Microsoft Access

Just like Cascade Update Related Fields updates any record you change to the other table you have made a relationship with, Delete does the same thing! Delete one record and the other table which you have also made a relationship with will be deleted aswell.

Yes, you can actually create simple spreadsheets in Word. By using tables you can lay out numbers and use some simple formulas to do calculations for the rows and columns, like in a spreadsheet. However, Word is very limited in what it can do in that regard, so people would not really use it to do that. A lot of people don't even know it can do that. What people do is use an actual spreadsheet application, like Excel, to do their spreadsheets. If necessary, they can copy some completed calculations into Word, where it will appear as a table.

To create a database you need to name a file and add that to Microsoft excel :) hope that helps :)

Referential Integrity is a set of rules that a DBMS (Database management system) follows to ensure that there are matching values in the common field used to create the relationship between related tables and that protects the data in related tables to make sure that data is not accidentally deleted or changed.

Use the import function and select the spreadsheet you wish to bring in. You can create a new table in Access, or you can make sure the column headings match up and bring it into existing tables.

A text field can contain both numbers and text, so that is what you would use.

No it is not. However, there are a lot of things that both a database and a spreadsheet can do, so Access does have some capabilities to do what a spreadsheet can. Spreadsheets focus on numeric analysis and manpulation, so mostly concentrate on numbers. Databases deal with processing lists of data, some of which would be numeric, but it works with a lot of other kinds of data. Microsoft Access is a database and that is what it is designed to be, so it is not a spreadsheet.

A database record is a row of data in a database table consisting of a single value from each column of data in the table. The data in the columns in a table are all of the same type of data, whereas the rows represent a given instance. Example Table: ========================================================== Column Names: ID FirstName LastName BirthDate ========================================================== 1 George Gray 1/6/1960 2 Thomas Green 2/29/2000 3 Cynthia Black 5/30/1976 ========================================================== For the given table above, an example of a column of data would be FirstName. All the values in that column are first names. An example record (or row) would be the record with ID = 2 which represents the record for Thomas Green and contains each field from that row. Properly designed relational databases use "primary keys" to uniquely identify records in a database. The value (or values) that compose the key must uniquely identify the entire row and only that entire row in that table. That primary key can then appear in another table to represent a relationship between that table and another table. In the example above, the ID column would serve as the primary key for the table.

A database.

A table is really just one part of a database. The database consists of other things like the queries and reports. In general we do specifically think of the tables as being the database as that is where the data is stored and tables are central to everything else. As there can be multiple tables and other things as part of the system the term database is used to cover them all as one or as what is called a database management system.

My sql, Microsoft sql , Microsoft Access, dBase, Filemaker pro are the examples for dbms and oracle and sql server are the examples for rdbms

To be totally accurate, a table holds data, not information. The answer to your question is a record. Data is the individual facts like a date of birth or a name etc. Information is derived from data. So for example, while you may have a list of dates of birth, nowhere does it specifically tell you something like how many people were born in April or who is the second oldest person. However you can write queries and do other things to find those things out, and that is information.

The data sheet view in Microsoft SharePoint is a useful tool for quickly editing several list items. It functions similar to an Excel spreadsheet and can be exported to or imported from an Excel spreadsheet.

At the top of the field list in the table that you see in the top half of the query design, there is a star. This represents all fields in the table. Double clicking it will add all fields. However, doing this does not actually show all the fields individually in the Design grid. You will see the name of the table followed by a dot and a star in the first column. Running the query will display all the fields. If you want to individually see all the fields, you can add them in a different way. Click on the first field in the list and then pressing the Shift key, click on the last field. Now all of them will be selected. Then just drag them down to the grid and each field will automatically be put into its own column.

A Relational Database is a Database in which the data it contains is stored in separate Tables, with these tables related to each other. These Tables each hold information on logical groups of Data. For example a company's business data may be stored in different independent but inter-related Tables. They may have a list of Products and a list of Suppliers for those Products. The company would want to know which company supplies each product. For each supplier they would want to know their Name, Address, Contact Details etc. All the data could be put in one table.

However if one supplier supplies 100 different products and all their details are stored for each product this will mean a lot of repeated data and make the table quite large. Also, if any of the suppliers details change, this amendment will have to be made for each product's record. This obviously means a lot more work. There is also the possibility that this change may not be made in every record that requires it and inconsistencies will result in the database. The database may have different addresses or phone numbers stored for the one supplier. The solution is to have one table which stores all the product details and another table that stores the supplier details. In order to make sure that each product is still associated with a supplier a Relationship is set up between the two tables. This is done by having one field common to both Tables. Both fields must be of the same type and size, though its name can be different.

Each Supplier's full details now only appear once in the database, in the Suppliers Table, regardless of the amount of products they supply. Each Product is related to a particular supplier by having the relevant Suppliers Code included in the Products Table. This stops us having to store all the details of the Supplier for each Product as when all the data was being stored in the same table.

As one supplier can have many products and as the supplier appears once in the database, this is an example of a one to many relationship. There are also what are called one to one relationships, where each item is related to only one other and there are many to many relationships, where many things can be related to many others. An example is a music collection where you have many CDs and there are many songs. Each CD has many songs and each song could be on more than one CD.

I have been using the Open Office database from Novel, it is free and handles much more than MS Access. To me the major advantage is that it also reads and writes just about every data format around - even many of the Microsoft Office formats no longer supported my MS Office 2007. I have a lot of old data (try Word Star 1985), Open Office reads it with no problem!

Use the table wizard or design view.

Forms allow you to display data in a more presentable form than a datasheet can. It can allow you to see all the fields at once, or just some of the fields. It can also allow you to generate other data from the existing data, like showing a calculation from figures on the form. Forms allow more functionality by having controls on them, such as buttons. They can link into queries. They can set up subforms for presenting data in relationships. There are many other things they can do, so they are very useful for databases.

Access forms are much like paper forms; you can use them to enter, edit, or display data. They are based on tables. When using a form, you can choose the format, the arrangement, and which fields you want to display. The "form view" tells access to show you the form created for you to do that above tasks

Recursive queries When a client system sends a recursive query to a local name server, that local name server must return the IP address for the friendly name entered, indicate that it can't find an address, or return an error saying that the requested address does not exist. Name servers do not refer the client system requesting a recursive query to other DNS servers. When answering recursive queries, the originating client does not receive address information directly from any DNS server other than the local name server. Typically, the local name server will first check DNS data from its own boot file, cache, database, or reverse lookup file. If the server is unsuccessful in obtaining the answer from those local sources, it may contact other DNS servers for assistance using iterative queries and then pass the information it receives back to the client that originated the name resolution request. Iterative queries In iterative queries, name servers return the best information they have. Although a DNS server may not know the IP address for a given friendly name, it might know the IP address of another name server likely to have the IP address being sought, so it sends that information back. The response to an iterative query can be likened to a DNS server saying, "I don't have the IP address you seek, but the name server at 10.1.2.3 can tell you." The process is straightforward. Here's one example in which a local name server uses iterative queries to resolve an address for a client: The local name server receives a name resolution request from a client system for a friendly name (such as www.techrepublic.com). The local name server checks its records. If it finds the address, it returns it to the client. If no address is found, the local name server proceeds to the next step. The local name server sends an iterative request to the root (the "." in .com) name server. The root name server provides the local name server with the address for the top-level domain (.com, .net, etc.) server. The local name server sends an iterative query to the top-level domain server. The top-level domain server replies with the IP address of the name server that manages the friendly name's domain (such as techrepublic.com). The local name server sends an iterative request to the friendly name's domain name server. The friendly name's domain name server provides the IP address for the friendly name (www.techrepublic.com) being sought. The local name server passes that IP address to the client. It seems complicated, but the process completes in a matter of moments. Or, if an address isn't found, a 404 error message is returned to the client.

It's a database application which allows you to store, organise and retrieve information in a structured way.

It is a text type. There are a number of reasons why you do not use a number type. Most phone numbers in their full form start with a zero. If entered into a number field, the zero would be dropped. Number fields do not allow spaces or other characters, such as hyphens or brackets, that are often used when entering phone numbers. Although they are numbers, you never do calculations on phone numbers, like adding or multiplying or getting averages. So no numerical operations are carried out.
