• isPreparedForExecution function will check whether all PARAMETERS are assigned properly and QUERY is ready for execution. 
• On multiple navigations to the PAGE this query will not be executed multiple times.
• While EXECUTEQUERY function is used for executing the VO query so that it can fetch the data from database into VO cache.

• The root AM is loaded first and after that the MDS SUBSTITUTIONS are parsed.
• HENCE ROOT AM gets loaded even before the time the substitutions definition from MDS layer GET worked out. 
• Obviously, the root am cant SUBSTITUTE itself, hence it can’t be extended.

Customization is under direct user control. The user explicitly selects between CERTAIN options. Using customization a user can:

1. Altering the functionality of an application
2. Altering existing UI
3. Altering existing business LOGIC

EXTENSION is about extending the functionality of an application beyond what can be done through personalization. Using extension we can:

1. Add new functional flows
2. Extend or override existing business logic
3. CREATE New application/module
4. Create New PAGE
5. Create New attribute
6. Extend/Override defaults & validations

XML is a markup LANGUAGE for documents containing STRUCTURED information.

Structured information CONTAINS both content (words, pictures, etc.) and some INDICATION of what role that content plays (for example, content in a section heading has a different meaning from content in a footnote, which means something different than content in a figure CAPTION or content in a database table, etc.).

MDS is MetaData Service. When a web page is broken into small units like BUTTONS,FIELDS etc they are stored in a database. These are not stored as binary files but as data in tables. The data are present in JDR tables. MDS provides service to store & RETURN page DEFINITIONS. MDS collects those definitions in components/fields in a meaningful manner to build a page.

• Results based search GENERATES search items AUTOMATICALLY based on the COLUMNS on the results table.
• In Autocustomization search we NEED to set what all fields are required to display as a search CRITERIA.

• Inline LOVE is a lov which is used only for that PARTICULAR PAGE for which it was created and cannot be used by any other page.
• External lov is a COMMON lov which can be used by any page. It is a common component for any page to use it. It can be used by giving the full path of the lov in the properties section “External LOV” of the item.

A view LINK is an active link between view links. A view link can be CREATED by providing the source and destination views and source and destination ATTRIBUTES. There are TWO modes of View link operation that can be performed. A document and Master/Detail operation.

An association OBJECT is created where we link EO’s. For example TAKE the search page where we link the same EO to form a association between the manager and employee. EVERY employee should have a manager associated. But if it President then no there is no manager associated. This is a PERFECT example to UNDERSTAND the AO.

View object encapsulates the database QUERY. It is used for selecting data. It provides iteration over a query RESULT set.VO’s are PRIMARILY based on Eo’s. It can be used on multiple EO’s if the UI is for update. It provides a SINGLE point of contact for getting and setting entity object values. It can be LINKED together to form View Links.

It can be used on multiple EO’s if the UI is for update. It provides a single point of contact for getting and setting entity object values. It can be linked together to form View Links.

EO encapsulates the business logic and rules.EO’s are USED for INSERTING, Updating and Deleting DATA. This is used for validating across the applications. We can also link to other EO’s and CREATE a Association object.

Following are the components of BC4J:

1. ENTITY Object – EO encapsulates the business logic and rules. EO’s are used for Inserting, Updating and Deleting data from the database table. E0 is also used for VALIDATING the records across the applications.
2. VIEW Object – View object encapsulates the database query. It is used for selecting data. It provides iteration over a query result set. VO’s are primarily based on EO’s. It can be used on multiple EO’s if the UI is for update.
3. APPLICATION Module – Application Modules serve as containers for RELATED BC4J components. The pages are related by participating in the same task. It also defines the logical data model and business methods needed.

Following are the components of BC4J:

Business Components for JAVA is JDeveloper’s programming framework for building multitier database APPLICATIONS from reusable business components. These applications typically consist of:

1. A client-side user INTERFACE written in Java and/or HTML.
2. One or more business logic tier components that PROVIDE business logic and views of business objects.
3. Tables on the database SERVER that store the underlying data.

Controller is the java file and can be associated to a complete OAF PAGE or to a SPECIFIC region.

There are several tasks you will do routinely in your code.

1. Handle button press and other events
2. AUTOMATIC queries
3. Dynamic WHERE clauses
4. Commits
5. JSP Forwards
