-citation frequency of two scientific papers can be determined by comparing lists of citing documents in the Science Citation Index and counting identical entries. Networks of co-cited papers can be generated for specific scientific specialties, and an example is drawn from the literature of particle physics.

How to create a relational database using MySQL?
This is part 2 of a 3-part series taking you through the process of designing, coding, implementing and querying a relational database, starting from zero.

Why are contraints added to a table in RDBMS?
Contraints specify rules for data in a table, and will constrain what the RDBMS will allow us to do to that particular attribute. We have added NOT NULL to first_name, last_name and language_1 — this means that the table will not accept a record where any of those attributes are set to NULL.
What kind of data can be stored in MySQL?
MySQL supports a wide range of data types, from simple integers and strings to BLOBs and JSONs. We will just be using a small subset of these in our database. INT — this is an integer, a whole number.
