Evaluation of Information Modelsta with the UPDATE command, and remove data with the DELETE command..We learned about the two forms of the INSERT command, with data explicitly included in the INSERT statement or INSERT from data SELECTed from another table. We saw how it is safer to use the longer form of the INSERT statement, whe

Knowledge Discovery and Data Minings and functions that we can use to refine queries and extract information..The procedural languages supported by PostgreSQL allow us to develop quite sophisticated server-side processing by writing procedures in PL/pgSQL, SQL, and other languages. This provides the opportunity for the database serve

Then we looked at database initialization and server control..Next, we discussed how we can manage the internals of a PostgreSQL server: creating databases, adding users, and managing how PostgreSQL places the physical files underlying the internal databases..Then we looked

We have used sample programs to make and close connections, and execute SQL statements to query, insert, or update rows in our database tables..We have considered problems of handling large volumes of da

Forest Fires And Remote Sensings concerned: the database-independent layer, DBI..Within the scope of DBI, we have the option of easily using other database back-ends with the same client code. There is also a lot of existing DBI extension code, in the form of DBIx modules, to make our programming job simpler..In the next chapter,
