The SYSCAT.COLUMNS View (DB2) (continued)
There is considerable variation in the way that the column definition is provided by the system catalogs of various DBMS brands. For comparison, Table 16-5 shows the definition of the Informix Universal Server SYSCOLUMNS table. Some of the differences between the column information in the tables are simply matters of style: I The names of the columns in the two tables are completely different, even when they contain similar data. I The DB2 catalog uses a combination of the schema name and table name to identify the table containing a given column; the Informix catalog uses an internal table-id number, which is a foreign key to its SYSTABLES table. I The DB2 specifies data types in text form (for example, CHARACTER); the Informix catalog uses integer data type codes. Other differences reflect the different capabilities provided by the two DBMS brands: I DB2 allows you to specify up to 254 characters of remarks about each column; Informix does not provide this feature. I The Informix system table keeps track of the minimum and maximum length of actual data values stored in a variable-length column; this information is not available directly from the DB2 system catalog.

View Information
The definitions of the views in a database are usually stored by the DBMS in the system catalog. The DB2 catalog contains two system tables that keep track of views. The SYSCAT.VIEWS table, described in Table 16-6, contains the SQL text definition of each view. If the definition exceeds 3600 characters, it is stored in multiple rows, with sequence numbers 1, 2, 3, and so on. The DB2 SYSCAT.VIEWDEP table, described in Table 16-7, shows how each view depends on other tables or views. There is one row in the table for each dependency, so a view with three source tables will be represented by three rows. Using these two tables, you can see the definitions of the views in the database and quickly determine which tables in the database serve as the source tables for a view. As with many mainstream DBMS products, information about views is tightly linked to the information about tables in the DB2 catalog. This means there is often more than one way to find the answer to a catalog inquiry. For example, here is a direct query
