How many tables are there in oracle apps

Any table that may be updated by a concurrent program also needs additional columns. The following table lists the concurrent processing columns used for Record History, the column attributes and descriptions, and the sources for the values of those columns. Some operations that must be done at commit time do not seem designed for a table handler.

For example, event handlers are preferred to table handlers for setting Record History information for a record, or determining a sequential number. This property classes sets the correct attributes for these fields, including the data type and width.

Never use Record History columns to qualify rows for processing. Never depend on these columns containing correct information. This section discusses the declarative constraints the Oracle database permits on tables, and when to use each feature with your Oracle E-Business Suite tables. For the most part, any constraint that is associated with a table should be duplicated in a form so that the user receives immediate feedback if the constraint is violated.

If you do create additional constraints, you may need to disable them before upgrading Oracle E-Business Suite. Use wherever appropriate. In general, do not use this feature due to potential locking problems with Oracle Forms. You may be able to use this feature with tables that are not used by forms for example, those used by batch programs , or tables that contain columns that are not maintained by forms.

For example, defaulting column values can make batch programs simpler. A unique key may contain NULLs, but the key is still required to be unique. Only fields that the user can enter should have a uniqueness check within the form; system-generated unique values should be derived from sequences which are guaranteed to be unique.

Use this feature to check if a column value is valid only in simple cases when the list of valid values is static and short i. This is not usually a concern, since Oracle E-Business Suite database triggers should rarely be disabled. Some triggers such as Alert events are disabled before an upgrade and re-enabled at the end of the upgrade. Cascade Delete does not work across distributed databases, so you should program cascade delete logic everywhere it is needed.

Within Oracle Forms, you cannot search using wildcards on any column of these types. Average freespace of all blocks on a freelist. Number of threads per instance for scanning the table. Number of instances across which the table is to be scanned. Indicates whether the table is to be cached in the buffer cache Y or not N. Sample size used in analyzing this table. Date on which this table was most recently analyzed. Indicates whether this table is partitioned. Can the current session only see data that it place in this object itself?

The default buffer pool for the object. Question and Answer. You Asked Tom Is there a limit either internal to Oracle or to its maintainability for the maximim number of tables a database can hold.

What the? This is one is right up there. My curiosity has got the better of me Stuart, what on earth are you modelling that could potentially required tables? I've ask a few people in our project team - no developer, DBA, designer or architect has ever come across such a design before Re: What the? Let me guess: there are 10, customers and someone decided to build a separate order table per customer? For performance reasons of course ;-.

Kashif, October 25, - am UTC. Perhaps it's no so strange after all? The schema that I have in mind which needs to hold so many tables is designed to store the survey responses as part of a all purpose campaign management system.

The questions asked in each survey are completely different and hence the responses from each survey comprise a logical table. I am wondering if it is sensible to hold the responses from each survey as a separate table many tables - high performance - or go for the generic few tables - poor performance database design.

October 25, - pm UTC. You have a survey, made up of questions, questions have one of 4 sets of optional attributes. A reader, October 25, - pm UTC. Haha, customer table for storing customer attributes.? What a great thinking. You must get Phd for Relational Database Management. Query: How can you say that performance 'ld be increase if you use separate table for separate case survey or whatever? A reader, October 28, - pm UTC. It's not that you make your administration simple.

Having that many tables for a an "Entity" called Survey is against the relational database design. By an Entity, you are dealing a problem of grouping of information that are related to a real life thing. For example Customer. It stores all the relevent attributes of a customer.

How would one build a code for an invoice, that has a customer attribute. Strange thinking. This gives you unrestricted access to the business group. But if you connect to an HR reporting user, your access is restricted according to the definition of your security profile.

The security profile list tables contain denormalized lists of people, positions, organizations and payrolls. Security profile lists are intersection tables between a security profile and secured tables, as follows:. They are also written to when some relevant business processes are performed through Oracle HR, for example, employee hire or transfer.

If people are being secured via the supervisor hierarchy and organizations, positions and payrolls are not secured, the security list tables mentioned above are not used, and the Security List Maintenance process need not be run. The list of visible people is derived dynamically based on the current user. This section describes how the processes work.

A role is a set of permissions that can be granted to Oracle users or to other roles. You initiate it from the Submit Requests window. You should run PERSLM periodically for example, nightly to refresh the security lists upon which the secure views are built.

Important: This process has the capability to run multi-threaded, allowing it to take advantage of the capabilities of your hardware. It builds the required security lists based on the restrictions defined for the security profiles being processed. For each security profile within the scope specified when the process is submitted, PERSLM performs the following steps:.

If the View All flag is Y, the process ends leaving all security lists empty for the specified security profile. If the View All Payrolls flag is Y, the process leaves the payroll list empty.

If the View All Organizations flag is Y, the process leaves the organization list empty. If this flag is N, the process builds a list of all organizations below the top one you specified for the organization hierarchy you chose on the Define Security Profile screen.

If the Include Top Organization flag is Y, the top organization you specified is included in the list. Any organizations specifically listed in the Define Security Profile window are included or excluded as specified. If the Exclude Business Group flag is N, the business group is included in the list to allow newly entered employees and applicants to be visible before they are assigned to an organization. If the View All Positions flag is Y, the process builds a list of all positions within the organizations on the organization list.

If this flag is N, the process builds a list of all positions below the top one you specified for the position hierarchy you chose on the Define Security Profile screen.

If the Include Top Position flag is Y, the top position you specified is included in the list. The list of positions is built up for all organizations on the organization list, or for all organizations if the View All Organizations flag is Y. The process creates person list information for all people within the specified scope, including terminated employees, applicants, and contingent workers.
