This topic includes all the data types that are specific to the DBMSs supported in ArcGIS and what their equivalent native format is in ArcGIS.
Physical data types are dictated by the database driver set for the model. To understand more about the data types for your driver, see the documentation for its target database management system (DBMS). Change which set of physical data types is available Different d...
An RDBMS distinguishes between the following types of operations: 实际上,RDBMS将数据移入数据库、在数据库中存储和检索数据,以便应用程序能对其进行操作. RDBM区分为如下2种类型的操作: Logical operations (逻辑操作) In this case, an application specifies what content is required. 在这种情况下,由应用...

indicates that ArcGIS does not support that data type. When you specify a query, all columns that have an unknown data type must either be excluded or changed in the query to a data type that ArcGIS supports. SeeDBMS data types supported in ArcGISfor a list of supported data types per ...
The MSdbms_datatype_mapping table contains the allowable data type mappings from the data type in the source database management system (DBMS) to one or more specific data types in the destination DBMS. This table is stored in the msdb database and is used for heterogeneous database ...
Types of DBMS Now let’s look at the different types of database management systems. Relational Database Management Systems (RDBMS) Relational Database Management Systems are the most common type of DBMS. It stores data in the form of related tables and uses Structured Query Language (SQL) to...
large business and other organizations tend to build up many independent files containing related and even overlapping data, and their data-processing activities often require the linking of data from several files. Several different types of DBMS have been developed to support these requirements: flat...
Java Database Connectivity (JDBC) is a Java standard that provides the interface to connect Java applications to relational databases. In addition to supporting the standard JDBC application programming interfaces (APIs), Oracle JDBC also provides extensions to support Oracle-specific data types and enh...
