no they did not

I don't know, that's why I'm asking.

Data in a database table can be inserted by the help of Data Manipulation Language, by writing query in language like Sql.

What are the three most common forms of data warehouses? is a smaller form of a data warehouse that is often used by a single department or function. An independent data mart is a tiny warehouse that is built for a strategic business unit (SBU) or a department, but it does not have a central data source (EDW).

Okay. The previous answer was Preview. I am currently in Microsoft Access class and the actual answer, trust me on this, is Design.

It shouldn't let you leave the primary key blank. The primary key is a means of identifying a unique record.

Yes you can. You can create queries that do calculations. You can write code for programs to do calculations in a database. Doing calculations is a significant element of what you do with a database, so yes you can do them within a database.

Redundancy is data that is not needed or no longer needed. Inconsistency is where you have different data for what should be the same thing, as a result of one piece of data having a few copies and not all of them being updated. So if someone's address is on a system several times, and then their address changes, but it is only updated in some of those places, then the person will have both their old and new address on the system. The data is not consistent then. To avoid this data should be only stored once and everyone that needs it looks at the one set, rather than each having their own copy.

A user of a relational database refers to a field as a column in a table. This column represents a specific attribute or data type within the database table. By interacting with fields, users can query, update, and retrieve specific information stored in the database.

The DROP table command of SQL lets you drop a table from database . The database requires you to empty a table before you eliminate from the database. But there is a condition for dropping a table ; it must be an empty table. syntax: 1st - delete from table-name; 2nd- drop table table-name;

The DROP command allows you to delete things such as tables or indexes.

In a Database Management System (DBMS), columns represent the attributes or fields of a table that define the data structure. Each column has a specific data type (e.g., integer, string, date) and holds values for that attribute across all records (rows) in the table. Columns help organize and categorize data, enabling efficient data retrieval and manipulation through queries. They are essential for defining the schema of the database.

. Failover Cluster protects the instance, while DB

Mirroring protects one or more DBs.

2. failover clustering required dedicated H/W, while DB

Mirroring is not required dedicated h/w

1. Database it's case sensitive

2. If database was cape chart using particular size must be maintain

there are four alternative stratagies regarding the placement of data.centerlized,fragmented, completc replication and selective replication.

The queue is a linear data structure where operations od insertion and deletion are performed at separate ends also known as front and rear. Queue is a FIFO structure that is first in first out. Whenever a new item is added to queue, rear pointer is used. and the front pointer is used when an item is deleted from the queue.

Deciding between SAP and Oracle as the "best" depends on various factors, including the specific needs and circumstances of an organization. Both SAP and Oracle offer powerful enterprise software solutions, but they have differences in terms of product offerings, strengths, and weaknesses. Here are some considerations to help you decide:

SAP:

Strength in ERP: SAP is renowned for its Enterprise Resource Planning (ERP) software, such as SAP S/4HANA. It excels in providing integrated solutions for finance, supply chain, human resources, and other core business functions.

Wide Product Portfolio: SAP offers a broad range of software solutions beyond ERP, including customer relationship management (CRM), analytics, and cloud services.

Cloud Transformation: SAP has made significant strides in cloud computing with SAP Cloud Platform and SAP SuccessFactors for human capital management. It provides options for both on-premises and cloud deployments.

Industry Focus: SAP has a strong presence in various industries, including manufacturing, retail, utilities, and healthcare.

Global Reach: SAP has a global customer base and support network, making it suitable for multinational organizations.

Oracle:

Diverse Product Ecosystem: Oracle offers a wide array of software products, including databases, cloud services, ERP (Oracle Fusion), CRM (Oracle CX), and more.

Database Expertise: Oracle is renowned for its database technology and is widely used in enterprises worldwide.

Cloud Services: Oracle Cloud provides robust cloud infrastructure and application services, including database as a service (DBaaS), infrastructure as a service (IaaS), and platform as a service (PaaS).

Industry Solutions: Oracle offers industry-specific solutions tailored to sectors like hospitality, telecommunications, and financial services.

Integration Capabilities: Oracle's middleware and integration solutions enable businesses to connect diverse systems and applications.

When choosing between SAP and Oracle, consider the following:

Specific Needs: Assess your organization's specific requirements, industry, and size to determine which vendor aligns better with your needs.

Budget: Evaluate the total cost of ownership, including licensing, implementation, and maintenance costs.

Legacy Systems: Consider your existing systems and whether integration with them is critical.

Scalability: Assess whether the solution can scale with your organization's growth.

Support and Maintenance: Investigate the availability and quality of support and updates from the vendor.

User Experience: Consider the user-friendliness and ease of adoption for your team.

Ultimately, there is no one-size-fits-all answer, and the "best" choice depends on your organization's unique circumstances. Many organizations consult with IT experts or conduct thorough evaluations to make an informed decision. Both SAP and Oracle have a strong presence in the enterprise software market, and each has its strengths and weaknesses.

what are the consequences of changing a field size

It is the same difference between an OR Boolean and AND Boolean. In an OR query, you are looking for something that matches one of several possible values, while in an AND query, you are looking for something that matches all of several possible values.

-- Find the first name of anyone in the USA, or have a last name starting with A.

SELECT FirstName FROM Contacts WHERE Country = 'USA' OR LastName LIKE 'A%'

-- Find the first name of anyone in the USA that also has a last name starting with A

SELECT FirstName FROM Contacts WHERE Country = 'USA' AND LastName LIKE 'A%'

The difference between these two is that the first one will return people outside the USA if their last name starts with an A, while in the second query, only people inside the USA with the last name starting with A will be returned.

AND will always return the same or fewer values than OR.
