Using SQL and XQuery With the IBM DB2 Client:
The IBM DB2 Client is an administrator’s interface to a family of data management products from IBM. The product supports a variety of programming languages, including SQL and XQuery, and includes a GUI for administration.
It is a popular choice for many organizations, especially those looking to simplify the process of managing data.
DB2 is a family of data management products:
DB2 is a family of data-management products from IBM that provide SQL-based databases. Initially, DB2 was only available on IBM mainframes, but the company has brought DB2 to a variety of platforms.
This includes Linux, MS Windows servers, and OS/2. The company has also developed versions of DB2 for PDAs. In addition to SQL, DB2 supports XQuery. Its architecture is inspired by the IBM IMS, the company’s proprietary database management system.
DB2 is available in traditional product packaging and as a monthly subscription. IBM also offers Db2 in a Value Unit Edition, which enables customers to pay a one-time charge for the software.
DB2 is also the power behind IBM InfoSphere Warehouse, a data warehouse offering that offers a range of business intelligence (BI) capabilities.
The DB2 family of products from IBM includes a relational database management system and relational database servers. Initially, DB2 supported a relational database model, but as time went by, the company began expanding the database’s capabilities to support non-relational structures and object-relational models. DB2 is now available for most operating systems and cloud storage.
It supports SQL and XQuery IBM DB2 Client:
Using SQL and XQuery with DB2 is not a difficult task. The DB2 client provides many features that enable users to perform SQL and XML queries.
However, there are several limitations associated with XML and XQuery. If you want to use XQuery with DB2, you need to make sure that the server supports XML schema evolution. Currently, the DB2 client does not support schema evolution.
IBM Db2 Community Edition is free to use and provides a relational database management system and XML database features.
The Community Edition is limited to 16 GB of RAM and four CPU cores. Moreover, it does not support a large number of concurrent user connections. The Community Edition replaces the Db2 Express-C edition.
XQuery is an XML querying language designed by the World Wide Web Consortium for data management. It provides a set of functions for analyzing, storing, and querying XML data.
XQuery supports well-formed XML data stored in a column. You can also query the XML data by using SQL and XQuery.
It includes a GUI for administration:
IBM’s DB2 client software is a client-server database management system that is used for data management. It has a command-line interface (GUI), which provides an interface for administration.
It can also issue commands and support common network communication protocols, such as TCP and Named Pipe.
There are two versions of DB2 client software: free and commercial. Both versions support relational database management and XML databases. However, the free version is limited to four CPU cores and 16 GB of RAM. It also lacks Enterprise support and has no limits on the number of concurrent users or database size.
IBM is continuing to invest in the GUI for this client. The VSCode extension for z/OS will allow developers to access the DB2 GUI and develop applications.
VSCode is a cost-effective way to provide support for a graphical user interface. It also loads much faster than the IBM Data Studio tool.
