If the user interface has free-text fields for entering the region and the industry, it makes sense to store them as plain strings. g. if there are several cities with the same name, The name is stored only in one place, so it is easy to update across the board if it ever needs to be changed (for example, change of a city name due to political events), When the site is translated into other languages, the standardized lists can be localized, and so the region and industry can be displayed in the viewer’s language, Better search—for example, a search for philanthropists in the state of Washington can match this profile, because the list of regions can include the fact that Seattle is in Washington.
You can read a particular row by designating some columns as a key, and matching on those.  In a relational database, the query optimizer automatically decides which parts of the query to execute in which order, and which indexes to use. Those choices are effectively the “access path”, but the big difference is that they are made automatically the query optimizer, not by the application developer, so we rarely need to think about them. If you want to query your data in new ways, you can just declare a new index, and queries will automatically use whichever indexes are most appropriate.
Query Languages for Data When the relational model was introduced, it included a new way of querying data: it used a declarative query language, whereas IMS and CODASYL queried the database using imperative code. What does that mean? Many commonly-used programming languages are imperative. push(animals[i]); } } return sharks; } In the relational algebra, you would instead write: sharks = σfamily = “Lamniformes” (animals) 45 where σ (the Greek letter sigma) is the selection operator, returning only those animals that match the condition family = “Lamniformes”.
