Explain the different object available in Microsoft Access?
Choosing Field Names Microsoft Access gives you lots of flexibility when it comes to naming your fields. A field name can be up to 64 characters long, and can include any combination of letters, numbers, spaces, and special characters except a period (.), an exclamation point (!), an accent grave ('), and brackets ([ ]); however, the name cannot begin with a space, and cannot include control characters (ANSI values 0 through 31).
In general, you should give your fields meaningful names and should use the same name throughout for a field that occurs in more than one table. You should avoid using field names that might also match any name interval to Microsoft Access or Visual Basic. For example, all objects have a Name property, so it's a good idea to qualify a field containing a name by calling it CustomerName or ClubName. You should also avoid names that are the same as built-in functions, such as Date, Time, Now, or Space. See Microsoft Access help for a list of all built-in functions names. For character data,
You should normally select the Text data type. You can control the maximum length of a Text field by using a field property. Use the Memo data type only for long strings of text that might exceed 255 characters or that might contain formatting characters such as tabs or line endings (carriage returns). When you select the Number data type,
You should think carefully about what you enter as the Field Size property because this property choice will affect precision as well as length. (For example, integer numbers do not have decimals.) The Date/Time data type,
Useful for calendar or clock data and has the added benefits of allowing calculations in minutes, seconds, hours, days, months, or years. For example, you can find out the differences in days between two Date/Time values.
Use the Date/Time data type to store any date, time, or date and time value. Currency data type,
For storing money values. Currency has the precision of integers, but with a fixed number of decimal places. When you need to store a precise fractional number that's not money, use the Number data type and choose the Decimal field size. The AutoNumber data type,
Specifically designed for automatic generation of primary key values. Depending on the Field Size and New Values properties you choose for an AutoNumber field, you can have Access create a sequential or random long integer. You can include only one field using the AutoNumber data type. Use the Yes/No data type,
Hold Boolean (true or false) values. This data type is particularly useful for flagging accounts paid or not paid or orders filled or not filled. The OLE Object data type allows you to store complex data, such as pictures, graphs, or sounds that can be maintained by a dynamic link to another Window-based application. For example, Access can store and allow you to edit a Microsoft Word document, a Microsoft Excel spreadsheet, a Microsoft PowerPoint presentation slide, a sound file (wav), a video file (avi), or picture created using the Paint or Draw application. The Hyperlink data type lets you store a simple or complex "link" to an external file or document. This link can contain a Uniform Resource Locator (URL) that points to a location on the World Wide Web or on a local intranet. It can also contain the Universal Naming Convention (UNC) name of a file on a server on your local area network (LAN) or on your local computer drives. The link can point to a file that is in Hypertext Markup Language (HTML) or in a format that is supported by an ActiveX application on your computer.

How many table views are available in MS Access?
There are two main view
Datasheet View
AND
Desing View
OTHER'S
Pivot Table View
Pivot Chart View
A shop will use a database to keep an inventory of stock on the shelves. When stock levels reaches a certain point, automatic reordering may take place. Price control should also be enabled within the database.
Does form view displays a single record at a time?
to display only the records that meet the requirements in the access data what do you do.
What is A field that uniquely identifies a particular record in a table called?
A field that uniquely identifies a particular record in a table is called a primary key. The field or fields on which records are sorted is called the sort key.
What are the object-naming rules in ms-access?
Here are the "Object Naming Rules," as provided by the Microsoft Access Help File: --------------------------------------… Guidelines for naming fields, controls, and objects Names of fields, controls, and objects in Microsoft Access: Can be up to 64 characters long. Can include any combination of letters, numbers, spaces, and special characters except a period (.), an exclamation point (!), an accent grave (`), and brackets ([ ]). Can't begin with leading spaces. Can't include control characters (ASCII values 0 through 31). Can't include a double quotation mark (") in table, view, or stored procedure names in a Microsoft Access project. Although you can include spaces in field, control, and object names, most examples in the Microsoft Access documentation show field and control names without spaces because spaces in names can produce naming conflicts in Visual Basic for Applications in some circumstances. When you name a field, control, or object, it's a good idea to make sure the name doesn't duplicate the name of a property or other element used by Microsoft Access; otherwise, your database can produce unexpected behavior in some circumstances. For example, if you refer to the value of a field called Name in a table NameInfo using the syntax NameInfo.Name, Microsoft Access displays the value of the table's Name property rather than the value of the Name field. Another way to avoid unexpected results is to always use the ! operator instead of the . (dot) operator to refer to the value of a field, control, or object. For example, the following identifier explicitly refers to the value of the Name field rather than the Name property: [NameInfo]![Name] --------------------------------------…
How can you create table using datasheet view?
When you open Access, Select NEW. The New tab provides several ways that you can create a new database including "TABLE View" which then looks like a datasheet
What does the mean in Microsoft Access?
The * symbol is a universal wildcard symbol. In the Access Query By Example Design Pane, the * represents all fields in the table or query.
Direct access.
AS
It is a query that returns the data in a tabular form, similar to a pivot table in a spreadsheet. There are headings across the top and down the side. A typical example would be counting how many staff in each department are male and female. You could have the headings of the departments down the side and the headings for male and female across the top. Then there would be a total for each gender in each department.
What impact did the first computer have on society?
Personal computers have really changed the way we communicate with one another. Just look at these social media websites like Facebook, for example, where one can message another without leaving the comfort of their own home and instantly too. Personal computers simplify everything in our lives. Typing documents, finding calculations, watching movies, playing games. All of it is done on a personal computer.
How do you Access MS Access from C?
The following example creates an OracleConnection and sets some of its properties in the connection string. * ** Syntax based on .NET Framework version 1.1 ** #using #using #using using namespace System; using namespace System::Data; using namespace System::Data::OracleClient; __gc class COracleConnection
{ public:
void CreateOracleConnection( )
{ String* myConnString Oracle8i;Integrated Security new OracleConnection( myConnString ); myConnection->Open( ); MessageBox::Show( String::Format( S"ServerVersion: {0}\nDataSource:{1}", myConnection->ServerVersion, myConnection->DataSource ) ); myConnection->Close(); } }; // This is the entry point for this application #ifdef _UNICODE int wmain( void ) #else int main( void ) #endif { COracleConnection *pCOracleConnection = new COracleConnection(); pCOracleConnection->CreateOracleConnection( ); return 0; } You will use Oracle's API. Its called OCI for Oracle Call Interface -- use Google for details about its usage. You can also use OTL, which is the Oracle Template Library. Its much easier to use than OCI. Additionally, you can use embedded sql and precompile this code into pure C using the Oracle Pro*C/C++ precompiler. Sample code exists in ORACLE_HOME/precomp/demo/proc and ORACLE_HOME/rdbms/demo. As Oracle is the largest database company in the world with the largest market share of enterprise s/w, you can bet there is code all over the internet to do what you want to do. Check the forums at otn.oracle.com, google (or other search engine), or asktom.oracle.com. Answer You can also use library such as OCILIB (wraper for OCI) and Libsqlora. The other solution is use UnixODBC for unix programming environtment. Visit www.alldatabaseprogramming.blogspot.com or www.gtkinaction.blogspot.com for further information.
Which data type stores only one of two values?
In Java, such a data type is called boolean. In other programming languages it may be known by different names, including variations of "boolean" such as "bool", and "logical".
What is access management system?
Access Management is concerned with the management of people's rights of access to information, and as such has common purpose not only with Information Security Management, but also with Availability Management, giving practical effect to the policies and requirements of both processes. Its goal is to ensure that the confidentiality, integrity and availability of information are effectively managed across the organization. Data and information must not only be protected against unauthorized access and the possibility of it being stolen or changed. It must also be readily available to those who are authorized to access it.
A key part of Access Management is the management of people's rights to access information and services. People who have the right, in terms of business policy and need, to access information should have that right implemented through access controls. These rights must be consistent with relevant legislation such as data protection legislation, and must be kept under review and changed or revoked when a person's status changes within the organization, or when a material risk is identified.
Difference between design view and wizard?
In design view you have to do all the work to create something yourself, like design view for tables or forms or queries or reports. This is good if you know what you are doing and are experienced. A wizard will quickly create a basic item. It is fast, but it does not necessarily give you all you need. Some users will use the wizard to create the basic structure and then use design view to add in the specific things they need to do what they want. The wizards are good for forms and reports, but you are more likely to use design view for tables and queries.
What is Microsoft's access database tool used for?
Microsoft's Access database is used for gathering and understanding information such as your phone numbers, inventory, guest lists, things you are tracking in order to provide a convenient way to enter, navigate, and report your data.
How do I close a database without exiting Access?
Click the X in the top corner of the Database Window. You could also press the Ctrl - W key combination.
What are the four filters used in access?
Four types of filters are available in Access: Filter By Selection, Common Filters, Filter By Form, and Advanced Filter/Sort.
When you perform certain tasks Access displays tabs called what?
Access displays tabs called_____ when you perform certain tasks.
What connects the records in access in separate tables?
Joins or relationships. This is done through having values that appear in both tables. A record in one table can then be linked to a corresponding record in another table. It can also be done through queries.
