I am still new at database design, and cant quite come to terms with my project and access way of doing things.
I have to keep a register of people who participate in projects. The projects can be of two different kinds. BUT (here comes the tricky part) The projects are being evaluated on three different indicators, with each one of these having 4 measurements, in the range of 4-0. That was a quick introduction. Now let me break it down in parts.
The people:
I have made a Uniqe identifier (Social Security number (PK))
First Name
Last Name
Department (This can be 4 different departsment) made a drop-down menu type.
The Projects:
Unique identifier (Project ID (PK))
Social Security number
Project Type
Start date
End date
Project type:
Unique identifier (TypeID (PK)
Project type (Cti / Regular)
How might i design this the best way, so i can combine the people with the projects there on. And which type.
There can only be one person, but he can be on many projects. These projects can vary in type. My problem is ensuring there connected proberly.
Furthermore, once the basic design is made i need to make evaluations based on their performance if they are on the projecttype "Cti".
here i need 3 x this:
Evaluations:
Objective (range 0-4)
Baseline reading (range 0-4)
Midway reading (range 0-4)
End reading (0-4)
Success = Yes/NO (here i will do a End reading <= Objective formula).
That was a rather long list, but i have sat working on this in three whole days, and im getting a little fed up with not knowing up-and-down.
I am in the beginning of setting up a database and have NOT messed with multiple tables. I just want to make sure that I am setting up the tables as well as the relationships correctly.Here is what I currently have, 4 tables and they are named. Employee, phone, radio and spotter. Employee table is where my primary key is located and I currently have a 1-to-many relationship between Employee and the others.
What I want to be able to do is to store information in the multiple tables from 1 form, which I don't think will be an issue and then at a later date be able to pull up information. EX.Thus being able to skip anything being put into the spotter table. Then at a later date be able to pull up only the select information I originally put it?
tblFarParagraph FarParaID (PK) FarNumID (fk from tblFAR) FarParaTitle FarParaText
tblAC ACNumID (PK) ACNumber ACTitle
tblACParagraph ACParaID (PK) ACNumID (fk from tblAC) ACParaTitle ACParaText
1.Each FAR contains Many FarParagraph 1 to Many 2.Each AC contains Many ACParagraph 1 to Many 3.Each FarRParagraph contains Many ACParagraph AND Each ACParagraph contains Many FarParagraph Many to Many
What I’m trying to do:
FAR Chapter 1 Paragraph a – Relates to AC Chapter 4 paragraph a1 Paragraph b – Relates to AC Chapter 4 paragraph a Paragraph c – Relates to AC chapter 6 paragraph b
AC Chapter 4 Paragraph a – Relates to FAR Chapter 1 paragraph b Paragraph a1 – Relates to FAR Chapter 1 paragraph a Paragraph a2 – Relates to FAR Chapter 6 paragraph c Paragraph b – Relates to FAR Chapter 8 paragraph d
I’m not sure if my design is correct for what I want. BTW -- AN "AC" and "FAR" are just a type of document. Thanks Paul
I'm having some trouble getting my information that I input on my form to store in my correct table. I will attach my DB so you can take a look at what I have thus far.
Here is what I am wanting to do:
I have TblEmployee, TblEquipment and TblJunction and FrmTracking and FrmUpdate
I input the bulk of my information thru FrmTracking, my trouble is I can not seem to get the information that I input in my FrmTracking to store in the correct table. I can get the information to store in TblEmployee, however the information that I want to be stored in TblEquipment will not store in there.
I haven't been on Access for a while so im still in the process of getting the cogs turning....... i am trying to design a database structure for controllers and heating.
each controller can have many heating units each heating unit can use many controllers
rather than code everything, how could i set this up?
Example: Controller01 can be used with Boiler01, Boiler04, Boiler12, Boiler 20 Controller02 can be used with Boiler01, Boiler05, Boiler15 Controller03 can be used with Boiler02, Boiler03, Boiler04, Boiler20
I have a table with a ControllerID and a table with a BoilerID. In the boiler table, i have the ControllerID and a one to many relationship.
I am building a database for an activity society. There are 2 courses in each season, each course has 10 sessions. Students can be old (returning student)and new.
What we want to achieve is to check student information, the student's attendance situation, how many students in each session, etc.
The table I designed is:
1. Student Detail (student info) 2. Spring 2006 Sunday Course (student ID, payment, each session attendance...) 3. Spring 2006 Tuesday Course 4. Summer 2006 Sunday Course 5. Summer 2006 Tuesday Course . . . (each new course has a new table)
The problem is for each new course will need to add a new table. I just want to know if there is a better way to manage the data. Thanks for you help!
Hello All, At work we have a large and messy Contacts list so I decided to set one up using a database. At present I have 3 tables:- Companies (custID,companyname,address,etc) People (nameID,firstname,middlename,lastname,custID) Phones (phoneID,phonetype,areacode,number,?????)
My problem is this, Some of the phone nos belong to the individuals and some belong to the company. If a person is replaced at a company I need to reasign the company phone nos to the new person whilst retaining the individuals and their personal phone nos. If a company is deleted I need to delete only the company phone nos. and if a person moves within the company I want the company nos to reasign to the new replacement but keep the personal nos of the individual. Now I see its going to be more complex than I thought.
Can anyone help me with the table layout and links. (nb this is only a simple database relating a person to a company without using departments etc.) Its main use is to provide phone nos names and addresses quickly. Many Thanks Peter
I am designing a database to capture the data of returned surveys. I want to design the database to facilitate data analysis through crosstabs or other aggregation queries.
If I design a table where each record is the complete survey responses to all survey items in a returned survey, this is not friendly for such query analysis. (In this, each field would be a survey item). Call this the horizontal method.
The other way would be to have a reference table containing the survey items , and have responses entered in a seperate table linked by item id and response id (from a third table containing a record for each submitted survey). Call this the vertical method. This would take more time to set up but would probably be easier to query.
The item response table would become quite long contaiging every item response for every survey turned although each record is short.
Does anyone have any opinion on this, or perhaps a completely different approach that I haven't thought of that would be easy to set up but also easy to query?
I am trying to build a database for a local football team, and am having trouble with the design of the tables. The database contains numerous tables but my main problem is that within the database there are 4 types of people information:
Players:
(a player can have more than 1 guardian attached, eg mother, father, uncle, etc A player could also be a member of staff eg coach) Guradians of the players (a guardian can be attached to more than 1 player, eg two sons playing for the same club a guardian could be a member of staff, eg manager). Staff Members (A staff member can also be a guardian) Doctors (a doctor could be a staff member and also a guardian).
What is the best way to approach the design of these tables as i dont want to have to enter the same name, address details etc, more than once for if a person is in more then one of the people information categories.
The main focus of the database is driven by the player Information.
I want to show what guardians are responsible for each player, who the players doctor is, etc.
I have created a database table with 100+ fields with data. I now need to insert an additional 33 fields that will have a static default value between 1 and 33. I have already inserted the Line # field in the table between every 6 fields and gave it a default value. I now would like the existing database to update and reflect the new changes that were made for the new inserted fields.
I've designed a database at work to collate information about locations around the world that are contaminated by conflict and military activities. I'm struggling with the use of the lookup wizard to populate some fields in one table from another table.The database is ultimately meant to be used to identify contaminated sites in various countries and also to be a source of data for an online interactive map. As such, it needs to hold a fair amount of information. I figured that it would be normal that some fields and tables would be connected to one another. So, for example:
Country table is looked up by the conflict table to provide the names of countries participating in a conflict. To do so I used the lookup wizard. Similarly, the Site information table is looked up by the Site contamination event table to provide the names of contaminated sites. The Site contamination event table. Then the Site assessment table looks up the Site contamination event table to provide the name of contaminated sites. The relationship between these three table is intended so that at any given site multiple instances of contamination and their subsequent assessment can be recorded. This is where I started noticing problems. When I tried to input some fields into the Site assessment table, specifically the 'Site name', it would only display the primary and foreign keys in the drop down menu but not the 'Site name'.
- Have I messed up by relying on the lookup wizard in my table design? This seems to be the consensus in this and most forums (I checked another thread in the 'Tables' forum here). That said, I've seen some people making a distinction between using 'Lookup tables' and 'Lookup fields within a table', but given my relative newbyness I'm struggling to see the difference!
- If the answer is yes then what approach should I take to achieve the same aim (having multiple tables that feed information to one another). Initial research seems to suggest putting lookup/combo boxes in my forms. I'm dabbling with that at the minute but so far the results haven't been as desired.
I've attached a zip file with a screenshot of my relationships diagram to give an extra idea. Note that the relationship between the 'Site assessment' table and 'Site contamination event' table isn't showing up as I removed while trying to troubleshoot, but it is supposed to be one-to-many from 'Site contamination event' to 'Site assessment'.
I am planning my new DB and am contemplating the best design. It will be used for warehouse stock rotation and control of pallets. I want to track each pallet (product/time in/time out etc) to each pallet space within the warehouse. There are a total of 400 pallet spaces or 'locations' as i will refer to them as.
Now, would it be possible for me to have a table set up for each location? Will access object to having 400 tables in my data base?? Is there a limit?
The quantity band currently is fixed to 5 bands but would need to be flexible. There are also 2 prices for each of the quantity band (normal/special)
At the moment my table design looks like this:
ID fkSupplierID fkProductGroupID txtLayers (value list) intMinQty intMaxQty curNormalPrice curSpecialPrice
This works quite well with the query to return price based on product group, layer and order qty. However I am not very sure if this is the best way to design this. I am just thinking about maintenance - for example when the supplier puts in a price change or when the quantity band changes. The current format (quantity band) is based on a major supplier but in the future we would like to adopt this for any supplier.
I have a split database made in Access 2007. Each user gets their own copy of the frontend from a script. I wanted to be able to edit the design view of the backend tables even if people were using the database so I made all the forms use snapshot source and only allowed data updates through VBA macro update queries. Having any form open locks the backend source table from being edited. In fact, I've found that just having a normal snapshot query open causes the message "Either an object bound to table 'whatever' is open or another user has the table open. Do you want to open the table as read-only?"
Is there some way to have a table be the source for a form or query, but still have it designable under most circumstances?
Attempted to late-bind a recordset on form load; result was the same:
Code: Set rs = CurrentDb.OpenRecordset("Select redacted as ft from tblRedacted ", dbOpenSnapshot, dbReadOnly) Set Me.Recordset = rs Set rs = Nothing
Code: Private Sub Command26_Click() If Forms![test site]![prp test].Form.[A Right Answer] = -1 Then Forms![test site]![number correct] = Forms![test site]![number correct] + 1 End If DoCmd.FindNext End Sub
Then when clicked it checks a yes/no box to see if "A right Answer" is the correct yes. Then it should pop to the main form and take the number correct cell and add one to it. I am trying to get the record to go to the next record inside the sub-form but docmd.findnext seems to be wrong too.
we have Oracle 11g as main database and for viewing purpose, we have created an mdb (Access 2007) using Link tables via ODBC connection (system DSN).While querying, count queries are working fine with accurate record counts but, all select queries are not working fine. It filters and displays with wrong records. There is no issue in query building.how to get correct records through odbc connection to Oracle database.
I'm sorry if this is obvious, but I have asked local professionals and scoured this site for answers before posting...
I have a database that I'm using to store and analyze language samples (basically, the mistakes that students make when trying to speak in another language). For each bit of language, I want to be able to say what domain the mistake belongs to - e.g. the 'clause', 'phrase', or 'word' domain. I have a table containing the five domains. I also have a table for each of these domains, containing the specific types of mistakes relevant to that domain. It is conceivable, but unlikely, that I will ever add to the domain table, but highly likely that I will add types of mistakes in the five related tables.
As I analyze bits of language, I will be appending each analysis (record) to a table as shown in the attached image. So far so good. The part that I cannot fathom, though, is how to display (let alone perform calculations on) this data: While the ErrorDomainID is a foreign key to the ErrorDomain table, the ErrorUnitID could refer to one of five tables, so that an ErrorUnitID of 2, for example, could refer to one thing if the Domain is 1 but quite another if the domain is 1 or 5 or whatever.
I've tried all kinds of coding and SQL workarounds, but I have a feeling I'm just missing something very basic here. If anyone could offer some guidance, I'd be extremely grateful!
I have an order table and depending on the the product grp it needs to then be able to select the appropriate size scale table.
e.g.
I order suits, and select a size grade A ( there are 7 size grades ) I then then to enter the size scale for that product. I am not sure whether to create 7 differant tables with the different size grades and link that to the table, if so how do i get it select the correct table.

I am assisting my employer by combining two databases into one. Both databases have the same field "structure" but the data differs. When creating my append query.
I have a master table with all of my Site Names in it. I have a collection table that when a barcode is scanned it records the site name as being received. I built a query that counts the number of times the site name has been received.
What I want to do is list all of my sites from the master then display the count next to the corresponding site name. This will identify those sites that did not send in an item. Is there criteria in the query I could use so that 1) I could list all of my sites from the master table and then the count can be displayed from the collection table next to the correct Site Name?
So i split my database into a front and back end, now i wanted to add a table to the database. I created the table in the backend but im not sure how to make it appear in the front end. Im using access 2010. I tried the link table manager but the table i created dosent appear there.
All, using access 2010 but working on a 2003 database. Trying to import a table from another database. I made a copy of a database im trying to import from a database on a production server and placed it in my development folder. When I go to import the table; it throw an error:Reserved error (-1524); there is no message for this error.why I can't import a table especially if no one is using it?
what is the correct syntax to write a command line able to UPDATE more than one field in the table records having multiple WHERE criteria.
Here is my challenge:My TableI has the columns A, B, C and D which are populated, for example, as follows:
TableI A B C D 1 2 2 6 4 3
1 7 5 9 1 2 2 5 8 5 etc.
I also have a FormII which updates TableII. Among the existing fields of TableII there are the fields C and D (same as above). When saving data entry thru the save button of the FormII, fields C and D will be naturally saved on the TableII. Well, I also want C and D info updated into Table I as well, but only when field A=1 and B=2.So what I need (for the click event of the button save in the FormII) is to open TableI and either insert or update it with the values of the fields C and D in every record WHERE A=1 AND B=2.For instance, assuming C=& and D=%, the desired result should be as follows:
TableI A B C D 1 2 & % 2 6 4 3 1 7 5 9 1 2 & % 2 5 8 5
I did not find any examples in the net including multiple criteria..Here is what I wrote unsuccesfully:
Private Sub BtSalvarFrmII_Click() CurrentDb.execute "UPDATE TableI" Set FieldC = Forms!FrmII!FieldC.value AND Set FieldD = Forms!FrmII!FieldD.value WHERE FieldA = 1 AND FieldB = 2 Docmd.save Docmd.close End Sub
