A materialized view is a database object that contains the results of a query. The FROM clause of the query can name tables, views, and other materialized views. Collectively these objects are called master tables (a replication term) or detail tables (a data warehousing term). This reference uses "master tables" for consistency. The databases containing the master tables are called the master databases. For help with specific options in creating a materialized view, see Create/Edit View, especially the View Information or Materialized View Properties pane.

To initiate profiling, right-click the name of the function or procedure in the Connections navigator hierarchy and select Profile, or click the Profile button on the PL/SQL source editor toolbar. After the function or procedure is run in profiling mode, the profiler reports are located at the Execution Profiles tab of the object viewer window. You can review subprogram-level execution summary information, such as:

The Pending Changes window is displayed if you click Versioning, then CVS, then Pending Changes, or when you initiate an action that changes the local source control status of a file. This window shows files that have been added, modified or removed (locally or remotely), files whose content conflicts with other versions of the same file files that have not been added to source control files that are being watched, and files for which editors have been obtained. You can use this information to detect conflicts and to resolve them where possible.

Enable Line Selection by Click-Dragging: If this option is checked, you can select consecutive lines in the editor by clicking in the gutter and dragging the cursor without releasing the mouse button.

A file currently being edited with its saved version: Place the focus on the current version open in the editor, then select the History tab in the editor window. The saved file opens side by side with the file in the editor buffer.

One file with another file outside the project: Place the focus on the file in the editor to be compared; from the main menu, choose File, then Compare With Other File; in the Select File to Compare With dialog, navigate to the file and click Open.

Add Template: Adds an empty row in the code template display. Enter an ID value, then move to the Template cell; you can enter template content in that cell, or click the ellipsis (...) button to open the code editor to enter the template content.

Prepended to All Identifier Names (Microsoft Access, Microsoft SQL Server, and Sybase Adaptive Server migrations only): A string to be added at the beginning of the name of migrated objects. For example, if you specify the string as XYZ_, and if a source table is named EMPLOYEES, the migrated table will be named XYZ_EMPLOYEES. (Be aware of any object name length restrictions if you use this option.)

Run CVS in Edit/Watch Mode: If this option is enabled, you coordinate access to files by declaring an editor for them through CVS, after which they may be modified. Only those files that you check out after changing this preference will be affected. If this option is disabled, the edit and watch commands on the Versioning menu are disabled.

Automatically Make Files Editable: If this option is enabled, an editor is automatically used on a data file when you start to change it. (If you edit a file unintentionally, immediately use Versioning, then Unedit to revert.)

Middleware is software that is used to bridge the gap between applications and other tools or databases. Middleware sits between an operating system and the applications that run on it. It is effectively software that provides a method of communication and data management between applications that would otherwise not have any way to exchange data -- such as with software tools and databases.

Middleware appears in many locations; however, organizations and developers make specific use of middleware to more efficiently build applications. Organizations that use multi-cloud and containerized environments will often also use middleware as a more cost-effective way to develop and scale applications.

A client can make a request with network-based interactions. That client is typically an application that resides on the front end, which is where the user interacts with software. Resources such as databases, message queues, NoSQL data stores and file servers are often referred to as being part of the back end. Middleware will sit between these ends.

The requested data can take on many different forms and may be stored in a variety of ways, such as coming from a file server, fetched from a message queue or preserved in a database. The role of middleware is to enable and ease access to those back-end resources. Middleware programs will typically provide a messaging service for applications to transfer data, such as simple object access protocol (SOAP), representational state transfer (REST) or JavaScript object notation (JSON).

Middleware serves a variety of functions. First, it manages connectivity to various back-end resources. A middleware component might create a connection pool to provide fast and efficient access to a popular back-end database. It can also create connections to message queues and topics. Furthermore, a piece of middleware software may manage connections to cloud-based resources, like the Amazon Simple Storage Service (Amazon S3).

Second, middleware software has the capacity to implement logic based on the request made by the client. For example, a middleware component might recognize that a client browser making a given request has the language header set to English, and, as a result, the queries it makes to the back end might be tweaked to return nothing but English-based results. Or, perhaps a server could identify the geographical location of the client making the request based on its IP address and return data to the client that prioritizes results that are located close by. The ability to take a request from the user, perform logic and then customize the results is an important job performed by middleware software.

Third, middleware plays an important role in concurrent processing, load balancing and transaction management. Middleware software typically has the capacity to scale vertically and horizontally to help distribute incoming client requests over multiple servers, virtual machines or availability zones of the cloud. Middleware software can also handle concurrency and transaction management issues, such as dealing with problems that arise when two or more clients attempt to access or update a given back-end resource at the same time.

Finally, middleware plays an important role in securing access to back-end resources. Middleware software has the ability to challenge clients; it requires both a secure connection -- using a technology like SSL -- and authentication -- using either a username and password combination or a digital certificate. This security information is then used to check if the client making the request has the authority to access the data in question. If the rights are affirmed, the data is sent from the middleware server to the client using a secure and encrypted connection.

Enterprise application integration middleware enables programmers to create business applications without having to custom-craft integrations for each new application. In this situation, middleware helps software and service components work together, providing a layer of functionality for data consistency and multi-enterprise or B2B integration.

Typically, integration middleware provides messaging services, so different applications can communicate using messaging frameworks like SOAP, web services, REST or JSON. Other middleware technologies used in this category include Object Request Brokers (ORB) and data representation technologies like XML.

Platform middleware supports software development and delivery by providing a runtime hosting environment, such as a container, for application program logic. Its primary components are in-memory and enterprise application servers, as well as web servers and content management. Platform middleware includes tools that support application development and delivery, such as web servers, application servers and content management systems.

Generally, embedded or external communications platform middleware will allow different communications tools to work together. These communications tools enable application and service interaction. Resource management services, such as Microsoft Azure Resource Manager, host application program logic at runtime -- another key function in platform middleware. Other components include Trusted Platform Modules (TPMs) and in-memory data grids (IMDGs).

Platform middleware products are also available as specific on-premises or cloud service tools, as well as multitool suites. On a cloud suite site, middleware as a service offers the runtime environment and an integrated set of platform tools.

Middleware programs come in on-premises software and cloud services; they can be used independently or together, depending on the use case. While cloud providers bundle middleware into cloud services suites -- such as middleware as a service (MWaaS) or integration platform as a service (iPaaS) -- many businesses may choose independent middleware products that fit their specific needs.

Middleware should be chosen by considering what an individual or organization is looking to achieve with it. For example, if middleware is needed for data management, then database middleware should be used; if middleware is needed for application services, then application server middleware should be used. The key idea is to find the right software according to the performance needed. 041b061a72
